以下是迈克尔·莫布森在一次演讲中的摘录,面向
Excerpts from a talk given by Michael Mauboussin to the
2020 年 1 月 30 日,格林威治圆桌会议。早上好。今天能和大家聚在一起,我深感荣幸——这些圆桌会议总能促使我梳理自己的思考。今天上午的主题尤其引人入胜,因为它提供了一个机会,来批判性地审视一些常被肤浅理解的议题。
Greenwich Roundtable on January 30, 2020 Good morning. It’s a real pleasure for me to join you today, as these roundtable sessions always prompt me to organize my thoughts on Dan Callahan, CFA important topics. This morning’s theme is a particularly interesting one because it provides an opportunity to critically examine some issues that are often understood superficially.
我需要提一句:15 年前,我第一次参加与经济圆桌会议相关的活动,当时与伟大的经济学家、历史学家兼作家彼得·伯恩斯坦(Peter Bernstein)同台讨论。我当时说,我希望长大后能成为彼得·伯恩斯坦那样的人。15 年过去了,我老了,但并没有长成那样!
I should mention that I first participated in a session with the Roundtable 15 years ago, and was on a panel with the great economist, historian, and author, Peter Bernstein. I said then that I wanted to grow up to be like Peter Bernstein. Fifteen years later, I have aged but I have not grown up!
我来澄清四个谬误或者说流行的错觉:
I will address four myths or popular delusions:
第一个问题与短视主义有关。你经常听到人们对短视主义的有害影响忧心忡忡,却没有多少具体证据证明它确实存在。我们将批判性地审视一些相关论点,看看它们是否站得住脚。
The first one relates to short-termism. You hear a lot of fretting about the deleterious impact of short-termism, without a lot of concrete evidence for its existence. We’ll critically examine some of the arguments to see if they hold water;
第二个观点是,股息在长期股权回报中扮演重要角色。我将证明,股价上涨是唯一能增加累积资本的投资回报来源;
The second is the idea that dividends play a large role in equity returns over time. I will demonstrate that price appreciation is the only source of investment return that increases accumulated capital;
第三是“投资亏损公司是个坏主意”这种观念。这确实可能是个坏主意,但需要更细致地加以区分。
Third is the notion that investing in money-losing companies is a bad idea. It can be a bad idea, but much more nuance is necessary; and
最后一点与这样一种观点有关:指数投资的兴起,反而让主动管理者更容易了。
The final one relates to the idea that the rise of indexing has made it easier to be an active manager.
一、我们先谈第一个话题:短视主义。我们将其定义为一种倾向:做出在短期内看似有利,却牺牲长期更高回报的决策。这种倾向通常表现为两种形式:投资者的短视主义和管理层的短视主义。¹
I. Let’s start with the first topic, that of short-termism. We’ll define it as the tendency to make decisions that appear beneficial in the short term at the expense of decisions that have a higher payoff in the long term. This tends to come in two flavors, investor short-termism and managerial short-termism.1
纵观历史,担忧短视主义的声音比比皆是——我手头就有几十年前的例子。但《哈佛商业评论》一篇文章中的引语,精准捕捉了当下情绪:
It is easy to find concerns about short-termism throughout history—I have examples that go back decades. But a quote from a Harvard Business Review article captures the current mood:
“……短期主义的阴影仍在蔓延——而且情况可能实际上在恶化。其结果是,企业进行长期投资和价值创造的能力削弱,从而损害了广泛的经济增长,并降低了储户的投资回报。”²
“. . . the shadow of short-termism has continued to advance—and the situation may actually be getting worse. As a result, companies are less able to invest and build value for the long term, undermining broad economic growth and lowering returns on investment for savers.”2
我们来从三个方面来看这个问题。第一个是,为什么经济现实本身可能完全有理由缩短时间跨度。例如,看看新技术的普及速度:电话用了 71 年才让一半美国人口用上,彩电用了 18 年,互联网接入只用了 10 年。随着这些普及速度加快,变化本身也在加速。
Let’s look at three aspects of this. The first is why some shortening of time horizon may be fully justified by the economic facts. For example, consider the rate of diffusion of new technologies: it took 71 years for one-half of the U.S. population to get a telephone, 18 years for a color television, and 10 years for internet access. As these diffusions speed up, so does change. 3
另一个因素是资产寿命。科技公司的资产寿命通常为 6-7 年,而能源和材料公司的资产寿命大约为 17-18 年。过去 30 年间,随着经济和股市的构成从重资产行业转向轻资产行业,平均资产寿命已经缩短。此外,按瑞士信贷 HOLT 的计算方法,治理分数在资产寿命最长的行业最高,在资产寿命最短的行业最低。
Another is asset lives. The asset lives for technology companies are generally 6-7 years, whereas asset lives for energy and materials companies are roughly 17-18 years. As the composition of the economy and the stock market have shifted away from asset-heavy to asset-light industries over the past 30 years, the average asset life has shrunk. Further, it turns out that governance scores, as calculated by Credit Suisse HOLT, are highest for industries with the longest asset lives and lowest for businesses with the shortest asset lives.
评估市场短视行为最根本的方法,是直接观察资产价格本身。你不难找到那些声称股市被高估的权威人士,而这一观点也有证据支持,比如 CAPE 比率。⁴
The most fundamental way to assess the market’s short-termism is to look at asset prices themselves. It is easy to find pundits who suggest the stock market is overvalued, and this notion is backed by evidence such as the CAPE ratio.4
仅凭这一点,那些主张短期主义的人就该三思了:高估值意味着市场正在认可并为之买单的,是未来多年的现金流。这与短期主义恰恰相反。
That alone should give some pause to those arguing for short-termism: high valuations mean the market is recognizing and paying for cash flows many years into the future. It’s the very opposite of short-termism.
我在哥伦比亚商学院上课时,会用一个简单练习来说明这点。我挑出道琼斯工业平均指数中的 5 只股票,按 Value Line 的预估(见表 1),计算它们未来 5 年预期派发的股息现值。这个现值只占当前股票价值的 11%,也就是说超过 90% 的价值来自 5 年之后的现金流。就算把与股息规模相当的回购也算进去,这个比例也只能到 20% 左右。换言之,绝大部分价值都体现在长期现金流中。
Here’s a simple exercise I do with my students at Columbia Business School to make this point. I take five stocks from the Dow Jones Industrial Average and calculate the present value of the dividends they are expected to pay over the next 5 years, according to estimates by Value Line (see exhibit 1). That value represents only 11 percent of the prevailing equity value, which means that more than 90 percent is for cash flows beyond 5 years. Assume buybacks that are as large as dividends and you still only get to about 20 percent. In other words, most of the value is reflected in long-term cash flows.

关于短期主义最流行的论据或许来自资金管理人的持仓周期。以竞争战略研究闻名的迈克尔·波特教授曾指出:“股票的平均持有期已从 1960 年的七年以上,降至如今的约两年……这或许是最能说明投资者视野缩短的证据。”
Perhaps the most popular argument for short-termism is the holding period of money managers. For example, Michael Porter, a professor known for his work on competitive strategy, noted that “the average holding period of stocks has declined from over seven years in 1960 to about two years today . . . it is perhaps the most telling evidence of shortening investor horizons.”5
波特说得确实没错:投资组合的换手率在 1950 年代和 1960 年代要比近年来低得多。不过你可能会问,这是为什么。
Porter is indeed correct: portfolio turnover was much lower in the 1950s and 1960s than in recent times. 6 But you might ask why that is.
一张投资组合换手率的长期图表显示,从 1975 年 5 月 1 日起出现了一个急剧上升(见图表 2)。那一天,股票交易佣金被解除了管制。为了让你对当时的情况有个概念,交易 1 万股每股 40 美元的股票,成本是每股 0.43 美元。而且,买卖价差当然是用八分之一美元来标示的。
A long-term chart of portfolio turnover shows a spike starting on May 1, 1975 (see exhibit 2). That was the day commissions on stock trading were deregulated. To give you some sense of the situation, the cost of trading 10,000 shares of a $40 stock was $0.43 per share. And, of course, bid-offer spreads were expressed in eighths.
因此,交易成本要高得多,从而限制了交易活动。
So the cost of trading was vastly higher, hence limiting activity.7

投资组合换手率是一个衡量基金经理买卖基金内资产频率的指标。投资组合换手率的计算方法为:取特定时期内新购入证券总额或售出证券总额中较小的那个数值,除以基金的总资产净值。
Portfolio turnover is a measure of how frequently assets within a fund are bought and sold by the managers. Portfolio turnover is calculated by taking either the total amount of new securities purchased or the amount of securities sold - whichever is less - over a particular period, divided by the total net asset value of the fund.
此外,在过去 20 年里,换手率实际上是在下降的。按资产加权计算的最新换手率为 25% - 30%,是自 20 世纪 70 年代以来的最低水平。⁸ 现在确实存在一些交易频繁的机构,但它们之所以存在,只是因为交易成本大幅下降。例如,指数基金在 1975 年之前因成本原因根本不可行。
Further, turnover is actually down in the last 20 years. The latest reading of asset-weighted turnover is 25-30 percent, the lowest since the 1970s.8 Now there are entities that trade frequently, but they are only around because the cost to trade has come down so much. For example, index funds weren’t viable prior to 1975 because of cost.
同样值得注意的是,像亚马逊(Amazon.com)这样的公司采取了长远视角,并且得到了市场的回报。认为一家已经上市 23 年的公司之所以受追捧,仅仅是因为它“驯化”了股东,这种说法其实并不符合市场短期主义的叙事。
It’s also worth noting companies such as Amazon.com have taken a long-term view and have been rewarded by the market. The idea that a company that has been public for 23 years is loved only because it trained its shareholders doesn’t really fit the narrative of short-termism.9
让我用几个想法来结束这一点。我明白,管理者和投资者都承受着交付短期业绩的压力。我们这些追求长期职业生涯成功的人,也同样感受到短期压力——这是因为长期正是由一个个短期积累而成的。关键在于做正确的事。
Let me finish this point with a couple of thoughts. I recognize that managers and investors feel pressure to deliver short-term results. All of us who seek to have successful long-term careers also feel short-term pressure—and that’s because the long term is an aggregation of short terms. The key is to do the right thing.
第二,投资者持有期限之所以短于股价所反映的现金流年数,是因为投资者在长期结果上下短期赌注。如果你想了解市场的时间跨度,不要去看投资者,也不要和投资者交谈。去看市场本身——市场是所有投资者的共同产物。
Second, the reason investor holding periods are shorter than the number of years of cash flows reflected in stock prices is that investors make short-term bets on long-term outcomes.10 If you want to understand the market’s time horizon, do not look at, or talk to, the investors. Look at the market, which is a product of all investors. 11
二、第二个迷思关乎股息在资本积累中的作用。在与人合著的一篇论文中,彼得·伯恩斯坦写道:“这些数据驳斥了传统观点——即股票大部分收益来自资本增值,而股息收入即便不算无关紧要,也远没有那么重要。”¹² 某大型投资管理公司发布的研究报告更加言之凿凿,宣称:“有些人可能会惊讶地发现,过去一个世纪中,美国股市 90% 的收益来自股息及股息增长。”¹³ 没错,这确实令人惊讶——如果这是真的话。
II. The second myth is about the role of dividends in capital accumulation. In a paper he co-authored, Peter Bernstein wrote, “These data put the lie to the conventional view that equities derive most of their returns from capital appreciation, that income is far less important, if not irrelevant.”12 A large investment management firm put out research that was ever more emphatic, stating, “Some may be surprised to learn that 90 percent of U.S. equity returns over the last century have been delivered by dividends and dividend growth.”13 Yes, that would be surprising—especially if it were true.
让我们退一步来看。我们储蓄或推迟当前消费的原因,是为了积累资本以满足未来的偿付需求,无论是支付孩子的大学教育费用,还是舒适地退休。
Let’s take a step back. The reason we save, or defer current consumption, is to accumulate capital to satisfy future liabilities, whether it’s paying for a child’s college education or retiring comfortably.
当我们讨论整体股市或某只具体股票时,经常提到“股东总回报”(TSR),它假设股息在无摩擦成本的情况下被再投资。计算 TSR 的公式如下:
When we discuss the stock market in general or specific stocks, we often refer to “total shareholder return” (TSR), which assumes that dividends are reinvested with no friction. Here is the equation to calculate TSR:
TSR = g + (1 + g) * d
TSR = g + (1 + g) * d
在这个公式中,g 代表股价上涨率,d 代表股息率。
In this equation, g stands for the stock price appreciation rate and d stands for the dividend yield.
对 TSR 的过度关注可能会引发一些混淆。14
The focus on TSR can lead to a couple of points of confusion.14
首先,几乎没有人能真正获得一只派息股票的总股东回报率(TSR)。要想做到这一点,你必须拥有一个自动股息再投资计划,且不缴纳税款。符合这一条件的人数微乎其微。大多数人会花掉收到的股息,而大多数基金则允许这笔钱直接转化为现金。因此,依赖过去的总股东回报率来规划未来时,必须格外谨慎。
The first is that almost no one earns the TSR for a stock that pays a dividend. In order to do so, you must have an automatic dividend reinvestment plan with zero taxes. The number of people who fall into this camp are de minimis. Most people spend the dividends they receive, and most funds allow the sum simply to go to cash. So one should be very careful relying on past TSRs to plan for the future.
第二个错误观念是认为股息是投资表现的主要驱动因素。实际上,股价上涨才是唯一能让积累资本增值的投资回报来源。
The second is the belief that dividends are the main driver of investment performance. In reality, price appreciation is the only source of investment returns that increases accumulated capital.
要理解这一点,我们先放慢过程。假设你有一支 100 美元的股票,它支付 3 美元的股息。派息那天,你持有的股票价值 97 美元,加上 3 美元股息(实际上股票在除息日会进行除息调整)。只有当你将全部 3 美元再投资买入该股票,使你的总投资恢复到 100 美元时,你才获得总股东回报(TSR)。由此可知,股价上涨才是财富积累的驱动力。
To understand this, let’s slow down the process. Say you have a $100 stock that pays a $3 dividend. The day that dividend is paid, you have a stock worth $97 and a dividend worth $3 (the stock is actually marked down on the ex-dividend date). You earn the TSR only if you reinvest the full $3 into the stock to restore your investment to $100. From there, it is clear that price appreciation is the driver of accumulated wealth.
你的资本积累取决于三个因素:你投入了多少,投资了多长时间,以及价格升值幅度。顺便说一句,关于回购也存在大量混淆,我现在不打算深入展开。
Your capital accumulation is a function of how much you invest, how long you invest, and price appreciation. By the way, there is also massive confusion about share buybacks, which I won’t go into now.
我还要补充一点,关于资产增长与股东总回报(TSR)之间的关系,有非常充分的证据。那些资产快速扩张的公司,往往带来的回报不佳;而资产增长温和、甚至收缩的公司,表现却不错。因此,将资本返还给股东很重要。
I will add that there is very robust evidence about the relationship between asset growth and TSRs. Companies that have grown assets rapidly have tended to deliver poor returns, whereas those that have grown modestly, or even contracted, have done well. So returning capital to shareholders is important.15
最后一点:我刚才讨论的关于股息的大部分内容,都总结在我的导师、合作者兼好友 阿尔·拉帕波特 2006 年发表在《投资组合管理杂志》上的一篇论文中。彼得·伯恩斯坦 读了这篇论文,称之为“大师级作品”,并大声感叹为什么之前没人把这项分析指给他看。伯恩斯坦 在 86 岁高龄时依然保持学习的开放心态!
One last note: much of what I’ve just discussed about dividends is summarized in a paper that was published in the Journal of Portfolio Management in 2006 by my mentor, collaborator, and friend, Al Rappaport. Peter Bernstein read the paper and called it “masterful” and wondered out loud why no one had pointed out this analysis to him before. Bernstein was still open to learning at the age of 86!
三、第三个神话关于亏损的公司。金融学教授、首次公开募股(IPO)领域权威专家杰伊·里特(Jay Ritter)指出,2019 年进行 IPO 的公司中有 74% 处于亏损状态,这与 1999 年互联网泡沫接近顶峰时的水平大致相当。此外,大约 40% 的上市公司
III. The third myth is about companies that lose money. Jay Ritter, a professor of finance and a leading authority on initial public offerings (IPO’s), reports that 74 percent of companies that did an IPO in 2019 lost money, which is about where the level was in 1999, near the peak of the dot-com bubble.16 Further, about 40 percent of listed
美国公司正在亏损——这一切都发生在实体经济稳健的背景下。17 这意味着市场已经重回泡沫状态——而 WeWork 的传奇故事无疑是火上浇油。
companies in the U.S. lose money—all this against a backdrop of a solid economy.17 The implication is that things have returned to a frothy state—and certainly the saga of WeWork fanned the flames of that narrative.
给你出个小测验:如果我向你提供一家刚在纽约证券交易所上市的公司股票,并且百分之百肯定地告诉你,它在未来 15 年里每年都会产生负自由现金流,你会买吗?
Here’s a short quiz for you: what if I offered you shares of a company just listed on the New York Stock Exchange and told you with absolute certainty it would have negative free cash flow for each of the next 15 years. Would you buy it?
确实有这么一家小公司,名叫沃尔玛百货公司(Wal-Mart Stores, Inc.)。从 1972 年初到 1986 年底,沃尔玛为股东创造的年化总回报率(TSR)为 33%,而同期标普 500 指数只有 11%。投资沃尔玛的投资者,在期末时拥有的资本量,几乎是投资大盘的 16 倍。
Well, there was a little company like that and it was called Wal-Mart Stores, Inc. From the beginning of 1972 through the end of 1986, Walmart generated TSRs of 33 percent versus the S&P 500’s 11 percent. Investors in Walmart would have ended the period with almost 16 times more capital than investors in the broader market.
沃尔玛之所以是一只这么优秀的股票,是因为它的投资回报率非常高。这种情况下,你会希望公司尽可能多地投资——哪怕投资规模超过了盈利,公司必须借助外部资本来做到这一点。
Walmart was such a good stock because it earned a very high return on its investments. In those cases, you want a company to invest as much as it possibly can—even if the investment is larger than earnings and the company has to access external sources of capital to do so.
那么这与现在的情况有什么关系呢?企业的投资形式发生了划时代的转变。1977 年,有形投资是无形投资的 2 倍。如今,无形资产投资已达到有形投资的 1.5 倍(见图表 3)。有形投资会体现在资产负债表中;而无形资产往往作为费用出现在利润表中。
So what does that have to do with what’s going on now? There has been a watershed change in the form in which companies invest. In 1977, tangible investment was 2 times that of intangible investment. Today, intangible investment is 1.5 times tangible investment (see exhibit 3). Tangible investments appear on the balance sheet; intangible assets tend to appear on the income statement as an expense. 18

那么解决方案是什么?如果你想要做苹果对苹果式的比较,就必须把现在计入利润表的投资进行资本化。换句话说,像我们过去那样把它们列入资产负债表。直接的效果就是,利润和账面价值都会上升。19
So what’s the solution? If you want apples-to-apples comparisons, you must capitalize the investments that are now on the income statement. In other words, put them on the balance sheet as we used to. The immediate impact is that earnings and book value both go up.19
这与价值投资者面临的艰难时期有关。价值投资者通常倾向于构建依赖市净率、市盈率等统计因素的资产组合。会计学教授 巴鲁克·列夫 和 阿努普·斯里瓦斯塔瓦 进行了这些调整,发现 40% 至 60% 原本被归类为“价值型”的股票。
This relates to the challenging time for value investors, who tend to build portfolios that rely on statistical factors such as price-to-book and price-to-earnings multiples. Baruch Lev and Anup Srivastava, professors of accounting, made these adjustments and found that 40-60 percent of stocks that had been classified as “value”
或“迷人”换仓类别。此外,他们发现这些调整生成的因素在构建投资组合时信号质量显著提升。²⁰
or “glamour” shift categories. Further, they found that the adjustments lead to factors with much better signals for building portfolios.20
这也回应了关于企业投资不足、将过多资金返还给股东的担忧。如果利润表上的投资分类得当,企业实际上一直在逐步增加其经营性投资。
This also addresses the concern that companies are underinvesting and returning too much money to shareholders. If investments on the income statement are properly categorized, firms have actually been increasing their operating investments over time.
我相信这个迷思为那些愿意卷起袖子真正理解单位经济学的投资者创造了机会。如果你了解沃尔玛每家门店的经济效益有多好,你会站在他们身后鼓掌,看着他们将投资支出超过赚取的收入。同样,如今有些公司虽然亏损,却拥有极具吸引力的经济效益;而另一些公司则是在以传统方式亏损——因为糟糕的商业模式。
I believe this myth has created opportunity for investors who are willing to roll up their sleeves to really understand unit economics.21 If you knew how good Walmart’s store economics were, you would have stood behind them applauding as they spent more on investments than they earned in income. Likewise, some companies today are losing money but have extremely attractive economics, and others are losing money the old-fashioned way—with bad business models.
四、我听到许多成功的投资者说,指数基金的兴起让主动型基金经理变得更容易了。我所深深敬佩的鲍波斯特集团(Baupost Group)创始人兼首席执行官塞思·卡拉曼也附和了这种说法,他曾说过:“[指数化]应该会给长期价值投资者带来明显的优势。有效市场理论内在的讽刺在于,相信它的人越多,相应地避开主动管理的人越多,市场就越可能变得无效。”22
IV. I hear a lot of successful investors say that the rise of indexing has made it easier to be an active manager. Seth Klarman, the founder and CEO of the Baupost Group whom I admire deeply, echoed this refrain when he said, “[Indexing] should give long-term value investors a distinct advantage. The inherent irony of the efficient market theory is that the more people believe in it and correspondingly shun active management, the more inefficient the market is likely to become.”22
表面上看,这个说法似乎有理:竞争的人少了,流入市场的信息也少了,因此更容易通过发现错误定价的资产来施展你的技能。但我认为事实可能恰恰相反,原因如下。
On the surface, this sounds like a plausible case: fewer people are competing and less information is finding its way into markets, hence it’s easier to express your skill by finding mispriced assets. But I think the opposite may be true, and here’s why.
一个很好的起点是诺贝尔奖得主、金融学教授比尔·夏普(Bill Sharpe)的《主动管理的算术》。其理念很简单:在扣除成本之前,主动管理下每 1 美元的平均回报率,与被动管理下每 1 美元的平均回报率相等。而在扣除成本之后,主动管理下每 1 美元的平均回报率,将低于被动管理下每 1 美元的平均回报率。
A good starting point is “The Arithmetic of Active Management” by professor of finance and Nobel-Prize winner, Bill Sharpe.23 The idea is simple: Before costs, the return on the average actively managed dollar will equal the return on the average passively managed dollar. And after costs, the return on the average actively-managed dollar will be less than the return on the average passively-managed dollar.
这本身对主动型基金经理来说并非什么新发现。按定义,扣除费用前的阿尔法值就是零。重要的是,你要想获得正的阿尔法,你交易对手方就必须有人获得负的阿尔法。
Now this isn’t by itself any revelation for active managers. Alpha before fees is zero by definition. What is important is that for you to earn positive alpha, someone on the other side of your trades has to earn negative alpha.
为了说得更生动一点,不妨想象一下:我邀请你周五晚上来我家打扑克,而且假设你想赢点钱。收到邀请后,你第一个问题应该是:“还有谁去?”
To make this more vivid, imagine that I invite you to my house Friday night to play poker, and let’s assume that you want to make some money. Upon receiving the invitation, your first question should be, “Who else will be there?”
如果我跟你说,会有一些比你差得多的富人玩家,你会立刻打算加入我。你并不保证能赢,但随着时间的推移,你的技巧会让你从那些冤大头手里赚到钱。
If I tell you there will be some rich people who are much worse players than you are, you’ll immediately make plans to join me. There’s no guarantee you’ll win, but over time your skill will allow you to take money from those patsies.
另一方面,如果我告诉你,来的选手个个都比你强,那你就该另做安排了。这种情况下,明摆着你就是那个冤大头——如果你还想保住自己的钱,这可不是什么好事。24
On the other hand, if I tell you that the players who are coming over are all better players than you are, you should arrange some alternative plans. In this case, it should be clear that you are the patsy—which is not good if you like to keep your money.24
我认为这个扑克故事同样适用于投资管理行业。我的猜想是,那些转向指数化投资的投资者,平均而言都是水平较弱的玩家。
I think the poker story carries over well to the investment management industry. My conjecture is that the investors who have turned to indexing are on average the weaker players.
把这个类比延伸一下:那些弱小的玩家正坐在你的赌桌旁喝着你的啤酒,但并没有参与游戏——所以他们既不会赢也不会输。我之所以提到他们在喝你的啤酒,是因为他们确实如此。
To stretch this analogy, the weak players are sitting at your poker table drinking your beer but are not playing— so they can’t win or lose. And the reason I mention that they are drinking your beer is because they really are
搭便车:指数基金依赖主动管理来进行价格发现和流动性提供。因此,主动管理费实际上补贴了整个指数管理行业。
free riding: indexers rely on active management for price discovery and liquidity. So active management fees subsidize the index management industry.
那么,如果我的论点大体正确,结果就是你在和更强的玩家对弈,要产生风险调整后的超额收益(即阿尔法)变得更难,而非更容易。虽然几乎可以肯定指数化投资已经在并将继续在市场中制造扭曲,但仍有大量主动型管理人随时准备从这些机会中套利。
So if my argument is reasonably accurate, you are left playing the stronger players, making it harder, not easier, to generate risk-adjusted excess returns, or alpha. And while there’s little doubt that indexing has and will create distortions in markets, there remain a substantial number of active managers at the ready to arbitrage those opportunities.
总结而言,我鼓励大家在思考那些权威人士的说法或论断时,永远回到第一性原理来审视。英国皇家学会的格言“Nullius in verba”是一个很管用的思考方式,它意在表达“不轻信任何人的话”。投资行业向来充斥着神话与妄想,这一点从过去到现在从未改变。
In summary, I want to encourage you to always go back to first principles when considering what the pundits say or assert. The motto of the Royal Society, “Nullius in verba,” is a useful way to think. It is meant to mean “take nobody’s word for it.” The investment industry is, and has always been, replete with myths and delusions.
我们的工作是,只要时机合适,就去破掉这些神像。
Our job is to bust them whenever appropriate.
