b9, I agree, and your point about a stock's price tending to move to where there's volume is a great one. But y'know what? Back to the "manipulation" theme... even though we both just got finished saying that there's been no manipulation today, this stock has been very thin lately. And obviously traders and market makers make their money by buying and selling (or selling and buying). Sometimes when the trading volume in a stock dries up, it appears that some trader, or group of traders, will hit a few bids (or take out a few offers) to try to guide the stock price into a new trading range, a few cents lower or higher than the previous one, where there will be more volume for them to trade with.
Is that part of what happened this morning? There's no way to tell, but "maybe." Still, I wouldn't call that "manipulation" in the sense of "Let's drive down the price of IMSC!"
