Let me suggest you are at least asking the wrong question and perhaps looking at saving ego as opposed to investing.

Consider these

#1 Anybody who says they have not made stupid mistakes investing, is lying, blind of too inexperienced to listen to.

#2 Being concerned about an investment basis might make for the wealthy, is something accounts like to talk about, and probably of less importance than #3

#3 One should never purchase stocks without a firm basis to expect an adequate return at the purchase price. Just because you thought XYZ as a good deal at $50 is no reason to buy more at $25. Rather spend time figuring out what you did not know when you made the $50 purchase. Maybe the majority of current owners are still buying at $25 and the stock is really only worth $12.50

Regarding RIMM -- I get the feeling it has dropped in price since you bought it -- so what makes you think you know more about that company today than you knew when you first bought? Do you think you know more about the chances for survival than the Wall Street people who work full time and spend tens of thousands on research?
