If Gump is correct that the KATX million share purchases each business afternoon are the MM's covering KATX shorts before the new rules take effect on 2-28-2011, then on 3-1-2011 and after 3-1-2011 the million share purchases each business afternoon should cease. It is only an advantage to the MM's to make such purchases up til 2-28-2011. After that date the rule changes would make it pointless.
If, on the other hand, the million share purchases each business afternoon continue on and after 3-1-2011, then Gump's theory is most likely in error. So let's see what happens regarding the million share purchases of KATX stock on 3-1-2011 and after. This should be interesting to watch.
