when GM announced to withdraw its case from bankruptcy last week and will pay back millions of $$ of debt to Gov. by 2015 so i thought to invest some money., i purchased some GM shares under its symbol GMGMQ, there was trading going until Thursday July 9th 2009 , but since July 10th there has been no trading, Does anyone knows about this? Should i sell my Gm shares?? Is there any risk? Also there has been no news since Friday about this.
