迈克尔·J·莫布森 短期世界中的长期投资:心理与激励机制如何塑造投资行业
Michael J. Mauboussin Long-Term Investing in a Short-Term World How Psychology and Incentives Shape the Investment Industry
当我们因那些几乎不为人察觉的行动而改善了长期竞争地位时,我们将这种现象称为“加宽护城河”。如果我们希望十年或二十年后能拥有我们想要的那种企业,这一点至关重要。当然,我们总是希望在短期内赚更多的钱。但当短期与长期发生冲突时,加宽护城河必须优先。如果管理层为了达到短期盈利目标而做出糟糕的决定,那么无论后续如何绝妙操作,都无法挽回已造成的损失。
When our long-term competitive position improves as a result of . . . almost unnoticeable actions, we describe the phenomenon as “widening the moat.” And doing that is essential if we are to have the kind of business we want a decade or two from now. We always, of course, hope to earn more money in the short-term. But when short-term and long-term conflict, widening the moat must take precedence. If a management makes bad decisions in order to hit short-term earnings targets . . . no amount of subsequent brilliance will overcome the damage that has been inflicted.

华尔街有一种倾向,就是过分强调短期利益,不惜牺牲长期利益……市场会奖励那些追求短期行为的人,哪怕这些行为是以损害公司的长期价值为代价。
Wall Street has a tendency to overemphasize short-term benefits at the expense of long-term benefits . . . There is a reward given to pursue short-term actions that provide a short-term benefit at the expense of long-term value to your company.

Short Termism
Short Termism
你随时都能看到这样的场景:棒球迷的心情因为漫长赛季中连续十场比赛的表现而起伏;投资经理因为一个季度的业绩被捧上天或踩到地;投资者在财报发布后疯狂抛售或欢天喜地买入一只股票。这些情景有个共同点——过度关注短期结果。在任何一种情况下,紧盯短期都会阻碍理性的长期决策和判断力。
You see it all the time: a baseball fan’s mood rises or falls based on a ten-game stretch in a long season; an investment manager is heralded or derided for a quarter’s results; investors dump, or euphorically buy, a stock after an earnings release. These scenarios share a common feature—a heavy focus on short-term results. In every case, a short-term emphasis can hinder intelligent long-term decisions and perspective.
对短视主义的哀叹来自四面八方,但似乎没有任何个人或团体能够阻止其不可抗拒的拉力。然而,短期思维的泛滥既带来了挑战,也创造了机遇。那些能在适当条件下以长期视角思考和行动的人,有望从他人的短视中获益。
Laments about short termism come from many quarters, yet no person or group appears able to stop its inexorable pull. But the swell in short-term thinking presents an opportunity as well as a challenge. Individuals who can, under the proper conditions, think and act with a long-term perspective stand to benefit from the short-term focus of others.
公司、投资者和投资经理是导致资本市场短期主义的主要参与者。这些群体之间的互动、他们各自通常相互冲突的激励因素,以及当今汹涌的信息洪流,共同塑造了市场行为。
Companies, investors, and investment managers are the main actors involved in capital markets short termism. The interaction between these groups, their respective and often conflicting incentives, and today’s information torrent all combine to shape behavior.
The Causes …
The Causes . . .
在讨论如何利用短期主义之前,有必要先探讨一下,为什么目光短浅的观点如今如此盛行。这么做,我们可以指出至少四个来源,它们之间并非互斥:
Before discussing how to take advantage of short termism, it’s worth discussing why a myopic view is so prevalent today. Doing so, we can point to at least four sources, which are not mutually exclusive:

激励机制。个体对激励机制做出反应,是经济学中最有力的法则之一。近几十年来,三项显著变化改变了激励机制,助长了短视倾向。其一,许多公司重新设计了高管薪酬。其二,投资者越来越多地将投资决策外包给外部顾问,而非自行决策。最后,许多投资公司将其所有权结构从合伙制转变为金融集团。
Incentives. That individuals respond to incentives is one of the most powerful lessons in economics. In recent decades, three noteworthy changes shifted incentives, encouraging a short-term focus. First, many companies revamped executive compensation. Second, investors increasingly outsourced investment decisions to external advisors, instead of making the decisions themselves. Finally, many investment firms changed their ownership structure from partnerships to financial conglomerates.
我们将详细讨论这些激励机制的转变,观察它们如何引发了行为上的变化。同时,公司、投资者和投资经理之间的持续互动意味着,一个群体的行为变化能够——而且经常确实——影响到其他群体。
We will discuss these incentive shifts in detail to observe how they prompted a change in behavior. Also, the continuous interaction of companies, investors, and investment managers means that one group’s behavioral change can, and often does, affect the others.
心理学。一条引人入胜且颇具相关性的研究线索,探讨的是压力带来的效应。对大多数动物而言,躯体威胁会触发压力反应。如果威胁过去或消失,动物便会回归平衡状态。人类通常面对的是心理压力,但我们仍会通过加快心跳、释放肾上腺素、增强感官灵敏度、关闭消化、生殖和免疫系统等长期运转功能,做出躯体上的回应。人类的问题在于:心理压力往往是慢性的。其结果是,身体每天都会发现自己处于危机之中。压力的典型症状——高血压、生殖问题和频繁患病——反映的正是这种主要发生在人类身上的状况。
Psychology. A fascinating and relevant line of research addresses the effects of stress. For most animals, physical threats trigger the stress response. If and when the threat passes, the animal settles back to a balanced state. Humans generally face psychological stress, though we still respond physically by pumping blood, releasing adrenaline, sharpening senses, shutting down long-term operations like digestion, reproduction, and the immune system. The problem for humans: psychological stress is often chronic. As a result, the body finds itself in crisis every day. Stress’s normal symptoms—high blood pressure, reproductive problems, and frequent illness— reflect this mostly-human condition.
此外,压力会让你只顾眼前,忽视长远。就像被狮子追着跑时,谁还有心思担心下周的事——同理,如果业绩差三个月就可能被炒鱿鱼,谁还会去考虑三年的投资回报。高度紧张的状态无疑会助长短视思维。
Moreover, stress mobilizes you for the short term and ignores the long term. Just as there’s no use worrying about next week if a lion is chasing you, there’s no need to consider three-year investment returns if you’re likely to get fired for poor three-month results. 3 Heightened stress undoubtedly encourages a short-term mindset.
当人们本意要做出好的决策,却落入了某些决策陷阱时,心理学也发挥了作用。这些陷阱包括可得性偏差、近因偏差和损失厌恶。我们将指出这些偏差是如何削弱每一类群体的决策能力的。
Psychology also comes into play when individuals intend to make good decisions but fall prey to certain decision-making pitfalls, including the availability bias, the recency bias, and loss aversion. We will point out how these biases undermine the decision making of each group.
信息。媒体、公司及财务顾问每天都会倾泻出海量的信息。投资者自然需要信息来做出决策。但投资者还必须区分开噪音与信号,这是一个关键判断。
Information. The media, companies, and financial advisors churn out an extraordinary amount of information every day. Naturally, an investor requires information to make decisions. But investors must also make a crucial distinction between noise and signal.
试想一个抛硬币的比喻。假设这是一枚公平的硬币,长期来看,正面和反面出现的比例会趋向于一半对一半——这个规律随着重复试验次数的增多才会显现出来。然而,在短期的一系列抛掷中,正面和反面的比例可能远远偏离五五开。那些在噪音领域里操作的投资者,很难做出理性的长期判断。
Consider the metaphor of a series of coin tosses. Assuming a fair coin, the long-term signal is an evenly-split ratio between heads and tails, revealing itself with repeated trials. However, a short series of tosses may show a ratio vastly different than fifty-fifty. Investors operating in the realm of noise have a hard time making reasoned long-term judgments.
媒体、华尔街分析师及其他金融评论家,其本职工作就是生产信息。然而,这些信息的绝大多数不过是噪音。正如纳西姆·塔勒布所言:“人们没有意识到,媒体是靠吸引你的注意力来赚取报酬的。对记者而言,沉默几乎从不胜过任何话语。” 4 更多信息制造出更多噪音,也引发市场更多反应,却并未生成洞见或价值。
The media, Wall Street analysts, and other financial pundits are paid to generate information. But the vast majority of it is noise. As Nassim Taleb puts it, “People do not realize that the media is paid to get your attention. For a journalist, silence rarely surpasses any word.” 4 More information creates more noise and more market reaction, without generating insight or value.
变化速度。企业变化速度的明显加快,成了投资期限缩短的最后一个原因。举例来说,过去三十年左右,美国企业的平均资产寿命缩短了三分之一。换句话说,今天的一位首席财务官需要用大约十年时间产生合理的回报率,而他在 1970 年代中期的前任则可以等上十五年。
Rate of change. The apparent acceleration of the rate of change for businesses creates a final source of shorter time horizons. For example, the average asset life in corporate America declined by a third in the last thirty years or so. Said differently, a chief financial officer today needs to generate an appropriate rate of return over roughly ten years, while his mid-1970s predecessor could wait fifteen years.
此外,实证研究表明,美国企业可持续竞争优势的持续时间正在缩短——这一变化并不仅限于科技公司。5 从某个层面看,更短的时间跨度有其合理性,但市场似乎仍充斥着过多不必要的交易活动。
Further, empirical studies suggest U.S. companies face a shrinking period of sustainable competitive advantage—a shift that is not limited to technology companies. 5 On one level a shorter time horizon makes sense, but markets still appear to have too much needless activity.
The Costs …
The Costs . . .
为什么我们要在意这个世界是否变得更加短期导向?首先,更多的活动是有代价的。
Why should we care if the world is more short-term oriented? First, more activity is costly.
研究表明,经济学家常将频繁交易归因于过度自信,而这种行为会导致投资组合回报率降低。由此造成的业绩下降,反映在交易成本和市场冲击成本上。据估算,这些成本对普通共同基金而言平均每年为 70 个基点——对活跃交易者来说更高,对交易不那么频繁的基金则更低。
Research shows that active trading, which economists often attribute to overconfidence, leads to lower portfolio returns. 6 The resulting performance degradation reflects transaction and market impact costs. Estimates suggest these costs are 70 basis points a year for the average mutual fund—with a higher total for active traders and a lower amount for less active funds. 7
接下来,在投资这类概率性领域中,短期视野无法捕捉到系统的真实信号。这好比根据几场比赛的表现来预测一支棒球队的整个赛季战绩。人类天生爱找规律,有充分证据表明,人们倾向于相信一小串数字或结果就能反映更大范围的趋势。心理学家指出,这种认知偏差会导致次优决策。
Next, in a probabilistic field like investing, a short-term focus doesn’t allow you to capture the system’s signal. We can liken this to predicting a baseball team’s full season record based on a sample of a few games. Humans, as natural pattern seekers, have a well-documented tendency to believe that a small series of numbers, or results, reflect the larger series. Psychologists show how this belief leads to suboptimal decisions. 8
最后,那些为了短期业绩而牺牲长期表现的企业管理者,可能会损害自己经营的企业价值。囤货压货就是这种行为的典型例子。20 世纪 80 年代,一些卷烟制造商在提价前向客户大量倾销库存。这额外销量虽然粉饰了短期利润,却牺牲了未来销售,还提前缴纳了消费税、延长了客户付款期限,而且交付给客户的都是不新鲜的产品。⁹ 类似行为至今仍在继续。正如巴菲特在开篇引文中指出的那样,为了达到短期目标而损害企业长期竞争地位的决定,可能会造成不可逆的伤害。
Finally, corporate managers who make decisions to bolster short-term results at the expense of long-term performance risk damaging the value of the businesses they run. Trade loading is a good example of this behavior. In the 1980s some cigarette manufacturers sold excessive inventory to their customers in advance of cigarette price increases. The extra volume goosed short-term earnings but forfeited future sales, accelerated excise tax payments, extended customer payment terms, and provided customers with a stale product. 9 Similar behavior continues today. As Buffett suggests in the opening quotation, decisions to make short-term targets at the expense of a business’s long-term competitive position can inflict irreversible damage.
The Caveats …
The Caveats . . .
继续之前,有两个要点值得关注。首先,市场参与者的短期行为与市场本身的视野是两码事。要理解市场的视野,你得直接去看资产价格。对资产价格的研究表明,市场在今天的价格里已经反映了未来十年甚至更久的现金流。例如,未来五年的预期股息在道琼斯工业平均指数的价值中占比不到 20%。总之,投资者是在对最终属于长期结果的事情做短期押注。
Before continuing, two points merit attention. First, the short-term actions of market participants remain distinct from the horizon of the market itself. To understand the market’s time horizon, you need to look directly at asset prices. Studies of asset prices show the market reflects ten or more years of future cash flows in today’s prices. For example, the expected dividends over the next five years account for less than 20 percent of the value of the Dow Jones Industrial Average. In sum, investors make short-term bets on what are ultimately long-term outcomes.
第二,并非所有市场参与者都应当始终秉持长期导向。确实存在成功的短期投资策略。如果所有投资者都采取长期导向,市场就会失去多样性——而多样性正是市场效率的关键要素。问题出在投资者混淆了目标与策略。太过频繁地,投资者一边怀着追求卓越长期回报的目标,一边却采用植根于短期主义的策略和行为。
Second, not all market participants should be long-term oriented all of the time. Indeed, there are successful short-term investment strategies. And if all investors were long-term oriented, markets would lose diversity—a crucial ingredient in market efficiency. 10 The problem arises when investors confuse their objective with their strategies. Too often, investors mix an objective to deliver superior long-term returns with strategies and behaviors rooted in short termism.
现在我们来谈谈这三类群体,讨论一下他们经历了哪些变化,以及这些变化对缩短时间跨度意味着什么。
We now turn to the three groups, and discuss the changes they have seen and what those changes mean for a shortening time horizon.
Corporations
Corporations
早在上世纪 30 年代,研究人员就指出了职业经理人与企业所有者(即股东)之间潜在的利益冲突。¹¹ 迈克尔·詹森和威廉·麦克林在 1976 年的一篇著名论文中,将代理成本的概念正式化,文中指出:“有充分理由相信,代理人(经理人)并不总会按照委托人(所有者)的最佳利益行事。”¹² 通俗地讲,对高管有利的事,不一定对股东有利。
As early as the 1930s, researchers pointed out potential conflicts of interest between professional business managers and the owners, or shareholders. 11 Michael Jensen and William Meckling formalized the idea of agency costs in a famous 1976 paper, where they noted, “there is good reason to believe that the agent [manager] will not always act in the best interests of the principal [owner].” 12 In plain words, what may be good for the executive may not be good for the shareholders.
尽管这个话题经常出现在今天的头版头条,但首席执行官财富与股东财富之间的巨大鸿沟绝非什么新鲜事。1990 年,詹森和凯文·墨菲写道:“我们对跨越五个十年的三个样本中超过 2000 位首席执行官进行的绩效薪酬与高管激励分析表明,CEO 财富与股东财富之间的关系微弱,且在最近 50 年里已下降了一个数量级。”13
Though it often appears in today’s headlines, the chasm between CEO wealth and shareholder wealth is by no means a new topic. In 1990, Jensen and Kevin Murphy wrote, “Our analysis of performance pay and top-management incentives for more than 2,000 CEOs in three samples spanning five decades indicates that the relation between CEO wealth and shareholder wealth is small and has fallen by an order of magnitude in the last 50 years.” 13
20 世纪 80 年代,人们对代理成本的担忧有所减轻,因为许多观察者认为活跃的公司控制权市场会缓解这些成本。这个活跃的市场还引发了高管薪酬的重大转变:董事会开始将管理层薪酬直接与股价挂钩。图表 1 展示了过去约二十年的这一演变过程。80 年代中期,几乎没有任何 CEO 薪酬与股价挂钩。到了 90 年代中期,受员工股票期权授予的推动,这一比例超过了 40%。如今,大约 60% 的 CEO 薪酬与市场表现相关。
Concerns over agency costs waned somewhat in the 1980s, as many observers believed an active market for corporate control would mitigate these costs. The active market for corporate control also gave rise to a major shift in executive compensation: boards started tying management pay directly to the stock price. Exhibit 1 shows this evolution over the past twenty years or so. In the mid-1980s, virtually no chief executive pay was tied to the stock price. By the mid-1990s, that ratio—fueled by employee stock option grants—surpassed 40 percent. Today, approximately 60 percent of CEO pay is market-related.

由于薪酬与股价表现挂钩,首席执行官们自然而然地追求最大化自身股票价格。在此过程中,许多人因执迷于他们相信能推动价值的单一指标——每股收益增长——而严重偏离正轨。这种执迷持续存在,尽管学术文献中有大量证据表明每股收益增长与价值创造之间的联系相当微弱。
With their paychecks linked to stock price performance, CEOs quite naturally sought to maximize the value of their stock price. Along the way, many of them have gone badly awry by fixating on the single metric they believe drives value: earnings per share growth. This fixation evolved despite voluminous evidence in the academic literature showing the tenuous link between EPS growth and value creation. 14
我们相信,对每股收益增长率的执着源于心理学家所说的可得性偏差(availability bias),即人们倾向于根据广泛可得的信息而非相关信息来做判断。约翰·格雷厄姆(John Graham)、坎贝尔·哈维(Campbell Harvey)和希瓦·拉贾戈帕尔(Shiva Rajgopal)对金融高管所做的一项调查,提供了关于这种对每股收益的激光般聚焦的清醒证据¹⁵。这些高管报告称,“盈利能力自成一类”在财务报告中的相对重要性。他们给出了四个理由:
We believe the focus on EPS growth results from what psychologists call the availability bias, or the tendency to base assessments on widely-available, versus relevant, information. A financial executive survey by John Graham, Campbell Harvey, and Shiva Rajgopal provides sobering evidence of the laser-like focus on EPS. 15 The executives report the relative importance of “earnings are in a class by themselves” for financial reporting. The executives cite four reasons:
1. 投资者需要一个能够概括公司业绩的简单指标。
1. Investors need a simple metric that summarizes corporate performance.
2. 每股收益得到了媒体最广泛的传播和报道。
2. EPS gets the broadest distribution and coverage by the media.
3\. 盯着每股收益能让分析师的工作更轻松。
3. Focus on EPS makes the analyst’s task easier.
4. 分析师们根据一家公司是否能达到市场一致的每股收益预期来评估它的进展。
4. Analysts evaluate a firm’s progress based on whether a company hits consensus EPS.
关注每股收益本身未必是坏事,因为每股收益增长与价值创造显然并非彼此排斥。但一项更令人警觉的调查结果是:近 80% 的高管表示,他们愿意放弃经济价值,来换取平稳的盈利数据。显然,股东无法从这种用会计数据交换长期价值创造的交易中获益。
A focus on EPS may not be bad because EPS growth and value creation are clearly not mutually exclusive. But a more alarming survey finding is that almost 80 percent of the executives said they would give up economic value in exchange for smooth earnings. Clearly, shareholders do not benefit from the trade of accounting results for value creation over the long term.
管理层过分关注每股收益是否是个问题?我们确实这么认为。我们的担忧基于多项研究发现和实际考量。
Is the managerial focus on EPS a problem? We think so. Our concerns are based on a number of research findings and practical considerations.
首先,学术研究表明,在 1990 年代,那些将 CEO 薪酬更紧密地与股票和期权价值挂钩的公司,更多地采用了可自由支配的应计项目来操纵每股收益。研究人员将应计项目定义为经营利润与经营活动现金流之间的差额。虽然研究人员并未否定基于股票的激励措施,但他们得出结论:“基于股价表现的高强度激励,似乎最可能在以下情况下发挥最佳作用:
First, academic research shows companies that tied CEO compensation more closely to the value of the stock and option holdings in the 1990s saw greater use of discretionary accruals to manipulate EPS.16 The researchers define accruals as the difference between earnings and cash flow from operations. While the researchers don’t dismiss stock-based incentives, they conclude that “high-powered incentives based on stock price performance seem likely to work best when
再结合对管理层所享有的自由裁量权——他们通过这种裁量权来利用这些激励措施报告公司业绩——的审慎考量。
coupled with careful consideration of managers’ opportunities to exploit these incentives through the discretion that they enjoy in reporting their firms’ performance.” 16
研究的另一条有价值线索,考察的是公司行为与机构股东构成之间的关系。17 基于二十年的数据,布莱恩·布希将机构投资者归为三类:交易型、准指数型与专注型。(见表 2。)交易型机构换手率高、持股比例小;准指数型换手率低、持股比例小;专注型机构的特征是换手率低且投资仓位大。
Another valuable strand of research examines the relationship between corporate actions and the institutional shareholder base. 17 Based on twenty years of data, Brian Bushee places institutional investors into one of three categories: transient, quasi-indexer, and dedicated. (See Exhibit 2.) Transient institutions have high turnover and small stakes. Quasi-indexers have low turnover and small stakes. Low turnover and large investment stakes characterize dedicated institutions.

Bushee 的分析显示,那些积极从事投资者关系工作的公司(包括频繁发布盈利指引和新闻),会吸引短期投资者。然而,这些投资者一旦看到一连串有利的盈利数据出现断裂,就会迅速抛售。此外,他的研究还表明,短期投资者占比较高的公司,更有可能通过削减研发支出来管理每股收益。
Bushee’s analysis shows that companies with active investor relations efforts, including frequent earnings guidance and news, attract transient investors. These investors, however, are quick to sell when a string of favorable earnings breaks. Further, his research suggests firms with a large percentage of transient investors will more likely manage EPS by cutting research and development spending.
虽然因果关系未必一目了然——是管理每股收益的公司吸引了短线投资者,还是短线投资者迫使公司去管理每股收益——但证据表明,是公司启动了这种反馈循环。在法律要求之外主动增加披露政策,是企业的一种自主选择。布希在总结中建议:“管理层能采取的最重要的一步,或许是拒绝管理(即平滑)报告利润,以此抑制短线投资者的入驻。”
While the causality may not be crystal clear—companies that manage EPS attract transient investors or transient investors compel companies to manage EPS—the evidence suggests companies kick off the feedback loop. Disclosure policies above and beyond legal requirements are a corporate choice. Bushee summarizes by suggesting, “perhaps the most important step that managers could take would be to discourage transient ownership by refusing to manage (that is, smooth) reported earnings.”
尽管与发布盈利指引相关的成本相当高昂,如今仍有三分之二的公司继续这样做。18 虽然人们认为指引能改善沟通,但公司也将波动性降低和同行的参与作为提供预测的理由。
Notwithstanding the substantial costs associated with issuing earnings guidance, two-thirds of companies continue to do so today. 18 While guidance is perceived to enhance communication, companies also point to lower volatility and peer group participation as reasons to offer forecasts.
然而,实证结果与公司管理层的认知并不吻合。麦肯锡公司近期的一项研究并未发现发布业绩指引能带来估值、股东回报或股价波动性的任何改善。进一步地,研究者发现当公司开始发布每股收益指引时,其股票的交易量会随之增加,这与追逐短期利益的交易型投资者兴趣上升的表现相一致。该研究的作者转而主张公司应披露与基础商业价值驱动因素相关的信息。
The empirical results, however, do not square with corporate perception. A recent McKinsey study failed to find any improvement in valuation, shareholder returns, or volatility as a result of guidance. 19 Further, the researchers found when companies start earnings guidance, their stock’s trading volume increases, consistent with elevated interest of transient investors. The study’s authors instead advocate disclosing information that relates to the underlying business value drivers.
学术界还发现,频繁发布盈利指引的公司更有可能为了满足短期盈利目标而牺牲长期增长。这一分析主要聚焦于研发支出的变化。
Academics also found that companies engaging in frequent earnings guidance will more likely sacrifice long-term growth in order to satisfy short-term earnings objectives. This analysis focuses primarily on changes in R&D spending. 20
研究还表明,停止披露每股收益指引的公司,其盈利和股价表现往往较弱。分析认为,业绩不佳更可能是管理层放弃披露指引的动因,而非出于其他“利他”理由。研究结论是:取消指引对股价造成的伤害,更多源于它释放了关于未来财务表现的负面信号,而非取消这一行为本身。
Research also shows companies ceasing EPS guidance tend to have weak earnings and stock price performance. The analysis suggests poor performance more likely motivates managers to give up guidance rather than other “altruistic” reasons. The study concludes elimination of guidance hurts prices more because of a negative signal about future financial performance than because of the guidance cessation itself. 21
最后,近期一项研究显示,在《萨班斯-奥克斯利法案》问世后的世界里,股市对达到或略超市场一致预期每股收益的公司所给予的溢价已经消失。这一发现与以下观点吻合:在 21 世纪初企业丑闻浪潮之后,投资者对那些达到或超出每股收益预期的公司更加持怀疑态度。22
Finally, a recent study shows the stock market premium for companies meeting or slightly beating consensus EPS has vanished in the post-Sarbanes-Oxley world. This finding holds with the view investors are more skeptical of firms meeting or beating EPS estimates subsequent to the wave of corporate scandals in the early 2000s. 22
总之,当今的企业比过去更关注短期。这在一定程度上是合理的,因为全球竞争格局的变化缩短了资产的生命周期。此外,关注短期的公司可能比关注长期的公司更愿意及时面对和处理问题。
In summary, corporations today focus more on the short term than they did in the past. This is partially appropriate, as the shift in the global competitive landscape has reduced asset lives. Further, companies focused on the short term may be willing to face and address problems on a timelier basis than a company focused on the long term. 23
具有讽刺意味的是,当今的许多问题恰恰反映了公司试图最小化代理成本所带来的意外后果。自 20 世纪 80 年代起,企业开始认真认识到为股东创造回报的重要性。其结果是,CEO 薪酬与股价表现挂钩的比例大幅上升。然而,由于可得性偏差的影响,许多管理者非但没有内化股东价值的原则,反而近乎痴迷地专注于每股收益的增长。而那些最关注盈利增长的公司,又吸引了追求短期回报的投资者,这些投资者反过来又要求更多的业绩指引和增长,从而催生了一个不可持续的循环。
Ironically, many of today’s issues reflect unintended consequences of trying to minimize agency costs. Starting earnestly in the 1980s, companies recognized the importance of delivering shareholder returns. The result has been a massive increase in the percentage of CEO pay tied to stock price results. But rather than internalizing the principles of shareholder value, many managers—because of the availability bias—defaulted to a near-messianic focus on EPS growth. 24 The companies most focused on earnings growth attracted transient investors who, in turn, demanded more guidance and growth, fueling an untenable cycle.
Investment Management
Investment Management
公司金融研究者早已认识到代理成本的重要性。
Corporate finance researchers have long recognized the importance of agency costs.
令人意外的是,学术界并未充分认识到投资业务中的代理成本——本质上是金融机构的角色。 25 显然,投资者与投资经理的利益并非完全一致,有证据表明,委托/代理关系对资产定价的影响,超出了标准模型所能捕捉的范围。 26
Surprisingly, academics have not fully recognized agency costs in the investment business— essentially the role of financial institutions. 25 Clearly, the interests of investors and investment managers are not perfectly aligned, and evidence suggests principal/agent relationships have an impact on asset pricing beyond what standard models capture. 26
讨论委托代理问题的缺失,或许反映出该议题相对较新。(见图表 3。)1950 年,个人直接持有的公司股票占比超过 90%。
The dearth of discussion about the delegated agent may reflect the relative recency of the issue. (See Exhibit 3.) In 1950, individuals directly controlled over 90 percent of corporate equities.
如今,个人持有的股票不到 40%,大部分股票由共同基金、养老基金和保险公司持有。责任已经稳步而有力地从委托人转移到了代理人身上。
Today, individuals hold less than 40 percent of equities with the bulk now held by mutual funds, pension funds, and insurance companies. Responsibility has steadily and forcefully migrated from principal to agent.

这对投资行业的行为和资产定价产生了什么影响?一个合乎逻辑的起点是区分投资专业与投资生意。投资专业致力于为基金股东创造卓越回报,从业者往往倾向长期导向、逆向思维且富有耐心。而投资生意则是为投资公司而非基金持有人聚集资产、创造费用收入。
How has this affected the behavior of the investment industry and asset pricing? A logical place to start is the distinction between the investment profession and business. 27 The investment profession is dedicated to delivering superior results for fund shareholders; practitioners tend to be long-term oriented, contrarian, and patient. The investment business is about gathering assets and generating fees for the investment company as opposed to the fund holders.
在健康经营本身并无过错,这种健康状态确实能确保投资公司有资源支持其专业服务,但当钟摆从专业一端过度摆向商业一端时,冲突就会产生。具体而言,当投资回报的交付退居到为投资公司创造费用之后时,问题就会出现。营销压过了市场。包括杰克·博格尔和大卫·斯文森在内的业界权威人士,都曾有力地论证过这一点。²⁸
While there is nothing wrong with a healthy business, and such health assures the investment firm has the resources to support the profession, conflicts do arise when the pendulum swings too far from the profession toward the business. Specifically, problems occur when delivering investment returns takes a back seat to generating fees for the investment firm. Marketing takes precedence over markets. Industry luminaries, including Jack Bogle and David Swensen, have argued this point forcefully. 28
博格尔用两项证据来表明这一转变对基金持有人的危害。他首先指出,区分一家公司究竟是营销型还是管理型的一个替代指标,就是它们提供的基金数量。博格尔利用富达投资编制的、涵盖 54 家最大投资公司从 1994 年到 2003 年数据(这些公司约占行业资产的 85%)的资料,将基金数量较少的公司与提供大量基金的公司做了整体投资业绩对比。(见图表 4。)他发现,聚焦型公司表现要好得多,而且排名最低的 37 个席位中,有 36 个属于营销导向型组织。
Bogle marshals two pieces of evidence to show the detrimental effects of this shift for fund holders. He starts by noting one proxy for differentiating a marketing firm from a management firm is the number of funds they offer. Using data prepared by Fidelity Investments covering 54 of the largest investment firms (representing about 85 percent of the industry’s assets) from 1994 to 2003, Bogle compared the overall investment performance of the firms with fewer funds versus those with an extensive offering. (See Exhibit 4.) He found the focused firms performed much better, and that 36 of the 37 lowest ranked spots belonged to marketing-oriented organizations.

根据博格尔的分析,投资公司的所有权结构在塑造激励机制方面也起着重要作用。在当今规模最大的 30 家共同基金公司中(按 2005 年底资产管理规模计算),仅有 4 家是私人持有的。其余 26 家中,金融集团持有 19 家,另外 7 家是上市公司。大型金融集团往往更注重创造收益,而私人投资公司则更专注于专业领域。这里的数据也似乎有力地支持了这一观点:业绩最好的基金家族绝大多数是私人持有的,而上市公司则占据了业绩最差的 34 个席位中的 32 个。(见图表 5。)
According to Bogle’s analysis, ownership of investment firms has also been important in shaping incentives. Of the 30 largest mutual fund companies today (based on year-end 2005 assets), only four are private. Of the other 26, financial conglomerates own 19 and the other 7 are publicly held. Large financial conglomerates tend to focus more on generating earnings than do the private investment firms that focus more on the profession. The data here also seem to strongly support this notion: the vast majority of the best-performing fund families were privately held, and public firms sat in 32 of the bottom 34 slots. 29 (See Exhibit 5.)

仔细审视共同基金经理人对激励的反应,便能印证博格尔所提供的更广阔视角。实证研究表明,面临更大短期业绩压力的基金经理人,会更关注短期投资。30 该研究指出,投资者的短期视角导致了投资经理人的短期关注焦点。(见图表 6。)如果确实如此,经理人的短期行为可能会影响股票价格,并促使机构逃避其公司治理责任。
A closer look at how mutual fund managers react to incentives substantiates the broader perspective Bogle provides. Empirical research demonstrates that fund managers who face greater short-term performance pressure focus more on short-horizon investments. 30 The research suggests the short-term perspective of investors causes the investment manager’s short-horizon focus. (See Exhibit 6.) If true, short-term manager behavior may affect stock prices, and encourages institutions to shirk their corporate governance responsibilities.

学术研究同样表明,基金经理会在年底调整其投资组合的风险,以扩大管理资产规模。例如,年轻的基金若在年底落后于市场,往往会变得更加激进。此外,那些大幅跑赢市场的基金,也常常采取更激进的策略,以期在同类基金中取得尽可能高的业绩排名。
Academic research also shows fund managers adjust the risk of their portfolios near the end of the year in order to increase assets under management. For instance, young funds tend to get more aggressive toward the end of the year when lagging the market. Also, funds well ahead of the market often take a more aggressive stance to achieve the highest possible performance ranking versus their peers. 31
资产定价模型通常假设投资者是理性的,或者采用无套利假设来达成市场有效。虽然这两种情况都没有充分考虑代理成本的作用,但引人深思的证据表明,代理人行为可能在资产定价中扮演重要角色。
Asset pricing models generally assume either rational investors or a no-arbitrage assumption to attain market efficiency. While neither case provides fully for the role of agency costs, intriguing evidence suggests agent behavior may play an important role in asset pricing.
一种思路关注的是吸纳了投资者绝大多数资金的金融机构与资产表现之间的关系。数据显示,1980 年至 2000 年间大盘股的超额表现,与大型金融机构的崛起直接吻合。研究人员认为,资产管理行业的构成性转变加大了对大盘股的需求,同时减少了对小盘股的需求,这可能解释了大盘股每年 230 个基点的收益溢价。
One line of thinking follows the relationship between the financial institutions garnering the lion’s share of investor dollars and asset performance. The data show the outperformance of large capitalization stocks from 1980 to 2000 coincides directly with the rise of large financial institutions. The researchers argue the compositional shift in asset management increased the demand for large capitalization stocks and decreased the demand for small capitalization stocks, potentially accounting for 230 basis points of annual return premium for the large cap stocks. 32
当然,2000 年代呈现出一幅截然不同的图景,资产增量中很大一部分流向了对冲基金。据估计,自 2000 年以来,对冲基金的数量翻了一番,同时行业管理的资产规模增加了 1 万亿美元。2000 年代还出现了小盘股表现显著优于大盘股的现象;这种相对收益,无疑也反映了 2000 年大盘股的估值过高。
The 2000s, of course, show a much different picture with much of the incremental asset growth coming in hedge funds. Estimates suggest the number of hedge funds has doubled since 2000, while the industry increased assets under management by $1 trillion. The 2000s have also seen small capitalization stocks sharply outperform large capitalization stocks; this relative gain, no doubt, also reflects the overvaluation of the large cap stocks in 2000.
沿用投资行业结构影响投资结果这一思路,值得注意的是,43% 的对冲基金股票持仓集中在市值 50 亿美元或以下的公司(共同基金这一比例不到 26%),近 60% 的对冲基金资产投向市值 100 亿美元或以下的企业(共同基金为 37%)。对冲基金的崛起,是否像 20 世纪 90 年代的大型投资机构那样,也在扭曲市场?
Keeping with the idea that the structure of the investment industry shapes investment outcomes, it is intriguing to note 43 percent of hedge fund equity holdings are in stocks with market capitalizations of $5 billion or less (versus less than 26 percent for mutual funds) and almost 60 percent of hedge fund assets are in companies with market caps $10 billion or less (compared with 37 percent for mutual funds). 33 Has the rise in hedge funds played a role in distorting the markets, just as the large institutions did in the 1990s?

杰克·博格尔提供的数据可能是投资行业中最令人警醒的统计数据:1983 年至 2003 年,追踪标普 500 指数的指数基金年化回报率为 12.8%,而普通共同基金年均回报率为 10.0%。但与此同时,普通投资者每年仅获得 6.3% 的回报。¹ 这个看似不可能的结果归结于一个关键变量:择时。博格尔的数据指的是平均百分比变化,而非以美元加权的变化。当你考虑到投资者极其倾向于在错误的时间投资错误的标的时,这些数据就开始说得通了。
Jack Bogle provides what may be the most sobering statistic in the investment industry: from 1983-2003, index funds tracking the S&P 500 returned 12.8 percent and the average mutual fund gained 10.0 percent annually. Meanwhile, the average investor only earned 6.3 percent annual returns. 34 This seemingly impossible result is attributable to one crucial variable: market timing. The Bogle data refer to average percentage changes, not dollar-weighted changes. When you consider the extraordinary proclivity for investors to invest in the wrong place at the wrong time, the data start to make sense.
例如,在 2000 年第一季度科技与电信泡沫达到顶峰时,投资者向成长型基金注入了创纪录的 1400 亿美元,同时从价值型基金中撤出了 400 亿美元。在随后的五年里,价值型基金的表现大幅优于成长型基金。
For example, at the height of the technology and telecom bubble in the first quarter of 2000, investors poured a record $140 billion into growth funds while pulling $40 billion out of value funds. In the subsequent five years, value funds substantially outperformed growth funds. 35
长青资本管理公司利用超过二十年的市场数据,将共同基金资金流与估值指标配对,生成买入和卖出信号。高资金流入叠加高估值会触发卖出信号,而大规模资金流出与廉价估值则意味着买入信号。在发出卖出信号后——跨越多种投资风格——该投资策略在此后两年期间的回报平均落后标普 500 指数 490 个基点。买入信号则更为可观,在两年内产生了 870 个基点的超额回报。同样值得关注的是,卖出信号的可靠率接近 80%,而买入信号的准确率超过 90%。
Using over twenty years of market data, Evergreen Capital Management paired mutual fund flows with a valuation measure to generate buy and sell signals. High inflows and high valuation triggers a sell signal, while large outflows and cheap valuations mean buy. Following a sell signal—across various investment styles—the return of the investment strategy underperformed the S&P 500 by an average of 490 basis points over the subsequent two-year period. Buy signals generated an even more impressive 870 basis points of excess returns in two years. As noteworthy, the sell signal was reliable nearly 80 percent of the time, while the buy signal was accurate over 90 percent of the time. 36
投资者为什么会犯这个错误?最可能的解释是近期偏差(recency bias),它指的是个体倾向于根据最近的结果进行外推,而没有充分考虑完整的时间序列或当前环境。这种偏差恰恰定义了市场中最可靠的无效性来源之一。一项跨度二十年的近期学术研究表明,个人投资者的买卖模式构成了一个难以战胜的反向指标。更具体地说,研究人员发现,大量买入行为会带来高于平均水平的短期表现,但在接下来的一年里,回报率却低于市场水平。个人投资者卖出股票的情况,恰恰与此镜像相反。
Why do investors make this mistake? The most likely explanation is the recency bias, which says individuals tend to extrapolate recent outcomes without giving full weight to the full time series or prevailing circumstances. This bias defines one of the most reliable sources of inefficiency in the market. Recent academic research, spanning twenty years of data, shows the buying and selling patterns of individual investors provide a hard-to-beat contrary indicator. More specifically, researchers found heavy buying leads to above-average short-term results and below-market returns in the subsequent year. The mirror image holds true for stocks individuals sell. 37
时间会给出答案,但我们在今天的市场中可以看到近因偏差(recency bias)和有问题的投资者资金流向的证据。(见图表 7。)面向散户投资者的基金正大举涌入过去五年表现良好的板块,而对表现不佳的板块则兴趣寥寥。正如比尔·米勒(Bill Miller)所指出的,“人们想买的是五、六年前就该买入的东西;姑且称之为五年心理周期。”38
Time will tell, but we can see evidence for recency bias and questionable investor flows in today’s markets. (See Exhibit 7.) Funds dedicated to retail investors are seeing strong inflows in the sectors that have done well in the past five years, while interest in the groups that have done poorly is sparse. As Bill Miller noted, “People want to buy today what they should have bought 5 or 6 years ago; call it the 5 year psychological cycle.” 38

利用短期主义
Taking Advantage of Short Termism
现在我们清楚地看到,为什么短期思维在投资中如此盛行。首先,竞争在加速,要求企业更加灵活。其次,心理因素——包括可得性偏差和近因偏差——会助长次优行为。第三,随着高管薪酬的性质和投资行业的结构发生变化,激励机制也随之改变。企业更加痴迷于短期每股收益,常常损害长期价值;一些投资经理则将资产管理规模置于投资业绩之上。最后,交易成本下降了:如今投资者转移资产的摩擦成本比历史上任何时候都低。
Now we have a clear picture of why short-term thinking pervades investing. First, competition is accelerating, requiring companies to be more nimble. Second, psychological factors, including the availability bias and the recency bias, encourage suboptimal behavior. Third, as the nature of executive compensation and the structure of the investment industry have changed, so too have incentives. Companies fixate more on short-term EPS, often to the detriment of long-term value, and some investment managers prioritize asset gathering over investment results. Finally, the cost of activity has dropped: investors can move assets around with less friction today than at any time in the past.
那么,投资者如何利用短期主义呢?一种方法是关注时间套利。时间跨度是任何概率性领域的关键考量因素。在这些系统中,短期结果主要呈现的是噪音——噪音与信号的比率非常高。随着时间的推移,信号会自行显现,噪音与信号的比率会下降。短期投资者大多沉浸在噪音的世界里。
So how can an investor take advantage of short termism? One approach focuses on time arbitrage. Time horizon is a crucial consideration in any probabilistic field. In these systems, short-term results show mostly noise—the noise-to-signal ratio is very high. Over time, the signal reveals itself, and the noise-to-signal ratio drops. Short-term investors dwell mostly in the world of noise.
让我们回到那个简单的抛硬币例子来说明这一点。图表 8 的左侧面板是 20 次抛掷试验的结果,显示其中 35% 的抛掷结果为正面。(我们用随机数生成器模拟出了这些结果)。右侧面板则是该序列中接下来 80 次抛掷的结果,显示在 100 次抛掷中,该比率稳定地非常接近 50%。尽管我们知道长期信号是 50%,但短期噪音仍可能大幅偏离长期信号。
Let’s go back to our simple coin-tossing example to demonstrate this point. Exhibit 8’s left panel is the result of a 20-toss trial, and shows that 35 percent of the tosses came up heads. (We simulated these results with a random number generator). The panel on the right continues with the next 80 tosses in the series, and shows that the ratio settles very close to 50 percent over 100 flips. Even though we know the long-term signal is 50 percent, short-term noise can deviate substantially from long-term signal.

资产价格反映的是一组预期。如果追逐噪音的投资者形成的预期与长期信号不符,就产生了时间套利的机会。这种套利只有在短期视角引发多样性崩溃——关注信号的投资者太少——并且信号随时间推移变得清晰时才会有效。因此,在投资世界中游刃有余的关键考量,最终归结为心理、激励和预期。明智的投资者对这三者保持高度警觉,并利用它们为基金持有者谋利。
Asset prices reflect a set of expectations. 39 If investors chasing noise create a set of expectations inconsistent with the long-term signal, an opportunity for time arbitrage arises. This arbitrage works only if the short-term focus creates a diversity breakdown—too few investors focused on the signal—and the signal becomes clear over time. So the critical considerations in navigating the investing world distill to psychology, incentives, and expectations. Intelligent investors remain highly aware of all three, and use them for the advantage of their fund holders.
