In The Unemotional Investor, Robert Sheard, author of the Dow Dividend Approach and Foolish Workshop for The Motley Fool, offers a way around this dilemma. He notes that the obvious requirement for making money in the stock market is to buy low and sell high, but that most people simply can't do this. What
does it take to buy low and sell high? Surprisingly enough, it takes the polar opposite of normal human emotions.

So rather than try to reverse this investor psychology, Sheard sidesteps it altogether and advances two successful systems for buying and selling stocks. The first follows the Dogs of the Dow, which looks at the highest yielding stocks in the Dow 30. The second invests in growth stocks that also have a high degree of price momentum. Both systems require no knowledge of the companies in which you're investing. Instead, decisions to buy and sell are based on easily-acquired information. Sheard demonstrates how over the years these systems have consistently beaten--by a wide margin--all of the major markets.
