FWIW on level II during the last half hour's run up SCHB was the high bid almost the entire time. SCHB has now backed off a bit so let's see if the price action cools a bit too. Same thing happened about 4 days ago on a run up. On the surface it sure looks like SCHB has a big buyer who comes in every few days to accumulate. Anyone else notice this action or have thoughts on it?
On edit: SCHB's back on top and the buying pressure is picking up again after about a 5 minute breather.
