RE:volitilityIn all honesty, holding over the weekend is risky to say the least. Monday morning could be like today, it's pretty volatile right now and most people jumped ship to lock in profits a drop of almost 30% is not easy on the stomach especially when everyone links aya with it.
As far as I know "it" is not under investigation but all similar stocks took a hit today. Most people who jump ship will buy back in as soon everything is brough out to the open and probably at lower price.
