ti was definitely strange tape today. It's hard to say what really happened, but there was certainly an element of manipulation involved, possibly fraudulent. It doesn't really make any difference one way or the other - the whole market is manipulated, and somebody with lots of money was seriously focused on CTIC and ONVO (awesome bear raid today). The important thing, when you play the market, is to understand that everything you read or get fed about an event relating to a stock is BS designed to support an interest, usually in conflict.
In all fairness, the fact that CTIC has 128M shares in the float and a market cap of $228M doesn't strengthen the stock - rather makes it an easy target when organized funds want to cut their losses on naked shorts, or accumulate on news. You're going to have to hold this one for a while to make a few bucks, tho the short term future looks bright.
