very interesting indeed. that has been the pattern these last couple of very high volume days. it is typically not the pattern on a Friday close given the risk averse (i.e., the weekend) nature if investors. The last half hour will determine whether investors actually perceive the greater risk to be: out of the stock ahead of the weekend, that is not positioned before the opening of trading on Monday.
Each day you have been able to get stock, but you have had to pay a little more for it. But you could get it. At some point, one wonders if you have to pay more than "a little more" to get it. Guess we will see.
