Monkey randomly throwing darts are better stock sellers.

New research revealed that the biggest investors in the world don't make the best decisions when selling stocks.

This came to light when an investor's stock selling decision was compared to a strategy which is almost like throwing a dart at a list of names that exist in their portfolio. If their clients had instead hired the monkey with darts to randomly choose which stocks to sell, the client's portfolios would have earned 0.8 percentage points more per year.
