I don't think shorting WFC now is a good idea.
I do wish I had shorted on Feb 11 after not seeing a bounce after a sharp plunge. Had I opened shorts then and just let the profit ride until it started to turn, I could've seen some heavy green... instead, I sat on my hands (because I really don't like shorting and am uncomfortable with it) and saw losses instead of gains.
I can tell you that I'm growing more and more comfortable with the idea of playing shorts more these days.... at least until they put on better regulations. I don't want to apply downward pressure on the markets, but I've about had it with letting others profit on the ride down while I accrue losses.
Hopefully this coming week will be rally city. I'd be thrilled if we've put in a bottom or are near the bottom.. but I'm in a defensive mindset these days and will probably be buying protective puts after the next rally or sequence of rallies, and just rolling them as needed.
