We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it. In stating this opinion, we define risk, using dictionary terms, as “the possibility of loss or injury.

Over the years, Charlie [Munger, Berkshire Hathaway Vice Chairman] and I have observed many accounting-based frauds of staggering size. Few of the perpetrators have been punished; many have not even been censured. It has been far safer to steal large sums with pen than small sums with a gun.

We need a moderately-priced stock market… The market, like the Lord, helps those who help themselves. But, unlike the Lord, the market does not forgive those who know not what they do. For the investor, a too-high purchase price for the stock of an excellent company can undo the effects of a subsequent decade of favorable business developments.

financial markets will become divorced from reality — you can count on that. More Jimmy Lings will appear. They will look and sound authoritative. The press will hang on their every word. Bankers will fight for their business. What they are saying will recently have “worked.” Their early followers will be feeling very clever. Our suggestion: Whatever their line, never forget that 2+2 will always equal 4. And when someone tells you how old-fashioned that math is — -zip up your wallet, take a vacation and come back in a few years to buy stocks at cheap prices.

My old boss, Ben Graham, told me very early on you get more trouble with a good idea than a bad idea, because the good idea works. I mean, it's a good idea to buy a home, for example. And then people go crazy sometimes. The good idea works, and it works, and it works. Stocks work out better than bonds most of the time. And, after a while, people forget that there were some other limiting conditions. With Edgar Lawrence Smith's book, it was that when bonds yield the same as stocks — which was the case then — the stocks are going to outperform because they have this retained earnings. So stocks started going up in the Twenties and all of a sudden they were selling at 5 or 6 times the prices as when they bought the book. And the original correct perception on his part had experienced changing conditions, but people ... got their confirmation through stock prices. That's what happens in bull markets. People start out thinking stocks are cheap, and then they start thinking stocks have gone up. And, a stock can be a good buy or a bad buy. A bond can be a good buy or a bad buy. It depends on price.

Focus on the Forest — Forget the Trees Investors who evaluate Berkshire sometimes obsess on the details of our many and diverse businesses — our economic “trees,” so to speak. Analysis of that type can be mind-numbing, given that we own a vast array of specimens, ranging from twigs to redwoods. A few of our trees are diseased and unlikely to be around a decade from now. Many others, though, are destined to grow in size and beauty.

He is also experienced. Though I don’t know Ralph’s age, I do know that, like many of our managers, he is over 65. At Berkshire, we look to performance, not to the calendar. Charlie and I, at 71 and 64 respectively, now keep George Foreman’s picture on our desks. You can make book that our scorn for a mandatory retirement age will grow stronger every year.

I happen to have a talent for allocating capital. But my ability to use that talent is completely dependent on the society I was born into. If I'd been born into a tribe of hunters, this talent of mine would be pretty worthless. I can't run very fast. I'm not particularly strong. I'd probably end up as some wild animal's dinner. But I was lucky enough to be born in a time and place where society values my talent, and gave me a good education to develop that talent, and set up the laws and the financial system to let me do what I love doing — and make a lot of money doing it. The least I can do is help pay for all that.

Trumpeting EBITDA (earnings before interest, taxes, depreciation and amortization) is a particularly pernicious practice. Doing so implies that depreciation is not truly an expense, given that it is a “non-cash” charge.

Imagine, if you will, that at the beginning of this year a company paid all of its employees for the next ten years of their service (in the way they would lay out cash for a fixed asset to be useful for ten years). In the following nine years, compensation would be a “non-cash” expense — a reduction of a prepaid compensation asset established this year. Would anyone care to argue that the recording of the expense in years two through ten would be simply a bookkeeping formality?
