I have noticed that if you buy a stock on the day of the split, which is the "ex date" and hold on to it a few months, it will almost always rise a significant percentage, much more than the market in general. One caveat is that the stock must split at least 2 to 1. I will comment on them and let you see how this works. I have back tested it each month with the 15 or so stocks that split and it works great. Any comment are welcome. Buy on Monday: CELG and EXP. On Wed: CNI and PPDI.
