亚洲投资者 - 迈克尔·莫布森专访

Asian Investor - Michael Mauboussin Interview

莫布森认为存在大量“预期差”

Mauboussin sees abundant 'expectation gaps'

亚洲投资者(AsianInvestor):逆向投资的目的一直是追求阿尔法收益吗,还是说有时候取得贝塔收益也能让您满意?

AsianInvestor: With contrarian investing, is the aim always to achieve alpha, or are you happy with beta some of the time?

迈克尔·莫布森:在合适的情况下,我们更愿意称自己为价值投资者,而非逆向投资者。其次,投资的目标是通过比较资产基本面与价格预期,持续寻找价值显著高于价格的资产。以赛马为例,马匹的赔率代表价格预期,而马的状态、驯马师、历史战绩、赛道条件等则代表基本面。投注最热门的马赢不了最多的钱,关键是要找出预期与基本面之间的错误定价——即“预期差”。因此,您绝不应该满足于贝塔收益——那对您的客户毫无价值。阿尔法才是真正的目标。

Michael Mauboussin: We'd call ourselves value investors rather than contrarian where it makes sense. Second, the aim in investing is to constantly seek assets whose value is substantially higher than their price, by comparing asset fundamentals against price expectations. To take the example of horse racing, the horse's odds represent the price expectation, while the horse form, trainer, track record, track conditions and so on represent the fundamentals. You don't make the most money betting on the favourite, but by identifying the mispricing between expectations and the fundamentals -- the 'expectation gap'. Hence, you should never be happy with beta -- that's not getting you any value for your clients. Alpha what it's all about.

您的价值投资方法在某些市场比其他市场更有效吗?如果是,哪些市场更合适?

Does your approach to value investing work better in some markets than others? If so, which ones?

价值投资在趋势驱动型较强的市场中往往会遇到困难——在市场对价值不敏感时,比如近期的危机或 1990 年代末期,它通常受损最严重。不过,价值投资是一种久经考验的方法,长期来看应当能够成功。价值投资者将自己视为流动性的提供者。

Value investing tends to have a difficult time in markets that are very momentum-orientated -- it tends to suffer most when markets become value-insensitive, such as in the recent crisis or in the late 1990s. However, value investing is a tried-and-tested approach and should be successful over time. Value investors would see themselves as being providers of liquidity.

所以当市场下跌、投资者恐惧时,他们会买入;而当股价上涨、其他人热情高涨时,他们会寻找卖出机会。2009 年对价值投资者来说是一个好得多的环境——能够以相对便宜的价格买入股票,带来了不错的回报。

So when the market is down and investors are fearful, they will buy, while they will look to sell when stocks are up and everyone else is enthusiastic. In 2009, it's been a much better environment for value investors -- being able to buy relatively inexpensive stocks has led to good returns.

对于新兴市场或特定资产类别,您怎么看?

How about with regard to emerging markets or specific asset classes?

我对新兴市场的经验不多,但您可以扫描一下价值投资者的圈子,会发现有些人在这类市场上取得了成功——例如富兰克林坦伯顿的约翰·坦普尔顿。价值投资的思维方式适用于所有资产类别,只是程度不同。固定收益类资产通常更易于评估,因为它涉及公司固定的现金流;而股票则更难,因为你无法确定现金流何时来、来多少。至于大宗商品,它们传统上受供需影响,但在过去两年左右的时间里,投机者涌入,改变了这个市场的基调和风向。所以现在它更像一个趋势市场,而过去则主要由基本面驱动。

I don't have much experience of emerging markets, but you can scan the universe of value investors and see some that have been successful in such markets -- for example, John Templeton of Franklin Templeton. The value-investing mindset applies to all asset classes, but to different degrees. The fixed-income stream tends to be easier to assess, because it involves fixed cashflow streams from companies, while equities are more difficult because you're not sure when and how much cashflow will come. As for commodities, they are classically affected by supply and demand, but in the past couple of years or so speculators have come in and changed the tenor and tone of that market. So now it's more of a momentum market than in the past, when it was largely fundamentals-driven.

例如,2003 年末参与能源板块是一个好时机——那时大宗商品价格低廉,估值也不高。另一方面,对于大多数以基本面为导向的投资者来说,很难找到理由在油价每桶 80 美元(11 月中旬的水平)时投资石油。

For example, late 2003 would have been a good time to participate in energy -- when commodity prices were low and valuations were undemanding. On the other hand, most fundamentals-orientated investors would be hard pressed to find a case for investing in oil at $80 a barrel [its level around mid-November].

考虑到近期的危机中几乎所有的投资策略都遭受了损失,您的方法是哪些方面帮助了您,又在哪些方面拖了您的后腿?能给我具体例子吗?

Given that pretty much all investment strategies suffered during the recent crisis, how did your approach help you, and indeed where did it hinder you? Can you give me specific examples?

我有几点想法。回顾 2008 年,作为一个机构,我们可能错误地定性了这场危机,从而低估了它。我们觉得这是一场流动性危机,因此宽松的货币政策会带来强劲反弹。但实际上,这更像是一场抵押品危机。当市场上最大资产——房地产——的价格崩溃时,引发了追加保证金通知、更多资产抛售、又一轮追加保证金通知,如此循环。

I have a couple of thoughts on this. Reflecting on 2008, as an organisation we've probably mis-characterised the crisis and underestimated it as a result. We felt it was a liquidity crisis and that liberal monetary policy would therefore lead to a solid rebound. But it was actually more of a collateral crisis. When the price of the largest assets in the market -- real estate -- collapsed, that led to margin calls, more asset sales, more margin calls and so on.

另一个让我们措手不及的事情是,政府想要接管(美国住房抵押贷款融资机构)房利美和房地美,拯救(美国投行)贝尔斯登和(美国保险公司)AIG——然后却让雷曼兄弟倒闭。不是我们完全没有考虑过这些场景,只是我们低估了它们发生的概率。

Another thing that caught us flat-footed was the government's desire to take over [US mortgage financing agencies] Fannie Mae and Freddie Mac, and save [US investment bank] Bear Stearns and [US insurer] AIG -- and then to let Lehman Brothers fail. It's not that we didn't consider such scenarios at all, we just underestimated their probability.

关键在于,你是通过考察未来可能出现的结果来寻找“预期差”的——

The point is that you find 'expectation gaps' by looking coming potential outcomes -- and

而在这次危机中,我们可能没有充分考察或者正确加权潜在的不利结果。

during this crisis, we may not have looked at enough, or properly weighted, potentially adverse outcomes.

至于我们现在看到的形势走向,如果你想要估算 GDP 增长的幅度,有一些研究显示,经济下行的幅度与(随后)GDP 复苏的力度之间存在很好的相关性。这种方法预测美国 2010 年 GDP 增长率为 8% 到 9%,这相当惊人。而市场对明年 GDP 增长的一致预期实际上只有 2.5%——所以存在巨大的差距。我们并非主张 8% 那样强劲的增长,但我们倾向于认为增长会比人们想象的要好。

As for where we see things going now, if you want to figure out the magnitude of GDP growth, there's research that shows the magnitude of decline and does a good job of explaining the magnitude of [the subsequent] GDP recovery. This approach predicts US GDP growth for 2010 of 8-9%, which is remarkable. The consensus on GDP growth for next year is actually 2.5% -- so there's a yawning gap. We're not advocating growth as robust as 8%, but we would lean towards the notion that it will be better than people think.

不少经济学家都分享过这类分析——我尤其关注(美国公司)ISI Research 的埃德·海曼。他对历史有很好的把握,视角也很独到。

A number of economists have shared this type of analysis -- the one I follow particularly is Ed Hyman of [US firm] ISI Research. He has a good sense of history and good perspective.

在过去两年中,您在哪些方面和哪些地方最成功地利用了“预期差”?

How and where did you most succeed in exploiting the 'expectation gaps' in the past couple of years?

我们通过提升投资标的质量找到了机会。也就是说,投资那些历来质量较高的公司,比如科技和金融服务板块。你能够以较低的估值买入优质公司。而这些预期差在那些板块中仍然存在。

We found opportunities in the ability to move up the quality spectrum. That is, by investing in companies that have historically been higher-quality, such as in the technology and financial services sectors. You've been able to get good-quality companies at low valuations. And some of those expectation gaps are persisting in those sectors.

但您不担心金融板块潜在的重大问题吗,比如道德风险增加、监管可能收紧等等?

But aren't you worried about potentially major issues in the financial sector, such as increased moral hazard, likely tightening of regulations and so on?

现在的情况让我想起安然丑闻之后的市场——那件事让很多人警醒并更加关注。因此,人们对以恰当方式开展业务重要性的认识有所提高,这在住房活动高涨期间可能不那么明显。

The situation now reminds me of the markets after the Enron scandal -- that got a lot of people to sit up and take more notice. So there is a heightened awareness about the importance of conducting business properly, which may have been less evident during the swell in housing activity.

我们将拭目以待监管会如何变化以及采取何种形式。存在许多挑战。首先,我们不应该打昨天的仗。我不想过于悲观,但我不确定人们学到了多少。正如肯·罗格夫和卡门·莱因哈特在他们的著作《这次不一样》中所展示的,自从我们有市场以来,这类危机一直是市场的一部分。如果我们不再发生另一场危机,我会感到惊讶;这是市场体系的代价之一。

We'll see what happen with the regulations and what form they take. There are a number of challenges. Firstly, we shouldn't fight yesterday's battles. I don't want to be too pessimistic, but I'm not sure how much people have learnt. As Ken Rogoff and Carmen Reinhart show in their book This Time It's Different, such crises have been part of the markets as long as we've had markets. I would be surprised if we don't have another crisis; that's one of the costs of a market system.

至于监管,这次创新走在了基础设施的前面。例如,信用违约互换是有用的,不应该被完全取消,但通过让它们在交易所交易和清算,增加其透明度是明智的。这将为支撑更复杂金融交易的这些工具提供更多的透明度和稳定性。

With regard to regulation, the innovation got ahead of the plumbing this time. For example, credit-default swaps are useful and shouldn't be removed altogether, but it would be sensible to have greater transparency around them by having them traded on exchanges and cleared. This would provide more transparency and stability to the instruments underlying more complex financial transactions.

但存在对一些问题进行微观管理的风险,我认为美国政府对此有所警觉。同样重要的是要记住,金融服务业现在是一个全球性行业——因此各国之间需要制定相似的法规,否则金融机构会流向规则更有利的地方。

But there is a risk of micro-managing some issues, and I think the US administration is mindful of that. It's also important to bear in mind that financial services is now a global industry -- so you need to have similar regulations from country to country, as otherwise financial institutions will go to where the rules are more favourable.

您认为投资者总体上从危机中学到了什么吗——人们是否真正改变了他们对如何以及在哪里投资的观点?现在刺猬型投资者多还是狐狸型投资者多?

Do you think investors in general have learned from the crisis -- have people truly changed their views on how and where to place their money? Are there more foxes out there now than hedgehogs?

没有。所有这些危机的一个共同特点是人性——很难改变它。所以我怀疑我们会看到贪婪和恐惧的模式周期性地抬头;在不同的市场、不同的地方、不同的参与者,但却是同样的故事。

No. The consistent feature about all these crises is human nature -- it's very difficult to change it at all. So I suspect we'll see the same patterns of greed and fear periodically raising their heads; in a different market, a different place with different actors, but with the same story.

加州大学伯克利分校的心理学家菲利普·泰特洛克在 2006 年出版了一本书,指出狐狸——那些对很多事情都略知一二的人——比刺猬——只对一件事了解很多的人——做出的预测更准确。刺猬会有自己的高光时刻——例如,如果你在危机初期非常看空,你会名声大噪。同样,如果你在 2009 年看多,也会如此。你可能正确一次,但问题在于你是否能连续做出几个正确的预测。

Phil Tetlock, a psychologist at University of California at Berkeley, published a book in 2006 suggesting that foxes -- those that know a little about a lot of things -- make better predictions than hedgehogs, who know a lot about just one thing. Hedgehogs will get their moments of fame -- for example, if you were very bearish in the early phases of the crisis, you'll have made a name for yourself. And the same goes if you were bullish in 2009. You may get it right once, but the question is whether you can string together several correct predictions.
