I don't have any stats but I have been thinking on this past several months, look at S&P500 Sectors, find all the sectors that 4 of the last 5 years they were either at the bottom or one step from the bottom, as these sectors seem to right after become either at highest or one step from highest returns for year. Make like 10 steps based on returns/losses. It is sort of like "Dogs of the Dow" except I am seeing that if 4 of 5 years on the floor, CEO's get canned and employees get layed off and whatever product starts being sold. But I would wait for basing then could buy at bottoms where risk is lowest, and can hedge and also sell calls while waiting for it to start going up, help offset losses on the Long Puts.
