Hoping for the next (flash) crash by Warren Buffett

During 1987 the stock market was an area of much excitement but little net movement: The Dow advanced 2.3% for the year. You are aware, of course, of the roller coaster ride that produced this minor change. Mr. Market was on a manic rampage until October and then experienced a sudden, massive seizure. 

 We have "professional" investors, those who manage many billions, to thank for most of this turmoil. Instead of focusing on what businesses will do in the years ahead, many prestigious money managers now focus on what they expect other money managers to do in the days ahead. For them, stocks are merely tokens in a game, like the thimble and flatiron in Monopoly. 

 An extreme example of what their attitude leads to is "portfolio insurance," a money-management strategy that many leading investment advisors embraced in 1986-1987. This strategy - which is simply an exotically-labeled version of the small speculator's stop-loss order dictates that ever increasing portions of a stock portfolio, or their index-future equivalents, be sold as prices decline. The strategy says nothing else matters: A downtick of a given magnitude automatically produces a huge sell order. According to the Brady Report, $60 billion to $90 billion of equities were poised on this hair trigger in mid- October of 1987. 

 If you've thought that investment advisors were hired to invest, you may be bewildered by this technique. After buying a farm, would a rational owner next order his real estate agent to start selling off pieces of it whenever a neighboring property was sold at a lower price? Or would you sell your house to whatever bidder was available at 9:31 on some morning merely because at 9:30 a similar house sold for less than it would have brought on the previous day? Moves like that, however, are what portfolio insurance tells a pension fund or university to make when it owns a portion of enterprises such as Ford or General Electric. The less these companies are being valued at, says this approach, the more vigorously they should be sold. 

As a "logical" corollary, the approach commands the institutions to repurchase these companies - I'm not making this up - once their prices have rebounded significantly. Considering that huge sums are controlled by managers following such Alice-in-Wonderland practices, is it any surprise that markets sometimes behave in aberrational fashion?

 Many commentators, however, have drawn an incorrect conclusion upon observing recent events: They are fond of saying that the small investor has no chance in a market now dominated by the erratic behavior of the big boys. This conclusion is dead wrong: Such markets are ideal for any investor - small or large - so long as he sticks to his investment knitting. 

Volatility caused by money managers who speculate irrationally with huge sums will offer the true investor more chances to make intelligent investment moves. He can be hurt by such volatility only if he is forced, by either financial or psychological pressures, to sell at untoward times. 

 At Berkshire, we have found little to do in stocks during the past few years. During the break in October, a few stocks fell to prices that interested us, but we were unable to make meaningful purchases before they rebounded. At yearend 1987 we had no major common stock investments (that is, over $50 million)other than those we consider permanent or arbitrage holdings. However, Mr. Market will offer us opportunities - you can be sure of that - and, when he does, we will be willing and able to participate.
