Seeing as it was an Etrade Ask Order my thought may not be so strong/realistic, but seeing as Trading appeared to be so tightly controled all afternoon, I was thinking the $2.03 buyer at the close may have pulled their $2.01 Wall just prior to making the Closing Buy. One many need not have all their Eggs (cash) in one Broker Account. In fact, given the nature of the Financial Industry these days, DIVERSITY of Accounts/Brokers is a good manner of keeping from jepordising ones' Wealth by having it all under one Roof.
But one thing is clear. The intention was to have the SP close on the up and at the day High, and at the End of the day, and that day being a Friday, and at the END of a HELL of a week, and only one week prior to the Tripple Whitching Friday.... Fluke???
