Warren Buffett: 10 percent or greater

“I will bet you that a lot of years in the future we, or you, will be able to find equities that you understand, or we understand, and that have the probability of returns at 10 percent or greater. Now, once you find a group of equities in that range, and leaving aside the problem of huge sums of money, which we have, then we just buy the most attractive. That usually means the ones we feel the surest about, I mean, as a practical matter. There’s just some businesses that possess economic characteristics that make their future prospects, far out, far more predictable than others. There’s all kinds of businesses that you just can’t remotely predict what they’ll earn, and you just have to forget about them. So, we have, over time, gotten very partial to the businesses where we think the predictability is high. But we still want a threshold return of 10 percent, which is not that great after-tax, anyway.” –Warren Buffett (2003).
