- Borrowed money has no place in the investor's tool kit: Anything can happen anytime in markets. And no advisor, economist, or TV commentator--and definitely not Charlie nor I--can tell you when chaos will occur. Market forecasters will fill your ear but will never fill your wallet.
- Investors can, by their own behavior, make stock ownership highly risky. And many do. Active trading, attempts to 'time' market movements, inadequate diversification, the payment of high and unnecessary fees to managers and advisors, and the use of borrowed money can destroy the decent returns that a life-long owner of equities would otherwise enjoy.
- Stock prices will always be far more volatile than cash-equivalent holdings. Over the long term, however, currency-denominated instruments are riskier investments—far riskier investments--than widely-diversified stock portfolios that are bought over time and that are owned in a manner invoking only token fees and commissions. That lesson has not customarily been taught in business schools, where volatility is almost universally used as a proxy for risk.
- In the world of business, bad news often surfaces serially: You see a cockroach in your kitchen; as the days go by, you meet his relatives.
- At Berkshire, we much prefer owning a non-controlling but substantial portion of a wonderful company to owning 100% of a so-so business. It's better to have a partial interest in the Hope Diamond than to own all of a rhinestone.
Our flexibility in capital allocation--our willingness to invest large sums passively in non-controlled businesses--gives us a significant advantage over companies that limit themselves to acquisitions they can operate. Our appetite for either operating businesses or passive investments doubles our chances of finding sensible uses for Berkshire's endless gusher of cash.
- Who has ever benefited during the past 238 years by betting against America? If you compare our country's present condition to that existing in 1776, you have to rub your eyes in wonder. In my lifetime alone, real per-capita U.S. output has sextupled. My parents could not have dreamed in 1930 of the world their son would see. Though the preachers of pessimism prattle endlessly about America's problems, I've never seen one who wishes to emigrate (though I can think of a few for whom I would happily buy a one-way ticket).
- A sound insurance operation needs to adhere to four disciplines. It must
(1) understand all exposures that might cause a policy to incur losses;
(2) conservatively assess the likelihood of any exposure actually causing a loss and the probable cost if it does;
(3) set a premium that, on average, will deliver a profit after both prospective loss costs and operating expenses are covered; and
(4) be willing to walk away if the appropriate premium can't be obtained.
Many insurers pass the first three tests and flunk the fourth.
