My favorite trick is if you start with 10 funds the first year. The second year kill off the bad ones and merge all the assets in to the good ones. Do this for several years and your funds look like they have really good performance! It is the same as asking everyone to flip a penny in a classroom of 100 students and every time someone gets tails sit down until there is 1 student left. Then take bets on if they will get heads or tails the next time.
