巴甫洛夫的公牛
GMO 季度信函 2011 年 1 月 巴甫洛夫的牛 杰里米·格兰瑟姆
大约 100 年前,俄罗斯生理学家伊万·巴甫洛夫注意到,当喂食铃响起时,他的狗会在看到真正的食物之前就流口水。它们已被“条件反射化”。2008-09 年的“大刺激”也是如此。市场的玩家们在看到实际结果之前很久就已经流口水了。而市场像往常一样咆哮上涨。那是主餐。但进入总统周期第 3 年的茶歇铃在 10 月 1 日敲响了。自 1964 年以来,“例行”的第 3 年刺激措施帮助推动标普 500 指数在扣除通胀后惊人地上涨了 23%。而这一次,茶里还加了 QE2 的香料。道德风险被证明依然活跃,狗们跃跃欲试。市场像灰狗一样冲出起跑门,已经飙升了 13%(截至 1 月 12 日),轻松超过了第 3 年的平均水平(+9%)。与往常一样,投机性股票表现更好,罗素 2000 指数飙升了近 19%。我们都是训练有素的市场之狗,按提示流口水,行为完全符合预期。自由意志——不过如此!
GMO QUARTERLY LETTER January 2011 Pavlov’s Bulls Jeremy Grantham About 100 years ago, the Russian physiologist Ivan Pavlov noticed that when the feeding bell was rung, his dogs would salivate before they saw the actual food. They had been “conditioned.” And so it was with “The Great Stimulus” of 2008-09. The market’s players salivated long before they could see actual results. And the market roared up as it usually does. That was the main meal. But the tea-time bell for entering Year 3 of the Presidential Cycle was struck on October 1. Since 1964, “routine” Year 3 stimulus has helped drive the S&P up a remarkable 23% above any inflation. And this time, the tea has been spiced with QE2. Moral hazard was seen to be alive and well, and the dogs were raring to go. The market came out of its starting gate like a greyhound, and has already surged 13% (by January 12), leaving the average Year 3 in easy reach (+9%). The speculative stocks, as usual, were even better, with the Russell 2000 leaping almost 19%. We have all been well-trained market dogs, salivating on cue and behaving exactly as we are expected to. So much for free will!
近期预测……时不时地,我们有个习惯,就是在一个重要的市场阶段回顾一下我们的预测是否准确。我会尽量简短:我们的预测能力在巴甫洛夫式的牛市面前表现如何?嗯,直说吧,总体原则上堪称精彩;我们在 2009 年第一季度致股东信中就预言了它的轮廓,并反复警告第三年的可能强度。但具体细节上,我们却相当令人失望。
Recent Predictions … From time to time, it is our practice to take a look at our predictive hits and misses in an important market phase. I’ll try to keep it brief: how did our prognostication skill stand up to Pavlov’s bulls? Well, to be blunt, brilliantly on general principle; we foretold its broad outline in my 1Q 2009 Letter1 and warned repeatedly of the probable strength of Year 3. But we were quite disappointing in detail.
好消息是……对于一个过去 20 年(不可否认市场总体高估)基本持悲观态度的人来说,我对这轮反弹在宏观层面大致判断正确。我在 2009 年一季度信函中写道:“我暂时与许多看空盟友分道扬镳……面对美国历史上力度最大的货币与财政刺激,我们完全可能迎来一场强劲的市场响应……很可能会出现一次引人注目的股市反弹,其幅度远超短期或长期经济基本面的任何合理支撑……[股指]会远超合理估值(当时 880 点),在今年年底前涨到 1000-1100 点左右。”因此,在传统的平衡型账户中,我们将全球股票持仓从 2008 年 10 月的历史最低 38% 提高到 2009 年 3 月的 62%。(不过,事后看,如果当时提到 72% 才更合理。)同一封信中,我对经济的判断是:“当前全球范围的刺激力度如此之大,肯定会在今年年底前至少让包括美国和中国在内的一些大国经济重新启动……”
The Good News … For someone who has been mostly bearish for the last 20 years (of admittedly generally overpriced markets), I got this rally more or less right at the macro level. In my 1Q 2009 Letter, I wrote, “I am parting company with many of my bearish allies for a while ... we could easily get a prodigious response to the greatest monetary and fiscal stimulus by far in U.S. history ... we are likely to have a remarkable stock rally, far in excess of anything justified by either long-term or short-term economic fundamentals … [to] way beyond fair value [then 880] to the 1000-1100 level or so before the end of the year.” As a consequence, in traditional balanced accounts, we moved from an all-time low of 38% in global equities in October 2008 to 62% in March 2009. (If only that had been 72%, though, as, in hindsight, it probably should have been.) In the same Letter, I said of the economy, “The current stimulus is so extensive globally that surely it will kick up the economies of at least some of the larger countries, including the U.S. and China, by late this year ...”
在基本面的一部分上,我们反倒完全错了。关于潜在问题,我当时写道:“最不容忽视的,是利润率面临的下行压力——过去 20 年里,利润率一直得益于资产价格上涨悄悄渗入其中。”我为什么错得这么离谱,我说不清楚,因为我至今仍然不明白,美国怎么会在劳动力和工业产能大量闲置的情况下,利润率却处于历史峰值。这种情况以前从未发生过。事实上,在格林斯潘之前,利润率与产能之间存在着强烈的正向相关关系,方向符合预期。这正是我们在资产配置中强烈怀疑这些丰厚利润根基的原因之一。我们仍然预期利润率会回归到更正常的水平。
On one part of the fundamentals we were, in contrast, completely wrong. On the topic of potential problems, I wrote, “Not the least of these will be downward pressure on profit margins that for 20 years had benefited from rising asset prices sneaking through into margins.” Why I was so wrong, I cannot say, because I still don’t understand how the U.S. could have massive numbers of unused labor and industrial capacity yet still have peak profit margins. This has never happened before. In fact, before Greenspan, there was a powerful positive correlation between profit margins and capacity in the expected direction. It is one of the reasons that we in asset allocation strongly suspect the bedrock on which these fat profits rest. We still expect margins to regress to more normal levels.

1 “The Last Hurrah and Seven Lean Years,” 1Q 2009 Quarterly Letter.
在资源价格这个话题上,我的长期看法过去是,现在依然是,非常乐观。不是说我不预期偶尔会有恶性回调——这就是事物的本性。我在 2009 年第二季度信函中写道:“我们正以危险的速度耗尽一切……我们必须做好准备,迎接比战时就局面更严峻的资源价格上涨和供应短缺浪潮。”
On the topic of resource prices, my long-term view was, and still is, very positive. Not that I don’t expect occasional vicious setbacks – that is the nature of the beast. I wrote in my 2Q 2009 Letter, “We are simply running out of everything at a dangerous rate ... We must prepare ourselves for waves of higher resource prices and periods of shortages unlike anything we have faced outside of wartime conditions.”
为向美联储惊人的市场调控能力致敬,我在连续几个季度中坚持认为,市场的“最小阻力线”是向上的——到 2011 年 10 月,标普 500 指数将升到 1500 点区间。只要市场和经济能扛住二次探底这种较小概率的风险,这个展望就站得住。从基本面看,我仍然相信,发达经济体的增速会稳定在尚可但低于过去的水平,而我们正在艰难地穿越我的“七年匮乏期”。在这个问题上,我们面临三重威胁:1)住房、商业地产以及(在某种程度上仍存在的)股市带来的财富损失,这导致债务滞留并产生负财富效应;2)劳动年龄人口增长率放缓;3)大宗商品价格上涨和资源稀缺期增多,极端天气会加剧这一状况。要判断这个预测的准确性还需要些时间,但从初期情况已经可以看清,这是重大经济衰退之后最糟糕的一次复苏,尤其是在就业创造方面。
In homage to the Fed’s remarkable powers to move the market, I argued in successive quarters that the market’s “line of least resistance” was up – to the 1500 range on the S&P by October 2011. That outlook held if the market and economy could survive smaller possibilities of double-dips. On fundamentals, I still believe that the economies of the developed world will settle down to growth rates that are adequate, but lower than in the past, and that we are pecking our way through my “Seven Lean Years.” We face a triple threat in this regard: 1) the loss of wealth from housing, commercial real estate, and still, to some extent, the stock market, which stranded debt and resulted in a negative wealth effect; 2) the slowing growth rate of the working-age population; and 3) increasing commodity prices and periods of scarcity, to which weather extremes will contribute. To judge the accuracy of this forecast will take a while, but it is clear from the early phases that this is the worst-ever recovery from a major economic downturn, especially in terms of job creation.
再说坏消息……我们曾指出,优质股票——即拥有强大经济特许权的公司——是最便宜的股票类别。在任何单一年份,便宜往往是一根靠不住的稻草,2009 年和去年(2010 年)正是如此,结果是高品质股票遭遇了有史以来最惨烈的打击之一。我们已多次坦白过一项罪过:在美联储主导的市场中,未能对风险较高的股票之美更加开放。以价值之名,我们的业绩跑输了。回顾这段经历,我们觉得,如果在 2009 年 3 月之后至少转向更高比例的风险投资,本应是合理的,因为其中一些——尤其是新兴市场股票——其估值确实几乎和优质股票一样高。实际上,有些甚至完全落入了我们正常的估值误差范围之内,当然,优质股票不仅最便宜,而且风险最低——这往往是一个令人敬畏的组合。但即便我们在低点做了那样的调整,到 2010 年初更加极端的价值背离也会迫使我们回到当前位置——大幅超配优质股票——这个头寸我们已经持有了好几年。2009 年持续大幅超配优质股票,在智识上和其他方面都令人痛苦。2010 年的痛苦更接近“照常营业”,等待着价值的美德被揭示。唯一的安慰是,虽然价值在任何单一年份都是一种微弱的力量,但在几年时间里它会变成一头猛兽。就像重力一样,它慢慢地消磨掉对手。
And the Bad News … We pointed out that quality stocks – the great franchise companies – were the cheapest stock group. Cheapness in any given year is often a frail reed to lean upon, and so it was in 2009 and again last year, resulting in about as bad a pasting for high quality as it has ever had. We have already confessed a few times to the crime of not being more open to the beauties of riskier stocks in a Fed-driven market. And in the name of value, we underperformed. Reviewing this experience, we feel that it would have been reasonable to have shifted to at least an increased percentage of risky investments after March 2009, because some of them, notably emerging market equities, did have estimates almost as high as quality. In fact, some were well within the range of our normal estimating error, although, of course, quality stocks were not only the least expensive, they were also the least risky, often a formidable combination. But even if we had made such a move at the lows, more extreme value discrepancies by early 2010 would have compelled us to move back to our present position – heavily overweight quality stocks – that we have carried for several years. Our sustained heavy overweight in quality stocks in 2009 was painful, intellectually and otherwise. Our pain in 2010 was more “business as usual,” waiting for the virtues of value to be revealed. The saving grace is that, although value is a weak force in any single year, it becomes a monster over several years. Like gravity, it slowly wears down the opposition.
基本面因素同样对优质公司不利,低质量公司和小盘股反而实现了更好的盈利。这类公司通常对美联储类的刺激政策反应更佳。但正如价值投资中的其他要素一样,利润率总是无情地回归其长期均值,或者说几乎总是如此。
The fundamentals have also worked against quality, with lower quality companies and small caps posting better earnings. They typically respond better to Fed-type stimulus. But like other components of value, profit margins always move remorselessly back to their long-term averages, or almost always.
2011 年 1 月
那么,我们现在处于什么位置?尽管“优质”股票非常便宜,而小盘股非常昂贵(低质量公司也是如此),但我们正处于总统周期第三年,高风险——尤其是高波动性,但也包括所有与风险相关的品种——通常表现出色,而优质资产表现不佳。这并非我们需要的局面!再次令人缓和的有利因素是极端的价值落差对我们有利,但在第三年,这一点从未如此不重要。这是价值型基金经理面临的永恒困境:我们多少可以确信优质资产会在几年内胜出,但它很可能在接下来的几个季度里表现落后。我们一直认为应该更倚重长期高确定性的判断。简单来说,只要短期利率维持在低位,市场往往会上涨。这种情况很可能再持续八个月,因此我们必须为市场上涨和风险偏好抬头做好准备。因此,我们一直在研究以往的股市泡沫——如果标普 500 指数涨到 1500 点,那么它将正式成为最新一轮真正的泡沫。所有著名的泡沫都破裂了,但只有在短期利率开始上升之后,有时还会持续相当一段时间。我们只找到了几个不重要的、40 年一遇的两个标准差的小泡沫,在利率下降期间破裂——那是将近 50 年前的事了。那些非常著名、规模巨大的泡沫也常常给出另一种警告。投资者或许知道自己在悬崖边跳舞,却又难以停下来,在泡沫后期,他们往往会转向更安全的股票,而风险股则因表现落后而暴露出高贝塔值的本性。我们可以另找时间细谈,但可以说,泡沫破裂之前通常会有警告,有时甚至多次警告。估值过高是定义泡沫的必要条件,但它本身并不是有用的警示信号。我担心今年资源价格上涨可能导致一些新兴国家出现严重通胀。理论上,这可能阻止正在美国股市形成的泡沫进一步发展。实际上,在利率至少开始上升之前,这不太可能阻止我们的市场。考虑到资产价值下跌仍留下通货紧缩的气息、持续疲软的房市、低迷的就业和极低的劳动力成本,美国出现通胀恐慌似乎还很遥远。
January 2011 So, where are we now? Although “quality” stocks are very cheap and small caps are very expensive (as are lower quality companies), we are in Year 3 of the Presidential Cycle, when risk – particularly high volatility, but including all of its risky cousins – typically does well and quality does poorly. Not exactly what we need! The mitigating feature once again is an extreme value discrepancy in our favor, but this never matters less than it does in a Year 3. This is the age-old value manager’s dilemma: we can more or less depend on quality winning over several years, but it may well underperform for a few more quarters. We have always felt we should lean more heavily on the longer-term higher confidence. As a simple rule, the market will tend to rise as long as short rates are kept low. This seems likely to be the case for eight more months and, therefore, we have to be prepared for the market to rise and to have a risky bias. As such, we have been looking at the previous equity bubbles for, if the S&P rises to 1500, it would officially be the latest in the series of true bubbles. All of the famous bubbles broke, but only after short rates had started to rise, sometimes for quite a while. We have only found a couple of unimportant two-sigma 40-year bubbles that broke in the midst of GMO 2 Quarterly Letter – Pavlov's Bulls – January 2011 declining rates, and that was nearly 50 years ago. The very famous, very large bubbles also often give another type of warning. Probably knowing they are dancing close to the cliff and yet reluctant to stop, late in bubbles investors often migrate to safer stocks, and risky stocks betray their high betas by underperforming. We can get into the details another time, but suffice it to say that there are usually warnings, sometimes several, before a bubble breaks. Overvaluation must be present to define a bubble, but it is not a useful warning in and of itself. I fear that rising resource prices could cause serious inflation in some emerging countries this year. In theory, this could stop the progress of the bubble that is forming in U.S. equities. In practice, it is unlikely to stop our market until our rates have at least started to rise. Given the whiffs of deflation still lingering from lost asset values, the continued weak housing market, weak employment, and very contained labor costs, an inflationary scare in the U.S. seems a ways off.
大宗商品、天气与市场。气候与天气很难截然分开。我的建议是:忽略一切尚未打破历史纪录、不在新纪录清单中的东西。去年,有史以来最热的日子在全球各地频繁出现,2010 年与 2005 年并列成为全球有记录以来最热的年份。在气候学家看来,俄罗斯的热浪与巴基斯坦的洪水——两者均创下纪录——显然相互关联。然而,也许最引人注目的是澳大利亚的情况:在经历了七年严重干旱之后,一片相当于德国与法国面积之和的土地被淹没在几英尺深的水下。这完全超出了人们的经验范围,被形容为“圣经级的大洪水”。更贴近投资角度的要点是:俄罗斯热浪影响小麦价格,澳大利亚洪水则同时干扰采矿与农作物生产。因天气而导致的作物收成令人失望,似乎正变得司空见惯。这种极端天气模式,恰恰是科学界所预测的结果。国会山上的积雪——尽管被一些真正愚蠢且信息闭塞的国会议员当作攻击对方的炮弹——也完全符合这一趋势。天气的不稳定性,始终是全球变暖最直观的副作用。
Commodities, Weather, and Markets Climate and weather are hard to separate. My recommendation is to ignore everything that is not off the charts and in the book of new records. The hottest days ever recorded were all over the place last year, with 2010 equaling 2005 as the warmest year globally on record. Russian heat and Pakistani floods, both records, were clearly related in the eyes of climatologists. Perhaps most remarkable, though, is what has been happening in Australia: after seven years of fierce drought, an area the size of Germany and France is several feet under water. This is so out of the range of experience that it has been described as “a flood of biblical proportions.” More to the investment point: Russian heat affects wheat prices and Australian floods interfere with both mining and crops. Weather-induced disappointment in crop yield seems to be becoming commonplace. This pattern of weather extremes is exactly what is predicted by the scientific establishment. Snow on Capitol Hill, although cannon fodder for some truly dopey and ill-informed Congressmen, is also perfectly compatible. Weather instability will always be the most immediately obvious side effect of global warming.
最后一个故事,虽然远非严谨的科学,但至少对我来说很有趣;我支持新英格兰水族馆正在进行的关于露脊鲸的研究(之所以叫这个名,是因为它实在太适合捕捞、宰杀并炼成鲸油了)。一个月前,我们和露脊鲸专家共进午餐——这可是最新消息!——得知了一个新进展。大约 350 头露脊鲸(现存总数约 500 头,而最初至少有数十万头)通常会在夏末现身芬迪湾,进行为期数周的觅食。今年,这项研究进行了 30 年来头一次,它们“爽约”了。沿着海岸一路查问,他们只找到了 100 头(每头都通过外观辨认,没有一头在任何地方停留超过一两天)。人们希望这仅仅是它们的食物供应转移到了别处。原因未知,可能需要数年才能确定,但最可能的候选因素是,来自(主要是)格陵兰岛融冰的额外寒冷淡水改变了洋流,或以其他方式干扰了它们食物的位置。如果原因确实是加速的融冰径流,那么这完全符合另一个早已确立的假说:来自格陵兰岛的额外寒冷淡水可能会冷却墨西哥湾流,这条向英国和北欧输送热量的巨大传送带。如果真是这样,那么伦敦一觉醒来,会发现自己的感觉更像蒙特利尔——两者大约处于同一纬度——而不是它习惯的那样,比如说,就会产生所有旅行者今天都在读的那种冬天。
One last story, which is far from hard science, but to me at least intriguing; I support research being done by the New England Aquarium on the right whale (so called because it was just perfect for catching, killing, and turning into whale oil). We had lunch with the right whale expert one month ago – hot off the press! – and were informed of a new development. Three hundred and fifty or so right whales (out of the remaining population of some 500, down from at least hundreds of thousands), have always shown up in late summer for several weeks of feeding in the Bay of Fundy. This year, for the first time in the 30 years of the study, they were “no shows.” Calling up and down the coast, they were able to locate only 100 of them (all known by sight as individuals; none of which stayed more than a day or two anywhere). It is hoped that their food supply had simply moved to another location. The cause for this is unknown and may take years to be very confident of, but the most likely candidate is that extra cold fresh water run-off from melting ice, mainly Greenland, had shifted currents or interfered in other ways with the location of their food. If indeed the cause were accelerated run-off, then this would be completely compatible with another long-established hypothesis: that extra cold fresh water from Greenland might cool the Gulf Stream, the great conveyor of heat to Great Britain and Northern Europe. If this were in fact the case, then London would wake up and find itself feeling a lot more like Montreal – on about the same latitude – than it is used to, producing, for example, the winter there that all travelers are reading about today.
你是第一个读到这个消息的人,保守的科学家们也许会在两年或更久之后,才在学术期刊上把它写出来。然而,这是一个绝妙的简单例子,说明北方冰雪中的暖冬可能如何破坏了系统的稳定,最终导致北欧严寒。
You read it here first, and conservative scientists will perhaps be writing it up in a learned journal in two or more years. It is, though, a wonderfully simple example of how a warm winter in the Northern ice might have destabilized systems, ultimately resulting in a frigid Northern Europe.
资源限制说明
在我看来,因天气不稳定而加剧的资源问题,将是未来数年我们面临的最大、最复杂的投资问题。我们该如何准备?首先,我们都应该把更多的智力资源转移到这个问题上。是的,我们已经推荐过林业、农田和“地里的东西”。如果能用更多细节来支持这一点,那就更好了。为此,我们开始更仔细地研究季度信函——巴甫洛夫的多头——2011 年 1 月 3 日 GMO 大宗商品周期,无论是历史上的还是当前的。我们会时不时地汇报进展。
Resource Limitation Note For my money, resource problems exacerbated by weather instability will be our biggest and most complicated investment problem for years to come. How should we prepare for it? First, we should all transfer more of our intellectual resources to the problem. Yes, we have already recommended forestry, agricultural land, and “stuff in the ground.” It would be nice to back this up with more detail. To this end, we are starting to look more closely at Quarterly Letter – Pavlov's Bulls – January 2011 3 GMO commodity cycles, both historically and currently. We will report back from time to time.
顺便说一句,好消息是,我们始于 1998 年的长期泡沫研究已经变得庞大无比。从前只是研究少数几个著名的、公认的投资泡沫,现在我们正深入进行一项统计上严谨的审查,涵盖一级、二级,甚至可能是三级泡沫,目前已经统计了惊人的 320 个完整的泡沫。目前,我们不打算公开完整的审查报告,但几个月后我们会回顾一些有趣的“平均”泡沫行为。
By the way, the good news is that our long-term bubble study, started in 1998, has become a monster. Formerly a study of the handfuls of famous, accepted investment bubbles, we are now well into a statistically rigorous review of primary, secondary, and possibly even tertiary bubbles, and now count a stunning 320 completed bubbles. For now, we do not intend to make our complete review generally available, but we will review some interesting “average” bubble behavior in a few months.
所以,我们确实知道一些关于大宗商品的有用信息。复杂之处在于,最近几年,大宗商品似乎正在经历一场范式转移。如果真是这样,这将是迄今为止最重要的范式转移。坏消息是,范式转移,就其定义而言,无法用历史很好地描述。这完全取决于判断。现在这才是真正的问题。
So, we do know some useful stuff about commodities. The complicating point is that in the recent few years, commodities seem to be making a paradigm shift. If this is so, it will be the most important paradigm shift to date. The bad news is that paradigm shifts cannot, by definition, be described well using history. It is all about judgment. Now there’s a real problem.
展望未来
▪ 为强劲的市场以及所有风险资产继续跑赢大盘做好准备。
▪ 但要知道,作为多头,你是在借来的时间里活着;根据我们的数据,市场在标普 500 指数上大约值 910 点,远低于当前水平,而且大多数风险成分的定价甚至更高。
▪ 今年当市场进入危险的高估区域时,你从市场中撤出的速度更像一门艺术,而非科学,但到 10 月 1 日,你或许应该考虑更为保守的策略。
▪ 和以前一样,我们认为,美国优质股票是定价最不高的股票。
▪ 要想从现在起在新兴市场赚钱,动物精神必须保持强劲,而且不能出太多差错。这可能是长达 12 年热恋的最后一章。新兴市场股票似乎正处于“新兴的、新兴泡沫”的早期阶段,我在 3 年半前就曾预言它会到来。泡沫能膨胀到多大,谁也说不准,但从现在起,我们必须更加小心。
▪ 对于我们这些做资产配置的人来说,目前货币太不确定,难以选择。偶尔,我们认为,有一种或几种货币会严重偏离轨道。但眼下不是这种情况。
▪ 资源股,比如“地里的东西”,很可能是不错的长期投资。但短期内,它们确实会毁掉一个季度,而且它们最近肯定已经涨了很多。
▪ 我们认为林业仍然是一个不错、安全的长期投资。优质的农田也是如此。
▪ 需要警惕的是:未来几个月,大宗商品价格的上涨可能如此之大,以至于新兴经济体的政府政策可能会终结全球股市牛市。不过,我猜测,在美国目前还不是这样。
Looking Forward Be prepared for a strong market and continued outperformance of everything risky. But be aware that you are living on borrowed time as a bull; on our data, the market is worth about 910 on the S&P 500, substantially less than current levels, and most risky components are even more overpriced. The speed with which you should pull back from the market as it advances into dangerously overpriced territory this year is more of an art than a science, but by October 1 you should probably be thinking much more conservatively. As before, in our opinion, U.S. quality stocks are the least overpriced equities. To make money in emerging markets from this point, animal sprits have to stay strong and not much can go wrong. This is possibly the last chapter in a 12-year love affair. Emerging equities seem to be in the early stages of the “Emerging, Emerging Bubble” that, 3½ years ago, I suggested would occur. How far a bubble expands is always anyone’s guess, but from now on, we must be more careful. For those of us in Asset Allocation, currencies are presently too iffy to choose between. Occasionally, in our opinion, one or more get far out of line. This is not one of those occasions. Resource stocks, as in “stuff in the ground,” are likely to be fine investments for the very long term. But short term, they can really ruin a quarter, and they have certainly moved a lot recently. We think forestry is still a good, safe, long-term play. Good agricultural land is as well. What to watch out for: commodity price rises in the next few months could be so large that governmental policies in emerging countries might just stop the global equity bull market. My guess, though, is that this is not the case in the U.S. just yet.
2011 年及以后真正重要的事情(一家之言)——投资与现实生活
▪ 资源枯竭,对大宗商品价格形成强劲但间歇性的压力
▪ 全球变暖导致天气模式不稳定,加剧农业价格压力
▪ 美国教育标准相对于竞争对手下降
▪ 巨大的收入差距以及美国小时工资缺乏进展
▪ 其他所有事情。
Things that Really Matter in 2011 and Beyond (in one person’s view) for Investments and Real Life Resources running out, putting strong but intermittent pressure on commodity prices Global warming causing destabilized weather patterns, adding to agricultural price pressures Declining American educational standards relative to competitors Extraordinary income disparities and a lack of progress of American hourly wages Everything else.
GMO 4 季度信函——巴甫洛夫的多头——2011 年 1 月
附言
最近,GMO 董事会的一位同事问我,我是如何决定写什么的。嗯,我绝对不是想评论所有重要、甚至所有有趣的话题。读者常常对我回避什么感到惊讶——我可以说,这相当合理。
GMO 4 Quarterly Letter – Pavlov's Bulls – January 2011 Postscript I was recently asked by a colleague on the GMO Board how I decide what to write about. Well, I’m most decidedly not trying to comment on all-important, or even all-interesting, topics. Readers are often surprised – quite reasonably, I might add – at what I avoid.
我一直努力专注于少数几个我了解得相当深入的问题。这主要是识别股票市场中那些严重错误定价的主要板块或资产类别。多年来,这发展成对泡沫和崩盘的研究。随着我们积累数据和进行分析,我(以及我们)的知识和舒适区扩展到其他资产类别中的类似异常事件,包括货币、大宗商品、债券和一些房地产市场。不过,规则是,除非这些非股票价格序列的定价确实极端,否则不要贸然出头,这一策略,希望如此,给了我们一个不错的安全边际。在股票方面,我们更大胆一些,有时也为过早行动付出了高昂代价。但我们很少,如果有的话,错过重大的错误定价。
I have always tried to focus on the handful of issues about which I know a decent amount. This has been overwhelmingly about identifying hugely mispriced major sectors or asset classes among equities. This developed over the years into a study of bubbles and busts. As we built up our data and analysis, my (and our) knowledge and comfort zone extended to similar outlier events in other asset classes, including currencies, commodities, bonds, and some real estate markets. The rule, though, was not to stick our necks out unless the pricing is truly extreme for these non-equity price series, a policy that has given us, touch wood, a good safety margin. In equities, we have been a little braver and sometimes paid a high price for being early. But we missed very few, if any, major mispricings.
其次,几十年来,我们研究了所有其他股市倾向,从崇高的到(我承认)荒谬的。因此,总统周期和一月效应被视为值得研究的课题,同时还有对各种东西定价的理论,以及研究动量和其他因素对定价行为的影响。最终,对于股票,这变成了一个相当包容的问题:市场是如何运作的?在股票或泡沫之外,我通常不认为自己的理解足以证明我严肃评论是合理的。尽管我偶尔也这么做。我提供的绝大多数其他意见都源于这组数据。例如,我对美联储的强烈看法,关键在于他们明显忽视了允许资产泡沫形成的意义和危险,其次也基于我们对他们引发的第 3 年总统效应的了解。
Second, we have studied all other equity market tendencies over the decades, from the sublime to (I confess) the ridiculous. Thus, Presidential Cycles and January Rules were considered fair game for research, along with theories for valuing everything and studying the effects of momentum and other factors on pricing behavior. In the end, for equities, this became a pretty inclusive question: how do markets work? Outside of equities or bubbles, I do not usually consider my understanding sufficient to justify my commenting seriously. Although I do occasionally. Most other opinions I’ve offered have had this body of data as their source. For example, my strong views on the Fed hinged on their obvious missing of the significance and dangers of allowing asset bubbles to form and also, to a lesser degree, on our knowledge of the Year 3 Presidential effect, which they cause.
在极少数情况下,我觉得自己对整体经济或金融图景中非常小的一部分有一些见解,这通常是基于我所认为的常识,而非详尽的知识。但总的来说,我觉得许多投资专业人士犯了一个错误,就是把自己当成经济学家或银行业专家。他们对市场的直觉通常非常出色,这应该足以让他们感到满意。
On some very rare occasions, I feel that I have some insight into a very small part of the general economic or financial picture, usually based on what I see as common sense as opposed to detailed knowledge. In general though, I feel that many investment pros make the mistake of thinking of themselves as economists or banking experts. Their feel for markets is often excellent, and should be enough to keep them happy.
无论如何,这是我的观点,它让我避免对任何数量有趣且重要的问题发表评论(或者至少是严肃的评论)。今天要回避的领域包括:通胀与通缩、如何在不引发通胀的情况下精确地摆脱高债务、一般利率、特别是信贷、货币的微妙之处、任何银行细节、政治、医疗保健、理想的贸易政策、税收政策,等等等等。所以请不要因为我不谈论某个问题,就认为我觉得它不重要。我不觉得。
This is my view, anyway, and it leads me to avoid comment (or serious comment, anyway) on any number of interesting and important issues. Such areas of avoidance today would include inflation versus deflation, how precisely to extricate ourselves from high debt without causing inflation, interest rates in general, credit in particular, subtleties of currency, any banking nuance, politics, health care, desirable trade policy, tax policy, etc., etc. So please don’t think I believe it’s unimportant if I ignore an issue. I don’t.

第二部分:论资产类别泡沫对价值投资者的重要性及其成因
杰里米·格兰瑟姆
为给第二部分搭建舞台,让我重复第一部分开篇的一段话:“我也对格雷厄姆–多德派深感恼火,因为他们竟从 75 年前那本伟大的《证券分析》中推论出,泡沫和崩盘是可以忽略的。他们认为,你不需要处理这类事情,只需埋头专注于选股就行了。他们觉得,识别泡沫带有一丝投机和不可取的味道。我今天尤其要攻击的正是这个想法,因为我处于光谱的另一端:我相信,投资中唯一真正重要的东西就是泡沫和崩盘。而在某个国家、某个资产类别里,通常总有与泡沫相关的有趣事情正在发生。”¹
继续讨论资产泡沫及其形成方式,便引出了图表 1。它展示了我认为市场是如何运作的。记住,谈到市场运作时,凯恩斯真的搞懂了。职业风险驱动着机构世界。从根本上说,每个人的行为就好像他们的职位描述就是“保住它”。凯恩斯完美地解释了如何保住你的饭碗:永远、永远不要独来独往。
Part 2: On the Importance of Asset Class Bubbles for Value Investors and Why They Occur Jeremy Grantham To set the scene for Part 2, let me repeat some of my opening paragraph from Part 1: “I’ve also been pretty irritated by Graham-and-Doddites because they have managed to deduce from a great book of 75 years ago, Security Analysis, that somehow bubbles and busts can be ignored. You don’t have to deal with that kind of thing, they argue, you just keep your nose to the grindstone of stock picking. They feel there is something faintly speculative and undesirable about recognizing bubbles. It is this idea, in particular, that I want to attack today, because I am at the other end of the spectrum: I believe the only things that really matter in investing are the bubbles and the busts. And here or there, in some country or in some asset class, there is usually something interesting going on in the bubble business.”1 Moving on to asset bubbles and how they form brings us to Exhibit 1. It shows how I think the market works. Remember, when it comes to the workings of the market, Keynes really got it. Career risk drives the institutional world. Basically, everyone behaves as if their job description is “keep it.” Keynes explains perfectly how to keep your job: never, ever be Exhibit 1 The Way the Investment World Goes Around: They Were Managing Their Careers, Not Their Clients’ Risk Keynes Career Risk Herding & Timing Momentum Uncertainty + Extrapolation Arbitrage or Market Mean Reversion Inefficiency Prices Move Away Risk / Return from Fair Value Pulls Prices Back to Fair Value Graham & Dodd * The Letters to the Investment Committee series is designed for a very focused market: members of institutional committees who are well informed but non-investment professionals.
第一部分:“朋友们,罗马人,我来是为了调侃格雷厄姆和多德,而不是赞美他们,”这段话出自杰里米·格兰瑟姆 2010 年第一季度致客户信,该信函可在 www.gmo.com 网站的资料库中查阅到。
1 Part 1: “Friends and Romans, I come to tease Graham and Dodd, not to praise them,” appears in Jeremy Grantham’s 1Q 2010 Quarterly Letter, which is avail-able in the Library at www.gmo.com.
自己犯错不行,和别人一起犯错就没事。比如说,在最大的 30 家金融公司里,每一家的 CEO 都没能预见次贷危机及其随之而来的必然风暴。不出所料,他们大喊“没人预见到这事儿!”——可我们明明知道大概有 30 来位策略师、经济学家、撰稿人等早就看到了。不过话又说回来,那些跟着别人跳崖的人,只要没犯别的什么大错,基本上还算安全;错过这场迫在眉睫的危机,显然远远不够让他们被炒鱿鱼。凯恩斯说得对:“唉,一个称职的银行家,不是那种能预见风险并避开的人,而是那种即便栽了,也是以传统正统的方式和同伙一起栽跟头,这样谁都怪不到他头上的人。”² 所以,你要做的就是环顾四周,看看别人在干什么,然后如果你想成功,就比他们先下手。
wrong on your own. You can be wrong in company; that’s okay. For example, every single CEO of, say, the 30 largest financial companies failed to see the housing bust coming and the inevitable crisis that would follow it. Naturally enough, “Nobody saw it coming!” was their cry, although we knew 30 or so strategists, economists, letter writers, and so on who all saw it coming. But in general, those who danced off the cliff had enough company that, if they didn’t commit other large errors, they were safe; missing the pending crisis was far from a sufficient reason for getting fired, apparently. Keynes had it right: “A sound banker, alas, is not one who foresees danger and avoids it, but one who, when he is ruined, is ruined in a conventional and orthodox way along with his fellows, so that no one can really blame him.”2 So, what you have to do is look around and see what the other guy is doing and, if you want to be successful, just beat him to the draw.
动作更快、更灵活。如果每个人都盯着别人看别人怎么做,以求降低自己的职业风险,那就会出现羊群效应。我们所有人都会先朝一个方向猛冲,然后又朝另一个方向猛冲。由此产生的巨大动量,在每一种金融资产类别中都可测量,而且历来如此。有时动量的周期会发生变化,但它始终存在。这是市场中最大的一类低效。低效有很多种,可能有上百种,但压倒性最强的一种就是动量(基于完全理性的原因,保罗·伍利 3 会这样说:保住饭碗的行为是理性的)。但它并不能创造一个有效的市场。事实上,从很多方面看,这种羊群效应可能恰恰是低效的,甚至是功能失调的。
Be quicker and slicker. And if everyone is looking at everybody else to see what’s going on to minimize their career risk, then we are going to have herding. We are all going to surge in one direction, and then we are all going to surge in the other direction. We are going to generate substantial momentum, which is measurable in every financial asset class, and has been so forever. Sometimes the periodicity of the momentum shifts, but it’s always there. It’s the single largest inefficiency in the market. There are plenty of inefficiencies, probably hundreds. But the overwhelmingly biggest one is momentum (created through a perfectly rational reason, Paul Woolley3 would say): acting to keep your job is rational. But it doesn’t create an efficient market. In fact, in many ways this herding can be inefficient, even dysfunctional.
凯恩斯对外推法也有论述——这种方法对动量策略极其关键。他说,外推法是我们为应对不确定世界而采取的一种“惯例”,尽管我们凭个人经验就知道,这种做法远谈不上稳定。换句话说,从定义上讲,只要你做出任何形式的预测,就是在承担职业风险。为了应对这种风险,经济学家们会煞费苦心地让预测保守些,直到看到别人的预测数字。你可以看到,经济学家们的预测值总是扎堆在一起;即便经济已经坠下悬崖,他们每月也只将预测下调 30 个基点,而不是在第一个月就一把砍掉 300 个基点。这样,他们就能看看别人在做什么。于是他们下调 30 个基点,环顾四周,再下调 30 个基点,如此循环。
Keynes also had something to say on extrapolation, which is very central to the process of momentum. He said that extrapolation is a “convention” we adopt to deal with an uncertain world, even though we know from personal experience that such an exercise is far from stable. In other words, by definition, if you make a prediction of any kind, you are taking career risk. To deal with this risk, economists, for example, take pains to be conservative in their estimates until they see the other guy’s estimates. One can see how economists cluster together in their estimates and, even when the economy goes off the cliff, they will merely lower their estimates by 30 basis points each month, instead of whacking them down by 300 in month one. That way, they can see what the other guy is doing. So they go down 30, look around, go down another 30, and so on.
市场正因为这种以保住饭碗为目标的博弈策略而变得极度低效。但股市中存在一个核心真相:在一切表象之下,有一种经济现实在起作用。围绕重置成本存在套利空间。如果你能在市场上用新建一家聚乙烯工厂一半的价格买到一家现成的,你可以想象有多少人会再去建新厂。所有人都会停止建厂,转而通过股市收购竞争对手的工厂。聚乙烯产能会耗尽,价格会不断上涨,直到你精打细算后发现,可以新建一座工厂,还能留出安全边际并获得可观回报,这个周期才算结束。反过来,如果你铺设光纤电缆,而市场对其的估值是你安装成本的三倍,那你就会卖掉一些股份,再去铺设更多电缆,直到你被光纤电缆淹没——这正是 2001 年和 2002 年发生的事情。
And the market is gloriously inefficient because of this type of career-protecting gamesmanship. But there is a central truth to the stock market: underneath it all, there is an economic reality. There is arbitrage around the replacement cost. If you can buy a polyethylene plant in the market for half the price of building one, you can imagine how many people will build one. Everybody stops building and buys their competitors’ plants via the stock market. You run out of polyethylene capacity, the price eventually rises and rises until you sharpen your pencil and find you can build a new plant, with a safety margin and a decent return, and the cycle ends. Conversely, if you can lay fiber-optic cable and have it valued in the marketplace at three times the price that it cost you to install, then you will sell a few shares and lay some more cable, until you drown in fiber-optic cable, which is exactly what happened in 2001 and 2002.
问题在于,这些周期有的跑得特别快,有的却特别慢。而客户的耐心时长正好是三年整。一旦超过这个期限,你就危险了,而有些周期确实会超过三年。你会因此流失大量业务,就像 1998 年和 1999 年的 GMO 那样。这种时间上的不确定性,正是职业生涯和企业风险的根本来源。这其实就是凯恩斯第 12 章的精要概括,只不过没那么文雅。图表 1 还把整个过程分成凯恩斯部分和格雷厄姆-多德部分。再来说说外推法。外推法是理解市场的另一种方式。图表 2(债券市场与通货膨胀)是我最喜欢的外推示例图。它显示了长期国债是如何传统地把短期通胀率外推到遥远未来的。你可以看到,通胀率在 1982 年达到了 13% 的峰值。
The problem is that some of these cycles happen really fast, and some happen very slowly. And the patience of the client is three point zero zero years. If you go over that time limit, you are imperiled, and some of these cycles do indeed exceed it. You lose scads of business, as GMO did in 1998 and 1999. This timing uncertainty is what creates career and business risk. This is really a synopsis of Keynes’ Chapter 12 without the elegance. Exhibit 1 also divides the process into the Keynes part and the Graham and Dodd part. Another word about extrapolation. Extrapolation is another way of understanding the market. Exhibit 2 (Bond Market and Inflation) is my favorite extrapolation exhibit. It shows how the long Government Bond has traditionally extrapolated the short-term inflation rate into the distant future. You can see how inflation peaked at 13% in 1982.
现在,通胀率到了 13%,你会预期短期国债收益率在 15% 左右。确实如此。那 30 年期国债呢?收益率到了 16%。30 年期国债把通胀率的一个极端点位(13%)—— 这个数字总共就持续了大约 20 分钟 —— 硬是外推到了 30 年!当然,还加了 3% 的实际回报率。沃尔克当时正咬牙切齿地发誓要压垮通胀,哪怕是死也要做到,可市场仍然把 13% 外推了 30 年。然后,到了 2003 年,通胀率降到了 2%,30 年期国债收益率也降到了 5%。又是 2% 通胀率加上 3 个点的实际回报。哦,这次通胀要维持在 2% 水平 30 年了?这是极其天真的外推法,不是吗?而且,从某种意义上说,股市的表现更糟糕。图表 3 显示了市盈率的起伏波动。在一个有效市场中,它本应稳定得多。
Now, with inflation at 13%, you would expect the T-bill to yield around 15%. It did. How about the 30-year Bond? It yielded 16%. The 30-year Bond took an extreme point in inflation (13%) that existed for all of about 20 minutes and extrapolated it for 30 years! Of course, with an added 3% for a real return. Volcker was snorting flames that he was going to crush inflation or die in the attempt, and they still extrapolated 13% for 30 years. Then, in 2003, inflation was down to 2% and the 30-year Bond was down to 5%. 2% inflation plus three points of real return again. Oh, it was going to stay at 2% for 30 years this time? It’s incredibly naïve extrapolation, isn’t it? And, in a way, the stock market is even worse. Exhibit 3 shows the ebb and flow of P/E. In an efficient world, it would be far more stable.

GMO 的洛(Lo)来自麻省理工学院,他说市场有两个阶段:大部分时间它是有效的,然后——砰!——它会有一段时间变得疯狂。这完全不是我看待市场的方式。每次市场越过公允价值时,它是有效的。每五六年或七年里,它有效几秒钟。其余时间,它要么飙升要么暴跌,是无效的。
现在,市场应该等于重置成本,这意味着利润率和市盈率之间的相关性应该是 -1。或者用更简单的话说,如果整个经济拥有极高的利润率,考虑到资本主义的本质,你会希望用低市盈率去乘它,因为你知道高回报会吸引竞争、更多资本,并压低回报(反过来在低端也是这样)。但实际情况是什么呢?我们的研究表明,它们之间的相关性不是 -1,而是 +0.32。市场连符号都搞不对!高利润率对应高市盈率,反过来也一样,而且在峰值和谷底时相关性远高于 +0.32。在 1929 年的峰值,我们同时拥有创纪录的利润率和创纪录的市盈率。1965 年,又出现了创纪录的利润率和创纪录的市盈率(21 倍)。现在想想 2000 年。报表利润率创下新高,而我们决定用 35 倍的市盈率去乘它——这个水平远高于之前任何时期。完全相反的是,1982 年我们的利润只有正常水平的一半,市盈率也只有正常水平的一半(8 倍)。我的意思是,饶了我吧。在低谷时,我们只拿到接近重置成本的三分之一,而在 2000 年的高点,接近重置成本的三倍。这种双重计算,对我来说,是市场波动的主要驱动力,而且基本上毫无道理。一旦利润率开始下滑,投资者会环顾四周的竞争者,发现所有人都在搭顺风车,结果我们就得到了高估的价格。这是一个经典的合成谬误。对于一家公司来说,拥有超常的利润率理应获得相对于竞争对手的溢价市盈率。但对于整个市场来说,其利润率有着美妙地向均值回归的特性,情况恰恰相反。这个看似矛盾的现象似乎持续地愚弄着市场。

This is not at all how I see it. Every time the market crosses fair value, it’s efficient. For a few seconds every five or six or seven years, it’s efficient. The rest of the time, it is spiking up or spiking down, and is inefficient. Now, the market should equal replacement cost, which means the correlation between profit margins and P/Es should be −1. Or, putting it in simpler terms, if you had a huge profit margin for the whole economy, capitalism being what it is, you would want to multiply it by a low P/E because you know high returns will suck in competition, more capital, and bid down the returns (conversely at the low end). But what actually happens? Instead of having a correlation of −1, our research shows it has a correlation of +.32. The market can’t even get the sign right! High profit margins receive high P/Es and vice versa, and the correlation is much greater than +.32 at the peaks and the troughs. Right at the peak in 1929, we had record profit margins and record P/Es. In 1965, there were new record profit margins and record P/Es (21 times). Now, think about 2000. We had a new high in stated profit margins and decided to multiply it by 35 times earnings, a level so much higher than anything that had preceded it. In complete contrast, in 1982 we had half-normal profits times half-normal P/Es (8 times). I mean, give me a break. We were getting nearly one-third of replacement cost at the low, and almost three times replacement cost at the high in 2000. This double counting is, for me, the great driver of market volatility and, basically, it makes no sense. Once profit margins start to roll, investors look around at the competition, who are all going along for the ride, and we get overpricing as a result. It is a classic fallacy of composition. For an individual company, having an exceptional profit margin deserves a premium P/E against its competitors. But for the market as a whole, for which profit margins are beautifully mean reverting, it is exactly the reverse. This apparent paradox seems to fool the market persistently.
我们刚才探讨的那一系列过程——职业风险、从众追捧、趋势外推、以及重复计价——允许甚至助长了资产类别泡沫的形成。但资产泡沫并非凭空随机而生。它们往往基于某些真实的东西——一些新颖、令人兴奋或印象深刻的事物,比如异常强劲的销售额、GDP 或利润,这些足以让想象力自由驰骋。随后,当市场启动并加速运行时,从众追捧和重复计价(以及其他因素)便会促成一轮远超基本面所支撑的上行螺旋。要形成一个泡沫,仅需另一个条件,那就是充裕的货币供给。当你同时具备这两个因素——一个强劲、最好是近乎完美的经济,加上充裕的货币——几乎必然会有泡沫形成。
The process we’ve been looking at – career risk, herding momentum, extrapolation, and double counting – allows, even facilitates, the process of asset class bubbles forming. But asset bubbles don’t spring out of the ground entirely randomly. They usually get started based on something real – something new and exciting or impressive, like unusually strong sales, GDP, or profits, which allow the imagination to take flight. Then, when the market is off and running, momentum and double counting (among other factors) allow for an upward spiral far above that justified by the fundamentals. There is only one other requirement for a bubble to form, and that is a generous supply of money. When you have these two factors – a strong, ideally nearly perfect economy and generous money – you are nearly certain to have a bubble form.
不过,预测泡沫可不是件容易的事。这活儿费力不讨好,还得承担预测不准带来的职业风险。但判断泡沫会不会破裂,就完全是另一码事了。泡沫的破裂是确定无疑的,或者说基本确定无疑,而这种"预言"工作对我来说要顺心得多。但凡有点本事的价值型基金经理,都能判断出什么时候出现了大泡沫。刻意不去利用泡沫,在我看来,那就是智力上的懒惰,或者纯粹是胆小鬼的行为——这也是那些原本头脑清醒、勇气可嘉的本杰明·格雷厄姆与戴维·多德信徒身上常见的通病。
Forecasting bubbles, though, is problematic. It is hard work and involves predictions and career risk. Whether bubbles will break, though, is an entirely different matter. Their breaking is certain or very nearly certain, and that sort of prognosticating is much more appealing to me as a job description. Any value manager worth his salt can measure when there is a large bubble. To avoid exploiting bubbles is intellectual laziness or pure chickenry and is a common failing, in my opinion, in otherwise sensible and suitably brave Graham and Doddites.
我毫不掩饰地崇拜泡沫。最早期的泡沫之一——著名的南海泡沫——见图表 4。它很美,不是吗?形态完美。顺便一提,我们研究过的所有泡沫,平均来看,上涨要三年半,下跌要三年。关于这点我只想说两句:34 个泡沫,对于效率市场信奉者来说,这个数字并不令人惊讶。随机情况下,人们预期会出现一些异常值。所以我们有了 34 个不错的小样本可供研究。但问题在于:按效率市场的观点,当泡沫形成时,它被视为一种范式转变——某一资产类别或行业的长期价值发生了真正的转变。如果那才是原因——一种根本性的变化,而非我们描述的那套基于行为因素的东西——那么在效率世界里,这些峰值之后会发生什么?那还用说,价格会沿着无数种飞行轨迹随意游走,其中一半向上、一半向下,我想还有一两个近乎横盘。而我们那个不配合的真实世界到底发生了什么?所有泡沫都回归到了原始趋势——即泡沫形成之前就已存在的趋势。以美国房地产泡沫为例。根据其先前的价格和波动历史,这是一个三西格玛、百年一遇的泡沫。它之后出现一场同样完美的、形态对等的崩盘,概率有多大?自然是百分之一。所以一个三西格玛的泡沫应该随机形成,每 100×100 年,也就是每一万年崩溃一次,如钟表般精确。而更常见的两西格玛、四十年完成的泡沫,则每 1600 年发生一次。然而,我们实际观察到的 34 个完整的泡沫周期,全部都是如此——按随机概率,这足以让好几个宇宙冷却下来,而泡沫还不会出现一次。
I unabashedly worship bubbles. One of the very early ones – the famous South Sea Bubble – is shown in Exhibit 4. It’s beautiful, isn’t it? The shape is perfect. The average of all of the bubbles we have studied, by the way, is that they go up in three and a half years, and down in three. Let me just say a word about that: 34 bubbles is not a surprising number to an efficient market believer. Randomly, one would expect some outliers. So, we have a nice little body of 34 to study. But here’s the problem: in the efficient market view, when a bubble forms, it is seen as a paradigm shift – a genuine shift in the very long-term value of an asset class or an industry. If that were the reason – a fundamental change, not the package of basically behavioral factors we’ve described – then what would happen following these peaks in an efficient world? Why, the prices would wander off on an infinite variety of flight paths, half of them upwards and half downwards with, I suppose, one or two nearly sideways. What happens exactly in our inconvenient real world? All of them go back to the original trend, the trend that was in place before the bubble formed. Take the U.S. housing bubble, for example. Based on its previous history of price and volatility, it was a three-sigma, 100-year bubble. What were the odds that it would be followed by a beautiful-looking bust of equal and opposite form? Why, 1 in 100, of course. So a three-sigma bubble should form randomly and burst every 100 x 100 years, or every 10,000 years, like clockwork. And the more frequent two-sigma, 40-year completed bubbles would occur every 1,600 years. Yet we have had 34 out of 34 complete bubble cycles, which would allow several universes to grow cold before occurring randomly.

这是我对理性预期和有效市场假说充满热情的原因之一。(是的,我知道我们仍在等待英国和澳大利亚房市的异常泡沫破裂。总有一天它们会破的——即便有浮动利率抵押贷款在行情不好时靠降息来托底。我最近遇到一个英国人,他支付的利率只有 0.75%。没开玩笑。)

Even with their variable rate mortgages to support them in bad times as the rates drop. I recently met a Brit paying ¾ of 1%. No kidding.)
附录 4 还提到了艾萨克·牛顿,这事也许是真的,但无论如何都是个精彩的故事。牛顿运气极好,早早地就参与了南海泡沫。他做了一笔相当不错的投资,迅速大赚了一笔,这对他意义重大,金额也足够可观。随后他退出了,却遭遇了投资中最痛苦的经历:看着身边所有朋友都赚得令人艳羡。他沉不住气了,重新杀回市场,而且为了弥补错失的时间,投入了多得多的资金(其中一部分还是借来的),正好赶上了泡沫破裂的暴跌,最终亏得血本无归。据说他曾说过类似这样的话:“我能计算天体的运行,却无法揣摩人类的疯狂。”
Exhibit 4 also tells you a little bit about Isaac Newton, which may be true and, in any case, is a great story. Newton had the great good luck to get into the South Sea Bubble early. He made a really decent investment and a very quick killing, which mattered to him. It was enough to count. He then got out, and suffered the most painful experience that can happen in investing: he watched all of his friends getting disgustingly rich. He lost his cool and got back in, but to make up for lost time, he got back in with a whole lot more (some of it borrowed), nicely caught the decline, and was totally wiped out. And he is reported to have said something like, “I can calculate the movement of heavenly bodies but not the madness of men.”
附件 5 展示了 2000 年以来的六次泡沫。你能看到它们有多完美。我最中意的不是纳斯达克——尽管它在三年内涨了 2.5 倍,又在两年半内跌回原点——而是德国的“新市场”(Neuer Markt),它在三年内暴涨 12 倍,随后在两年半里把每一分钱都跌光了。那可真令人叹为观止。它甚至比南海泡沫还厉害。无论我们英国人能做什么,德国人都能做得更好……
Exhibit 5 shows six bubbles from 2000. You can see how perfect they are. My favorite is not the NASDAQ, even though it went up two and a half times in three years and down all the way in two and a half years. My favorite is the Neuer Markt in Germany, which went up twelve times in three years, and lost every penny of it in two and a half years. That is pretty impressive. It’s even better than the South Sea Bubble. Whatever we English could do, the Germans could do better...
图 6 展示的是美国房地产泡沫。我们展示这张图(我发誓,千真万确)是在陡峭爬升的半山腰。它之所以让我们印象深刻,一个原因是美国历史上从未出现过房地产泡沫,正如罗伯特·希勒指出的,数据也清楚地表明了这一点。过去,芝加哥会繁荣,但佛罗里达会萧条。多样性总能起到缓冲作用。这需要格林斯潘,需要零利率,需要对抵押贷款工具的惊人重新包装,需要人们恳求别人从房子里提取权益,再在佛罗里达买另一套房子。(我们有邻居最后手里攥了三套……)这注定要崩,但就在顶点(2006 年 10 月),伯南克说:“美国房地产市场在很大程度上反映了一个强劲的美国经济……美国房地产市场从未下跌过。”(当然,言下之意就是它永远不会跌。)他到底在想什么?!这是《致投资委员会的信 XVII》,2011 年 1 月 GMO 图 5 2000 年完美泡沫 纳斯达克互联网指数 300 800 250 3 年 2.5 年 3 年 2.5 年
Exhibit 6 is the U.S. housing bubble. We were showing this exhibit (cross my heart and hope to die) half way up that steep ascent. One reason we were so impressed with it is that there had never been a housing bubble in American history, as Robert Shiller pointed out and was clear in the data. Previously, Chicago would boom, but Florida would bust. There was always enough diversification. It took Greenspan. It took zero interest rates. It took an amazing repackaging of mortgage instruments. It took people begging other people to take equity out of their houses to buy another one down in Florida. (We had neighbors who ended up with three…) It was doomed, but, right at the peak (October 2006), Bernanke said, “The U.S. housing market largely reflects a strong U.S. economy ... the U.S. housing market has never declined.” (Meaning, of course, that it never would.) What the hell was he thinking?!

Surrounded by statisticians, he could not see a three-sigma housing bubble in a market that previously had never had one lousy bubble at all. I say it is akin to the Chicago story where two economics professors cross the quadrangle, pass a $10 bill on the ground, and don’t pick it up because they know, in an efficient world, it wouldn’t be there since it would already have been picked up. Bernanke couldn’t see a housing bubble because he knew we don’t have housing bubbles – bubbles don’t exist in big asset classes because the market is efficient. As Kindleberger, the well-regarded economics historian said, the efficient market people (like Fama, French, Cochrane, Lucas, and Malkiel) “ignore the data in defense of a theory.”
我们常列的十二个著名泡沫列在图 7 中。第一行展示了不同股市:1929 年、1965 年、日本以及 2000 年。关于 2000 年,可以看到,直到 2008 年,美国市场才回归趋势线。它的形态很有意思,中间包含一段持续数年的强劲上涨。我很欣慰地说,在 2004 年和 2005 年,我曾将市场的上涨描述为“历史上最大的傻瓜式反弹”,所以当它在 2009 年破灭并彻底完成泡沫周期、甚至变本加厉时(如图 8 所示),我大大松了口气。所以,说到底,艾伦大叔和他的利率神操作只是推迟了不可避免的结果。也许这次历史会重演。大规模救助资金的确阻止了市场跌到本应达到的低位——若按危机严重程度,合理跌幅本该如此。根据历史经验,标普 500 指数合适的跌幅本应跌到 400 多点或 500 多点。
The twelve famous bubbles we always list are shown in Exhibit 7. The top row shows various stock markets: 1929, 1965, Japan, and 2000. Regarding 2000, we can see that, until 2008, the U.S. market did not get to trend. It has an interesting shape, including a wonderful several-year rally. I am pleased to say that in 2004 and 2005, I described the market’s ascent as “the greatest sucker rally in history,” so I was very relieved that it wiped out and completed the bubble cycle by bursting in 2009, with interest, as shown in Exhibit 8. So, in the end, Uncle Alan and his interest rate heroics only postponed the inevitable. Perhaps it will be the same again. The surge of bailout money certainly prevented the market from going as low this time as would have been justified by the severity of the crisis. Based on history, an appropriate decline would have been into the 400s or 500s on the S&P.
股市板块也从未失手地涌出过泡沫——成长股、价值股、日本成长股,等等。事实上,它们一向非常可靠。我认为,忽视泡沫就是避开最佳、最简单的赚钱方式之一。在巴特马奇,我们 1972‑1973 年投资了小盘价值股,因为我们绘制了一张回溯至 1925 年的小盘股相对表现涨落图,从中看清了小盘股这个大周期。我们看到了图表 7 《所有泡沫终将破裂……除了股票》。

Stock market sectors have also bubbled unfailingly – growth stocks, value stocks, Japanese growth stocks, etc. In fact, they’ve been very dependable. To ignore them, I believe, is to avoid one of the best, easiest ways of making money. At Batterymarch we invested in small cap value in 1972-73 because we had created a chart of the ebb and flow of the relative performance of small cap that went back to 1925, and we could see this big cycle of small caps.

同样的规律随着价值潮起潮落。我们赚了一大笔钱:仅仅八年时间,Batterymarch 就从 1974 年底管理的 4500 万美元,到 1982 年成长为业内最大(即便不是最大)的独立咨询公司。这很大程度上没靠我帮忙,因为我 1977 年就离开了,不过我倒留下了一个我史上最棒的主意——小盘价值股。小盘价值股不光赢了;它赢了超过 200 个百分点。小盘股本身赢了超过 100 个百分点(+322% 对比 +204%)。延续了这一传统的 Batterymarch 和 GMO,赢了超过 100 个百分点。但我们没跟上小盘价值股的步伐,这个教训让我终生难忘:我们打出了最惊天动地的本垒打,却竟然没跑赢小盘价值股基准。(原因之一是我们在挑选质量更高的股票——真正的幸存者。从 1974 年的底部算起,指数被一大群小微型股票加足了马力,这些股票售价比如每股 1⅞ 美元。要是世界再多坏两个季度,它们就会破产完蛋,可结果在市场转向后六个月内,它们的价格就翻了两番。)在这种情况下,选对板块比选股更强大。这类主题非常、非常难以战胜。

Source: GMO As of 10/10/08 same ebbing and flowing with value. We made a ton of dough: in just eight years, Batterymarch went from $45 million under management in late 1974 to being one of the largest, if not the largest, independent counseling firm by 1982. It did so mostly without my help, since I left in 1977, although I did bequeath my best-ever idea – small cap value. Small cap value didn’t merely win; it won by over 200 percentage points. Small cap itself won by over 100 points (+322% versus +204%). Batterymarch and GMO, which continued that tradition, won by over 100 points. But we didn’t keep up with small cap value, and that has been a lesson that has echoed through my life: we hit the most mammoth of home runs, and yet couldn’t beat the small cap value benchmark. (One reason was that we were picking higher quality stocks – the real survivors. From its bottom in 1974, the index was supercharged by a small army of tiny stocks selling at, say, $1⅞ a share. These stocks, which were ticketed for bankruptcy if the world stayed bad for two more quarters, instead quadrupled in price in the six months following the market turn.) Picking the right sector was, in that case, more powerful than individual stock picking. Such themes are very, very hard to beat.
最后我要强调,在我看来,针对重大周期的涨跌起伏做出应对,把重注留到极端边缘时刻,绝对是大资金增加价值、降低风险的最佳方式。相比之下,当“泡沫快车”朝你呼啸而来时,你站在铁轨上等着被撞,以此表明你对宏观概念的蔑视、对自己选股核心技能的盲目执着——那实在是痛苦至极。真正的大泡沫,连最优秀的格雷厄姆-多德式投资组合也会被冲走一大块。忽视它们绝非明智之举。
Let me end by emphasizing that responding to the ebbs and flows of major cycles and saving your big bets for the outlying extremes is, in my opinion, easily the best way for a large pool of money to add value and reduce risk. In comparison, waiting on the railroad tracks as the “Bubble Express” comes barreling toward you is a very painful way to show your disdain for macro concepts and a blind devotion to your central skill of stock picking. The really major bubbles will wash away big slices of even the best Graham and Dodd portfolios. Ignoring them is not a good idea.
