Investment Miscellany
因为我收到了大家对我“互联网泡沫.com”和风险投资备忘录的良好反响,我打算继续写下去。随着时间推移,我积累了一些想法,总忍不住想分享给你们——不是什么大道理,只是一些或许有趣的杂谈。分享这些可能慢慢会变成一种习惯;你们若觉得该继续,不妨告诉我一声。
为何总得不到应有的尊重
Because I've been encouraged by the response to my “bubble. com” and venture capital memos, I'm going to keep writing. Over time, I collect ideas that I'm tempted to pass on to you - nothing major, but miscellany that may be of interest. Sharing them might become a habit; let me know if you think it should. Can't Get Any Respect

过去几年,IPO 和热门科技股的表现扭曲了一切传统规律。三月份达到顶峰的那一幕,必定是有史以来最大的泡沫。确实,赚钱的金额和速度前所未见。公司从商业计划到 IPO 只用一两年时间,市值动辄数十亿美元,创始人和风投支持者随之暴富。过去十二个月里,东西海岸的科技创业者和投资者买下了数千万美元的豪宅。急于入场的买家推高了私人飞机、游艇和海滨住宅的价格。艺术品和古董市场白热化。简而言之,正如我一位朋友所说,“钱被糟蹋了。”
传统的投资价值观同样被糟蹋。风险被视为投资者的朋友,谨慎被视为多余和无用。利润——甚至利润预测——都被视为多余。缓慢而稳健的赚钱方式落到了最后,风险最大的方案回报最丰厚。风投基金一年内实现三位数回报,没有利润的科技公司 IPO 一天之内就能做到。
另一方面,投资者似乎忘了自己为什么配置固定收益资产,价值股和绝对收益策略受到的忽视程度也不遑多让。1999 年 5 月,我听到安杰洛-戈登公司的约翰·安杰洛说得精辟:
二十年前,我告诉人们我能让他们年年赚 15%,他们说“那不可能。”今天,我告诉人们我能让他们年年赚 15%,他们说“谁在乎?”
The behavior of IPOs and hot tech stocks in the last few years perverted everything that traditionally had held true. The episode that crested in March must have been the greatest bubble of all times. Certainly money was made in amounts and at speeds never seen before. Companies went from business plan to IPO in a year or two, with billions of dollars assigned to them in market capitalizations or bestowed on their founders and venture capital backers. In the last twelve months, technology entrepreneurs and investors on both coasts bought homes costing several tens of millions of dollars. The line of eager buyers pushed up prices for private planes, yachts and beachfront homes. The market for art and antiques grew white hot. In short, as a friend of mine says, “money was disrespected.” Traditional investing values were equally disrespected. Risk was viewed as the investor's friend, and caution as unnecessary and unavailing. Profits - and even profit projections - were considered superfluous. The slow and steady ways of making money came in last, and the riskiest schemes paid off best. Venture capital funds produced triple-digit returns in a year, and profitless technology company IPOs did so in a day. On the other hand, investors seemed incapable of remembering why they had fixed income allocations, and value stocks and absolute return strategies weren't far behind in terms of disregard. In May of 1999, I heard John Angelo of Angelo Gordon put it brilliantly: Twenty years ago, when I told people I could make them 15% a year, year in and year out, they said “That's impossible.” Today, when I tell people I can make them 15% a year, year in and year out, they say “Who cares?”

举例来说,看看高收益债券的情况,其价格一直在下滑,部分原因在于资金持续从高收益共同基金流出(转投股市基金)。前些天有人问我,什么时候资金会重新流回高收益债券。我的回答是:当人们再次意识到 11% 的回报是笔不错的收益时。但这种对传统投资思维的轻视终将过去——事实上,它似乎正在走向尽头。总体来看,去年表现最好的投资组合今年迄今表现最差,反之亦然。传统的投资价值标准将重新获得尊重。我甚至能想象有一天,“审慎”这样的词会重新回到投资者的日常用语中。
它让你重拾信念
To illustrate, take the case of high yield bonds, whose prices have been sagging, partly because of steady capital flows out of high yield mutual funds (for redeployment in equity funds). I was asked the other day when flows into high yield bonds would resume. My answer: When people realize once again that 11 % is a good return. But this disrespect for traditional investment thinking shall pass--and in fact it appears to be in the process of doing so. In general, the portfolios that did best last year have done worst so far this year, and vice versa. Traditional investing values will be respected again. I can even imagine a day when words like “prudence” return to investors' everyday speech. It Restores Your Faith

如果常识和逻辑都不管用,我们该怎么过日子?在《泡泡网》(bubble.com)那篇文章里,我东拉西扯(去翻翻你的《芬克与瓦格纳词典》)地讲了互联网公司如何背离那个老观念——只有收入超过支出,生意才值得做。可到了 1999 年,商业模式变成了靠免费送产品来吸引眼球打广告,或者按低于成本的价格卖东西。
WebHouse 俱乐部就是免费派送模式失败的典型。它是 Priceline 分拆出来的公司,让顾客自己给日用品和汽油报个价。问题来了:生产商不愿意按顾客想付的价格供货,差价就由 WebHouse 自己贴。在《泡泡网》里我讲过几个关于赔本卖货生意人的老笑话,可我从没想过现实会这么活生生地模仿艺术。不管怎么说,WebHouse 的出资人最后没了赔钱的兴致(他们手里的 Priceline 股票从 170 美元跌到 3 美元,八成与此有关),公司 10 月 5 日停了业。
让我感到踏实的是,创业者(更重要的是,等着给他们掏钱的投资者)终于开始明白,没有利润的“商业模式”撑不下去。互联网零售公司一家家关门,尤其是那些挤在“空间”里的。听说现在硅谷员工最新的“回归模式”是“回头去做咨询”。去年高盛还愁招不到需要的 MBA,今年面试间又挤满了人。
股票投资能合理期待什么?
If common sense and logic don't work, how are we to run our lives? In “bubble.com” I battologized (look that up in your Funk & Wagnall's) regarding the dot-coms’ divergence from the old-fashioned notion that only if revenues exceed expenses is a business attractive. Instead, in 1999 business models were based on giving away products as a way to get ads in front of eyeballs, or on selling things for less than they cost. WebHouse Club is a poster child for failed giveaways. A spin-off of Priceline.com, it let customers name their own price for groceries and gas. There was a problem: manufacturers were unwilling to supply goods at the prices customers wanted to pay, so WebHouse made up the difference. In “bubble. com” I related several old jokes about the businessman who sells below cost, but I never expected to see life imitate art so precisely. Anyway, WebHouse's backers lost their enthusiasm for absorbing the losses (the fall of their Priceline stock from $170 to $3 may have had something to do with it), and the company ceased doing business on October 5. I find it reassuring that entrepreneurs (and, more significantly, the investors expected to fund them) are realizing that profitless “business models” are untenable. Internet retail firms are shutting down, especially those in overpopulated “spaces.” Now, I'm told, the newest “b-to-c” among Silicon Valley employees is “back to consulting.” Last year, Goldman Sachs had trouble recruiting the MBA it needed; this year the interview rooms are overcrowded again. What Can Reasonably Be Expected from Equities?

去年,在我担任主席的一家慈善机构投资委员会中,上演了一出我确信已在成千上万个组织中上演过的小戏剧:委员会开始质疑其保守的投资组合,并考虑是否应增持股票。于是,我们委托顾问进行了一项债券/股票配置研究。其结论颇为蹊跷。
In a little drama that I'm sure has played out at thousands of organizations in the last year, a charitable organization investment committee that I chair began to question its conservative portfolio and ask whether it should have more in equities. As a result, we commissioned some bond/stock allocation work from our consultants. Its conclusions were most curious.

他们的模型建议提高股票配置比例,预测这会带来组合整体回报的提升和风险的下降。原因何在?因为股票预计能带来 14% 的回报率,而风险被定义为五年期间平均回报率低于 8% 的可能性。
Their model called for higher equity allocations, predicting that they would lead to higher overall returns on the portfolio and lower risk. Why? Because equities were projected to return 14% and risk was defined as the probability of failing to average 8% over a fiveyear period. U

首先,我说过,我绝不会参与任何将更高的股票配置等同于更低风险的过程。我建议将风险定义为整体投资组合的波动性,这样问题就解决了。
但其次,我对股票 14% 的预期回报率提出了质疑。我说,1995 年至 1999 年间股票回报率达到了 28%;难道有人认为把这一数字减半就算是保守预测了吗?不,有人告诉我,支持这一预测的主要依据是股票 13% 的长期回报率——(我一直以为这个数字是 10% 左右,但看来过去五年改变了一切。)
我只能想到一种回应方式:我愿意拿出我的钱和那位顾问的研究人员打赌,“押空头”。我强烈怀疑未来十年股票的回报率会达到 14% 或任何接近这一水平的数字。企业盈利传统上一直以个位数增长,而且我不认为这种情况会有重大改变。由于市盈率不太可能进一步上升,股息也微乎其微,个位数的盈利增长在可预见的未来充其量只能转化为个位数的平均股票表现。
归根结底,我觉得人们过度依赖了股票的历史平均回报率,无论是 1929 年至 1992 年的 10%,还是 1940 年至 1999 年的 13%。人们忽略的事实是,在这些时期开始时市盈率要低得多,而自那以后市盈率大幅上升。我就是不相信市盈率的进一步扩张可以被指望。我如何看待这个问题?我问那些看涨者一个问题:在几十倍的市盈率下买入股票的平均表现如何?我不认为回报率能达到两位数。我甚至不确定它是否为正。
理解市场危机的框架
First, I said, I would never have any part in a process that equated higher equity allocations with lower risk. I suggested that risk be defined as overall portfolio volatility, and that took care of that. But second, I questioned the 14% projected return from equities. Equities returned 28% in 1995-99, I said; did someone think halving that made for a conservative projection? No, I was told, the support mostly came-from the 13% long-run return on equities:--(I always thought it was 10% or so, but it seems the last five years have changed all that.) I could only think of one way to respond: I offered to put up my money against that of the consultant's researchers and “take the under.” I doubt strongly that equities will return 14% or anything like it in the next decade. Corporate earnings have traditionally grown at single-digit rates, and I don't feel that's about to change substantially. With p/e ratios unlikely to rise further and dividends immaterial, single-digit earnings growth should translate into single-digit average equity performance at best for the foreseeable future. In the end, I feel there has been unreasonable reliance on the average historic return from equities, be it 10% for 1929-92 or 13% for 1940-99. What's been lost track of is the fact that p/e ratios were much lower when these periods began and since then have risen substantially. I just don't believe that further p/e expansion can be counted on. How do I view the issue? I ask the bulls one question: What's been the average performance of stocks bought at p/e ratios in the twenties? I don't think the return has been in double digits. I'm not even sure it's been positive. A Framework for Understanding Market Crisis

我想请大家留意一篇出色的论文,题为上述标题,作者是理查德·布克斯塔伯,摩尔资本管理公司的风险管理负责人。该文发表于 AIMR 研讨会“风险管理:原则与实践”的会议论文集中,时间为 1999 年 8 月。聪明人的本事,在于把那些我们或许想过却从未成形或表达出来的想法,用清晰的逻辑语言说出来。在文章中,布克斯塔伯对市场危机背后的驱动力做了出色的阐释。
我将尝试总结他的分析,大量借用他的原话,同时加入我自己的理解和侧重点。读起来可能会有些费劲,但我相信你会觉得物有所值。
I want to call your attention to an excellent paper with the above title written by Richard Bookstaber, head of risk management for Moore Capital Management. It was published in the proceedings of an AIMR seminar on “Risk Management: Principles and Practices” (August, 1999). What smart people do is put into logical words the thoughts we may have had but never formulated or expressed. In his article, Bookstaber has done a great job of explaining the forces behind market crisis. I'll try to summarize his analysis, borrowing extensively from his words but adding my own interpretation and emphasis, there'll be some slow going, but I think you'll find it worthwhile.
大多数人以为,证券价格的波动主要源于市场对企业、经济或地缘政治事件——即所谓的“基本面”——信息的贴现。然而,你要是跟交易员坐在一起,很容易就会发现,价格的变动始终不由基本面信息驱动。
Most people think security price movements result primarily from the market's discounting of information about corporate, economic or geopolitical events - socalled “fundamentals.” If you sit with a trader, however, it's easy to observe that prices are always moving in response to things other than fundamental information.

布克施塔伯说,“日内价格变动的主要原因是对流动性的需求……取代了学术界关于市场作用的传统观点——即市场是有效的,仅服务于信息传递——这一观点认为,市场的角色是为流动性需求者提供即时性……接受市场存在的意义在于满足流动性需求与流动性供给这一理念,就为理解市场危机的成因搭建了框架,而危机恰恰是流动性和即时性最为关键的时刻。”
Bookstaber says “the principal reason for intraday price movement is the demand for liquidity .... In place of the conventional academic perspective of the role of the market, in which the market is efficient and exists solely for informational purposes, this view is that the role of the market is to provide immediacy for liquidity demanders.....By accepting the notion that markets exist to satisfy liquidity demand and liquidity supply, the framework is in place for understanding what causes market crises, which are the times when liquidity and immediacy matter most.”
“流动性需求方是即时性的需求方。”我会把他们描述为资产的到期持有者,比如投资者和套期保值者,他们有时有强烈的调整头寸的需求:当情况紧急时,“决定性特征是时间比价格更重要……他们需要立即完成交易,并愿意为此付出代价。”
“Liquidity demanders are demanders of immediacy.” I would describe them as holders of assets in due course, such as investors and hedgers, who from time to time have a strong need to adjust their positions: When there's urgency, “the defining characteristic is that time is more important than price .... they need to get the trade done immediately and are willing to pay to do so.”
“流动性提供者满足流动性需求。”他们可能是大宗交易商、对冲基金经理,或是手握现金、对某资产价值有坚定判断的投机者,他们“等待机会,当流动性需求方对资金的需求导致价格偏离(资产真实价值)时出手。流动性提供者随后以该价格提供流动性。”他们提供的是流动性;提供流动性对他们而言意味着风险(随着市场波动加剧、流动性下降,这种风险会上升);而他们预期赚取的利润,正是承担这份风险的代价。“对流动性提供者来说,价格远比时间重要。”
“Liquidity suppliers meet the liquidity demand.” They may be block traders, hedge fund managers or speculators with ready cash and a strong view of an asset's value who “wait for an opportunity when the liquidity demander's need for liquidity creates a divergence in price [from the asset's true value]. Liquidity suppliers then provide the liquidity at that price.” What they offer is liquidity; providing liquidity entails risk to them (which increases as the market's volatility increases and as its liquidity decreases); and the profit they expect to make is their price for accepting this risk. “To liquidity suppliers, price matters much more than time.”
通常,当某样东西的价格下跌时,愿意卖的人会减少,愿意买的人会增多。但在危机中,“市场价格会变得反经济”,情况正好相反。“价格下跌非但不会阻止人们抛售,反而会引发越来越多的卖盘;非但不会吸引买家,反而会将潜在买家赶出市场(甚至更糟,把潜在买家变成卖家)。”这种现象的成因多种多样,有的出于交易层面(比如收到追加保证金通知),有的出于情绪层面(比如感到恐慌)。流动性需求方的数量增加,而且他们的动机变得更加迫切。“流动性需求方用价格来吸引流动性供给方,这有时管用,有时不管用。在高风险或危机市场中,价格下跌实际上会减少(流动性)供给,同时增加需求。”
Usually when the price of something falls, fewer people want to sell it and more want to buy it. But in a crisis, “market prices become countereconomic,” and the reverse becomes true. “A falling price, instead of deterring people from selling, triggers a growing flood of selling, and instead of attracting buyers, a falling price drives potential buyers from the market (or, even worse, turns potential buyers into sellers.)” This phenomenon can occur for reasons ranging from transactional (they receive margin calls) to emotional (they get scared). The number of liquidity demanders increases, and they become more highly motivated. “Liquidity demanders use price to attract liquidity suppliers, which sometimes works and sometimes does not. In a high-risk or crisis market, the drop in prices actually reduces supply [of liquidity] and increases demand.”
危机时刻,流动性提供者会变得稀缺。也许他们在最初 10% 的下跌中已耗尽了资本,弹药全无。也许市场波动加剧、流动性收缩,令他们愿意支付的价格打了折扣。也许他们也一样恐慌。布克斯塔伯回忆起 1987 年股灾。第一轮下跌之后,流动性提供者“早已‘出手’,在波动率低得多的价位上冒险投入资本,如今却被管理层强制平仓,更糟糕的,连饭碗都丢了。即便保住职位的人,也把资本搁在场外。在遍地疮痍之际入市,被认为是不明智的……信息并非剧烈价格波动的元凶。真正的元凶是危机引发的流动性需求,而此时流动性提供者正从市场萎缩退却。”
In times of crisis, liquidity suppliers become scarce. Maybe they spent their capital in the first 10% decline and are out of powder. Maybe the market's increased volatility and decreased liquidity have reduced the price they're willing to pay. And maybe they're scared, too. Bookstaber recalls the Crash of 1987. After the first leg down, liquidity suppliers “had already ‘made their move,’ risking their capital at much lower levels of volatility, and now were stopped out of their positions by management or, worse still, had lost their jobs. Even those who still had their jobs kept their capital on the sidelines. Entering the market in the face of widespread destruction was considered imprudent ... Information did not cause the dramatic price volatility. It was caused by the crisis-induced demand for liquidity at a time that liquidity suppliers were shrinking from the market.”

“市场危机最令人不安的一点是,分散化策略失效。原本互不相关的资产突然变得高度相关,所有头寸一起下跌。分散化失效的原因在于,在波动剧烈的市场中,所有资产实际上是一样的。平时区分它们的因素不再重要。重要的不再是资产之间的经济或金融关系,而是它们共处栖息地的程度。重要的是谁持有这些资产。”近年来,大多数投资者感到自在的“栖息地”已经扩大。进入壁垒降低,信息获取渠道增加,也许最重要的是,大多数投资者在海外市场的尝试都得到了回报。因此,“市场参与者变得彼此更像,这意味着流动性需求者几乎持有相同的资产,并争夺一切可用的流动性来源。”如果它们被同一批交易者持有,“两种不相关的资产会变得高度相关,因为一种资产的亏损会迫使交易者清算另一种资产。”这很好地解释了为什么 1998 年 9 月长期资本管理公司和新兴市场崩盘时,高收益债券和其他不相关资产类别也随之下跌。
“One of the most troubling aspects of a market crisis is that diversification strategies fail. Assets that are uncorrelated suddenly become highly correlated, and all positions go down together. The reason for the lack of diversification is that in a [volatile] market, all assets in fact are the same. The factors that differentiate them in normal times are no longer relevant. What matters is no longer the economic or financial relationship between assets but the degree to which they share habitat. What matters is who holds the assets.” In recent years, the “habitat” in which most investors feel comfortable has expanded. Barriers to entry have fallen, access to information has increased and, perhaps most importantly, most investors' forays abroad have been rewarded. Thus “market participants become more like one another, which means that liquidity demanders all [hold] pretty much the same assets and grab whatever sources of liquidity are available.” If they are held by the same-traders, “two types of unrelated-assets will become highly correlated because a loss in the one asset will force the traders to liquidate the other.” That's not a bad explanation for the fact that when Long-Term Capital and the emerging markets crashed in September 1998, high yield bonds and other unrelated asset classes fell with them.
我希望你能从上述内容中识别出橡树资本(Oaktree)方法论背后的部分要素,正如我们处理不良债务的工作所展现的那样。
I hope you'll recognize in the above some of the elements behind the Oaktree approach, as exemplified by our work with distressed debt.
我们寻找布克施塔伯所说的“流动性需求方”,他们有着外生性的动机。我们称他们为被迫卖出者,他们为我们带来最划算的买卖。
We look for Bookstaber's “liquidity demanders,” with their exogenous motivations. We call them forced sellers, and they provide our best bargains.
当“非经济性”市场状况加剧抛售压力、即便资产价格持续走低之时,我们便借机出手。
We take advantage when “noneconomic” market conditions increase the pressure to sell even as asset prices move lower.
我们极少主动找持股人收购,宁可等他们打电话来。这样一来,我们是“流动性提供方”,而不是急切的买家。听我一句,急切的买家要付更高的价钱。
And we rarely approach holders to buy, preferring to wait until they call us. In that way we are “liquidity suppliers” rather than eager buyers. Take it from me, the latter pay more.
我们中的许多人可能都有过像布克斯塔伯那样的想法,在我从事资金管理 30 多年的生涯中,有无数机会目睹流动性需求飙升、流动性供给枯竭、价格崩溃以及分散投资失效的情形。但我敬佩那些能将“人尽皆知”的道理纳入严谨框架的人。
说到恐慌,我们都清楚当卖出意愿远超买入意愿时发生的惨状。但我认为布克斯塔伯的分析同样适用于相反的情形——当买入欲望压倒卖出意愿的时刻。这被称为买入恐慌,它同样是一场危机,尽管由于直接结果是盈利而非亏损,人们谈论它时措辞不同。1999 年无疑与 1987 年一样,是一场非理性的、由流动性驱动的危机。虽然今年迄今已经显现出一些后果,但我认为还有更多后续影响。
Many of us may have had thoughts like Bookstaber's, and in my 30+ years in money management I've had plenty of chances to watch liquidity demand soar, liquidity supply dry up, prices collapse and diversification fail. But I respect someone who can put into a rigorous framework that which “everybody knows.” Speaking of panics, we all recognize the carnage that occurs when the desire to sell far exceeds the willingness to buy. But I think Bookstaber's analysis applies equally to the opposite - times when the desire to buy outstrips the willingness to sell. It's called a buying panic and represents no less of a crisis, even though - because the immediate result is profit rather than loss - it is discussed in different terms. Certainly 1999 was just as much of an irrational, liquidity-driven crisis as 1987. While some of the ramifications have been seen thus far this year, I think there's more to come.

知识与信息之别
Knowledge Versus Information

如果布克斯塔伯的文章对某一市场现象做出了精彩解读,那么反之如何?举个例子,我想到詹姆斯·K·格拉斯曼在《华尔街日报》8 月 30 日发表的文章《股票骗局应增强对市场的信心》。格拉斯曼的名字你可能熟悉,因为我 2000 年 5 月 1 日的备忘录曾质疑他合著的《道指 36000 点》一书。现在,再次与他商榷,实为乐事。格拉斯曼的书认为道指应达到 36000 点,因为股票的市盈率应远高于当前水平。市盈率应更高,是因为股票风险极小,投资者无需计入风险溢价。我当时认为这个论点毫无道理,如今也不觉得这篇文章有何说服力。这次,格拉斯曼提出,大幅降低股票风险的因素之一是市场所用的技术,尤其是互联网。由于信息传播得如此迅速和全面,投资所涉风险降低,因此股票是更好的去处。他说:“互联网——仅作为快速传播金融信息的工具——已产生抬高股价的效果,或许这种效果是永久性的。这样看来,新技术为美国投资者增添了数千亿美元的财富。”
矛盾的是,格拉斯曼在 Emulex 事件中找到了证据。2000 年 8 月 25 日,一则虚假新闻稿在互联网上流传,导致 Emulex 股价在二十分钟内从 103 美元跌至 45 美元。停牌几个小时后,更正信息使其重回 100 美元以上。格拉斯曼对市场的评价是:“效率令人目眩。”他因虚假数据和更正信息都传播得如此迅速而感到安心。我却认为,信息以极快速度和极大规模普及传播,常常让人无法核实、提炼和理解,这本身并不会让市场更安全。若要证明,看看波动性的趋势即可。媒体炒作和其他短期导向的事态似乎不可避免地使市场变得更加凶险。
纵观当今的大众市场和随之而来的信息洪流,我的合伙人谢尔顿·斯通把投资者比作船上的乘客,成群地跑来跑去——听到新信息就涌向一边,然后又跑回另一边。这使航行颠簸不已。
格拉斯曼错在哪里?在我看来,他的错误在下面这句话中显而易见:市场对公司了解得如此之多、如此之快,以至于其对价值的评估具备了一种即时的效率和准确性。
If Bookstaber's article made brilliant sense of a market phenomenon, what's the opposite? For an example, I would look to “Stock Hoax Should Affirm Faith in Markets” by James K. Glassman (Wall Street Journal, August 30). Glassman's name may be familiar to you, because my memo of May 1, 2000 took issue with “Dow 36,000,” a book he co-authored. Now it's a pleasure to take issue with him again. Glassman's book said the Dow should be at 36,000 because stocks' multiples should be much higher than they are. Multiples should be higher because there's so little risk in stocks, and thus investors needn't incorporate a risk premium. I didn't think that argument made any sense, and I don't think the recent article makes any, either. This time, Glassman argues that one of the things greatly reducing the riskiness of stocks is the technology being employed in the markets, most notably the Internet. Because information is disseminated so rapidly and thoroughly, investing entails less risk, so stocks are a better place to be. As he puts it, “The Internet - simply as a tool to get financial information out speedily - has had the effect of raising stock prices, perhaps permanently. In that way, the new technology has added hundreds of billions of dollars to the wealth of U.S. investors.” Paradoxically, Glassman finds proof of this in the Emulex incident. On August 25, 2000, a false press release was picked up on the Internet, taking Emulex stock from $103 to $45 within twenty minutes. After a few-hour trading halt, corrected information took it back above $100. Glassman's term for the markets: “dazzling in their efficiency.” He finds comfort in the fact that both the falsified data and the correction were disseminated so quickly. I feel the rapid and universal distribution of information often at speeds and in amounts that make it impossible to verify, distill and understand does nothing to make the markets safer per se. For proof, look at the trend in volatility. It seems inescapable that media hype and other short-term oriented developments have made the markets more treacherous. Looking at today' s mass market and the associated flood of information, my partner Sheldon Stone sees investors as passengers on a boat, running back and forth en masse -to one side in response to new information, and then back to the other. That makes for a rocky crossing. Where does Glassman go wrong? To me, his error is obvious in the following sentence: Markets know so much more about companies, and know it so quickly, that their assessments of worth have an up-to-the-minute efficiency and accuracy.

对我的核心结论是:效率与准确是两码事。正如我在五月备忘录中所写,投资者会迅速将新信息纳入对证券价值的估算,市场也会迅速反映对价值的共识看法……但这并不意味着共识就是正确的。信息不等于知识。投资者拥有数据并不意味着他们理解其重要意义。如果投资者的知识确实在增长,股市波动就不会像现在这样剧烈。正如那句关于蠢人的谚语所说:“他对一切的价格了如指掌,却对价值一无所知。”
The bottom line for me: Efficiency and accuracy are two very different things. As I wrote in my May memo, investors rapidly incorporate new information into their estimates of security values, and the market rapidly reflects the consensus view of values,...but that doesn't mean the consensus is right. Information isn't knowledge. The mere fact that investors have data doesn't mean they understand its significance. If investors' knowledge was really growing, stock volatility wouldn't be increasing as dramatically as it is. As the adage says of the fool, “he knows the price of everything and the value of nothing.”
