延續之前的例子﹕我們估計該項商品的價格將會在由$100升到$200。正確的話,將獲利$50,000 ($100 x 500)。犯錯呢?早前決定了,我們將損失限制在$10,000 ($20 x 500)。類似這樣的投資判斷,我們正確的機會有多少?假設長期下來,我們正確的機率有四分之一(25%,即四次買賣便碰了三次釘),期望值是否為正數呢?計算一下﹕
Take the probability of loss times the amount of possible loss from the probability of gain times the amount of possible gain. That is what we're trying to do. It is imperfect but that's what it's all about. ¹⁰ — Warren Buffett
You can't control luck, but you can move from a game with bad odds to one with better odds. You can make it easier for luck to find you. The most useful thing you can do is stay in the game. Keep repeating until something lucky happens. — Scott Adams
