and he had done it for 47 years (maybe not every year, but compound annual return), that’s pretty good.
The following is quoted from Buffett 2006 shareholder letter, you can get the full letter at Berkshire web site:
Let me end this section by telling you about one of the good guys of Wall Street, my long-time friend Walter Schloss, who last year turned 90. From 1956 to 2002, Walter managed a remarkably successful investment partnership, from which he took not a dime unless his investors made money. My admiration for Walter, it should be noted, is not based on hindsight. A full fifty years ago, Walter was my sole recommendation to a St. Louis family who wanted an honest and able investment manager.
Walter did not go to business school, or for that matter, college. His office contained one file cabinet in 1956; the number mushroomed to four by 2002. Walter worked without a secretary, clerk or bookkeeper, his only associate being his son, Edwin, a graduate of the North Carolina School of the Arts. Walter and Edwin never came within a mile of inside information. Indeed, they used “outside” information only sparingly, generally selecting securities by certain simple statistical methods Walter learned while working for Ben Graham. When Walter and Edwin were asked in 1989 by Outstanding Investors Digest, “How would you summarize your approach?” Edwin replied, “We try to buy stocks cheap.” So much for Modern Portfolio Theory, technical analysis, macroeconomic thoughts and complex algorithms.
Following a strategy that involved no real risk – defined as permanent loss of capital – Walter produced results over his 47 partnership years that dramatically surpassed those of the S&P 500. It’s particularly noteworthy that he built this record by investing in about 1,000 securities, mostly of a lackluster type. A few big winners did not account for his success. It’s safe to say that had millions of investment managers made trades by a) drawing stock names from a hat; b) purchasing these stocks in comparable amounts when Walter made a purchase; and then c) selling when Walter sold his pick, the luckiest of them would not have come close to equaling his record. There is simply no possibility that what Walter achieved over 47 years was due to chance.
For the record, Buffett did beat S&P 500 for 42 years (if you read its 2006 annual letter), his Berkshire annual return is 21.4% from 1965 to 2006, vs. 10.4% for S&P 500. Although they have different business model, Walter’s partnership is more like a mutual fund, while Buffett’s Berkshire is a holding company, both are very impressive indeed.
