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.
Warren BuffettI like to go for cinches. I like to shoot fish in a barrel. But I like to do it after the water has run out.

Warren BuffettWell, one time some attractive woman sat next to Charlie and asked him what he owed his success to, and, unfortunately, she insisted on a one word answer. He had a speech prepared that would have gone on for several hours. But when forced to boil it down to one word, he said that was "rational". You know, he comes equipped for rationality, and he applies it in business. He doesn't always apply it elsewhere, but he applies it in business and that has made him a huge business success.
Warren BuffettIf you aren't willing to own a stock for ten years, don't even think about owning it for ten minutes. Put together a portfolio of companies whose aggregate earnings march upward over the years, and so also will the portfolio's market value.
