A holder of over 10% has to file an early warning report to indicate their change in share position. What I'm not sure about is the time frame they have to report with in. From what I recall it is in a relatively short time frame after buying/selling the stock. I will check and post. In any event, we'll find out if these "rumors" about a large seller getting out of SGY and LEG are legit. I've searched for early warning reports on SGY and have found none to speak of.
