I said they can only trade 3 days after reporting till end of quarter. It actually is 3 days after reporting until 1 week BEFORE quarter ends AND they can not have any non-public marketing moving information.
So the trading window is shorter by 1 week than I actually said. Any shenanigans on the Russell rebalance day had nothing to do with insiders as the window was closed for 1 week already
so this next trading window is potentially only two weeks long. They have reported in the past the 1 first week in Sept. The window would open on Sep 9 and close Sep 23. Hence, why they would want to trade this quarter
