Sounds like a guy who has shorted the market and wants to make his predictions come true.
It's also possible that he's in the lucky-guess business. By that I mean he makes a rather specific guess as to market direction.
If he's right, jackpot! There will be book tours, interviews on financial shows, investment newsletters to sell, etc. And if he's wrong, just hang back for awhile until people forget the wrong prediction.
More likely that Buffett and Soros have shorted the market and Obama is making it happen. McClellan probably is aware of it and is sharing the info.
McClellan reads charts. The writing is on the wall.
And as Forrest Gump says, “that’s all I have to say about that” (especially since I’m saying more than I actually know.)
