Investors, of course, 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. Indeed, borrowed money has no place in the investor's tool kit.
The optimum portfolio depends on the various expectations of choices available and the degree of variance in performance which is tolerable. The greater the number of selections, the less will be the average year-to-year variation in actual versus expected results. Also, the lower will be the expected results, assuming different choices have different expectations of performance.
Today people who hold cash equivalents feel comfortable. They shouldn't. They have opted for a terrible long-term asset, one that pays virtually nothing and is certain to depreciate in value.

At age 19, I read a book [The Intelligent Investor] and what I'm doing today, at age 76, is running things through the same thought process I learned from the book I read at 19.
One of the ironies of the stock market is the emphasis on activity.

If I were the treasury secretary or head of the Fed, you know, I would try to scare the hell the out of the private sector and say, you better save this because you're going down with the ship.
The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage.
At Berkshire, I both initiate and monitor every derivatives contract on our books ... If Berkshire ever gets in trouble, it will be my fault. It will not be because of the misjudgments made by a risk committee or chief risk officer.
A prediction about the direction of the stock market tells you nothing about where stocks are headed, but a whole lot about the person doing the predicting.
I've read about all the sales today. If you're an auto dealer, you're feeling it. If you're a furniture retailer like we are, you're feeling it. If you're a jewelry retailer, you're feeling it. I know some of these businesses because we're in them. Yeah, it's being felt, but it will be felt big time more if we don't do something about it, what's going on.
I’ve worked in an economy that rewards someone who saves the lives of others on a battlefield with a medal, rewards a great teacher with thank-you notes from parents, but rewards those who can detect the mispricing of securities with sums reaching into the billions.
