On the Dow Closing at 8000

UPDATE: Oops. It's a dynamic chart. I mean really dynamic. This morning it was the DIA from Jan. 30. It seems to have transformed itself into the S&P E-Mini futures chart. Clicking the link gets you the DIA, but it's Feb. 2 prices. Interestingly enough there was another gap up in the last half-hour.

As a followup to Friday's "The Grassy Knoll Theory of Investing" a commenter at The Big Picture's "8000 Open Thread" points out:

30-min chart shows 3 million shares of the Diamonds (DIA) at the close to make sure 8000 held!
