价值投资依然有效的原因

-Security Analysis Six Edition: Page xxi-Page xxii

 

In the aggregate, the value-investing community is no longer the very small group of adherents that it was several decades ago. Competition can have a powerful corrective effect on market inefficiencies and mis-pricings. With today's many amply capitalized and skilled investors, what are the prospects for a value practitioner? Better than you might expect, for several reasons. First, even with a growing value community, there are far more market participants with little or no value orientation. Most managers, including growth and momentum investors and market indexers, pay little or no attention to value criteria. Instead, they concentrate almost single-mindedly on the growth rate of a company's earnings, the momentum of its share price, or simply its inclusion in a market index. 价值投资依然是少数派

 

Second, nearly all money managers today, including some hapless value managers, are forced by the (real or imagined) performance pressures of the investment business to have an absurdly short investment horizon, sometimes as brief as a calendar quarter, month, or less. A value strategy is of little use to the impatient investor since it usually takes time to pay off. 机构投资者过于重视短期表现

Finally, human nature never changes. Capital market manias regularly occur on a grand scale: Japanese stocks in the late 1980s, Internet and technology stocks in 1999 and 2000, subprime mortgage lending in 2006 and 2007, and alternative investments currently. It is always difficult to take a contrarian approach. Even highly capable investors can wither under the relentless message from the market that they are wrong. The pressures to succumb are enormous; many investment managers fear they'll lose business if they stand too far apart from the crowd. Some
also fail to pursue value because they've handcuffed themselves (or been saddled by clients) with constraints preventing them from buying stocks selling at low dollar prices, small-cap stocks, stocks of companies that don’t pay dividends or are losing money, or debt instruments with below investment-grade ratings. Many also engage in career management techniques like 'window dressing' their portfolios at the end of calendar quarters or selling off losers (even if they are undervalued) while buying more of the winners (even if overvalued). Of course, for those value investors who are truly long term oriented, it is a wonderful thing that many potential competitors are thrown off course by constraints that render them unable or unwilling to effectively compete.人性永恒

Another reason that greater competition may not hinder today's value investors is the broader and more diverse investment landscape in which they operate. Graham faced a limited lineup of publicly traded U.S. equity and debt securities. Today, there are many thousands of publicly traded stocks in the United States alone, and many tens of thousands worldwide, plus thousands of corporate bonds and asset-backed debt securities. Previously illiquid assets, such as bank loans, now trade regularly. Investors may also choose from an almost limitless number of derivative instruments, including customized contracts designed to meet any need or hunch. 投资品种和渠道更多
