I have one fella in my office here, who purchased SIRI at $2.20, and held up to $8 or so. Never sold a share as it dropped below $6/share. After we had a few conversations he stated "I hope it falls below $4.50 so I can buy more" and "I'm not selling until it gets to $25/share".
I just let him know that his $4.50 wish has come true.
