Guys what's happening with MO Fin Services and VBL?

MO has been falling from 760-770 2 weeks back to 580 today. The company has good fundamentals and even the P/E isn't bad. VBL hasn't seen that kind of a fall but isn't doing very well either. Any idea what's going on? I have MO at 645 avg. Do you think I should fit losses or hold?
