I'm not a finance guy, but should this equate to a big rebound in the stock price? It was trading at ~$130 a month ago, then significantly down in the last few days, and now it seems to be at ~$30 in pre-market.
A stock price is representative of the value of expected future earnings. $30 may just already price in those. Since the stock didn't go to zero, it means agents on the market still expect the company to survive and operate at a profit in the future.
I would stay out of bank stocks for a while.

Just wait for the middle of the next Great Depression and invest your money then.
