Ben Graham

Ben Graham taught me that the key to successful investing was the purchase of shares in good businesses when market prices were at a large discount from underlying business values. The true investor welcomes volatility. Ben Graham explained this in Chapter 8 of The Intelligent Investor. There he introduced "Mr. Market," an obliging fellow who shows up every day to either buy from you or sell to you, whichever you wish. The more manic-depressive this chap is, the greater the opportunities available to the investor. That's true because a wildly fluctuating market means that irrationally low prices will periodically be attached to solid businesses. It is impossible to see how the availability of such prices can be thought of as increasing the hazards for an investor who is totally free to either ignore the market or exploit its folly.

Ben Graham told a story 40 years ago that illustrates why investment professionals behave as they do: An oil prospector, moving to his heavenly reward, was met by St. Peter with bad news. “You’re qualified for residence”, said St. Peter, “but, as you can see, the compound reserved for oil men is packed. There’s no way to squeeze you in.” After thinking a moment, the prospector asked if he might say just four words to the present occupants. That seemed harmless to St. Peter, so the prospector cupped his hands and yelled, “Oil discovered in hell.” Immediately the gate to the compound opened and all of the oil men marched out to head for the nether regions. Impressed, St. Peter invited the prospector to move in and make himself comfortable. The prospector paused. “No,” he said, “I think I’ll go along with the rest of the boys. There might be some truth to that rumor after all.”

We bought all of our Washington Post Company holdings in mid-1973 at a price of not more than one-fourth of the then per-share business value of the enterprise. Calculating the price/value ratio required no unusual insights. Most security analysts, media brokers, and media executives would have estimated WPC’s intrinsic business value at $400 to $500 million just as we did. And its $100 million stock market valuation was published daily for all to see. Our advantage, was attitude: we had learned from Ben Graham that the key to successful investing was the purchase of shares in good businesses when market prices were at a large discount from underlying business values.

Most institutional investors in the early 1970s, on the other hand, regarded business value as of only minor relevance when they were deciding the prices at which they would buy or sell. This now seems hard to believe. However, these institutions were then under the spell of academics at prestigious business schools who were preaching a newly-fashioned theory that the stock market was totally efficient. Under the EMT, calculations of business value and even thought, itself were of no importance in investment activities. We are enormously indebted to those academics: what could be more advantageous in an intellectual contest.

Through 1973 and 1974, WPC continued to do fine as a business, and intrinsic value grew. Nevertheless, by yearend 1974 our WPC holding showed a loss of about 25%, with market value at $8 million against our cost of $10.6 million. What we had thought ridiculously cheap a year earlier had become cheaper as the market, marked WPC stock down to well below 20 cents on the dollar of intrinsic value.

Berkshire will someday again have opportunities to deploy major amounts of cash in equity markets -- we are confident of that. But, as the song goes, "Who knows where or when?" Meanwhile, if anyone starts explaining to you what is going on in the truly-manic portions of this "enchanted" market, you might remember still another line of song: "Fools give you reasons, wise men never try."
