I would agree with you, rinky, in some stocks. But I dont beleive we have the daily volume to make it worth while for this kind of trading. The highly liquid stocks are the most suited for that, IMO.
It could explain the blocks on the ask, but I think that would be stupid of them preventing their money from making more money. If they would leave the stock run, they would be talking 30-40% in a much shorter time frame. IMO, the best way to play with SLI stock, is to buy and hold as much stock as you can until the buyout. Its gonna keep going up, why hold it back?
