更少的输家,还是更多的赢家?

Fewer Losers, or More Winners?

我的备忘录始于 1990 年 10 月,灵感来自两件事之间一个有趣的对照。一件是在明尼阿波利斯与戴维·范本肖滕的晚餐,他是通用磨坊养老基金的负责人。戴夫告诉我,在他任职 14 年间,该基金的股票回报率从未超过养老基金群体的第 27 百分位,也从未低于第 47 百分位。那么,这些稳稳落在第二四分位的年度回报,在 14 年里整体表现如何?排在第 4 百分位!我大为惊叹。事实证明,大多数瞄准前十分位业绩的投资者最终都会搬起石头砸自己的脚,但戴夫从不会。大约同一时间,一家著名的价值投资公司业绩惨淡,其总裁给出了一个轻松的自辩:“如果你想跻身资金管理人的前 5%,你也必须愿意接受落入后 5%。”我当即反应:“我的客户不关心我某一年是否排进前 5%,他们(和我)绝对没兴趣看到我跌进后 5%。”这两件事对我影响深远,帮助定义了我的——以及五年后成为橡树资本的——投资理念,其核心就是风险控制和一致性至上。这是 33 年前我在那第一份题为《通往业绩之路》的备忘录里写下的:我坚信,试图通过一连串前十分位的年份来打造卓越的长期记录,不太可能成功。相反,每年努力比平均水平好一点点——并通过纪律在糟糕时期取得远优于同行的相对业绩——才是:·

My memos got their start in October 1990, inspired by an interesting juxtaposition between two events. One was a dinner in Minneapolis with David VanBenschoten, who was the head of the General Mills pension fund. Dave told me that, in his 14 years in the job, the fund’s equity return had never ranked above the 27th percentile of the pension fund universe or below the 47th percentile. And where did those solidly second-quartile annual returns place the fund for the 14 years overall? Fourth percentile! I was wowed. It turns out that most investors aiming for top-decile performance eventually shoot themselves in the foot, but Dave never did. Around the same time, a prominent value investing firm reported terrible results, causing its president to issue an easy rationalization: “If you want to be in the top 5% of money managers, you have to be willing to be in the bottom 5%, too.” My reaction was immediate: “My clients don’t care whether I’m in the top 5% in any single year, and they (and I) have absolutely no interest in me ever being in the bottom 5%.” These two events had a strong influence on me and helped define my – and what five years later became Oaktree’s – investment philosophy, which emphasizes risk control and consistency above all. Here’s how I put it 33 years ago in that first memo, titled The Route to Performance: I feel strongly that attempting to achieve a superior long-term record by stringing together a run of top-decile years is unlikely to succeed. Rather, striving to do a little better than average every year – and through discipline to have highly superior relative results in bad times – is: • • •

更不容易产生剧烈波动,

更不容易造成无法挽回的巨大损失,而且,最关键的是,

更有可能奏效(毕竟我们大家都是凡人)。

less likely to produce extreme volatility, less likely to produce huge losses which can’t be recouped and, most importantly, more likely to work (given the fact that all of us are only human).

简单来说,通用磨坊的业绩记录告诉我:在股票投资中,如果你能避开输家(和亏损的年份),赢家自然会照顾自己。我坚信这一点同样适用于我们团队的机遇性细分领域——实现优于长期平均水平的表现,最好的基础就是不发生灾难。正如你所见,我与戴夫的那顿晚餐是一个转折性事件;他的方法显然正是适合我的那一种。(顺便说一句,我想分享的是,在与戴夫失联数十年后,他是最近几个月里众多写信鼓励我应对健康问题的好心人之一。这是我职业生涯所收获的众多个人红利中的一个绝佳例子。)

简要总结

那份最初的备忘录,以及上面引用的部分,包含了一句你可能听橡树资本说过的短语:如果我们避开输家,赢家自然会照顾自己。我和我的合伙人认为这句话极为贴切。

Simply put, what [General Mills’s] record tells me is that, in equities, if you can avoid losers (and losing years), the winners will take care of themselves. I believe most strongly that this holds true in my group’s opportunistic niches as well – that the best foundation for above-average long-term performance is an absence of disasters. As you can see, my dinner with Dave was a seminal event; his approach was clearly the one for me. (Incidentally, I want to share that after decades of not having been in touch, Dave was among the many kind people who wrote in recent months to encourage me vis-à-vis my health issue. This is a great example of the many personal dividends my career has paid.) Putting It in Brief That first memo, and the bit cited above, include a phrase you’ve likely heard from Oaktree: If we avoid the losers, the winners will take care of themselves. My partners and I considered this phrase so fitting

我们在 1995 年创立橡树资本时,把它定为我们公司的座右铭。理由很简单:如果我们投资于多元化的债券组合,并能避开那些违约的债券,那么所购非违约债券中的一部分,会因升级、收购等利好事件而受益。也就是说,赢家会自动浮现,无需我们刻意去寻找。

我们曾以为这句话颇有新意。但在 2005 年,我与塞思·卡拉曼合作修订本杰明·格雷厄姆和戴维·多德合著的 1940 年版《证券分析》(被誉为“价值投资圣经”)时,读到一些内容,才发现我们落后了大约 50 年。在塞思请我编辑的那部分里,我看到了格雷厄姆和多德对“固定价值”(即固定收益)投资的描述,称之为“一门消极的艺术”。他们是什么意思?

起初,我觉得他们的说法有些玩世不恭,但随后我明白了他们的深意。假设市场上有 100 只票面利率 8% 的债券。再假设其中 90 只会按期还本付息,10 只会违约。因为它们都是 8% 的债券,所以所有不违约的债券都会带来同样的 8% 回报——你买哪些并不重要。唯一重要的是,你是否买到了那 10 只违约债券中的任何一只。换句话说,债券投资者的业绩提升,靠的不是买什么,而是不买什么——不是找到赢家,而是避开输家。这就是“一门消极的艺术”。

关于这句话的由来,还有一则轶事:我一向对旧书情有独钟。几年前,我穿过拉斯维加斯一个会展中心去会见客户时,偶然遇到一场珍稀书展。我在一位相熟的书商摊位前停下脚步,目光立刻落在他出售的一本书上:杰西·利弗莫尔的《股票大作手操盘术》。书商标出了这样一句引文:“赢家自己会照顾好自己;输家永远做不到。”你或许会以为利弗莫尔借用了我的想法……直到你意识到,他和格雷厄姆、多德一样,是在 1940 年出版这些文字的。我的所谓创新,也就到此为止了。

在我采用这句格言时,我和合伙人主要投资于高收益债券。由于不可转换债券除了承诺的到期收益率之外,几乎没有上行空间,我们的主要任务确实就是避开那些不付款的发行人,同时假设付款者中的一部分,可能会让我们接触到一些积极进展。这是我们作为债券投资者,总结自身方法的一种恰当方式。

但幸运的是,我于 1987 年与布鲁斯·卡什合作,1988 年我们成立了第一只不良债务基金。那时我们开始投资于已经违约或看似即将违约的债券。我们认为,由于这些债券笼罩在负面阴影下,或许能以折扣价买入,从而带来资本增值的可能。布鲁斯此后以投资才能闻名,而他自 1988 年以来的回报,当然不能仅仅归功于避开损失。当你的目标回报远高于债券所能提供的水平时,光避开输家是不够的;你还得不时找到(或创造)赢家。布鲁斯及其团队所取得的回报证明了他们做到了这一点。

橡树资本现在拥有多种我称之为“进取型策略”的业务,意味着它们需要赢家。那么,为什么我们仍将上述格言作为座右铭,为什么“风险控制优先”仍是我们的投资理念第一条原则?答案是,我们希望风险控制的概念,始终是投资专业人员头脑中的首要考量。当他们审视一只证券时,我们希望他们不仅问“如果一切顺利,我能赚多少钱?”,还要问“如果事态不如预期,会发生什么?如果情况恶化,我可能损失多少?情况要糟到什么程度才行?”

在橡树资本,风险控制仍是第一位的。七十多年前,加州大学洛杉矶分校橄榄球教练亨利·拉塞尔“红”·桑德斯说过:“胜利不是一切,而是唯一。”(这句话也归功于绿湾包装工队的传奇教练文斯·隆巴迪。)虽然我还没完全搞清楚

that we adopted it as our motto when Oaktree was formed in 1995. Our reasoning was simple: If we invest in a diversified portfolio of bonds and are able to avoid the ones that default, some of the nondefaulters we buy will benefit from positive events, such as upgrades and takeovers. That is, the winners will materialize without our having explicitly sought them out. We thought that phrase was innovative. But in 2005, while working with Seth Klarman to update the 1940 edition of Benjamin Graham and David Dodd’s Security Analysis – the “bible of value investing” – I read something that indicated we were late by about 50 years. In the section Seth asked me to edit, I came across Graham and Dodd’s description of “fixed-value” (or fixed-income) investing as “a negative art.” What did they mean? At first, I found their observation cynical, but then I realized what they were saying. Let’s assume there are one hundred 8% bonds outstanding. Let’s further assume that ninety will pay interest and principal as promised and ten will default. Since they’re all 8% bonds, all the ones that pay will deliver the same 8% return – it doesn’t matter which ones you bought. The only thing that matters is whether you bought any of the ten that defaulted. In other words, bond investors improve their performance not through what they buy, but through what they exclude – not by finding winners, but by avoiding losers. There it is: a negative art. One more anecdote concerning the origin of the phrase: I’ve always been interested in old books. A few years ago, while walking through a Las Vegas convention center on the way to meet with a client, I came upon a rare book fair. I stopped at the booth of a book dealer I know, and my eye immediately fell on a book he had for sale: How to Trade in Stocks, by Jesse Livermore. Here’s the quote the dealer had highlighted: “Winners take care of themselves; losers never do.” You may be tempted to believe Livermore borrowed my idea . . . until you realize that, like Graham and Dodd, he published these lines in 1940. So much for my innovation. At the time I adopted that saying, my partners and I were primarily high yield bond investors. And since non-convertible bonds have little upside potential beyond their promised yield to maturity, it truly was the case that our main job was to avoid the non-payers, with the assumption that some subset of the payers would likely give us exposure to positive developments that occurred. It was an appropriate way to sum up our approach as bond investors. But fortunately, I joined up with Bruce Karsh in 1987, and in 1988 we organized our first distressed debt fund. Now we were investing in bonds that had defaulted or seemed likely to do so. We thought we might be able to buy them at bargain prices because of the cloud they were under, giving us the possibility of capital appreciation. Bruce has since become well known for his investing acumen, and, certainly, his returns since 1988 can’t be attributed to the mere avoidance of losses. When you aspire to returns well above those available on bonds, it’s not enough to avoid losers; you actually have to find (or create) winners from time to time. The returns generated by Bruce and his group show that they’ve done so. Oaktree now has a number of what I call “aspirational strategies,” meaning they need winners. So why do we still use the above phrase as our motto, and why is “the primacy of risk control” still the first tenet of our investment philosophy? The answer is we want the concept of risk control to always be top of mind for our investment professionals. When they review a security, we want them to ask not only “How much money can I make if things go well?” but also “What will happen if events don’t go as planned? How much could I lose if things get bad? And how bad would things have to get?” Risk control is still number one at Oaktree. Seventy-plus years ago, UCLA football coach Henry Russell “Red” Sanders said, “Winning isn’t everything, it’s the only thing.” (The saying is also attributed to Vince Lombardi, legendary football coach of the Green Bay Packers.) While I haven’t figured out

这段短语的确切含义是什么,我坚信对橡树资本而言,风险控制并非一切;它是唯一。

不是回避风险

理解风险控制与风险回避之间的区别,对投资者来说确实至关重要。风险回避基本上就是不做任何结果不确定且可能为负的事情。然而,投资的核心恰恰在于为追求诱人回报而承受不确定性。正因如此,风险回避通常等同于回报回避。你可以通过购买国库券或将钱存入政府保险的存款来规避风险,但这类投资的回报往往是投资界最低的,这并非没有道理。如果你确定能把钱拿回来,凭什么要为暂时让渡资金而获得丰厚报酬?

另一方面,风险控制则是指拒绝承担那些(a)超出你愿意承受的风险量级,和/或(b)不会因承担而获得充分回报的风险。过去我曾写过所谓“为获利而明智地承担风险”。以下是背后的故事:

我于 1978 年开始管理资金,当时花旗银行让我管理可转换债券和高收益债券的投资组合。前者大多是非投资级证券,由那些在寻求融资时别无选择的公司发行;后者按照当时的术语,是低评级的“垃圾债券”。显然,两者都涉及重大信用风险。大约在 1980 年,一家最早成立的金融新闻网络的记者问了我一个挑衅性的问题:“既然你知道有些发行人会违约,你怎么还能买高收益债券?”我的回答抓住了明智承担风险的精髓:“既然人寿保险公司知道所有人都会死,它们怎么还能为人们提供寿险?”

要点很简单:这些功能都可以以明智、可控风险的方式执行。要做到这一点,风险必须:

exactly what that phrase means, I’m firmly convinced that for Oaktree, risk control isn’t everything; it is the only thing. Not Risk Avoidance Understanding the distinction between risk control and risk avoidance is truly essential for investors. Risk avoidance basically consists of not doing anything where the outcome is uncertain and could be negative. And yet, at its heart, investing consists of bearing uncertainty in the pursuit of attractive returns. For this reason, risk avoidance usually equates to return avoidance. You can avoid risk by buying Treasury bills or putting your money into government-insured deposits, but there’s a reason why the returns on these are generally the lowest available in the investment world. Why should you be well paid for parting with your money for a while if you’re sure to get it back? Risk control, on the other hand, consists of declining to take risks that (a) exceed the quantum of risk you want to live with and/or (b) you wouldn’t be well rewarded for bearing. I’ve written in the past about what I call “the intelligent bearing of risk for profit.” Here’s the backstory: I got my start managing money in 1978, when Citi asked me to run portfolios of convertibles and high yield bonds. The former were mostly non-investment grade securities issued by companies that had no alternative when seeking to raise capital, and the latter were, according to the terminology of the day, low-rated “junk bonds.” Clearly, they both entailed significant credit risk. Around 1980, a reporter from one of the first financial news networks asked me a provocative question: “How can you buy high yield bonds when you know some of the issuers are going to default?” My response captured the essence of intelligent risk bearing: “How can life insurance companies insure people’s lives when they know they’re all going to die?” The point is simple: These functions can both be performed in an intelligent, risk-controlled way. For that to be the case, the risk has to be: • • • •

你意识到的风险,

你能分析的风险,

你能分散的风险,以及

你得到丰厚报酬去承担的风险。

risk you’re aware of, risk you can analyze, risk you can diversify, and risk you’re well paid to assume.

这类风险不必回避。如果你确有真知灼见,此类风险可以审慎地承担,并从中获利。

我认识几位投资者,他们承担的风险远高于橡树资本,其亏损年份也远比我们的更糟。但其中少数确有真才实学的人——我称之为“阿尔法”(稍后详述)——在顺境年份却能斩获巨额回报,以至于长期收益率出类拔萃。他们的客户回报丰厚……前提是他们有足够的胆识熬过那些艰难年份。因此,冒险本身并不算不明智,而回避风险只适合那些自认扛不住困境的投资者。

建立良好业绩记录

既然(a)除最谨慎的投资外,所有投资都伴随风险,且(b)风险的存在意味着结果不可预测、起伏不定,那么几乎没有什么投资者能只经历好年份,或能拼凑出

Risks like this needn’t be avoided. If you have real insight, such risks can be borne prudently and profitably. I know several investors who take much more risk than Oaktree does and whose bad years are much worse than ours. But the few who possess genuine skill – what I call “alpha” (more on that later) – produce jumbo returns in their good years, such that their long-term returns are exceptional. Their clients are well rewarded . . . assuming they have enough intestinal fortitude to hang in through the bad years. Thus, risk-taking isn’t unwise per se, and risk avoidance is appropriate only for investors who feel they can’t survive tough times. Building a Good Record Since (a) all but the most cautious investing entails risk and (b) the presence of risk means results will be unpredictable and inconsistent, very few (if any) investors are able to have only good years or to assemble

只包含赢家的组合。问题不在于你是否会遭遇失败,而在于失败有多少、有多惨,相对于你的赢家而言。

沃伦·巴菲特——可以说是长期业绩最好的投资者(当然也是长期业绩跨度最长的投资者)——被广泛描述为职业生涯中只有十二个重大的赢家。他的合伙人查理·芒格告诉我,他自己财富的绝大部分并非来自十二个赢家,而是只有四个。我相信沃伦和查理出色业绩的要素很简单:(a)大量投资做得还不错,(b)相对少数几个大赢家,他们重仓并持有数十年,(c)相对较少的大输家。没有人应该指望自己——或指望自己的资金管理人——全是赢家、没有输家。

事实上,没有输家并不是一个有用的目标。唯一能确保做到这一点的方法就是不承担任何风险。但正如我之前所说,回避风险很可能导致回避回报。有一种风险叫做承担太少风险的风险。大多数人在理智上明白这一点,但人性使许多人难以接受这样的观念:愿意承受一些损失是投资成功的基本要素。

今年夏天观看了几场精彩的网球比赛——一直到上周末的美国公开赛——我要重提一个我在备忘录《敢于大胆 II》(2014 年 4 月)中首次提出的网球类比。如果我去打网球,说:“今天,我不要发球失误。”我的发球必须如此软弱无力,以至于对手很可能直接把我打穿。网球选手要想成功,就必须承担一些风险(见下文)。如果你的发球没有一个落在发球区之外,那你发球可能太保守,赢不了。投资也是如此。正如我的长期搭档谢尔登·斯通所说:“如果你没有经历过任何违约,那你可能承担的信货风险不够。”

赢家的数据

回头看,我发现在 20 世纪 90 年代、21 世纪头十年和 2010 年代,每十年我都写了一整篇备忘录来类比投资与体育。这一次,在我写备忘录的第四个十年里,我要再花几段谈谈网球。

如上所述,网球与投资可以非常恰当地类比。安全击球然后被打爆?还是尝试自己无法稳定打出的球然后自毁?查尔斯·D·埃利斯的文章《输家的游戏》(《金融分析师杂志》,1975 年 7/8 月)在我成长为投资者的过程中堪称奠基之作。他指出有两种网球选手……实际上,是两种不同类型的网球比赛。职业选手打的是赢家的游戏:他们靠打出制胜分来赢球(在网球中,这意味着对手无法回击的击球)。由于他们的比赛很大程度上在自己掌控之中,他们通常能打出想要的球,其中最出色的就能得分。但业余网球是输家的游戏:赢家通常是打出最少失误的那个人。如果你能把球保持在界内足够久,最终对手会把球打出界或打下网。业余选手不需要打出制胜分就能赢,这其实是件好事,因为业余选手通常无法稳定地打出制胜分。

快速看一眼今年温布尔登的一些统计数据,提供了大量值得思考的内容。我先看男子四分之一决赛,对阵双方是赛会 3 号种子丹尼尔·梅德韦杰夫和非种子选手克里斯托弗·尤班克斯。尤班克斯身高 6 英尺 7 英寸,运动能力极强,他以一路杀入四分之一决赛震惊了所有人。但他面对的是梅德韦杰夫,一个多年来紧随男子网坛“三巨头”之后的人:诺瓦克·德约科维奇、拉斐尔·纳达尔和罗杰·费德勒。

作为明显的下风者,尤班克斯可能明白自己不太可能在耐力或稳定性上胜过梅德韦杰夫。因此,他必须去拼制胜分。如果这就是尤班克斯的计划,他执行得相当成功。

portfolios that contain only winners. The question isn’t whether you’re going to have losers, but rather how many and how bad relative to your winners. Warren Buffett – arguably the investor with the best long-term record (and certainly the longest long-term record) – is widely described as having had only twelve great winners in his career. His partner Charlie Munger told me the vast majority of his own wealth came not from twelve winners, but only four. I believe the ingredients of Warren’s and Charlie’s great performance are simple: (a) a lot of investments in which they did decently, (b) a relatively small number of big winners that they invested in heavily and held for decades, and (c) relatively few big losers. No one should expect to have – or expect their money managers to have – all big winners and no losers. In fact, not having any losers isn’t a useful goal. The only sure way to achieve that is by not taking any risk. But, as I said earlier, risk avoidance is likely to result in return avoidance. There’s such a thing as the risk of taking too little risk. Most people understand this intellectually, but human nature makes it hard for many to accept the idea that the willingness to live with some losses is an essential ingredient in investment success. Having watched some great tennis this summer – right through the U.S. Open this past weekend – I’ll recycle a tennis analogy I first suggested in my memo Dare to Be Great II (April 2014). What if I went out to play tennis and said, “Today, I’m not going to commit any service faults”? My serves would have to be so meek that my opponent would likely destroy them. Tennis players have to take some risk if they hope to succeed (see below). If none of your serves fall outside the service box, you’re probably serving too cautiously to win. The same is true of investing. As my long-time partner Sheldon Stone puts it, “If you don’t experience any defaults, you’re probably not taking enough credit risk.” Winners’ Stats Looking back, it turns out I devoted an entire memo to analogies between investing and sports once per decade in the 1990s, the 2000s, and the 2010s. This time, in my fourth decade of memo-writing, I’m going to devote a few more paragraphs to tennis. As mentioned above, tennis makes for very apt comparisons to investing. Hit safely and get blasted? Or try for shots you can’t make consistently and beat yourself? Charles D. Ellis’s article “The Loser’s Game” (The Financial Analysts Journal, July/August 1975) was truly seminal in my development as an investor. He pointed out that there are two kinds of tennis players . . . actually, two different types of tennis games. Professionals play a winner’s game: They win by hitting winners (in tennis, that means shots the opponent can’t return). Since their game is so much within their control, they can usually produce the shots they want, the best of which win points. But amateur tennis is a loser’s game: The winner is usually the person who hits the fewest losers. If you can just keep the ball in play long enough, eventually your opponent will hit it off the court or into the net. The amateur doesn’t have to hit winners to win, and that’s a good thing, because he or she generally is incapable of doing so dependably. A quick look at some statistics from this year’s Wimbledon provides a great deal of food for thought. I’ll look first at the men’s quarterfinal match between Daniil Medvedev, the #3 seed in the tournament, and unseeded Christopher Eubanks. Eubanks, 6’7” and highly athletic, surprised everyone with his rush to the quarterfinals. But, in Medvedev, he was playing someone who’s spent years trailing just behind the “big three” of men’s tennis: Novak Djokovic, Rafael Nadal, and Roger Federer. As a pronounced underdog, Eubanks probably recognized that he wasn’t likely to outlast or out-steady Medvedev. Thus, he had to go for winners. If that was Eubanks’s plan, he succeeded in executing it. He

他拿下 74 个制胜分,梅德韦杰夫只有 52 个,而且他激进地网前截击 67 次(收获 44 个制胜分),梅德韦杰夫只有 8 次(拿下 4 个制胜分)。这些进攻数据非常亮眼。

问题在于——我亲身经历过多次——如果你面对的是一个比你更强的对手,你不得不尝试那些并不完全在你能力范围内的击球,才有希望获胜。因此,除了那 74 个制胜分,尤班克斯还犯了 55 次非受迫性失误(非受迫性失误是指并非因对手高质量击球而被迫犯下的错误;最容易犯非受迫性失误的方式就是追求制胜分结果打丢)。相比之下,梅德韦杰夫只有 13 次非受迫性失误。

结论是:尤班克斯的制胜分远超梅德韦杰夫,但他每四个制胜分就有三个非受迫性失误,而梅德韦杰夫每四个制胜分只有一个。梅德韦杰夫赢下 53% 的得分,尤班克斯只有 47%,所以梅德韦杰夫赢了比赛。教训是,光有更多制胜分还不够。要赢球——无论是网球还是投资——你必须在制胜分和失误之间建立有利的关系。你可以靠少数制胜分但更少的失误取胜,也可以靠大量失误但更多的制胜分取胜。单纯追求最大化制胜分或最小化失误都不一定够,关键在于平衡。

这让我想到温网男单决赛。这场激动人心的对决,一边是历史大满贯冠军最多的德约科维奇(在温网、美网、法网和澳网共拿下 23 个冠军),另一边是崭露头角的 20 岁小将卡洛斯·阿尔卡拉斯,他总共只有一个大满贯。和尤班克斯一样,阿尔卡拉斯打法大开大合、运动能力出众,追求大量制胜分。从他的发球就能看出来:阿尔卡拉斯有 7 次双误,是德约科维奇 3 次的两倍多。但同样,单一数据说明不了太多,因为阿尔卡拉斯追求大力发球,换来了 9 个 ACE 球(对手连球拍都碰不到的发球),是德约科维奇 2 次的四倍多。这体现了两人的风格差异。最终,阿尔卡拉斯以 66 个制胜分赢下比赛,而德约科维奇只有 32 个。

所以,阿尔卡拉斯用更“凶猛”、高风险的打法击败了德约科维奇,而梅德韦杰夫用更稳健、风险控制的风格战胜了尤班克斯。两种风格本身并无高下之分,风格本身从来不决定结果;关键是风格加执行。我的网球老师霍尔迪·巴列斯特(Jordi Ballester)解释说:“阿尔卡拉斯打法更具侵略性。考虑到他的天赋水平,正如他在温网所展现的,如果他状态好,他能击败德约科维奇(或任何对手)。如果他状态不佳,他很可能输球。”

值得注意的是,网坛三巨头开创了一个不可思议的时代。在 2023 年温网之前的 19 年里,他们合共拿下了 75 个大满贯冠军中的 65 个,占比 87%。值得注意的是,他们中没有一个是阿尔卡拉斯那种“重炮手”。他们能在四五个小时里保持顶尖击球水平而不犯太多错误,这通常就够了。

对赢家股的需求

在我的职业生涯中,有好几次少数几只股票贡献了市场涨幅中不成比例的巨大份额。在这方面,关于所谓“七圣徒”已有很多文章:苹果、微软、Alphabet(谷歌母公司)、亚马逊、英伟达、特斯拉和 Meta(Facebook 母公司)。今年多个时间点,这七只股票占各种股票指数涨幅的大部分甚至全部。以下是《金融时报》6 月的报道:

最大的七个成分股……大幅上涨,今年涨幅在 40% 到 180% 之间。其余 493 家公司(在标普 500 指数中)整体持平。

achieved 74 winners to Medvedev’s 52, and he aggressively rushed the net 67 times (for 44 winners) compared to Medvedev’s 8 (for 4 winners). These are great offensive stats. The problem is that – as I’ve experienced firsthand many times – if you’re up against a player who’s better than you are, you have to attempt shots that aren’t firmly within your competence in order to have a hope of winning. Thus, along with his 74 winners, Eubanks was guilty of 55 unforced errors (mistakes that aren’t forced by good shots from one’s opponent; the easy way to make an unforced error is to go for a winner and miss). In comparison, Medvedev committed only 13 unforced errors. Bottom line: Eubanks had considerably more winners than Medvedev, but he had three unforced errors for every four winners, whereas Medvedev had only one per four. Medvedev won 53% of the points played versus Eubanks’s 47%, and thus he won the match. The lesson is that it’s not enough to have more winners. To win – in tennis as in investing – you have to have a favorable relationship between winners and losers. You can win by having a few winners but fewer losers or by having a lot of losers but more winners. Neither maximizing winners nor minimizing losers is necessarily enough. It’s all in the balance. And that leads me to the Wimbledon men’s final. This exciting match pitted Djokovic, who had won the most Grand Slam championships in history (23 combined at Wimbledon, the U.S. Open, the French Open, and the Australian Open), against up-and-coming 20-year-old Carlos Alcaraz, who had a grand total of one. Like Eubanks, Alcaraz plays a big, athletic game and goes for a lot of winners. You can see that in his serving: Alcaraz had seven double faults, more than twice Djokovic’s three. But, again, a single statistic tells us very little, since Alcaraz’s attempts at big serves gave him nine aces (serves his opponent couldn’t even get his racquet on), more than four times Djokovic’s two. This is an indication of the players’ respective styles. In the end, Alcaraz won the match with 66 winners, whereas Djokovic had only 32. So, Alcaraz beat Djokovic with a “bigger,” high-risk game, while Medvedev beat Eubanks with his steadier, risk-controlled style. Neither approach is better than the other per se. Style alone never determines outcome; it’s a matter of style plus execution. My tennis teacher, Jordi Ballester, explains: “Alcaraz plays a more aggressive game. Given his high level of talent, as he showed at Wimbledon, if he has a good day, he can beat Djokovic (or any other opponent). If he’s off, he may well lose.” It’s interesting to note that tennis’s big three presided over an incredible era. In the 19 years leading up to Wimbledon 2023, they won a combined 65 – or 87% – of the 75 Grand Slam championships. Notably, none of them was a “big hitter” in Alcaraz’s mold. Their ability to hit at a fabulous level for four or five hours without committing many errors was usually enough. The Need for Winning Stocks There have been several times over the course of my career when a small number of stocks have accounted for a disproportionately large share of the market’s gains. In this regard, a lot has been written about the so-called “magnificent seven”: Apple, Microsoft, Alphabet (owner of Google), Amazon, Nvidia, Tesla, and Meta (owner of Facebook). At various points in time this year, these seven stocks accounted for most or all of the gains of various equity indices. Here’s how the Financial Times put it in June: Seven of the biggest constituents . . . have ripped higher, gaining between 40 per cent and 180 per cent this year. The remaining 493 companies [in the Standard & Poor’s 500 stock index] are, in aggregate, flat.

大型科技公司对指数的支配程度前所未有。这七只股票中仅五只就占整个指数市值近四分之一。(《推动美国股市上涨的七家公司》,《金融时报》,2023 年 6 月 14 日。)这些股票今年大部分时间里的优异表现或许独一无二,但这种现象并不新鲜。2017 年也曾出现过少数几只股票大体扛起市场上涨的情形。当时是“FAANG”股:脸书、亚马逊、苹果、奈飞和谷歌/字母表公司。《金融时报》也挖出了这段历史:

市场头重脚轻,尤其是美国市场,并不新奇。“现在标普里的科技大股,和过去石油公司的处境、或 1960 年代的‘漂亮五十’如出一辙,”巴黎 Carmignac 资产管理公司跨资产团队主管弗雷德里克·勒鲁说——这番话指的是那股炒作少数几只高增长公司股票(如 IBM、柯达、施乐)的狂热,把它们推到高位后迎来重挫。“这是问题,但也是反复出现的问题。”(同前。)

就我们大多数人记事以来,主动型投资者一直难以追上股票指数。正因如此,近几十年来,被动投资在投入股市的资金中占了相当大份额。主动投资的落后,主要被归因于市场有效性、管理费和投资者失误这三者的叠加。我觉得还有另一个原因:主动型投资者需要赢家。

要是今年早些时候你没有持有那七圣徒呢?显然,你会远远落后于指数。要是你持有它们,但比例低于它们在指数中的权重呢?你仍会落后,但差距小一些。所以,按定义来说,跟上指数就需要对大涨赢家的敞口至少不低于它们在指数中的分量。这一点似乎清楚。再想想那个分量。假设你从 20 年前——2003 年夏天——起步,按指数配比买入苹果股票,经拆股调整后价格为 0.37 美元。关键问题很简单:股价上涨时,你拿得住吗?

正如我在备忘录《获利了结》(2022 年 1 月)里所描述的,多数投资者信奉“落袋为安”“见好就收”或“修剪果树”的传统智慧。毕竟,老话说得好,“获利了结永远不会让人破产。”投资者常常卖掉一部分赢家股,原因很简单:他们害怕看着自己的收益溜走,那会带来懊悔、客户指责,甚至客户流失。

多数人早在 2013 年夏天股价涨到 15 美元时,就会卖掉部分或全部苹果持仓。当 10 年后股价达到你原始成本的 40 倍时,你会怎么做?如今,又是一个 10 年过去,苹果股价在 180 美元左右——较 2013 年上涨 12 倍,较 2003 年上涨近 500 倍。关键在于,面对这些涨幅,很少有投资者还会全部持有当初买入的股份。但如果他们在指数构建者没有卖出苹果股票时卖掉了,那他们很可能就跟不上指数。这种情况可以这样概括:

Big tech companies dominate the index to an unprecedented degree. Just five of those seven stocks represent nearly a quarter of the market capitalisation of the entire index. (“The seven companies driving the US stock market rally,” Financial Times, June 14, 2023.) The extent of these stocks’ outperformance for much of this year may be unique, but the phenomenon is not. It was also the case in 2017 that a few stocks were largely responsible for carrying the market upward. Then it was the “FAANGs”: Facebook, Amazon, Apple, Netflix, and Google/Alphabet. The Financial Times highlighted this history as well: Top-heaviness, particularly in US markets, is not new. “The big tech stocks in the S&P now are the same situation as oil companies were in the past, or the Nifty 50 in the 1960s,” says Frédéric Leroux, head of the cross-asset team at Carmignac in Paris – a nod to the craze that swept shares in a small number of fast-growing companies such as IBM, Kodak and Xerox higher before a heavy decline set in. “It’s a problem, but it’s a recurring problem.” (Ibid.) For as long as most of us can remember, active investors have had a tough time keeping up with the equity indices. For this reason, in recent decades, passive investing has taken a substantial share of equity capital invested. Active investing’s shortfall has been attributed primarily to the combination of market efficiency, management fees, and investor error. I think there’s another reason: active investors’ need for winners. What if you didn’t own the magnificent seven earlier this year? Clearly, you’d be far behind the indices. What if you owned them, but in smaller proportions than their weightings in the indices? You’d still lag, but by a smaller amount. So, by definition, keeping up with the indices requires having exposure to the big winners that is at least equal to their representation in the indices. That much seems clear. Now, think about that representation. Let’s say you started off 20 years ago – in the summer of 2003 – with an index-sized helping of Apple at a split-adjusted price of $0.37. The key question is simple: Would you have held on as it rose? As I described in my memo Selling Out (January 2022), most investors subscribe to the conventional wisdom of “taking profits,” “taking some money off the table,” or “topping the trees.” After all, as the old saying goes, “No one ever went broke taking profits.” Investors often sell off some of their winners for the simple reason that they’re afraid to watch as they give up their gains, which can lead to regret, criticism from clients, and/or lost accounts. Most people would have sold part or all of their Apple holding by the time the price reached $15 in the summer of 2013. What would you have done when it hit 40 times your original cost after 10 years? Today, another 10 years later, Apple is around $180 1 – up 12x since 2013 and up by almost 500x since 2003. The point is, in the face of these gains, very few investors would still hold all they’d originally bought. But if they sold Apple stock when the constructors of the index didn’t, they’ve probably failed to keep up with the index. The situation can be summed up as follows:

股票指数的表现常常被少数几只股票或几组股票所主导。领涨股带来的收益可能让它们显得估值过高,从而让人倾向于获利了结。人性使然——尤其是避免后悔的愿望——进一步增强了卖出的动机。显然,如果你把赢家股的持仓比例降到其在指数中的权重之下,而这些赢家股又继续跑赢大盘,你就很难跟上指数的步伐。

The performance of the equity indices is often dominated by a few stocks or groups of stocks. The gains of the leaders can make them seem expensive, arguing for profit-taking. Human nature – especially the desire to avoid regret – adds to the motivation to sell. By definition, if you reduce your holdings of the winners relative to their representation in the indices and these winners continue to outperform, you’ll have a tough time keeping up.

在我 2015 年 3 月写的备忘录《流动性》里,我引用了儿子安德鲁的一个观点。大意是,他说,“如果你看到一只股票 25 年的走势图,心想,‘天哪,我当初要是持有这只股票就好了’,那就想想,在这 25 年里,你得有多少次说服自己别把它卖掉。”我怀疑没多少人能眼看着苹果从 0.37 美元涨到 180 美元而一股不卖。有多少主动型投资者能容忍苹果占自己投资组合近 8% 的比例——这正是它在标普 500 指数近期峰值时的权重?但——简单点说——如果他们卖掉苹果,就跑输了指数。

归根结底,赢家并非完全可有可无。如果你想至少跟上指数的步伐,你可能必须持有接近指数平均水平的仓位。(这并非完全不可避免。你也可以通过少持有一些输家来达到这个目标。)

风险承担的角色

In my memo Liquidity (March 2015), I included an insight from my son Andrew. To paraphrase, he said, “If you look at the chart of a stock that’s been up for 25 years and say, ‘Man, I wish I’d owned that stock,’ think about all the days you would have had to talk yourself out of selling.” I doubt many people watched Apple go from $0.37 to $180 without selling any. How many active investors would allow Apple shares to constitute nearly 8% of their portfolios, which was its weight in the S&P 500 at the recent peak? But – to oversimplify – if they sold Apple, they’ve lagged. The bottom line is that winners aren’t entirely dispensable. If you hope to at least keep up with the indices, you probably have to have an average representation in them. (This isn’t entirely inescapable. You might also achieve that goal by holding fewer of the losers.) The Role of Risk Bearing

Return

Return

我打算用我最喜欢的一张图表来结束这份备忘录。55(!)年前,我在芝加哥大学读研究生时,学到的是这样看待风险与回报之间的关系:

I’m going to conclude this memo using my favorite graph. When I attended graduate school at the University of Chicago 55 (!) years ago, I was taught to view the relationship between risk and return as follows:

Risk

Risk

但我越想越觉得,那种以线性方式呈现的风险与回报关系,仿佛在告诉投资者,承担更多风险就能指望获得更高回报,这让我愈发不满。毕竟,如果真是这样,高风险投资就不会显得更冒险了。于是,在我 2006 年 1 月写的那份备忘录《风险》里,我提出了另一种描述这一关系的方法,在直线上叠加一系列侧放的钟形概率分布图。

But the more I thought about it, the more unhappy I was with the way the linear presentation of the purported relationship tells investors that they can count on achieving higher returns as a result of taking more risk. After all, if that were really the case, risky investments wouldn’t be riskier. Thus, in my memo Risk (January 2006), I suggested a different way of depicting the relationship by superimposing on the line a series of bell-shaped probability distributions turned on their side:

这种新的审视方式并不表示承担更多风险(在图中从左向右移动)就必然带来更高回报,而是指出,随着风险增加,(a)预期回报随之上升,与原版描述一致;(b)可能结果的分布范围变得更广;(c)糟糕的情形会变得更糟。换句话说,风险更高的投资带来了更高回报的潜力,同时也引入了其他不太令人满意的副作用。这正是它们被称为风险更高的原因。自写下那份备忘录以来,我意识到这种思考方式有着广泛的适用场景。以下列举几例:

Rather than implying that taking more risk – moving from left to right in the graph – assures higher returns, this new way of looking at the relationship suggests that as you take more risk, (a) the expected return increases, as per the original version above; (b) the range of possible outcomes becomes wider; and (c) the bad possibilities become worse. In other words, riskier investments introduce the potential for higher returns, but also the possibility of other less-desirable side effects. That’s why they’re described as being riskier. Since writing that memo, I’ve concluded that this way of thinking about things has a great many applications. Here are a few:

如上图所示,高风险策略既可能带来丰厚回报,也可能造成损失。

那么,在这条光谱上,哪里才是合适的位置?哪里能找到最佳的风险/回报平衡点?简短的回答是,按照投资理论——尤其是有效市场假说——并不存在更优或更差的位置。有效市场假说认为,市场对证券的定价使得(a)价格等于其内在价值,(b)承担额外风险能得到公平回报。因此,廉价交易和过度定价都不可能存在。这就是为什么按照该理论,“你无法战胜市场”。

该理论还提出,如果市场处于“均衡”状态,预期回报的每次变化都与所承担风险的变化相称,以至于曲线上所有位置的吸引力都相同。向左移动,你规避了一些风险,但预期回报也下降;向右移动,预期回报增加,但风险也随之上升。光谱上没有任何位置优于其他位置。这就像抛硬币(有效市场假说认为主动投资就是这样):正面和反面都不是更聪明的选择。

As the above graphs indicate, a high-risk approach introduces the potential for huge returns . . . as well as the possibility of loss. So, where’s the right place to be on this spectrum? Where can one find the best risk/return bargains? The short answer is that, according to investment theory – particularly the Efficient Market Hypothesis – there are no better (or worse) places to be. The EMH says markets price securities such that (a) their price equals their intrinsic value and (b) bearing incremental risk is rewarded fairly. Thus, bargains and over-pricings can’t exist. This is why, according to the theory, “you can’t beat the market.” The theory also suggests that if a market is at “equilibrium,” each change in prospective return is fair relative to the change in risk borne, such that all positions on the curve are equivalent in attractiveness. Move to the left, and you avoid some risk, but your prospective return drops. Move to the right, and your prospective return increases, but so does your risk. No position on the spectrum is superior to any other. It’s like a coin toss (which the EMH suggests active investing is): Neither heads nor tails is the smarter call.

实践中有何不同?

我最喜欢的一句名言据称出自阿尔伯特·爱因斯坦和尤吉·贝拉等人之口:“理论上,理论与实践没有区别;实践上,确有区别。”如果市场有效,证券总是被正确定价,那么主动投资便毫无价值。事实是,许多主动型基金经理,尤其是在发达市场股票领域,未能展现出创造价值的能力,或未能创造足够价值以证明其管理费合理。这正是指数基金诞生的主要原因,也是近几十年来大量股票资本涌入指数与被动投资的原因所在。然而,我坚信市场有时会定价过高,有时又会定价过低。某些市场或板块相对于其他市场或板块,也有定价过高或过低的时候。在这种情况下,部分证券可能被定得过高或过低,因此风险曲线上的一些位置会比另一些位置提供更划算的买卖机会。

理论假设投资者理性而客观,但心理上的过度行为打破了这一假设。以全球金融危机期间的投资环境为例。正如我在 7 月备忘录《测温》中所描述的,2008 年底,投资者对金融业崩溃忧心忡忡,以至于在证券价格暴跌时恐慌性抛售。过度的风险厌恶导致风险/回报曲线变得更陡峭(每多承担一单位风险所获得的回报增加),甚至可能向上弯曲(使得在曲线高风险端进行投资所获的补偿变得不成比例地慷慨)。因此,在过度风险厌恶的时期,曲线更激进的一端可能是更明智的选择(而在风险承担被过度追捧的时期,更安全的一端则能提供更优的选项)。

What About in Practice? One of my favorite quotes is attributed to Albert Einstein and Yogi Berra, among others: “In theory, there is no difference between theory and practice. In practice, there is.” If markets are efficient and securities are always priced correctly, there can be no value in active investing. The truth is that many active managers, especially in developed market equities, have failed to demonstrate the ability to add value, or to add enough value to justify their management fees. This is largely why index funds were created and why a significant amount of equity capital has migrated to index and passive investing in recent decades. And yet, I firmly believe there are times when the markets are overpriced and times when they’re underpriced. There are also times when particular markets or sectors are overpriced or underpriced relative to others. In these instances, some securities can be priced too high or too low, and thus some positions on the risk curve can offer better bargains than others. The theory assumes investors are rational and objective, but psychological excesses violate that assumption. Take, for example, the investment environment during the Global Financial Crisis. As I described in my July memo Taking the Temperature, in late 2008, investors were so worried about a financial sector meltdown that they panicked and sold securities aggressively as their prices collapsed. Excessive risk aversion causes the risk/return line to steepen (increasing the return for each incremental unit of risk borne) and perhaps even to curve upward (rendering the compensation for making investments at the risky end of the spectrum disproportionately generous). Thus, in periods of excessive risk aversion, the riskier part of the curve can be the smarter place to be (and in periods when risk bearing is too eagerly embraced, the safer part can offer a superior proposition).

最后一点我想谈的是所谓的“阿尔法”,也就是个人投资技能。有效市场假说之所以不屑于战胜市场的努力,是因为它坚信证券价格始终定价正确,因此识别低价买入机会和高估规避风险的能力根本不存在。理论断言市场不存在精通一说,意味着没人具备构建跑赢大盘组合的技能。这就是为什么我在上面把钟形曲线画成对称的:在有效市场中,投资者只能接受市场给予的一切。

但我确信,在某些市场和某些人身上,通过技能提升回报的潜力确实存在。拥有阿尔法的投资者能够改变上述图形的分布形态,使其不再对称,即分布中代表较差结果的部分比代表较优结果的部分更小。事实上,这正是阿尔法的真正含义:拥有阿尔法的投资者能够进入某个市场,通过运用自身技能,在不必承担全部下行风险的情况下,获取该市场提供的上行潜力。在我 2022 年 11 月的备忘录《什么才真正重要?》中,我曾指出卓越投资的关键特征是不对称性——上行空间大于下行空间。阿尔法使杰出投资者能够调整概率分布,使其偏向积极方向,从而获得更优的风险调整后回报。

The last element I want to touch on is what I call “alpha,” or individual investing skill. The reason the EMH disdains efforts to beat the market is its conviction that since securities are always priced correctly, the ability to identify bargains to buy and over-pricings to avoid can’t exist. Theory’s assertion that there’s no such thing as mastery of markets implies that no one has the skill to assemble portfolios that outperform. This is why I depict the bell-shaped curves above as symmetrical: In an efficient market, investors can only take what the market gives them. But I’m convinced the potential to improve on that through skill does exist in some markets and some people. Investors who possess alpha have the ability to alter the shape of the distributions in the graphs above so that they’re not symmetrical, in that the portion of the distribution representing the less desirable outcomes is smaller than the portion representing the better ones. In fact, that’s what alpha really means: Investors with alpha can go into a market and, by applying their skill, access the upside potential offered in that market without taking on all the downside risk. In my memo What Really Matters? (November 2022), I said the key characteristic of superior investing is asymmetry – having more upside than downside. Alpha enables exceptional investors to modify the probability distributions such that they are biased toward the positive, resulting in superior risk-adjusted returns.

如果阿尔法(alpha)指在未承担完全相应风险的情况下获取收益的能力,那么拥有这种能力的投资者可以通过两种途径实现:要么在减少风险的同时尽量少牺牲收益,要么在增加潜在收益时让风险增幅不成比例地小于收益增幅。换句话说,技巧可以让某些投资者靠强调进攻性跑赢,也可以让另一些靠强调防守性胜出。在这两种策略之间做选择,取决于投资者拥有的是哪种阿尔法:是擅长创造惊人……

If alpha is the ability to earn return without taking fully commensurate risk, investors possessing it can do so by either reducing risk while giving up less return or by increasing potential return with a less-than-commensurate increase in risk. In other words, skill can enable some investors to outperform by emphasizing aggressiveness and some by emphasizing defensiveness. The choice between these approaches depends on the type of alpha an investor possesses: Is it the ability to produce stunning

在可接受的风险下获得良好回报,还是以极低风险创造可观回报?几乎找不出同时具备这两种阿尔法能力的投资者,而绝大多数人一种都不具备。缺乏阿尔法的投资者,不应指望自己能实现任何一种不对称性——也就是跑出更优风险调整后收益。可大多数人偏都觉得自己有这个本事。

两种策略——少踩雷还是多抓牛——如何取舍,取决于每位投资者的本事、收益预期和风险承受力。和我聊的许多话题一样,这里没有标准答案,只有选择。

returns with tolerable risk, or the ability to produce good returns with minimal risk? Almost no investors possess both forms of alpha, and most possess neither. Investors who lack alpha shouldn’t expect to be able to produce either version of asymmetry – that is, to be able to generate superior risk-adjusted returns. However, most believe they do have it. The proper choice between the two approaches – fewer losers or more winners – depends on each investor’s skill, return aspiration, and risk tolerance. As with many of the things I discuss, there’s no right answer here. Just a choice.
