My cynical (and unfortunately usually right when it comes to INOC) side says that INOC itself is buying the stock to prop up the price. Look at it this way, whenever the markey looks to tumble on bad news, (UAL today), the volume of this stock shoots up, yet the price still decreases. My theory is that this is the time they are buying back their own sotck to keep the price from falling during these 'bad' days. Thus making them look more solid than they are since they did not drop like the Home Depot and other large stocks did.
Did INOC ever announce a stock buy-back plan? If not, the SEC takes a VERY dim view of any such action. Unless you have some hard evidence, be very careful what you post if it even implies law-breaking. There are folks doing hard time for such posts right here on Yahoo!
