推理小说(who·dun·it – hōō dun´ it)n. 一种叙述谋杀案或系列谋杀案及其凶手侦破过程的叙事作品(《兰登书屋英语词典》)
次贷危机、信贷紧缩和可能的经济衰退成了人们每日谈论的话题。除了想聊聊事情怎么变成这样、未来又会怎样,很多人还急着讨论该怪谁。这份备忘录的目的,就是说说我认为责任在哪里。
who·dun·it – (hōō dun´ it) n. a narrative dealing with a murder or a series of murders and the detection of the criminal (The Random House Dictionary of the English Language) The subprime crisis, credit crunch and possible recession are subjects of daily conversation. In addition to wanting to talk about how things got this way and what’s going to happen in the future, a lot of people are eager to discuss who’s to blame. It’s the purpose of this memo to say where I think responsibility lies. The Subprime Factory

听说过这样一句话:法律就像香肠,制作过程看不得。我想说,还有一样东西的制造流程同样令人作呕,那就是次级抵押贷款。
本世纪次级抵押贷款工厂的大规模扩张,源于华尔街有能力大量销售与抵押贷款相关的债务抵押债券(CDO)。次级抵押贷款的高利率,让华尔街得以承诺 CDO 低层级部分的高回报和高层级部分的高安全性。只要评级够高,这些债务在潜在买家眼里就极具吸引力。于是,大量底层原材料——次级抵押贷款——就有了用武之地。然而,华尔街卖出的大红肠三明治,比手头的大红肠还多。也就是说,市场对高收益抵押贷款衍生证券的胃口,超过了合格借款人的供给。这不成问题:只要给生产端加 incentives,再对信用资质睁一只眼闭一只眼就行。
抵押贷款经纪人在这个过程中扮演了关键角色,而且往往很不光彩。他们的任务就是大量制造抵押贷款,利益驱动也就在这儿。既然他们和华尔街公司都不打算长期持有这些贷款,重点自然落在数量上,而不是信用质量上。放贷是好事,拒贷是坏事。路易斯安那州经纪人凯文·施密特公司的网站说得最直白:“不点头,就没钱拿。”(《华尔街日报》,1 月 17 日)《华尔街日报》接着指出:“关键参与者的分成,往往来自交易最初设计时的预估价值,而非它长期实际兑现的成果。”
I’ve heard it said about laws that, “like sausages, you don’t want to see how they’re made.” I’d like to suggest something else where the manufacturing process was particularly distasteful: subprime mortgages. This decade’s vast expansion of the subprime factory originated in the ability of Wall Street to sell a lot of mortgage-related Collateralized Debt Obligations, or CDOs. The high interest rates on subprime mortgages enabled the Street to promise a lot of return on the lower CDO tranches and a lot of safety on the upper ones. With high-enough ratings, the debt looked very attractive to potential buyers. Thus, there was a use for large amounts of the underlying raw material: subprime mortgages. It happened, however, that Wall Street could sell more bologna sandwiches than there was bologna. That is, there was more appetite for securities built from high yielding mortgages than there were qualified borrowers. No problem: just provide incentives to increase production and turn a blind eye to creditworthiness. Mortgage brokers played an essential and often ugly part in this process. They were tasked with creating mortgages in quantity, and that’s where their incentives lay. Since neither they nor the Wall Street firms would hold the mortgages for long, the emphasis was on volume rather than creditworthiness. Making loans was good; rejections were bad. The website of broker Kevin Schmidt’s firm in Louisiana said it best, “We don’t get paid unless we say YES.” (The Wall Street Journal, January 17) The Journal went on to point out that, “Key players often get a cut from what a transaction is supposed to be worth when first structured, not what it actually delivers in the long term.”

因此,我认为抵押贷款经纪人犯下了许多过错。他们向许多次级借款人提供的债务额度超出了他们的承受能力。他们向借款人保证,总能以诱人的初始利率再融资获得新贷款,因此不必担心利率重置为市场水平。他们可能没有把所有条款解释清楚,还耍了老一套的诱饵调包把戏。他们向第一抵押权人隐瞒了借款人同时也在用房屋净值借款的事实。而且,我确信有些人还怂恿借款人虚报收入,打着“大家都这么干”、“凭什么乔和苏的房子就该比你的好”和“没人会受伤害”的旗号。
评估师在这个过程中同样起了负面作用。在房价稳定的年代,评估基于既定参数,比如每平方英尺的价格。但随着房价快速上涨,他们只能参照其他大幅增值房产的“可比交易”。和信用评级机构一样,评估师给一个有缺陷的过程披上了体面的外衣。而且,正如评级机构那样,工作往往落到了那些愿意给出最高估值的评估师手里。我读到过一些报道,有些评估师因为过于保守、限制了贷款规模而被列入黑名单。据《洛杉矶时报》1 月 27 日报道,沃顿商学院教授苏珊·瓦赫特估计,“仅 2006 年一年,评估师就帮助推高了 1350 亿美元的抵押贷款价值。”借款人、房屋卖家、抵押贷款经纪人和华尔街都从高估值中获益。当交易的任何一方都不希望评估保守时,这从根本上就错了。但当遥远的、有评级保障的、购买分割打包抵押贷款证券的买家取代了那些自担风险、打算持有到期的贷款人时,情况就变成了这样。
抵押贷款保险公司也扮演了类似角色,他们借出自己的信誉背书,从而暗示这些工具是安全的。每个人都认为购买保险是谨慎之举。当风险得到保险保障时,承受风险的人会觉得自己安全了,因而行为方式与没有保险时不同。但当保险公司错误计算了所涉风险,签发保单的覆盖范围超出了其资本在困难时期所能支撑的程度时,会发生什么?在极端情况下,损失可能得不到补偿,这意味着投保人并没有真正拥有他们以为的保护,他们的处境比自己预想的更危险。当然,在这个周期里,不够谨慎的保险公司助长了对超出预期风险的承担。
我们要记住,抵押贷款借款人也不该被轻易放过。这要么是愚蠢或贪婪,要么是天真或道德败坏。往好里说,他们承担了自己并不了解的巨大财务责任;往坏里说,他们就是骗子。许多人以高于需要收入证明贷款的利率申请了“无文件贷款”。为什么?我猜想他们是想自由地撒谎。而且,许多人同意了自己看不懂的条款。但只要结果是能有一套好房子,初始月供又低(过程中可能还能套现),又何必担心呢?我不愿看到借款人受苦,但每个人都自愿参与了一桩好得令人难以置信的交易。
Thus I believe mortgage brokers committed many sins. They offered more debt than many subprime borrowers could carry. They assured borrowers that they’d always be able to refinance into new loans at teaser rates, so they needn’t worry about a reset to market rates. They probably weren’t clear on all the terms and practiced the old bait-andswitch. They hid from first-mortgage lenders the fact that borrowers were borrowing their equity too. And I’m sure some encouraged borrowers to lie about their incomes, invoking “Everyone does it,” “Why should Joe and Sue have a nicer house than you?” and “Nobody gets hurt.” Appraisers made a similarly negative contribution to the process. In the days when home prices were stable, appraisals were based on established parameters like price per square foot. But with prices rising rapidly, they could only reference “comps” to other highly appreciated homes. Like the credit rating agencies, appraisers lent a veneer of respectability to a faulty process. And like rating agencies, the job probably went to the appraiser willing to assign the highest value. I’ve read about appraisers being blacklisted because they were too conservative, restraining loan volume. According to the L.A. Times of January 27, a Wharton professor, Susan Wachter, has estimated that “appraisers helped inflate mortgage values by $135 billion during 2006 alone.” Borrowers, home sellers, mortgage brokers and Wall Street all had a vested interest in seeing high values assigned. There’s something fundamentally wrong when there’s no party to a transaction who wants the appraisal to be conservative. But that became the case when far-away, ratings-assured buyers of sliced-and-diced mortgage securities took the place of lenders risking their own money and expecting to hold to maturity. Mortgage insurers played a similar role by lending their imprimatur and thus implying instruments were safe. Everyone thinks of taking out insurance as a cautious thing to do. When risks are insured, the people exposed to them believe they’re safe to behave differently than they otherwise would. But what happens when the insurers miscalculate the risks involved, and thus issue more coverage than their capital can support in tough times? In the extreme, losses can go unreimbursed, meaning the insureds don’t really have the protection they think they have and their situation is riskier than they intended. Certainly in this cycle, insufficiently cautious insurers abetted the bearing of risks that have exceeded expectations. Let’s remember that the mortgage borrowers don’t deserve a free pass. It was stupidity or cupidity, naïveté or moral turpitude. At best they took on massive financial responsibilities they didn’t understand, and at worst they were fraudsters. Many took out “no-doc loans” at interest rates above those charged on loans requiring documentation of income. Why? I assume they wanted to be free to lie. And many agreed to terms they couldn’t decipher. But why worry, if the result is a great house at a low initial monthly payment (and maybe cash taken out in the process)? I hate to see the borrowers’ suffering, but each one willingly participated in a deal that was too good to be true.

把抵押贷款变成债务抵押债券
Turning Mortgage Loans into CDOs
U
U
CDO 投资者因次贷相关债务损失超过 1000 亿美元(截至目前)而登上头条。有人卖给他们某种事后被证明严重高估的东西。因此,我必须从投资银行家说起。同样的问题是:他们是天真还是贪婪?
当橡树资本考虑新产品时,我们会问一系列问题:第一,它对客户是否有效;回报潜力如何;风险是否可控?第二,我们能卖出去吗;对我们是否有利可图?华尔街在次贷 CDO 上问的是哪一组问题?毫无疑问是第二组,但结果并不能保证第一组。他们卖的东西大规模失败,而社会对他们的评判却多少有些宽容。说来恰当,像美林、花旗集团和瑞银这样的投资银行吃了不少自己做的菜(也承担了相当一部分损失)。但这并不能免除他们的责任,因为其他人也受了伤害。
我坚定信奉买者自负原则,但这并不意味着卖方不存在不当行为。他们是否做过深思熟虑且平衡的尽职调查?他们是否充分考虑过买方的下行风险?他们是否怀疑过那笔好交易可能只是幻象?他们是否看到抵押贷款发放流程中的缺陷?当他们整理数据去说服客户和评级机构 CDO 是安全的时,他们是否考虑过数据的稀疏性或有限的相关性?他们是否隐瞒了 CDO 投资组合中“例外”项——即不符合最低贷款标准的抵押贷款——的信息,正如纽约州总检察长正在调查的那样(《华尔街日报》,1 月 31 日)?
其中一些问题同样适用于 CDO 经理的角色。我没有近距离接触这个过程——橡树资本没有参与其中——但我相信经理们会见了投资银行家,而后者提出近乎交钥匙的方案:“流程是这样的。文件已备好。资产在库存里。债务已为发行准备好。你的费用是每 10 亿美元收 x 百万美元。”经理们是否审查过这个过程?他们是否独立评估过风险?还是他们只是签上了这台神奇收费机器的合同?
接下来,在我看来,是信用评级机构。总之,CDO 债务的评级过程从头到尾都是错的,而这个过程是受机构对利润的贪婪驱动。评级机构与 CDO 发起人合作设计产品,那他们又如何能客观评估这些产品?他们从被评级的公司那里拿钱;大家都这么做,但这并不意味着这种安排能让他们保持客观。他们争抢业务,费用归给出评级最高的那家机构。
但归根结底,评级机构最大的失职在于给那些他们无法准确评估风险的证券背书。最终违约率至关重要却无从知晓。次贷违约的历史数据与抵押贷款相关,而
CDO investors are in the headlines for having lost $100 billion-plus (thus far) on subprime-related obligations. Someone sold them something that turned out to have been massively overpriced. Thus I have to start with the investment bankers. Again, was it naïveté or avarice? When Oaktree considers a new product, we ask a number of questions: First, will it work for our clients; what’s the return potential; and are the risks controllable? And second, can we sell it; and will it be profitable for us? Which of these did Wall Street ask regarding subprime CDOs? The second group of questions undoubtedly, but the results provide no assurance regarding the first. They sold something that failed massively, and they’ve gotten off somewhat easy in terms of society’s judgment. Fittingly, investment banks like Merrill Lynch, Citigroup and UBS ate a lot of their own cooking (and a good part of the losses). But that does not absolve them of responsibility, for others were hurt as well. I believe firmly in caveat emptor, but that doesn’t mean there’s no such thing as misconduct on the part of sellers. Did they perform thoughtful and balanced due diligence? Did they give enough thought to the buyers’ downside risk? Did they suspect that the good deal might be illusory? Did they see the flaws in the mortgage origination process? When they marshaled data with which to prove to customers and rating agencies that CDOs were secure, did they consider the data’s sparseness or limited relevance? Did they fail to disclose information regarding the “exceptions” in CDO portfolios – mortgages that didn’t meet minimum lending standards – as the New York Attorney General is investigating (WSJ, January 31)? Some of the same questions can be asked about the role of CDO managers. I haven’t been close to the process – Oaktree didn’t have any involvement – but I believe managers met with investment bankers who offered a near-turnkey proposal: “Here’s how it works. The documents are ready to go. We have the assets in inventory. The debt is teed up for issuance. Your fees will be x million per billion.” Did the managers vet the process? Did they undertake an independent effort to gauge the risks? Or did they just sign on to the magical fee machine? Next up, in my opinion, are the credit rating agencies. In summary, everything was wrong with the process through which CDO debt was rated, a process fed by the agencies’ hunger for profit. The agencies worked with CDO sponsors to design the products, so how could they then be objective in evaluating them? They accepted payment from the companies whose offerings they were rating; they all did, but that doesn’t mean the arrangement left them objective. They competed for the business, with the fees going to the agency that would assign the highest rating. But in the end, the rating agencies’ greatest failing lay in giving their blessing to securities whose risk they couldn’t accurately assess. The eventual default rate was crucial and unknowable. The historic data on subprime defaults related to mortgages that

这些评级是通过一个迥然不同的流程和激励体系颁布的。但我无法想象有任何机构会说:“风险不可知,我们实在无法给出评级。”
我们怎么知道评级机构搞砸了?迄今高达十二位数的损失就是一个相当明确的信号。《华尔街日报》1 月 31 日的一篇文章给出了另一个证据:
标普下调或威胁下调逾 8000 项抵押贷款投资的评级,并预计,越来越多的金融机构最终将面临总计超过 2650 亿美元的抵押贷款证券损失……
标普的评级行动波及 5340 亿美元的抵押贷款相关投资,其中包括 2006 年和 2007 年上半年评级的 47% 的美国次级抵押贷款债券……
标普如今已将 2006 年发行的 69% 的三 A 级次级债券列入负面观察名单。(着重号系引者所加。)
我看这堪称一份彻底的起诉书。它表明流程存在缺陷,而非偶发失误。单一险种保险公司的情况与评级机构惊人地相似……但多了一个波折。这些公司原本经营着一项不错但乏味且增长缓慢的市政债券保险业务。由于市政债券违约如此罕见,它们几乎不需要多少资本来覆盖潜在损失,而且它们大概开始觉得自己在评估损失方面相当在行。到了二十世纪九十年代,它们得出结论:抵押贷款支持证券的风险并不比市政债券高。(事实并非如此:MBIA 在第四季度录得 7.14 亿美元的抵押贷款相关损失,而其在 36 年历史中市政债券的损失共计 9.2 亿美元,平均每年 2600 万美元。)于是,这些保险公司拿出自己的资本和精明,为 1250 亿美元的债务抵押债券(CDO)债务提供了担保。它们的无知与评级机构如出一辙,但它们承诺对任何损失负责赔偿。
结果可能是灾难性的。它们的资本显然不足以覆盖其责任。例如,ACA 金融担保公司凭借其 4.25 亿美元的资本,承保了 690 亿美元的信用保护。如果 CDO 损失侵蚀单一险种保险公司的资本,和/或导致它们失去三 A 评级,那么它们对其担保的逾 1 万亿美元市政债券所作承诺的可信度就会下降。失去三 A 评级将损害未到期受保市政债券,给整个市政债券市场造成严重破坏,并使新债券发行更加困难——而正值各城市和各州需要资金来弥补因经济和次级债问题导致的收入下降之际。同样至关重要的是,这将要求受保 CDO 票据的持有人进行额外的减记。单一险种保险公司的问题已经开始加剧信贷危机,人们正仓促寻找解决方案(迄今尚无成效)。
CDO 创设过程中的所有参与者都参与了一项我们不妨称为“评级套利”的活动。如果你能把一堆评级较低的资产——在不以任何方式增加抵押品内在价值的情况下——变成评级较高的证券,并
were issued through a far different process and incentive system. But I can’t imagine any agency saying, “The risks are unknowable; we just can’t assign a rating.” How do we know the agencies bobbled the ball? The twelve-digit losses to date give a pretty good indication. An article in The Wall Street Journal of January 31 gives another: Standard & Poor’s downgraded or threatened to downgrade more than 8,000 mortgage investments and projected a widening array of financial institutions would ultimately face mortgage securities losses totaling more than $265 billion. . . S&P’s rating actions touched on $534 billion in mortgage-related investments, including 47% of the U.S. subprime mortgage bonds rated in 2006 and the first half of 2007. . . S&P . . . has now placed 69% of the triple-A rated subprime bonds from 2006 on negative watch. (emphasis added). I’d call that a thorough indictment. It indicates a flawed process, not occasional error. The situation is remarkably similar for the monoline insurers . . . but with an added wrinkle. These firms carved out a good but dull and slow-growing business in insuring municipal bonds. Since munis default so infrequently, they needed little in the way of capital to cover potential losses, and they probably started to feel they were pretty good at gauging losses. In the 1990s, they concluded that mortgage-backed securities were no more risky than munis. (Not so, it turns out: MBIA recorded mortgage-related losses of $714 million in the fourth quarter, versus losses of $920 million on munis over its 36year history, for an average of $26 million a year.) Thus the insurers applied their capital and acumen to insuring $125 billion of CDO debt. They acted out of the same ignorance as the rating agencies, but they promised to make good on any losses. The results are potentially disastrous. Their capital is clearly insufficient to cover their responsibilities. ACA Financial Guaranty Corp., for example, wrote $69 billion of credit protection on the basis of its $425 million of capital. And if CDO losses eat into the monoline insurers’ capital and/or cause them to lose their triple-A ratings, it will diminish the reliability of their assurance with regard to $1 trillion-plus of munis they backed. Loss of the triple-A rating would hurt the outstanding insured munis, wreak havoc in the muni market generally, and make it harder for new bonds to be issued, at just the time that cities and states need money to cover economy- and subprime-related revenue declines. Also of critical importance, it will require holders of insured CDO paper to take additional writedowns. The monoline situation has begun to contribute to the credit crisis, and people are scurrying to find a solution (thus far without success). All the participants in the CDO creation process took part in an activity we can call “ratings arbitrage.” If you can take a bunch of assets with low ratings and – without adding to the intrinsic value of the collateral in any way – turn them into securities with

评级高得多的证券,你就能赚大钱。但能够做到这一点本身就说明出了问题。(换句话说,如果一开始有 100 磅碎牛肉,最后却卖出 10 磅狗粮、40 磅牛里脊和 50 磅菲力牛排,那食品标签法规肯定没起作用。)以 CDO 为例,评级和保险由低估风险的一方提供,最终产品被那些愿意参与这场所谓的奇迹、却不问尖锐问题的人卖出——也被同样的人买进。风险管理的失败
much higher average ratings, you can make a lot of money. But the ability to do so means there’s something wrong.

In the case of CDOs, ratings and insurance were supplied by parties who underestimated the risk, and the end product was sold – and bought – by people who were willing to participate in this purported miracle without asking the hard questions. The Failure of Risk Management
U

长期以来,我一直对风险管理作为一种独立投资纪律持批评态度。如今,支持我这一观点的有力证据显而易见:1998 年长期资本管理公司倒闭后,大多数金融机构任命了风险管理人员,但这似乎并未帮助他们避开次贷危机。如果你信任某人足够专业,可以做出投资决策,那么这个人就是最能评估其风险的人。如果你信任某人来构建投资组合,那么他们最能判断各项资产在组合中如何协同表现。在孤立的风险管理职能中,我感觉那些对底层投资了解较少的人,反而在质疑那些了解更多的人。
有一个持续存在的困境,正如我在 1970 年贴在公告栏上的一个笑话所表达的:分析师对少数几件事了解很多,而投资组合经理对很多事情了解一点点。然而,在我看来,风险管理人员对大多数事情了解得最少,因此他们最不适合评估组合风险。
在 12 月的《这次没有什么不同》一文中,我讨论了领先的风险建模工具——“风险价值”(VaR),它为投资组合提供“最坏情况”的风险估计。我提到,在该模型被采用后的头九年里,其预测的最大交易亏损从未被突破。然后,在 2007 年第三季度,这一预测在四分之一的交易日里被突破。显然,这个模型被证明并不完全可靠。模型可能存在缺陷,其依据的历史数据可能不具代表性或不充分,或者世界已经发生变化。无论原因如何,VaR 失败了。
I’ve long been critical of risk management as a distinct investment discipline. Now, a convincing case for my view can be made on the basis of prima facie evidence: The fact that most financial institutions appointed risk managers after the collapse of Long-Term Capital Management in 1998 doesn’t seem to have helped them avoid the subprime mess. If you trust someone to be expert enough to make an investment, then that’s the person who can best assess its risk. If you trust someone to assemble portfolios, it’s they who can best judge how things will behave in combination. In the isolated risk management function, I feel people who know less about the underlying investments second guess the people who know more. There’s an ongoing dilemma, as expressed in a joke I posted on my bulletin board in 1970, about the fact that analysts know a great deal about a few things, while portfolio managers know a little bit about a lot of things. In my view, however, risk managers know the littlest bit about the most things, so they’re least suited to evaluate portfolio risk. In December’s “No Different this Time,” I included a discussion of the leading risk modeling tool, “value at risk” or VaR, which provides a “worst case” estimate of the risk in a portfolio. I mentioned that in the first nine years after the model was adopted, its predicted maximum trading loss was never exceeded. And then, in the third quarter of 2007, it was exceeded on a quarter of the trading days. So clearly, this model proved to be less than totally reliable. The model may be flawed, the historic data on which it was based may have been non-representative or insufficient, or the world may have changed. Regardless of the reason, VaR failed. T
当你读到高盛如何成功避开 CDO 危机并做空市场(见 12 月 14 日《华尔街日报》),你会发现,这是靠其自营交易部门高管的理性判断做到的。讽刺的是,当抵押贷款相关证券价格刚开始暴跌时,波动率的上升推高了高盛的 VaR 值,迫使他们清掉了那些最终本可带来巨额利润的头寸。据《华尔街日报》报道,“当时持有类似头寸的一位客户……称,他通过接走高盛的[一笔]空头押注赚了 1 亿美元。‘在我看来,[那些交易员]一旦市场开始……就一直在与公司就 VaR 值较劲。’”
When you read about Goldman Sachs’s success in avoiding the CDO turmoil and getting net-short, (see The Wall Street Journal of December 14), you see it was done on the basis of the reasoned judgment of executives on its proprietary trading desk. Ironically, when mortgage-related security prices first began to plummet, the increase in volatility raised Goldman’s VaR, causing the elimination of positions that eventually would have been highly profitable. According to the WSJ, “a client who had similar positions at the time . . . says he made $100 million by relieving Goldman of [a] short bet. ‘It appeared to me that [the traders] constantly fought a VaR battle with the firm once the market started to

“但最终,主观判断被允许凌驾于风险管理科学之上,结果却出奇地好。
有趣的是,许多银行陷入困境,是因为高层主管想要‘效仿高盛’,要求为机构自营账上加大下注。但他们缺少能做出正确判断的人才,转而依赖统计型的风险管理者。他们亏了大把的钱,不少高管和风险经理也因此丢了饭碗。

我在芝加哥大学读研究生的四十年间——很大程度上是受那里诞生的理论启发——量化投资者在投资行业的参与度显著上升。这些人精通统计和计算机建模,擅长处理海量数据,预测投资组合在各种情景下可能的表现。但他们通常对所持组合中的具体证券知之甚少……也不觉得有必要去了解。换句话说,你可以说他们知道一切的价格,却不知道任何东西的价值。
近年来——以及我们在审视的这些过度行为中——量化投资者的队伍扩大到包括刚提到的风险管理人员;投资银行里设计复杂实体并模拟其未来表现的“金融工程师”;单一险种保险公司里评估所承保风险的分析师;以及那些根据数学算法管理投资组合的人,通常是对冲基金。但值得注意的是,量化投资者及其计算机模型主要是在外推过去市场成立的模式。他们无法预测这些模式的变化;无法预见到异常时期;因此他们通常高估了历史常态的可靠性。
为了给你一个思考的背景,我再次借用我的朋友里克·凯恩的智慧:“99% 的金融历史都发生在两个标准差之内,”他说,“但一切有趣的事情都发生在两个标准差之外。”换句话说,大多数时候市场遵循正常模式,这时资产定价合理,没什么可做的。但偶尔,市场会脱轨,而正是在这时,大钱赚进或赔出。
现在想想这些量化投资者。他们对正常时期的事物如何运转了如指掌,但当事件发生在远离常态的概率分布尾部——比如实际发现次级抵押贷款的违约率不是 2%,而是这个数字的几倍时——他们的分析就毫无用处了。
Over the forty years since I attended grad school at the University of Chicago – largely inspired by theories originated there – there’s been a pronounced rise in the participation of “quants” in the investment business. These are people who know a lot about statistics and computer modeling. They specialize in manipulating large amounts of data and predicting how portfolios are likely to perform under a variety of scenarios. But usually they don’t know much about the individual securities that make up the portfolios . . . or feel the need to do so. In other words, you might say they know the price of everything and the value of nothing. In recent years – and in the excesses we’re examining – the ranks of quants grew to include the risk managers discussed just above; “financial engineers” at investment banks who structured complex entities and simulated their future performance; analysts at monoline insurers who assessed the risks they were asked to insure; and people who managed portfolios, usually hedge funds, on the basis of mathematical algorithms. However, it should be noted that quants and their computer models primarily extrapolate the patterns that have held true in past markets. They can’t predict changes in those patterns; they can’t anticipate aberrant periods; and thus they generally overestimate the reliability of past norms. To give you a context in which to think about that, I’ll again borrow some wisdom from my friend Ric Kayne: “99% of financial history has taken place within two standard deviations,” he says, “but everything interesting has taken place outside of two standard deviations.” In other words, most of the time markets follow their normal patterns, and when they do, assets are priced reasonably and there isn’t much to do. But on rare occasion, the markets go off the rails, and that’s when big money is made and lost. Now think about the quants. They know all about how things will work if times are normal, but their analysis is of no help when events occur that reside in the far-off, improbable tails of the probability distribution – like when it turns out that 2% isn’t the right default rate for subprime mortgages, and the actual figure is several times that.

One of the great investment books of the 1960s was The Money Game by the pseudonymous Adam Smith. Smith talked about a veteran investor, the Great Winfield, who knew he was falling behind the times but had the answer: “Our trouble is that we are too old for this market. . . . My solution to the current market: kids.” In the last decade or two, everyone hired quantitative whiz kids, and the results were disastrous. Hopefully, the events of the last few years will produce a sea change, in which investors come to rely more on seasoned judgment and less on financial engineers. Greenspan and the Fed

艾伦·格林斯潘引导我们经历了历史上最繁荣、市场涨幅最大的时期之一,并且很有先见之明地说过“……历史对长期低风险溢价之后的局面并不友善”,他值得我们给予很多赞誉。不过,尽管我与这位前美联储主席有些间接的个人联系,我还是得说,他的管理并非完美无缺。(当然,我怀疑他也不会说自己做得完美。)
Alan Greenspan deserves a lot of credit for presiding over one of the greatest periods of prosperity and market gains in our history, and for saying, presciently, “. . . history has not dealt kindly with the aftermath of protracted periods of low risk premiums.” With apologies to my indirect personal connection to the ex-Fed Chairman, I must express my view that his stewardship wasn’t perfect. (Of course, I doubt he’d say it was perfect.)
因为他很少动用“道德高地”来警示市场过热,过度的投机才得以肆意蔓延。比如,他曾对“非理性繁荣”发出警告,引起了广泛关注,但我始终不解,若在 1996 年道指位于 6400 点时他认为有必要警示,为何在 2000 年道指攀至 11700 点高位时,他却对此缄口不言?再者,近些年房价高企、房贷放贷激进,他难道不该发出警告吗?
Because he rarely used his bully pulpit to warn about excesses, advances were permitted to run unchecked. For example, his warning against “irrational exuberance” attracted a lot of attention, but I’ve always wondered why, if he considered it justified in 1996 with the Dow at 6,400, we heard nothing from him on the subject in 2000, when it topped out at 11,700. And mightn’t he have warned in recent years about overheated home prices and aggressive mortgage lending tactics?
他几乎没怎么“撤走酒杯”,也从不主动戳破泡沫。1998 至 1999 年,他本可以推动提高保证金要求,2004 年或 2005 年,他本可以推动抵押贷款改革,但他都没有做,坚持认为除了事后回顾,很难识别泡沫。
He did little to “remove the punchbowl,” or puncture bubbles. He could have pushed for higher margin requirements in 1998-99, or for mortgage reforms in 2004 or 2005, but he didn’t, insisting that it’s difficult to identify bubbles other than in hindsight.
他太像个啦啦队长了,总为市场上涨找理由,而且常常把功劳算在生产率提高的账上。
He was too much of a cheerleader, providing justification for market advances, often on the basis of productivity gains.
2004 年,他劝人们选择可调利率抵押贷款,而不是固定利率贷款,因为前者初始利率总是最低。但他忽略了一个事实:(a)低收入借款人可能没有足够能力应对利率重置为更高水平的风险;(b)当时抵押贷款利率处于几代人以来的低点,这本来是他们锁定利息成本的好时机。想想看,如果如今相当一部分可调利率抵押贷款当初采用固定利率,我们会处于什么境地。
In 2004, he urged people to take out adjustable rate mortgages rather than fixed-rate loans, since they always carry the lowest initial interest rate. But he overlooked the fact that (a) low-income borrowers might be ill-equipped to handle the risk of resets to higher rates, and (b) with mortgage rates at multi-generational lows, that would have been a great time for them to fix their interest cost. Just think where we’d be if a good portion of today’s adjustable-rate mortgages carried fixed rates instead.
为了化解发展道路上的颠簸所带来的负面影响,他下调了利率,却将低利率维持了太久。我在 20 世纪 70 年代末、80 年代初的高通胀时期学到,当人们觉得某项资产每年的升值幅度总能超过资金成本时,投机需求便会出现。最近这十年无疑就是如此。
Having cut interest rates to head off negative ramifications from the bumps in the road, he left them low for too long. I learned in the hyperinflationary late 1970s and early ’80s that when people feel an asset will always appreciate at an annual rate in excess of the cost of money, the result is speculative demand. That certainly was the case this decade.
总体来看,美联储——包括现任伯南克领导的班子——似乎倾向于让经济或市场的上涨充分发展,同时限制下跌。每个人都希望……
In general, it seems the Fed – including the current Bernanke regime – wants to let advances run and limit declines, whether in the economy or the markets. Everyone wants

上涨无人不喜,除了逢低买入的猎手和身陷困境的投资者,几乎没人乐意看到回调。但我怀疑这种态度是否理智。
如果没有亏损,何来收益?如果资本创造得到扶持,而资本毁灭被阻止,自由市场经济又如何能有效配置资本?
事实是,像我们刚刚经历的这类过度行为必须得到纠正——尽管痛苦——若不纠正,它们只会在周期更迭中愈演愈烈。“道德风险”将因此滋生,让人们相信冒险者总能获救,这必然会鼓励更大的冒险行为。
美联储在当前局势下的行动可谓大刀阔斧:
advances and no one – except bargain hunters and investors in distress – relishes pullbacks. But I wonder if that stance makes sense. How can we have gains but not losses? How can a free-market economy allocate capital effectively if capital creation is abetted and capital destruction is prevented? The fact is, excesses like we’ve just seen have to be corrected – painfully – and if they aren’t, they’ll just grow bigger and bigger as the cycles wear on. “Moral hazard” will arise, convincing people that risk takers will always be bailed out, something that’s bound to encourage greater risk taking. The Fed’s actions in the current situation have been dramatic:
9 月,贴现率出人意料地大幅下调 0.5 个百分点;随后,又采取有力措施注入流动性、鼓励银行放贷;1 月 21 日,再罕见地降息 0.75 个百分点,一周后又降 0.5 个百分点。
an unexpectedly large half-point cut in the discount rate in September, strong steps to inject liquidity and encourage borrowing by banks, and an unusual ¾-point rate cut on January 21, followed by another ½ point a week later.
担任美联储主席的二十年里,艾伦·格林斯潘必须应对 1998 年新兴市场危机和长期资本管理公司的崩盘;Y2K 千年虫隐患;2000 至 2002 年的科技股泡沫及更广泛的熊市;9/11 袭击的连锁影响;以及对通缩可能性的担忧。然而他从未一次性降息 0.75 个百分点,也未在短短八天内降息 1.25 个百分点。因此,伯南克的动作显得格外激进。美联储是在试图阻止一场寻常的经济衰退吗?还是预见到了异常严峻的形势,或许由房价前所未有的疲软所驱动?又或者是对金融体系的深层脆弱感到担忧,问题的核心集中在银行和单一险种保险公司身上?
赞誉与批评
In two decades as Fed Chairman, Alan Greenspan was required to deal with the emerging market crisis and meltdown of Long Term Capital Management in 1998; the possibility of a Y2K glitch; the tech stock and broader bear market in 2000-02; the ramifications of the 9/11 attack; and concern over the possibility of deflation. And yet he never cut rates by ¾ point in one step or by 1-¼ points in just eight days. Thus Bernanke’s actions seem extreme. Is the Fed attempting to prevent a normal recession? Does it foresee an unusually serious one, perhaps driven by unprecedented weakness in home prices? Or is it concerned about profound financial system weakness, centered at banks and the monoline insurers? Kudos and Brickbats

我不太愿意点名批评某个人,尤其在他已经因丢掉饭碗而受到惩罚之后,但花旗集团的首席执行官查克·普林斯贡献了一句不幸的名言,这句话简直成了过去几年市场过热的象征。7 月初,他颇有远见地说:“当音乐停止时,就流动性而言,事情会变得复杂。”不幸的是,他又补充道:“但只要音乐还在响,你就得起身跳舞。我们还在跳。”
我认为普林斯的意思是说,即使市场已经过热,一家金融机构也必须参与其中,否则就要冒着把市场份额拱手让给那些愿意参与者的风险。但这正是我的观点。有什么业务是公司不愿意做的吗?有什么利润是公司不愿意追求的吗?有没有比失去市场份额更糟糕的事情?如果去年夏天之前那段疯狂时期选择失去市场份额,那该是多好的事。这样做正是避开债务抵押债券(CDO)灾难的关键。短视主义是当今美国企业界最大的问题之一,当所有竞争对手都在向右转时,它让你很难向左转。但我们的商界领袖应该敢于追求卓越。
I hesitate to single out an individual for criticism, especially after he’s been punished through loss of his job, but CEO Chuck Prince of Citigroup contributed the unfortunate quote that just has to stand as the symbol of the last few years’ excesses. In early July, he showed foresight by saying “when the music stops, in terms of liquidity, things will get complicated.” Unfortunately, he added, “as long as the music is playing, you’ve got to get up and dance. We’re still dancing.” What I think Prince was saying is that even if the market’s overheated, a financial institution has to participate or risk losing market share to those who will. But that’s my point. Is there any business a company won’t do? Is there any profit a company won’t pursue? Might there be something worse than losing market share? What a wonderful thing it would have been to lose market share in the crazy period leading up to last summer. Doing so held the key to avoiding the CDO carnage. Short-termism is one of the greatest problems in U.S. business today, and it makes it tough to go left when all your competitors are going right. But our business leaders should dare to be great.

美国银行首席执行官肯·刘易斯在去年年初赢得了我的尊敬,他说:“我们离回首往事、承认自己干了些蠢事的日子不远了……在一个人人都觉得无往不利、认为这次不一样的时代,我们需要多一点理智。”他说得完全正确。问题是他自己怎么做的。美国银行在第四季度计提了 54 亿美元减值,还剩 120 亿美元的债务抵押债券敞口。这些数字大约是花旗集团的三分之一。这是好事还是坏事?还有谁预见到了即将到来的风暴?
Bank of America CEO Ken Lewis won my respect early last year when he said, “We are close to a time when we’ll look back and say we did some stupid things . . . We need a little more sanity in a period in which everyone feels invincible and thinks this is different.” He was dead right. The question is what he did about it. B of A took a $5.4 billion writedown in the fourth quarter and has $12 billion of CDO exposure left. Those numbers are about a third of Citigroup’s. Is that good or bad? Who else saw what was coming?
吉姆·格兰特在他的通讯《格兰特利率观察家》中对担保债务凭证(CDO)的过度膨胀直言不讳,而且发声时机足够早,让警觉的投资者本可以有所行动。例如,他是最早质疑以下事实的人之一:CDO 背后大部分抵押品的评级低于投资级,然而 CDO 债务的绝大多数却被评为投资级以上。
Jim Grant was very outspoken about CDO excesses in his newsletter, “Grant’s Interest Rate Observer,” and early enough for heedful investors to have done something about it. He was one of the first, for example, to question the fact that most of the collateral behind CDOs was rated below investment grade, and yet a vast majority of CDO debt was rated above investment grade.
凯雷集团的威廉·康威在 2007 年 1 月给凯雷同事的一份备忘录中引起了广泛关注——但或许还不够充分——他在其中写道:众所周知(我希望如此),我们为有限合伙人创造的巨额利润,并非仅仅依靠我们的投资天赋,而在很大程度上得益于一个强劲的市场和大量廉价债务的可得性……坦白说,全球金融体系中的流动性如此充裕,以至于贷款机构(甚至“我们的”贷款机构)正在做出极其冒险的信贷决策……我知道这种流动性环境不可能永远持续……我知道它持续得越久,我们所有人就越会面临利用这种流动性的压力。我也知道它持续得越久,结束时的后果就会越严重。
William Conway of Carlyle Group attracted a lot of attention – but perhaps not all he deserved – for a January 2007 memo to his Carlyle colleagues, in which he wrote: As you all know (I hope), the fabulous profits that we have been able to generate for our limited partners are not solely a function of our investment genius, but have resulted in large part from a great market and the availability of enormous amounts of cheap debt. . . . Frankly, there is so much liquidity in the world financial system, that lenders (even “our” lenders) are making very risky credit decisions. . . . I know that this liquidity environment cannot go on forever. . . . I know that the longer it lasts, the greater the pressures will be on all of us to take advantage of this liquidity. And I know that the longer it lasts, the worse it will be when it ends.
约翰·保尔森去年在其对冲基金中获得了高达 590% 的回报,赢得了当之无愧的名声。他做对了三件事:他识别出了住宅房地产领域的泡沫;他弄清了如何从这些泡沫不可避免的逆转中获利;而且他幸运地把握住了时机——不像其他人那样过早下结论,长时间看似错误后放弃——他在 2005 年转为看跌,并一直坚持到 2006 年事实证明他正确为止。
John Paulson won well-deserved fame for generating returns up to 590% in his hedge funds last year. He did three things well: He recognized the excesses in the residential real estate arena. He figured out how to profit from their inevitable reversal. And he was lucky enough to get the timing right; rather than reach his conclusion earlier, look wrong for a long time and give up – as others did – he turned bearish in 2005 and was able to hold on until events began to prove him right in 2006.
我很高兴地告诉大家,我们客户所在的投资领域——比如养老金、捐赠基金和保险公司——大多没有报告过多参与那些杠杆率极高的机构。
I’m glad to say our clients’ sectors of the investment world – such as pension and endowment funds and insurance companies – generally haven’t reported much participation in the most highly leveraged entities.
高盛迄今在危机中独树一帜,既避开了次贷和债务抵押债券(CDO)的损失,又做空抵押贷款证券,安然渡过难关。雷曼兄弟、瑞士信贷、德意志银行和摩根大通等其他机构,似乎也比竞争对手承受的次贷痛苦要少。
Goldman Sachs has distinguished itself thus far by avoiding subprime and CDO losses, being short mortgage paper and skating through the crisis. Lehman Brothers, Credit Suisse, Deutsche Bank and JP Morgan Chase are other institutions that seem to have signed on for less subprime pain than their competitors.

最后,瑞银首席执行官的一份声明,为近期事件提供了另一个洞见。去年 12 月初,他说:“我们次贷持仓的最终价值……仍然无法估量。”我敬佩他的坦诚,也确信他说得没错。但我心中留下的疑问是,当初那些次贷相关证券的买家,在首次评估这些资产时,是否有可能就已经意识到这一点?
Finally, a statement by the Chief Executive of UBS provided another insight into the recent events. Early last December, he said, “the ultimate value of our subprime holdings . . . remains unknowable.” I admire his candor, and I’m sure he’s right. But the question I’m left with is whether it might have been possible for buyers of subprime-related paper to reach that realization at the time they first evaluated those assets?

责任止于何处?
Where Does the Buck Stop?
在追究投资亏损的最终责任时,我倾向于看向做出这些投资的投资者。有时投资者被不可预见的事件打了个措手不及,有时他们成为不道德甚至犯罪分子的猎物。但通常,如果没有买家过于急切地追求回报、过度信任、在某种程度上未能警惕潜在损失、以及被某种好得难以置信的东西所迷惑,这个过程不可能走得这么远。
每个人都梦想着不承担高风险却能获得回报。但这样的回报在哪里能找到?不在运作正常的市场中——也就是说,在有效市场中找不到。不在杠杆中,杠杆理应是双刃剑,既放大风险也放大收益。不在随大流中,也不在购买那些被广泛吹捧、被毫不质疑地抢购的当下热门产品中。充其量,在那些并非完全有效的市场中,它可能存在于拥有——或者与拥有这一稀缺特质的投资者结盟——那就是个人的技能……卓远的洞察力……阿尔法。
要完全理解超额回报是如何实现的以及为何它如此罕见,你必须掌握“超额收益”这一概念。这是每个人都想要的。它是“经风险调整后的超额回报”:即主动投资者的回报超出同等风险被动投资组合所能获得的回报的部分。要让主动投资行之有效,要让超额收益存在,市场参与者——因此,集体而言,市场——必须犯错。这就是我所理解的“市场无效性”。因此,那些认为超额收益唾手可得的人,却未能问出几个简单的问题:
In affixing ultimate responsibility for losing investments, I tend to look to the investors who made them. Sometimes investors are blind-sided by unforeseeable events, and sometimes they’re preyed upon by unethical or even criminal purveyors. But usually the process couldn’t have gone as far as it did if it wasn’t for buyers who sought return too avidly, trusted too much, failed in some way to be alert to the potential for loss, and fell for something that was too good to be true. Everyone dreams of return without high risk. But where can it be found? Not in markets that are working properly – that is, markets that are efficient. Not in leverage, which should be expected to cut both ways, magnifying both risk as well as return. Not in doing what everyone else is doing, or in buying the product du jour that’s being touted broadly and purchased unquestioningly. At best it can be found, with regard to markets that are less than fully efficient, in possessing – or aligning yourself with investors who possess – that scarce attribute: personal skill . . . superior insight . . . alpha. To fully understand how superior returns are achieved and why they’re rare, you have to grasp the concept of “excess return.” It’s what everyone wants. It’s “superior risk-adjusted return”: the amount by which an active investor’s return exceeds that which can be achieved through a passive portfolio of the same riskiness. For active investing to work and for excess return to exist, market participants – and thus, collectively, the market – have to be making mistakes. That’s how I think of the thing called “market inefficiency.” Thus, people who think excess return is readily available fail to ask a few simple questions:
既然有成千上万的投资者随时准备抢购任何过于便宜的资产,天上掉馅饼的好事怎么还会存在?
卖方为什么愿意以能让我获得超额回报的价格卖出这项资产?我难道真的比对方更了解这项资产吗?
如果这真是笔好买卖,为什么别人没抢先拿下?
经纪人为什么把它推给我(而不是自己留作自营交易)?
还有,如果收益与风险相比显得如此丰厚,我会不会忽略了什么隐藏的风险?
Why should a free lunch exist despite the presence of thousands of investors who’re ready and willing to bid up the price of anything that’s too cheap? Why is the seller of the asset willing to part with it at a price from which it’ll give me an excessive return? Do I really know more about the asset than he does? If it’s such a great proposition, why hasn’t someone else snapped it up? Why is the broker offering it to me (rather than grabbing it for his prop desk)? And if the return appears so generous in proportion to the risk, might I be overlooking some hidden risk?
按这个标准来衡量,CDO 的买家们表现如何呢?我猜他们被告知,购买双 A 级抵押贷款证券比双 A 级公司债券能获得更高的回报,却不需要承担额外的风险(否则加杠杆也不会显得那么安全)。我相信他们听到的解释是,这部分回报来源于市场,而不是凭借什么高超的技巧。
How do the CDO buyers measure up in this regard? I’d guess they were told they could get better returns from a double-A mortgage security than a double-A corporate without any incremental risk (or else leveraging up wouldn’t have seemed so safe). I believe they were told the source of this return would be the market, as opposed to great skill on the

CDO 管理人也是如此。我猜想他们极度依赖评级机构和单一险种保险公司的参与。而这两者都存在缺陷。
他们凭什么相信,收购抵押贷款并打包成 CDO 证券(途中还支付了多道费用),最终收益仍然可观?为何一只合法的双 A 级债券,其收益率应显著高于另一只?为何他们不去多问一问,这个奇迹是通过什么过程实现的?为何他们接受,狭窄的利差能通过杠杆安全地转化为丰厚的回报?为何他们如此信任那些模拟表现、而实际历史记录并不适用的证券?他们是否审视过所依赖的评级机构和保险公司的动机与能力?简言之,他们的怀疑精神是否足够?
许多 CDO 买家根本没有独立评估 CDO 风险的能力,但他们照买不误。他们追逐高经风险调整后的收益,依据承诺回报与评级之间的关系采取行动,最终误入歧途。
这一切的底线在于,市场的主要功能之一是通过把买卖双方聚合在价格上,使回报仅仅合理,从而挤出超额收益。认识到这一点,怀疑精神便成为卓越投资的必备要素。多数投资失败,都源于怀疑精神的匮乏。
part of CDO managers. I imagine they relied heavily on the participation of the rating agencies and monoline insurers. Each of these was flawed. What made them believe that mortgage loans could be bought up and packaged into CDO securities (with multiple fees paid along the way) with the resulting return still excessive? Why should one legitimate double-A significantly out-yield another? Why didn’t they ask more about the process through which this miracle was being accomplished? Why did they accept that narrow spreads could safely be turned into generous returns through leverage? Why did they trust so heavily in the simulated performance of securities for which the existing track record wasn’t applicable? Did they look into the motivation and capabilities of the rating agencies and insurers on which they depended? In short, were they skeptical enough? Many CDO buyers had no independent ability to assess the risks of CDOs. But they bought anyway. They followed their desire for high risk-adjusted returns, took action based on the relationship between promised return and rating, and went astray. The bottom line of all of this is that one of the main functions of markets is to drive out excess return by bringing buyers and sellers together at prices from which the return will be just fair. Realizing that makes skepticism an indispensable ingredient in superior investing. Most investment failures are preceded by a dearth of it. *

我常想起 90 年代初《福布斯》杂志上关于薪酬的那一期。文中援引了一位资深企业董事的话,大意是:“我已经放弃让人们做我让他们做的事了。他们做的是我付钱让他们做的事。”很明显,近年来不当的激励让很多人做错了事。贷款发起人丝毫不关心贷款的长期表现。投资银行家指望在贷款变坏之前就把它们打包转卖。评级机构和评估人——投资者的守护者——却被激励着给出偏高的评级。一些公司(a)被潜在利润引诱,进入那些根本无从了解艰难时期会发生什么的领域,因而(b)承担了自己毫无准备的风险。金融机构则在市场过热时未能抽身而出。我的妻子南希说她比大多数人都更喜欢这份备忘录,因为这个道理太好懂了。“当人们没有任何东西处于风险之中时,”她说,“就不能指望他们去做正确的事。”这场博弈中的参与者,更多人蒙羞而非添彩,损失的规模和普遍性就是明证。然而
I often think back to an early 1990s issue of Forbes on the subject of compensation. It quoted an experienced corporate director as saying something like, “I’ve given up on trying to get people to do what I tell them to do. They do what I pay them to do.” It’s clear that in recent years, improper incentives caused a lot of people to do the wrong thing. Loan originators with nothing riding on the loans’ long-term performance. Investment bankers who expected to package and resell loans before they went bad. Rating agencies and appraisers – the investor’s protectors – incentivized to come in high. Companies that (a) were lured by potential profit into areas where there was no way to understand what would happen in tough times, and thus (b) accepted risks for which they were unprepared. Financial institutions that failed to sit out when the markets became overheated. My wife Nancy says she likes this memo more than most, because the lesson is so easy to understand. “People can’t be counted on to do the right thing,” she said, “when they don’t have anything at risk.” Far more participants in this process covered themselves with dishonor than with distinction, as attested to by the magnitude and ubiquitousness of the losses. But the

当前问题的责任主要落在两个群体身上,而这两个群体的问题都不是什么新鲜事:
blame for the current problems falls primarily on two groups, and there’s nothing new about either:
动机不当的中间商,他们能从自己无需负责的行为中获利,从而被这种获利能力所驱使;以及那些过于轻信回报可以无需承担相应风险就能获得、因而愿意购买自己并不理解之物的买家。
middlemen who were improperly motivated by the ability to profit from actions for which they wouldn’t remain responsible, and buyers who believed too readily that return was available without proportionate risk and thus were willing to buy things they didn’t understand.
流程、判断和品格上的错误,就像过去几年所经历的那些,是无法避免会发生的。我们每个人能做的,就是尽量不去参与其中。
Errors in process, judgment and character like those of the last few years cannot be kept from occurring. All any of us can do is try to avoid joining in. February 20, 2008
