Warren Buffett's 1989 letter attaches an essay on his own mistakes to a 23.8%-a-year record, and it supplies the test long-term investors usually lack: how to tell a cheap price from a cheap business.
My first mistake, of course, was in buying control of Berkshire. Though I knew its business — textile manufacturing — to be unpromising, I was enticed to buy because the price looked cheap. Stock purchases of that kind had proved reasonably rewarding in my early years, though by the time Berkshire came along in 1965 I was becoming aware that the strategy was not ideal. If you buy a stock at a sufficiently low price, there will usually be some hiccup in the fortunes of the business that gives you a chance to unload at a decent profit, even though the long-term performance of the business may be terrible. I call this the "cigar butt" approach to investing. A cigar butt found on the street that has only one puff left in it may not offer much of a smoke, but the "bargain purchase" will make that puff all profit.Unless you are a liquidator, that kind of approach to buying businesses is foolish. First, the original "bargain" price probably will not turn out to be such a steal after all. In a difficult business, no sooner is one problem solved than another surfaces — never is there just one cockroach in the kitchen. Second, any initial advantage you secure will be quickly eroded by the low return that the business earns. For example, if you buy a business for $8 million that can be sold or liquidated for $10 million and promptly take either course, you can realize a high return. But the investment will disappoint if the business is sold for $10 million in ten years and in the interim has annually earned and distributed only a few percent on cost. Time is the friend of the wonderful business, the enemy of the mediocre. 1
| The mistake | What the letter records | The principle it produced |
|---|---|---|
| Buying a cheap, unpromising business | Berkshire's textile maker, bought in 1965 because "the price looked cheap"; Hochschild Kohn, sold three years later for about what he paid | "It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price." 1 |
| Expecting good managers to fix bad economics | Both Berkshire's textile business and Hochschild Kohn had "able and honest people running them" | "it is the reputation of the business that remains intact" 1 |
| Taking on hard problems | "What we have learned is to avoid them" | "we've done better by avoiding dragons than by slaying them" 1 |
| Assuming managers decide rationally | The four behaviours of the institutional imperative | "Rationality frequently wilts when the institutional imperative comes into play." 1 |
| Working with people he did not admire | "After some other mistakes, I learned to go into business only with people whom I like, trust, and admire." | "We've never succeeded in making a good deal with a bad person." 1 |
| Leaving undone what he already understood | Purchases "served up to me on a platter and that I was fully capable of understanding" | "the cost of this thumb-sucking has been huge" 1 |
| Running Berkshire without conventional leverage — the one he still defends | Higher leverage "would have produced considerably better returns on equity than the 23.8% we have actually averaged" | "A small chance of distress or disgrace cannot, in our view, be offset by a large chance of extra returns." 1 |
