Lehman is showing some good resistance at around $0.18-0.19, but it did dip to the low $0.15 (Might have hit less) today. It might still have good potential to go to above $0.50, but it's a very risky move.
Note: I got in MTLQQ when the ticker was still GM and later changed to GMGMQ. I was going to sell it when it went above $1, but I kept it just for the hell of it.
