I think this may be normal when a stock basically just dropped the biggest news to date. I saw this happen with another stock basically the day after it acquired a company that was getting ready to take off right before a major uptrend. I think its just MMs putting in ridiculously low bids all day trying to get people to sell their shares which many did but each to his own. I'm keeping all mine. This activity is like the bubbling of the volcano before it erupts IMO.
