Don't worry, you will be able to get back in below $3.
Every so often some crazy rumor gins up a bunch of hope for SIRI and the price goes up to $3.25 or so....it ALWAYS comes back down.
I also sold today, @3.21. It was the first time I was in the green in a long time. I understand it was a large risk but, I intend to buy back in increments during what I hope is one more drop prior to the merger.
It's a odd feeling after hoping for good news all this time, now I have to look for a drop. :-) If it works out the added accumulation of shares I get will pay off as I am looking very long term.
