In a recent study, Vanguard took a look at the last 30 years worth of data for the Russell 3000 index, which represents the total stock market. They found something remarkable - over the last 30 years, 47% of stocks were unprofitable investments and almost 30% lost more than half their value. They also found, and this is the big one, that 7% of stocks had cumulative returns over 1,000%.But imagine how hard it would have been to identify that winning 7% and concentrate only on those holdings in advance? In his recent post, Michael Batnick takes Vanguard's data and looks at the long-term risk of trying to only hold a small amount of stocks, even if you have the conviction that they are the right stocks. Diversification has a much better track record than randomized collections of larger positions. What are the ramifications of this for portfolio construction? How about investment advice?
