11000 different stock in a little over a year? Wow.
Keep in mind that the lists change every day (and sometimes intraday). If you don't have the list for each day, the results may not be accurate, particularly considering you are probably shorting stocks that are "in play".
Well put. The stocks were not just "in play" stocks but covered a wide spectrum so i think its representative. However, i agree about the limitation that the lists change daily and so these results should be taken with a few grains of salt.
