GMO 季度信函 2004 年 10 月 杰里米·格兰瑟姆,董事长 倒计时继续 & 致投资委员会的信函 I 引言

自 1932 年以来,总统选举年表现最强的季度是第四季度,我仍然认为,在今年第四季度,股市出现一个像样的表现,概率超过一半,随后才进入总统周期的第一和第二年困难期。与此同时,第三季度非常隐蔽。似乎什么都没发生,但到季度末,已经出现了重大转变,多数转变都有利于我们。我们今年最大的押注——新兴市场和小盘国际股票,以及较小程度的 REITs(房地产投资信托基金),相对于标普 500 指数——在第一季度大获全胜,却在第二季度遭受重创。在刚过去的这个季度,新兴市场和 REITs 指数均跑赢标普 500 指数超过 10%,小盘国际指数相对于标普 500 指数的年初至今领先优势也略微扩大至 +8%。事实上,GMO 全球平衡资产配置策略中的所有 17 个成分(从常规国内债券和 TIPS(通胀保值债券)到 EAFE(欧洲、澳洲和远东指数)股票)在季度内都跑赢了标普 500 指数,年初至今也是如此,除了我们新的质量策略——最不凑巧的是,它在季度的最后一天因默克公司意外撤回 Vioxx(万络)而落后。

GMO 短期预测的准确性

进入今年时,我们曾预测外国和新兴市场股票将跑赢,并且作为总统周期的信奉者,我们还预计会出现一个典型的低波动年份,美国股票收益相当不错。好吧,我们确实迎来了一个波动极低的标普 500 年份,其波动率大约只有正常水平的一半,几乎恰好等于总统周期所有第四年的异常低平均水平。外国和新兴市场股票也如预测那样跑赢了美国股票,但美国股票市场本身的涨幅尚未达到我们在去年第四季度信函中预测的 +11%。不过,今年尚未结束,而且,我认为反直觉的是,总统选举年最强季度是第四季度,我仍然认为,在今年第四季度,股市出现一个像样的表现,概率超过一半。

2004 年的傲慢奖

在去年的合理预测中,有一个关于新兴市场股票的预测显得格外激进。由于它在相对平淡的一年里上涨了 13%(截至 2004 年 10 月 4 日),而且可能还会继续上涨,所以单纯看好新兴市场本已效果不错,但当时却拿出了最火爆的措辞:“在没有中国危机的情况下,新兴市场可能直接上涨 30%、40%,甚至更多。” 我确实相信,而且至今仍相信,新兴市场最终会跑赢标普 500 指数 30% 或 40%,但“直接上涨”或任何“直接”的说法,完全忽视了市场的一个核心真理:基于价值的谨慎估计最终会获胜,这通常会善待你,但时机选择通常会要你的命。

中期预测的准确性

表 1 重现了我们实际在 2000 年 3 月(即 4 年半前)市场顶部时所做的 10 年期资产类别预测。(我们目前的 7 年期格式是在一年后开始的。)令我惊讶的是,尽管标普 500 指数当时看起来很难看,但许多资产类别在当时却显得相当有吸引力。表 1 是对 2000 年 3 月时 12 个资产类别按估计吸引力进行的排名,其中 10 个来自表 1,排除了现金和林业,另外两个来自我们月度预测通常的第二部分——重要的美国小盘价值股和大盘价值股类别。该表格将我们的预测与实际结果进行了比较。它远非一个完美的排名,但右侧显示的是原始估计中最佳四个、中间四个和最差四个投资组合的平均实现收益率。它们的排名顺序无疑是正确的,每个区间的平均误差小得出乎意料,一些受青睐的资产表现优异,弥补了另一些表现不佳的资产。GMO 相对于基准的平均超额收益为

GMO Quarterly Letter October 2004 Jeremy Grantham, Chairman The Countdown Continues & Letters to the Investment Committee I Introduction strongest quarter of the election year since 1932 has been We’re down to 3 little months, probably quite good ones the fourth quarter, and I still think a decent fourth quarter before we reach the difficult years one and two of the this year for equity markets is a better than even bet. Presidential Cycle. In the meantime, the third quarter was very stealthy. Nothing seemed to be happening, and The Hubris Award for 2004 yet, by the end, there had been important shifts, most of Amid the reasonable predictions from last year, the one them happily to our advantage. Our biggest bets this year for emerging markets equity stands out as remarkably on emerging and small cap international equities, and to a aggressive. Since it is up 13% (as of 10/4/04) in a flattish lesser extent REITs, all relative to the S&P, had won year, and may do some more yet, a simple preference for handsomely in the first quarter and had been hammered emerging would have worked out fine, but the hottest in the second. In this recent quarter, the emerging and language yet was wheeled out. “Without a Chinese crisis, REIT indices both beat the S&P by over 10%, and the emerging could go straight up 30%, 40%, or more.” small cap international index slightly increased its year- Well I did and still do believe that emerging will beat the to-date lead over the S&P to +8%. In fact, all 17 S&P from then by 30 or 40% eventually, but “straight components in GMO’s Global Balanced Asset Allocation up” or straight anything is to completely ignore one of the Strategy (from regular domestic bonds and TIPS to EAFE central market truths: careful estimates based on value equities) beat the S&P in the quarter, and also year-to- eventually winning will usually treat you well, but timing date, except for our new Quality Strategy which, will usually try to kill you. unkindest cut of all, fell behind on the last day of the quarter because of Merck’s unexpected withdrawal of Accuracy of Intermediate-Term Forecasts Vioxx. In a choppy year, the steadiest trends have been Exhibit 1 reproduces our actual 10-year asset class in the underperformance of technology stocks, growth forecast done at the top of the market, 4½ years ago in stocks, and highly volatile (or risky) stocks. Each of March 2000. (Our current 7-year format started a year these trends continued in the third quarter later.) What is surprising to me now is how many of the asset classes looked quite attractive then despite the Accuracy of GMO’s Short-Term Forecasts ugliness of the S&P 500. Table 1 is a ranking at March Coming into this year, we had predicted outperformance 2000 by estimated attractiveness of 12 asset classes, 10 of by foreign and emerging equities, and as growing which come from Exhibit 1 with cash and forestry believers in the Presidential Cycle, we had also looked excluded, and two are added from the usual part two of for a typical low volatile year with quite good US equity our monthly forecasts – the important US small cap value gains. Well, we’ve certainly had a wonderfully low and large cap value categories. The table compares our volatile year for the S&P with about half the normal forecasts to the actual results. It is far from a perfect volatility almost exactly equal to the remarkably low ranking, but on the right is the average for the delivered average for all year fours of the Presidential Cycle. returns of the best four original estimates, the middle Foreign and emerging equities also outperformed US four, and the worst four. They are certainly ranked in the equities as predicted, but the US equity market itself is right order, and the average error of each block is not yet up as much as we forecast in last year’s fourth unexpectedly small with outperformance of some quarter letter (+11%). The year however is not yet over favorites offsetting underperformance of others.

GMO 季度通讯——2004 年 10 月 2 GMO 第三季度及年初至今业绩

我们管理的资金中超过 80% 在第三季度跑赢了各自对应的基准指数,年初至今这一比例超过 70%。当季表现强劲的策略包括新兴市场、新兴国家债券、国际价值、国际债券以及美国核心策略。年初至今表现欠佳的是新兴股票(落后约 2%)以及我们几乎所有美国股票组合(除美国核心外),尽管所有落后的组合都控制在 0% 至 -2% 的区间内,而非大幅下跌。美国市场特别起伏不定的一年对我们的动量策略——以及所有人的动量策略——都非常残酷,而我们价值投资的优质倾向也表现得相当反常。我们的价值模型大致与标普 500 指数持平,但远落后于市盈率和市净率等低质量版本的模型。定量策略在今年前 15 个下跌日中输了 14 个,而在前 18 个上涨日中全部获胜——对该策略而言这是一种极为激进的姿态,该策略通常能赢得 62% 的下跌日。好了,在过去 3 个月里,它赢了 60% 的下跌日,还算令人满意,但算不上英雄壮举。GMO 规模最大的发达国家国际定量策略(国际内在价值策略),通常能在令人瞩目的 77% 的下跌日中获胜,在过去 3 个月里,它赢了 62% 的下跌日,这已经呈现空头市场偏向,但显然还不是我们通常的偏向。我们的全球平衡资产配置策略,作为我们资产配置策略的代表,在本季度 65% 的下跌日中跑赢了其基准指数,而正常水平是 80%。GMO,郑重说明,过去在其所有股票组合上都在下跌日中拥有明显的获胜优势,只有新兴股票组合的中性除外。

GMO Quarterly Letter – October 2004 2 GMO Third Quarter and Year-to-Date Performance quantitative strategy, lost 14 of the first 15 down days this Over 80% of our money under management beat its year and won the first 18 out of 18 up days – a uniquely respective benchmark for the third quarter, and over 70% aggressive posture for this strategy, which typically wins won year-to-date. Strong outperformers for the quarter 62% of down days. Well, over the last 3 months, it has were our emerging markets and emerging country debt won 60% of down days; perfectly satisfactory, but not yet strategies, international value, international bonds, and heroic. GMO’s largest developed country international US core. Underperforming for the year are emerging quant strategy (International Intrinsic Value), which equities, behind by about 2%, and almost all our US typically wins a remarkable 77% of down days, has won equity portfolios, other than US core, although all the 62% of them in the last 3 months, already a bear market underperformers are contained in the 0% to -2% range, bias, but clearly not yet our normal bias. Our Global rather than a severe decline. The particularly choppy year Balanced Asset Allocation Strategy, a proxy for our asset in the US has been brutal for our momentum streams – allocation strategy, has beaten its benchmark on 65% of and everyone else’s – and our quality bias to value has the down days in the quarter compared to a normal 80%. been quite strongly perverse. Our value models are about GMO, for the record, has had a distinct winning edge on level with the S&P, but far behind lower quality versions the downside in the past for all its equity portfolios, like price/earnings and price/book. except emerging equity, which is neutral.

关于“品质”与“贝塔”的简短讨论

若以更传统的定性方法衡量品质,最后这一点——即今年高品质股的欠佳表现——对我们而言很有趣,因为它与低波动或低贝塔股票的出色表现形成了背离。包括我们在内的大多数人,往往倾向于认为品质——从根本上定义为低负债、高利润率及高利润率稳定性——通常具有与低贝塔股票相同的投资组合优缺点,但事实证明二者之间存在引人注目的差异。今年,我们已通过将小盘股的超配比例从超过 +8% 降至仅 +4.2%,降低了国际内在价值策略中的风险。对高品质股(前 25%)的押注已从 -3 个百分点变为 +9,而特别危险的高波动股(前 25%)则从 +6 个百分点变为 -5。在美国核心策略中,我们极为异常的 17% 超配比例……

A Short Digression on ‘Quality’ and ‘Beta’ Measured in more traditional qualitative ways, we have This last point – the underperformance this year of high reduced our risk in the International Intrinsic Value quality – is interesting to us as it represents a divergence Strategy this year by lowering our overweight in small from the outperformance of low volatile or low beta cap to just +4.2% from over +8%. The bet on high stocks. Most of the world, including us, have tended to quality (best 25%) has moved from -3 percentage points think of quality – fundamentally defined as low debt, to +9, and particularly dangerous high volatile stocks high profit margins, and high margin stability – as having (highest 25%) have moved from +6 percentage points to generally the same portfolio virtues and vices as low beta, -5. In U.S. Core, our highly unusual 17% overweighting but they turn out to be interestingly different.

首先,在去年波动性最高的 25% 股票中,按我们的高质量定义、市值排名前 25% 的那部分,到今年已经完全消失了。总体而言,这类股票年初至今下跌了 4.5%,而波动性最低的 25% 股票(包括新兴市场和英国股票策略)则上涨了 5%,两者均相对于市场而言。更令人惊讶的是,在两者相对表现上,长期相关性出现了一股稳定但累计幅度很大的趋势——质量因子走强,高波动因子则走向负 6% 的区域!我们目前正在研究这个谜题的内因和外因,时间跨度为过去 9 个月。研究结果可能对如何在未来危险的两年中最好地保护投资组合产生重要影响。我们将在客户会议上介绍我们在这方面的早期工作,但初步研究显示,低贝塔和低波动性在下跌行情中的帮助比我们预期的更大,而高质量因子的帮助则没那么大。敬请期待。

For starters, in the 25% highest volatile stocks that existed last year the best 25% by market cap on our high quality definition and into this year has disappeared completely. In all is down 4½% year-to-date while the least volatile 25% is equity strategies, including emerging and UK equity, up 5%, both relative to the market. More surprisingly, the there has been a steady, but cumulatively large move to long-term correlation in their relative performance is increased quality and away from high volatility over the negative 6%! We are currently researching the ins and last 9 months. outs of this puzzle. The results could bear quite importantly on how to best protect portfolios in the next The Bull and Bear Cases for the US Equity Market 2 dangerous years. We will cover our early work on this I have to reluctantly admit that the current bear case at our client conference, but our initial work suggests that seems complicated and relatively sophisticated or historical low beta and low volatility is even more helpful “intellectual” unlike March 2000 when it seemed very, in a decline than we expected and high quality less so. very simple: the market was obviously overpriced on Stay tuned. every reasonable measure.

彼时看涨的论据,反过来说,可以(无疑带着一些 GMO 的负面解读)归纳为两大阵营。其一,阿比·科恩等人所言:“经济、生产力与利润状况良好,因此市场也会安然无恙。”其二,更为荒谬的“道指 36000 点”式论点:“股票风险低于债券,因此应当以低于债券的总回报率来定价”——这实际上意味着,鉴于当时债券利率很低,市场将以重置成本的四倍来交易!

The bull arguments then, in contrast, could be summarized (no doubt with some GMO Digs In negative spin) as falling into two camps. First, Abby As mentioned in several quarterlies, I was hoping for a Cohen, et al.: “the economy, productivity, and profits are quiet year with some market gains to buy us time to fine so the market will be fine.” Second, the more reposition carefully to more conservative portfolios. We ludicrous Dow 36000 type of argument: “stocks are less could still use a few more months, and as mentioned, I do risky than bonds and therefore should sell at a lower total expect the fourth quarter to be up, but we have already return than bonds,” which meant, for the record, since covered some considerable ground in making our bond rates were low, that the market would sell at four portfolios more conservative. times replacement cost!

与此相反,当前的多头论调看似直截了当、引人入胜且易于理解。俗话说“实践是检验真理的唯一标准”,那么我们的策略近期表现与年初相比究竟如何?首先,作为旗舰策略的美国核心策略,由于两年来的强劲盈利,盈利已追赶上近期持平的市场,将市盈率拉低至 18.5 倍——而 18.5 倍的市盈率在当前高于平均水平的利润率、低利率、低通胀以及明年 GNP 增长预期相当强劲(共识预测为 +3.5%,达到或超过长期趋势)的背景下是合理的。全球增长预计也将成为过去 20 年来的最高水平之一。

遗憾的是,如果这就是多头论调的全部依据,那么它在理论和历史上都是站不住脚的。

Now, in contrast, the current bull case seems straightforward, appealing, and easily The best proof of the pudding is in the eating, so how understood. The bull case is that due to very strong have our strategies performed recently compared to earnings for 2 years, the earnings have caught up with a earlier in the year? To start with, U.S. Core, our flagship recently flat market to bring the p/e multiple down to 3 Quarterly Letter – October 2004 GMO 18½, and a multiple of 18½ is reasonable given the The Nightmare for Asset Allocators: What on Earth current above average profit margins, low interest rates, Can We Do to Prevent Losses? low inflation, and quite strong outlook for next year’s GNP growth, for which the consensus is +3½%, which is As mentioned in other quarterlies, asset allocators like at or above long-term trend, and global growth is Ben Inker and me have a lot in common with bond expected to be among the highest of the last 20 years managers in that both groups wail and gnash their teeth when their bets win because of lost opportunities, in Unfortunately, if that indeed is the bull case, then it is complete contrast to equity investors, who when wrong both theoretically and historically.

首先,那些在市场大幅上涨中表现良好的投资者,似乎没有注意到平均利润率对未来预测是一个负面因素,也忽略了错失的机会,反而因为利润率的均值回归特性而欢呼雀跃,高喊“哇,我们发财了!”可事情已经发展得如此顺利——鉴于过去四年半我们基于价值导向的资产配置,如今极高的利润率在历史上通常随后都会导致低于平均水平的股票市场,因为机会看起来极其稀少。(当利润率回落到平均水平时,我纳闷,这种均值回归押注上一次持续了多久?)其结果是,我们的资产配置已经连续经历了 5 个非常轻松的年份:例如,我们的全球平衡资产配置策略,连续跑赢基准的幅度分别为 10%、10%、11%、5% 和 2.5%。第二,国民生产总值(GNP)的增长与股票市场回报之间并无简单易见的关系。我最喜欢举的例子是,1990 年代和 1970 年代——在股市中分别感觉像天堂和地狱——这两个十年的 GNP 增长率以及生产率增长率几乎完全相同。

First, above presented with strong market gains don’t appear to notice average profit margins are a negative for future forecasts, the lost opportunities, but jump up and down with cries of not a positive, since profit margins are dependably mean “Whoopee we’re rich!” Well things have gone so well for reverting and, historically, very high margins, as we have value based asset allocation in the last 4½ years that now, are followed by below average stock markets as opportunities are looking extremely thin. (When, I margins move back down. Second, GNP growth has wonder, did a run of mean reverting bets like this one last unfortunately no easy relationship with stock market occur?) The results of this have been that our asset returns. My favorite example of this is that the decades allocation has had 5 consecutive very easy years: our of the 1990s and the 1970s – which felt like Heaven and Global Balanced Asset Allocation Strategy, for example, Hell, respectively, in the stock market – had almost has outperformed its benchmark in sequence by 10%, identical GNP growth rates, and productivity growth rates 10%, 11%, 5%, and 2½%.

而且,更关键的是,实现这一切的同时风险要低得多。今年的 GNP 增长与明年市场回报率的相关性为 -26%:只有 3 年(1997 年至 1999 年)呈正相关,虽然这 3 年 GNP 增长高于平均,其后市场回报率却低于平均。第三,利率并不影响市场的公允价值——我希望我们一致认为公允价值等于重置成本——而重置成本显然不受利率变动影响。进一步佐证是,90 年的历史记录显示,利率与股市走势之间的相关性几乎为零。

当前资产配置者的噩梦,恰恰是均值回归或价值策略连续 5 年成功的结果。

And, it has done so at much for that matter. This year’s GNP growth is negatively lower risk. The Great Ugly for our allocation was, in correlated with next year’s market returns (-26%) in that contrast, only 3 years (1997 to 1999) and, although our above average GNP this year tends to be followed by asset allocation underperformed badly for these 3 years, below average market returns next year. Thirdly, interest it at least did so with far less risk, I add unpersuasively. rates do not affect the fair value of the market, which I (For the record, why was much lower real risk so hope we agree is equal to replacement cost, and unpersuasive then and why is it still?) replacement cost is obviously not affected by interest rate changes. As further encouragement, the 90-year The nightmare today for asset allocation is exactly the historical record is that the correlations between interest result of these 5 successful years for mean reversion or rates and equity market moves is approximately nil. value.

全球范围内的小盘股和价值股表现耀眼,已经消耗殆尽它们所有的低估——甚至不止。美国房地产投资信托(REITs)已经实现了至少 80% 的、4 年半前从其极大相对廉价中可能预期到的收益。新兴市场股票和新兴市场债务大幅跑赢标普 500 指数,其他所有固定收益类资产也一样,其中我们最爱的通胀保值国债(TIPS)领跑。最接近失败的一个资产类别押注是 EAFE 指数跑赢标普 500 指数,最终 4 年半累计总回报勉强高出 +3%。最后,也是我坚信最重要的一点,你在处理整个市场时,绝不能看未正常化的市盈率。除了要对利润周期进行调整,你还必须考虑到此前申报收益的冲减。理论上,经营利润和净利润应该相等,长期来看非常规借项会被非常规贷项抵消。但在现实中,由于系统性的收益高估,非常规借项存在偏差。

Small stocks and value stocks globally were brilliant and have used up either all their under valuation Finally, and most importantly I believe, you simply or even more than all. US REITs have delivered at least cannot look at unnormalized p/e ratios when dealing with 80% of the benefits that might have been expected from the total market. In addition to adjusting for the profit their enormous relative cheapness 4½ years ago. cycle, you have to allow for write-downs of prior claimed Emerging country equity and emerging country debt earnings. In theory, operating income and net income handsomely beat the S&P 500 as did all other fixed should be the same, with unusual debits in the long run income, with our favorite TIPS at the front. The closest being offset by unusual credits. In real life there is a bias to failure of any asset class bet was on EAFE to beat the to unusual debits because of systematic overstatement of S&P 500, limping home by a +3% total over the 4½ earnings.

过去 10 年里,平均每年有……年。同样的赌注——EAFE 指数跑赢标普 500 指数——如今,毫不意外地,仍是迄今为止最好的那个选项,净减记幅度平均为 14%。所以,如今的公允市值应该基于当前经营利润,扣除正常的 14% 减记调整,再额外下调以反映当前异常高的利润率(很可能在未来两年内回归正常)。正常利润率加上 16 倍的正常化或趋势性市盈率,不幸地,对标普 500 指数算出的公允值是 725 点,与标普目前略高于 1100 点的价格相比,令人难堪。

但还有什么有趣的?在我们当前的 7 年预测中,除了新兴市场股票(仅略高于公允价值),每一个股票和固定收益资产类别都被高估了。

因此,我们对基于基准指数的资产配置给出的总结性建议倒很简单:

In the last 10 years, there has been an average years. That same bet – EAFE to beat the S&P 500 – is, of 14% net write-downs. So fair market value today not so coincidentally, by far the best bet remaining. should be based on current operating earnings less the normal 14% downward adjustment for write-offs, and a But what else is interesting? On our current 7-year further downward adjustment to allow for abnormally forecast every equity and fixed income asset class shows high current profit margins that will regress, very as overpriced except for emerging equity, which is just probably in the next 2 years. A normal profit margin about fair value. combined with a normalized or trend line p/e of 16 Our summary advice for asset allocation on a relative to unfortunately produces for the S&P 500 a fair value of benchmark basis is easy enough though: 725, which compares painfully to the S&P’s current price of just over 1100.

当今市场看似合理的简单逻辑——尽量将权益配置转向国际、避开美国,以你的职业风险承受能力为限,新兴市场权重超过发达市场,同时认识到在美国熊市结束前新兴市场可能出现一些令人心惊肉跳的下挫——这种逻辑既极具诱惑力,又极为普遍,因此相当危险。

GMO 季度通讯——2004 年 10 月第 4 页

需要认识到,在下跌年份中,新兴市场可能出现一些令人心脏骤停的时期,这与之前三年和四年形成惊人对比——之前只有五年是下跌的。更糟糕的是,市场的估值水平(在第三年无关紧要,因为昂贵市场无论如何都会上涨)在第一年和第二年至关重要。如果你在第一年和第二年的估值处于所有年份中最差的一半,那么你每年单独亏损的概率会上升到约 70%!

Today’s easy logic of current market • Tilt equities as much towards international and away reasonableness is both very seductive and very common from the US as your career risk account will allow, with and therefore quite dangerous. emerging more overweight than developed, but GMO Quarterly Letter – October 2004 4 recognizing the potential for some heart stopping down in real terms, in startling comparison to years three and periods in emerging before the US bear market is over. four when only 5 years are down. To make matters worse, the value of the market (which does not matter in • Tilt all portfolios (US and international) to quality and year three where expensive markets go up anyway) low volatile stocks, especially those with low debt. Be matters a lot in years one and two. If you are in the worst particularly careful of US small low quality issues half of all years by value in years one and two, your odds whose increased leverage may turn out to be very of a loss rise to about 70% for each year separately! dangerous.

这些相当令人沮丧的概率涵盖了事件的正常情况。其余有待决定的是,现在的风险是否高于正常水平。

第一个叠加的风险是,我们不仅处于自 1925 年以来所有市场中最昂贵的一半时期,而且处于最差的 10% 区间。第二,总统周期主要是一种金融或货币现象,且在不涉及恐怖主义(我认为它无论对错影响都很小)的前提下,我们都能同意,金融体系的风险高于平均水平。公司债务处于其区间的高位,联邦赤字和贸易赤字也是如此,而累计外国债务处于 100 年来的高点,累计家庭债务则创下美国历史新高。房地产市场也明显受到长期宽松且廉价的信贷过度刺激,一旦房价哪怕小幅下跌,就会对消费构成真实威胁。一个重大的潜在风险是,金融资产的价格疲软与住房的价格疲软(两者均由定价过高导致)叠加在一起时,会同时引发某种金融危机,哪怕只是小规模危机。高油价对消费者需求构成的威胁,以及中国经济增长脱轨的可能性(我认为概率很小),是其他几个独立的风险。

综合考虑,我会说,我们正处于被高估的市场光谱中更脆弱的一端,即将进入周期中危险的年份一。但,可能且希望是,我们还有 3 个月合理的时间可以享受。

对于固定收益资产与权益资产,稍微偏向固定收益。大幅偏向固定收益需要对股票大幅下跌的时点抱有极高的信心,因为固定收益本身也中等程度地定价过高,我们对几个股票子类别的 7 年估值预测,加上它们估算的阿尔法值(我们 GMO 的跑赢大盘能力),看起来优于大多数或全部的固定收益类别。

我们基于绝对角度的总结建议虽然更简短,但说出来更令人痛苦:恐慌。随着第三季度全球固定收益、新兴市场股票和债券以及美国 REITs 的反弹,资产从未出现过如此广泛的高估组合。躲在保守型对冲基金里。买入一些外国和新兴市场股票,但要忍受负回报的时期。密切关注多元化投资于包括林业在内的大宗商品,如果你能忍受低回报,就持有一些现金。但无论你做什么,无论你多么绝望,都不要为了追求回报而伸手;不要试图从石头里榨出血来。承担额外风险带来的额外回报非常低,甚至为负,即便 2003 年风险资产经历了美妙反弹。现在是时候降低风险、生存下来,尽可能保全你的资产,以便日后继续战斗。

展望 2005 年和 2006 年

在这种情况下,没有消息就是坏消息,因为我们的预测保持不变——悲观。简单概括一下:自 1932 年以来,总统周期的第一年和第二年有一半多是下跌的,总计 19 次。

季度信函——2004 年 10 月·GMO

GMO 专题·2004 年 10 月

杰里米·格兰瑟姆,主席

致投资委员会的信函

I. 引言

我打算撰写一系列专题,涵盖最重要的投资议题,并以信息充分但非全职专业人士的投资委员会成员的视角来呈现。这封开篇之作,从最根本的地方着手——我认为驱动股票市场运转的基本机制。我们的市场绝不是有效市场假说所描述的那种运转顺畅的机器,而是一台倔强又不可靠的机器,有时运转平稳,有时则会发作。

信函第一号:“回归即均值”

市场中一切重要的东西都是“均值回归的”,或者,如果你愿意,可以说它们围绕一条趋势线游走。价格在一系列“低效因素”的推动下偏离公允价值,并最终被价值的逻辑拉回。在投资者为自己负责的市场中,价格因行为偏差而偏离公允价值。我们天生就不是“经济人”,无法快速高效地处理所有可得信息。相反,我们深受从众心理、过度自信、一厢情愿以及处理多重因素(尤其是涉及概率时)的困难所困扰。在投资者将资金交给专业人士管理的市场中,主要的低效因素变成了职业风险。每个人的最终工作描述都成了“保住饭碗”。降低职业风险优先于最大化客户回报。高效管理职业风险意味着永远不能独自犯错,因此,从众行为(或许出于不同理由)同样成为专业投资的特性。从众行为产生了价格动量,当人们因为别人买入而买入时,价格便进一步偏离公允价值。

价格最终被拉回公允价值,这源于每一资产类别的回报必须与其风险合理挂钩。这是一种持续施加引力作用的力量,将低效的价格拉回正轨,这种力量通常被称为“价值”。在 1982 年或 1945 年那种超级便宜的股市中买入股票的投资者,每年能获得 10% 到 20% 的实际回报,但迟早会有大量竞争者涌入,压低回报率。反之,2000 年面对市盈率 33 倍、隐含年回报率不到 3% 且承担全部股权风险的投资者,最终会心灰意冷并卖出。行为低效与基于价值的低效交织在一起,意味着泡沫会形成,而且所有泡沫都会破灭。

事实上,我们翻阅了能找到的所有关于货币、大宗商品和股票市场的全部数据,发现了 27 个泡沫。与格林斯潘主席不同,我们定义泡沫毫无困难:我们武断地采用两个标准差的事件,这种事件理论上每 40 年随机发生一次。可以预见的是(至少对相信均值回归的人来说),所有 27 个泡沫都破灭了,并且一路跌回到之前的趋势线!同样可以预见的是,当前的泡沫——它在 2000 年 3 月达到最大膨胀程度,是美国历史上最大的泡沫——必须跌破其趋势线,即标普 500 指数的 720 点(目前略高于 1100 点)。如果它做不到这一点,那将是现代史上第一次失败。图 1 展示了各自类别中最著名的 12 个泡沫。除了右上角那个——当前的美国股票泡沫——之外,所有泡沫都已回归趋势。它经历了一场坚实的熊市反弹,就像旁边其他三个泡沫曾经经历的那样,并且很可能在趋势线或低于趋势线处加入其他 27 个泡沫的行列。

泡沫破灭并回归趋势的问题在于,有些泡沫破得快,有些则慢。图 1 也通过突出三个时间节奏明显不同的泡沫,说明了这一点。

因此,在极端情况下,你永远知道会发生什么,但永远不知道什么时候发生。你知道关于遥远未来的一些确定之事,但通常对眼前的未来一无所知。这就是为什么资产类别的价格像飓风中的羽毛——一切都会落到地面,但天知道什么时候。如果时机也可知,那就成了套利机会:如果你知道会发生什么以及何时发生,那么,就像《星际迷航》中的“悖论”一样,它会被提前预期,因此,实际上永远不会发生。

但不知道时机何时到来,却会带来重大的职业风险,而这种风险很难策划规避。好消息是,塑造了商业本质的人类行为风险——它在所有金融市场上都留下印记——永远不会改变,我们始终会拥有这些绝佳的机会来赚钱,同时也会伴随危险的职业处境。如果你比大多数人更聪明,并且想消除职业风险,那就预测其他玩家的动向,在执行上更快、更精明,或者如凯恩斯所说,“抢先一步”。相反,基于价值原则拒绝在泡沫中买入,会显得危险地不合时宜,而当你时机判断错误时——这迟早会不可避免——你将如凯恩斯所言,“得不到多少宽恕”。
