GMO 季度信函 2005 年 10 月 杰里米·格兰瑟姆,董事长 清算之日,或者说不管准备与否,风险溢价即将到来,另附致投资委员会的信函(五) 你唯一需要恐惧的就是恐惧本身之匮乏 2005 年度鲁莽奖 以及他连续第五次获得总统职业生涯定位奖。当更正常的风险溢价回报回归时,其后果将由他的继任者承担(幸运的家伙——这几乎比接替杰克·迈耶在哈佛管理公司还要容易,但还差那么一点)。而格林斯潘可以作为资深政治家,警告他(或她)持续低风险溢价的风险。

我们正接近总统职业周期的第一年尾声,这一年连同第二年通常都是做清理打扫、降低道德风险的时候。股市的正常反应是挣扎前行,而这正是它目前的表现。风险资产在这头两年通常表现特别糟糕,之后在第三年刺激政策推动下表现优异。截至今年 5 月,风险类股票持续表现不佳,尤其是小盘股和高波动性股票。接着,就在我们志得意满之时——因为这正是我们预测并布局的方向——所有风险资产出现了一波凶狠的反弹。这延续了上一季度信函中描述的风险与谨慎之间的拉锯战。但这次,我们在美国市场遭受重创,使得今年迄今风险资产的表现领先于保守资产。

25% 第三季度风险资产反弹的纪录令人印象深刻,因为这已经是在 2003-04 年风险资产相对表现(Relative Performance)已经极端强势的基础上发生的。图表 1 和图表 2 展示了过去 3 年市场波动最大季度中,按市值计算的最具波动性股票以及罗素 2000 指数相对标普 500 指数的表现。实际上,许多风险指标现已达到历史最高水平,这很可能导致平均风险溢价跌至现代史上最低的 15%。

25% The record of this third quarter rally in risk was impressive, given that it came on top of the already extreme 2003-04 Relative Performance strength in risky assets. Exhibits 1 and 2 highlight the last 20% 3 years’ performance in the most volatile quarter of the mar-ket by market cap and also in the Russell 2000, both relative to the S&P 500.

就连格林斯潘先生也感到震惊和畏惧。“历史,”他说道,“告诫我们,对信用风险长期掉以轻心的时期,无一例外都紧跟着逆转,同时伴随风险资产价格下跌。”好吧,他花了一段时间才明白这一点,但均值回归确实存在!最终与主席本人站到同一阵线,这该有多么尴尬。因为,在我看来,他一手制造了这轮行情的大部分燃料,又亲自将其投入火中,所以他此刻流露出的担忧,既为其自身开脱,又希望能在我们 11 月的会议上获得一些部分的解答。就目前而言,我们有一个强烈的直觉:最主要的输入变量就是外推法。

Even Mr. Greenspan was shocked and awed. “History,” 10% he said, “cautions that extended periods of low concern about credit risk have been invariably followed by rever-sal, with an attendant fall in the prices of risky assets.” Well it took him awhile, but mean reversion lives!

也就是说,无论当前状况如何,市场都赋予它 25% 的概率成为永久状态。新兴国家目前显著改善的财政状况——例如 20% 的国民生产总值增长率、储备增加、货币走强、本地通胀温和,以及缺乏金融危机——也被视为永久状态,尽管漫长而痛苦的历史事实恰恰相反。类似的还有相对业绩垃圾债券和权益质量价差:高质量公司与低质量公司之间的盈利能力差距已大幅收窄,就像 1980 年石油危机时那样。如果这种收窄真的是永久性的,那么市盈率差异和收益率利差的收窄就合情合理。有可能高质量公司确实永久失去了它们的盈利溢价,市场是对的。当然,更有可能的是,这个比率在很大程度上以不可预测的方式起起落落,而将当前点——尤其是像现在这样的极端点——外推下去,会得出一个令人痛苦的错误结论。

所有人都认同,美国和全球经济中存在极端失衡,部分原因是我们极度缺乏储蓄、由此积累的个人债务,以及极度严重的贸易逆差——现在已占到国民生产总值的 6%。

That is to say, today’s conditions, whatever they are, are 25% assumed to be permanent. Today’s much improved financial condition of the emerging countries – for example, in 20% terms of GNP growth and improved reserves, currency strength, modest local inflation, and lack of financial 15% crisis – is assumed to be a permanent condition, despite a long and painful history to the contrary. Similarly, with Relative Performance junk bonds and equity quality spreads the difference in 10% profitability between high quality companies and low quality has narrowed materially, as it did back in 1980 in 5% the oil crisis.

让我们来算笔账:多头相信一切都会好起来,到目前为止也确实如此。空头则认为这些失衡迟早会自食其果。历史学家必须认识到:财务状况以及各个层面的信心,都会随时间潮起潮落——尽管存在潜在问题,我们现在的信心水平却处于极度乐观的状态。大概率获利的押注不是外推趋势,而是预期均值会大幅回归。我相信,风险溢价回归正常水平的这一转变,将在未来几年主导投资领域的潮起潮落。

国债收益率。不过,老问题还是时机。我们能就此提供什么见解?首先,总统周期的头两年通常极度厌恶风险,平均而言,股市表现相对较差,高风险股票的回报更是极其糟糕。自 1964 年以来,以波动性(即风险)衡量,风险最高的四分之一市值股票在这两年里的实际平均回报分别为:第一年负 2%,第二年负 4.5%。(这不是相对市场的负 2% 和负 4%,而是实打实的绝对负回报!)其次,在头两年里,价值因素很重要(这与第三年不同),而当前市场估值昂贵,风险最高的那四分之一股票比整体市场还要贵。在第三季度高风险资产获得强劲回报之后,低质量与高质量股票之间的估值差距(见图表 3)已接近其历史低点。

图表 3:高质量 vs 低质量股票估值

一个有趣的问题是,为什么风险溢价如此之低,甚至更广泛地看,为什么它会如此频繁地波动,以及是什么因素在驱动它?我们将在本文中探讨这个问题。

格林斯潘之所以对风险追逐行情感到惊讶,原因之一当然是他持续加息——尽管新奥尔良飓风后也不例外——将利率升至 3.75%,并给世界留下未来几个月还将加息两次至 4.25% 的印象。这将使短期实际收益率在多年后首次接近“正常”水平。

一个有趣的问题是,风险溢价为何如此之低,甚至更宽泛地说,它为何会如此剧烈波动,以及是什么因素在推动它?我们将在本文中回答这一问题。

未来 12 个月内风险溢价扩大的概率至少是 2 比 1,很可能达到 3 比 1。

风险资产可能陷入下跌螺旋

如今,最常被接受的风险定义就是波动性。

昂贵的 我们都同意,一只股票或资产围绕其长期趋势波动的程度是风险的重要组成部分。然而,我们中的一些人也会同意,这是一种不完整的定义,因为它忽略了价值和流动性。

Expensive We can all agree that the degree to which a stock or asset 1.7 class bounces around its long-term trend is an important 1.6 part of risk. Some of us, though, can agree that it is an incomplete definition as it ignores value and liquidity.

衡量风险最流行的技术手段叫做 VAR,即风险价值(value at risk)。它基于对历史价格走势和波动率的分析来估算投资组合发生损失的概率。但 VAR 的使用者会认为,两个波动率相同的市场具有相同的风险,即使一个市盈率仅为 8 倍(1982 年),另一个高达 33 倍(2000 年)。在现实生活中,损失的概率和程度历来与价值,也就是你支付的价格,直接相关,而且很难——即使不是不可能——想象这种情况会不再持续。举例来说,自 1925 年以来,如果你在标普指数的市盈率处于过去十年滚动市盈率最低的五分之一区间时买入,并持有 10 年,你每年平均能获得 10.6% 的实际收益。而在最贵的五分之一区间买入,你只能获得可怜的 0.6% 年化实际收益率。从统计上看,价值显然与遭受失望回报的风险有很大关系。

市场通常倾向于将当前状况外推,而不是假设今天的状况会回归正常,这使得用波动率作为衡量风险的唯一指标的问题更加突出。因此,今天极低的波动率被看作预示着市场在未来很长时间内都将具有低风险。当波动率变得很高时,这一点也同样会被外推。因此,使用 VAR 会导致“适当”的投资组合随着波动率的变化而发生巨幅调整。例如,今天的波动率非常低,在正常波动率下会被视为风险很高的投资组合,如今却被认为是可接受的。

当今风险定义中缺失的第二个重要因素是流动性。市场总是要求为缺乏流动性支付巨额的风险溢价,以此反映在数据变化时快速、廉价地调整投资头寸所需的额外成本和延迟。有充分理由认为,流动性溢价高得离谱,因为没有哪家机构必须在周四下午之前百分百持有现金。但在一个职业生涯风险至关重要、投资者看重自己与群体保持一致能力的现实行为世界中,巨大的流动性溢价确实存在。例如,在美国股票市场,按市值计算流动性最低的四分之一股票,在过去至少 40 年里,其表现每年都超过整体市场超过 1 个百分点。

3 季度信函 – 2005 年 10 月 GMO 市场不时会发生流动性危机,其中国际化投资方面的情况尤为突出。当需要抛售流动性差的头寸时,往往会导致价格极端疲软,而这又进一步引发更多抛售。我们现在所处的世界,对冲基金行业规模已达 1 万亿美元(这还不算它们巨大的杠杆),其交易量至少占每日股票交易总量的 25% 至 30%。有相当可靠的证据表明,对冲基金持有的流动性较差的资产多头头寸多于空头头寸,因为它们试图从风险溢价中获利。我们最大的押注是超配新兴市场股票。我们认为,如果美国市场仅仅是不下跌,新兴市场就很可能出现大幅上涨;年初至今,新兴市场指数已领先标普 500 指数 22%。当然,我们最大的错误是警告投机性、低质量股票存在弱点。

长期资本管理公司的危机就是一个低质量案例。我们的美国策略因非流动性证券的抛售潮在当季损失了 2% 到 3%,此前年内微薄的收益像雪球一样迅速消失,最终产生了可观的年内亏损,主要在 -1% 到 -2% 之间。在国际策略方面,我们从 VaR 模型面临的风险——非流动性和波动性可能相互作用——来看,当季与市场基本持平,大多数策略在年内仍保持领先。我们的新兴市场股票策略在当季勉强录得正收益,年内领先基准约 2%。在美国和国际债券策略中,我们当季表现略好于持平,只有新兴市场债券再次以超过 1% 的优势胜出,年内上涨 4%。

The Long Term Capital crisis was an example of low quality. Our U.S. strategies lost by 2 to 3 percent for what can happen as a wave of selling illiquid issues the quarter and went from modest year-to-date gains to snowballs. substantial year-to-date losses, mainly in the range of -1% to -2%. In international we were about level with the VAR runs the risk that illiquidity and volatility can inter- market in the quarter with most strategies still ahead for act.

资产配置类策略整体表现也不错,其旗舰全球平衡策略本季度上涨超过 1%,全年上涨 3%——实现了连续第六年上涨。对冲策略的回报则表现不一。例如,市场中性策略本季度表现不佳,全年下跌超过 2.5%。均值回归策略和新兴市场债务策略本季度分别上涨超过 3% 和 6%,全年分别上涨超过 8% 和 11%,而多策略本季度仅上涨 0.25%,年初至今上涨 3.25%。——这还远远不够,利率上升也牵涉其中。低利率为更多杠杆提供了合理性,正如低波动率一样。随着利率上升,合理的杠杆水平会收缩,对冲基金杠杆投资组合的抛售就会开始。如果对冲基金持有的是非流动性多头仓位,那么等比例减少多头和空头仓位,将导致流动性较差的资产表现更差,并可能让海龟们开始沿着海滩奔跑。

高杠杆率与利率上升,再加上波动率和 VAR 不断走高,以及流动性溢价和不对称——总之,这是一个艰难的季度,业绩糟糕。——流动性极差的对冲基金投资组合,这是一剂猛药,而且很危险。市场下跌的常规刹车是价值:随着股票和资产下跌,它们变得更便宜,因此更具吸引力。但在我们这个看似将价值视为风险组成部分的新世界里,资产下跌更可能仅仅是变得更加波动,从而被视为风险更高、吸引力下降。

近期判断的成功与失败

今年我们曾警告,美国股市前景看空但并非灾难性,并预计 9 个月内实际回报为零。不过,我们仍足够接近,有望在第四季度优质资产的反弹中相对脱困——我相信这很有可能。

关于房地产市场的更新

4 月份的季度信函中,我们谈到了近乎全球性的房地产泡沫。以澳大利亚和英国作为先行指标,我曾认为美国可能至少还有一年时间,但一些泡沫最严重的市场,如波士顿,应该会像伦敦和悉尼领先其他城市那样,更早见顶。

现在可以清楚地看到,有几个在上涨过程中涨幅最大的美国城市,其房价在月度滚动比较中已持平或下跌。而且,越来越多的城市显示出未售房屋库存上升。我目前(6 个月后)的最佳猜测是,美国平均房价将在大约 6 个月后见顶。作为记录,当英国房价持平后,消费增长确实迅速从一年前的近 +10% 下降至接近零。

新增一桶原油需要 7 年才能流入市场,而要真正完成一项艰巨任务——即便全力推进——也需要 20 到 30 年。卡特里娜飓风对经济的短期影响将远超 9/11,尤其是在能源领域。不过,从全年来看,其经济影响最终会归于微不足道。而它的政治影响,则很可能再次变得极为深远。新奥尔良很可能成为一次政治分水岭事件,可能改变两党在未来数年的相对实力,甚至影响下一届总统大选的结果。如果真是这样,那么卡特里娜的经济后果就可能是巨大且持久的。即便考虑到长期油价的不确定性,要开发这些新资源,仍然需要巨大的勇气和庞大的资金——数以千亿计。当你知道需要 42 美元一桶才能实现回报时,很难投入数十亿资金去面对一个 7 年的投资周期。即使今天油价是 65 美元,你也清楚它可能在 7 年后跌到一半甚至更低。

9/11 事件后不久,我在一份季度信函中写道,以国民生产总值衡量,该事件的直接经济成本可以忽略不计,而且由于会刺激经济刺激措施出台,甚至可能产生正面的长期影响。这个预测在经济后果方面的判断是正确的。但它严重漏判了更重要的方面——政治态度的转变。

综上所述的建议

再次强调,而且要比以往更加坚定:全面降低风险敞口,现在就做。

GMO 季报 —— 2005 年 10 月刊 第 5 页 GMO 专题 2005 年 10 月 杰里米·格兰瑟姆,主席 致投资委员会的信函 V* 投资行业中的看涨偏见

当布什总统把第一任期内就业岗位的增加列为一项政绩时,尽管这实际上是自 1932 年胡佛总统以来四年任期中最小的就业增幅百分比,他不过是展示了美国经济和股市中一个最重要的特征:一种巨大的看涨偏见。传递坏消息在政治中得不到回报,和它在股票经纪或投资管理中得不到回报一样。相比之下,持续的乐观情绪不仅对生意和政治有利,甚至还可能是美国一个重要且常常令人钦佩的特征。然而,对于投资者来说,这却是一个尤其危险的特征,值得我们理解。为此,以下列出了看涨偏见的几个特征。

经纪公司

特别是在牛市形成过程中,我们很希望看到大公司能提供平衡的陈述。不幸的是,经纪业务的结构导致了一种近乎荒谬的看涨偏见。在牛市最后几年里,最大经纪公司的典型广告画面是一只大得几乎塞不满整页的牛。页面底部只够放下两个大字:“看涨。” 同一家公司曾难以容忍其经验丰富的经济学家偶尔发出的看空观点,而这位经济学家的观点恰恰因其独特的中立性而备受尊重。他的继任者很快证明了他的立场所在(或他仅仅是抓住了要点),他在《纽约时报》上发表了一篇文章,文中论证,除其他观点外,90 年代是 20 世纪经济最好的十年,这就是市场理应表现如此出色的原因。作为量化分析师,我们只用了大约两分钟就列出了这十个十年的硬数据。事实上 90 年代表现平平,国民生产总值增长率在十个十年中排第六,生产率排第五,与可怕的 70 年代大致相当。可以说 90 年代和 70 年代打了个平手,丝毫没有体现出文章想要表达的观点。它反而无意中说明了一点:如果你在 1999 年想在一家卖方公司保持良好的地位,你最好对数据做出看涨的解释。它同时还说明了一点:即使是容易证明其数据错误、带有看涨倾向的文章,你也能轻易地在《纽约时报》上发表。

分析师

因此,在最高层面,大公司的整体基调是看涨的。它们的股票分析师以一种现在广为人知的方式反映了这一点:买入评级与卖出评级的比例是 20 比 1。为了获取信息而需要与管理层保持友好关系,在 1995 年之后这段时间里,由于许多公司行为变得更加激进,这一点更加凸显。它们对任何批评性评论都公开表现出敌意,有时甚至远远超出了限制接触高管层的范围。对批评性报告的直接投诉有时会被提交给投资银行的高层管理层,同时附上不那么隐晦的威胁:减少投资银行业务量。就连明星分析师也不愿接到来自 S*nd* W**ll 这种人物的愤怒电话!确实有好几位发表负面评论的分析师被解雇了,投资银行业务有时也被重新调整。或许并不令人意外的是,那些如今被抓现行的公司,正是一些最恶劣的霸凌者。分析师的薪酬有时更多地取决于他们对投行部门的有用性,而不是对客户的有用性。因此,到市场顶峰时,尽管有美国牛市有史以来最清晰的普遍高估证据,却几乎没有严肃的负面批评或严厉高估的警告,这丝毫不令人意外。

更根本的问题是,分析师工作中广泛使用的严谨估值模型发生了什么变化?足以说明的是,推荐建议越来越多地基于对盈利增长的短期展望——在有盈利数据可用的情况下。对于许多没有盈利信息的公司,他们不得不依赖销售增长来凑数。

收入中的“几乎所有项目之前的利润”。1070 只股票中,除 7 只外,安然公司就是一个缺乏统计严谨性的生动例子,其市盈率曾跌破 17.5 倍。当有人问及,当你被欺骗时这很难,尽管少数对冲基金分析师确有动力去探寻真相,而市场倍数,即使在 1929 年也从未超过 21 倍,却升至 33 倍的新高。这个问题确实揪出了一些真相。对冲基金经理吉姆·查诺斯(Jim Chanos)根据脚注和悬而未决的问题对安然发出了警告。但这需要真正地去挖掘数据并进行真实的研究,缺乏这种研究固然可惜,但并非重点。我们在 GMO 的量化部门相信了安然编造的一切。我们将严重夸大的收益数据输入股息贴现模型——该模型长期记录良好,正确率高于错误率——答案是,在 2000 年 3 月,安然的定价是前 1000 家蓝筹股平均价值的 5 倍多。(而这个平均价值本身已是公允价值的 2 倍多。)听到分析师们在参议院小组委员会上为他们对安然的推荐辩护,理由是他们也受到了欺骗,这令人非常恼火。价值根本就没有被纳入考量。

到此为止,这是一个直白的故事;1999 年,99% 的全职专业人士相信了保证熊市会到来的数据。如果我们问一下,有多少客户知道 1999 年这些公司普遍存在的看跌观点,那么这个故事的直白程度就不那么直白了(我不太想说扭曲)。大型公司广为宣传的观点,往往不代表真正做实际工作的“工程师”们的看法,而这种分歧似乎构成了我们行业中最严重的信任背弃之一。

But that required real at 1-week training programs.

到市场顶部时,几乎每个行业分析师、以行业股票为基准的投资经理,都几乎总是被预期会给出正面推荐——无论该行业整体定价水平有多高。这主要是基于动量行事。股价、利润率或销售额在上涨的股票都是好股票,无论其价格如何。

同样的动量与外推原则也主导了整体市场建议。凯恩斯的建议是,如果你在乎自己的投资饭碗,就永远、永远不要在定价上犯错。这一点显然尤其适用于在持续膨胀的泡沫中给出看空建议。加里·布林森在 1998 年和 1999 年给出出色建议(即与我的看法一致),结果在距离市场见顶不到一个月时被瑞银解雇。他也是个硬骨头,如果说有谁能逃过此劫,那就是他了。

如果 GNP 和不受欢迎的建议能起作用,他确实可以做到。他的失败让我相信,如果生产率看起来有望上升,那么市场就会被描述为有吸引力且可能上涨。没有哪家对股东负有季度报告责任的大型上市企业能够承受在这种情况下因业务大幅短期损失带来的痛苦。这仅仅可以被视为典型的机构惯性,只不过这些策略师还称美国股市“便宜”——这显然是对价值的陈述。市场被认为“合理”,即便是在虚增盈利的 33 倍市盈率水平上。作为后记,在 2003 年初,这位主要策略师毫不让步,补充道:“我的记录说明了一切。”

GMO 拥有一个巨大优势,即它是一家独立机构。当多数观点强烈看涨时,这些公司必须避免通过自己看涨而与群体明显割裂。

那次我觉得她对了一次!伯克希尔是私营公司,但我们也支付了高价,不过至少我没被炒鱿鱼。我们在 2.5 年内损失了 45% 的承保业务——原因是分析师们看空,但老板们却不这么看。我们出于正确的理由做出了正确的押注来降低风险,并赢得了这些押注,但丢掉的业务却比任何竞争对手都多。面对这些对看空态度的回应,回到蜂巢里,那些工蜂——也就是大投行里的底层分析师和基金经理——实际上相信什么?在这个话题上,我掌握一些不寻常且具有揭示意义的数据。从 1997 年到 2001 年的 4 年间,我向超过 1000 名全职专业股票分析师和基金经理提出了几个简单的调查问题。关键问题是要弄清他们中有多少人相信标普 500 指数的市盈率会在未来 10 年内某时回到 17.5 倍以下。人性就是随大流:智人学会了在狩猎中合作,而那些独自行动的个体更容易饿死或被杀害。

2000 年的巨型泡沫与 1929 年和 1965 年的牛市不同,区别在于股票持有的广度。

1929 年,只有 10% 的家庭持有股票,到 1965 年也只有 25%。而到了 2000 年,一半的家庭都持有股票,因此严肃杂志的读者几乎全是股东。与此同时,对股票节目感兴趣的电视观众规模也变得足够大,足以支撑大幅扩展的节目内容。结果,你连在当地油腻小饭馆吃个午饭,都会发现周围人聊的不是足球比赛,而是股票行情。

规模本身,与公司高管的收入高度相关。在这种回报激励下,操纵利润和夸大收益——既通过驱使会计师操作,也通过推动会计准则的放宽——变得极为普遍,因为这样做能带来巨额回报。

这种看涨倾向在企业固定收益养老金计划所使用的假设中尤为明显。到 1999 年泡沫时期,它们的回报假设已经达到了“道琼斯指数 36,000 点”的荒诞程度。

印刷媒体——除少数值得尊敬的例外——几乎一边倒地看涨,而股票的广泛持有使得大量看涨宣传得以形成足够的影响力。但将媒体的普遍看涨倾向归咎于它们并不公平,因为它们的职责不是教育或警示公众。它们的工作描述首要任务是销售杂志或吸引观众,而 1996 年至 2000 年间,观众想读想看的内容越来越明显:“10 只电信牛股”、“如何在 55 岁时比你想象的更富有地退休”、“道琼斯指数 36,000 点”。

With these rewards, manipulation overwhelmingly bullish, and the breadth of stock and overstatement of earnings – effected by pushing ownership allowed a critical mass of bullish propaganda accountants as well as pushing accounting standards – to be formed. But it is not fair to blame the media for stand to be hugely rewarded and are therefore very their generally bullish bias, for they are not paid to common. educate or warn. Their job description is primarily to sell magazines or attract viewers, and it was increasingly The bullish bias was particularly evident in the obvious from 1996 to 2000 what the audience wanted to assumptions used by corporate defined benefit pension read and hear: “10 Great Telecom Stocks,” “How to retire plans. By the ‘99 bubble their return assumptions had at 55 richer than you thought,” “Dow 36,000.”

看涨情绪已使标普 500 指数的平均收益率升至 9.5% 以上,尽管债券市场的确能带来可验证的销售增长。这是他们的借口——当债券收益率降至 5% 而市盈率升至 33 倍时,暗示这还是个不错的理由。但投资行业截然相反,股票的收益率只有 3%。(如果企业将全部利润按 33 倍市盈率派发股息,就会得到 3% 的股息率。)利用不切实际的乐观假设,养老金得以暂时“休假”——停止缴款,而它们日后将迫切需求这些缴款,并导致此后数年的收益被夸大约 10%。商业或政治压力要求持续发布极端看涨的观点,即便内部人士可能实际上更偏空——即使是在当前长期国债收益率 4.5%、股票收益率不到 5.5% 的情况下也是如此。

Bullish risen to an average of over 9½% even as the bond market covers provably increase sales. That’s their excuse and had fallen to 5% and P/Es had risen to 33x, implying an it’s a good one. But the investment industry, in contrast, earnings yield to stocks of 3%. (Stocks would have a 3% is paid to give its best fiduciary advice, and its bullish yield, for example, if corporations paid out all their bias clearly interferes with doing that. earnings at 33x earnings.) Using unrealistically optimistic assumptions allowed pensions to take a Summary ‘holiday’ from contributions that they would later desperately need, and resulted in earnings being about The commercial or political imperative to deliver 10% overstated for several years. Even today, with long relentlessly bullish opinion is extreme, even when bonds at 4½% and the earnings yield at under 5½%, the insiders may actually feel more bearish.

更糟的是,长期养老金回报假设仍显示乐观偏见超过 8%!我们大多数人似乎天生就轻信;相信权威知道自己在做什么,并且多数共识观点应该被采纳。我们也倾向于夸大那些经常重复的建议的重要性,一旦某个观点被接受为自有看法,就对其过度自信,不愿改变。在接受建议之前,尤其是在牛市中,你应当时刻提醒自己该行业的乐观偏见和既得利益,并始终提出质疑。

作为衡量所有乐观偏见的底线指标,我们可以观察净收益与"特殊项目"后经营收益之间的差距。在一个无偏的世界里,例如,当你出售一个部门时,从出售折旧过低的资产中获得令人愉快的账面收益的频率,将与面临令人不快的账面减值的频率相当。
