I didn't see your post in time, but buying a stock the day before XD date to take advantage of the div is a non viable strategy.  Go back over some charts and you will notice that on XD date the value of the stock generally loses value equal to the dividend amount.  In some cases the drop will knock the wind out of the stock for some period of time, other times the price will recover soon after - there is no general pattern to the recovery characteristics.

However, it is a viable strategy to consider buying a stock a few weeks before XD date.  In many cases the stock will rise before the XD date, and it is possible to exit either the day before XD, or take the dividend and see if the stock will go up again soon after.  If the stock continues to fall after the div date and hits the stop loss, then the capital gain may be some where around break even, but the dividend is in the bank.
