When Hypothetical Becomes Real

By Jack Forehand (@practicalquant)

The day you begin to follow a new investment strategy is typically a day of optimism. You have done your research, you have looked at the historical results, you believe in the investment process, and you expect to see similar returns in the future to what the strategy has done in the past.
