Friday saw CAAH's largest volume day in five years. I noticed it trading pre-market with about 450,000 shares trading before the open, did some quick dd and picked up 100,000 shares on speculation that something may be in the makes. Don't know if anything will pan out from it, but don't think I'll get hurt from it. The stock normally trades about 100,000 to 150,000 shared per day on average and Friday saw nearly 6 million on no news. Anyone have an idea?
