Did stocks rise 494 points on the Geithner bounce?

There is no way to know why stocks go up or down every day. That's why I always find it somewhat silly when I see simple explanations for the movement in prices. The explanation offered for today's 494 point rise is that investors are celebrating the rumor that Timothy Geithner will be the next Treasury Secretary. How does the media know that investors are only celebrating Geithner's appointment and not that of Bill Richardson as Commerce Secretary?

Make no mistake. I agree with the choice of Geithner and made a case for him over former Harvard president, Lawrence Summers, and former Fed Chair Paul Volcker. My reasoning for Geithner was that he had excellent interpersonal skills and high energy coupled with an intimate familiarity with the current financial crisis. Unlike Summers, Geithner is highly unlikely to alienate people, and having picked Hillary Clinton as Secretary of State, President-elect Obama will have enough drama on his hands with both Clintons.

Geithner shares something with current Treasury Secretary Hank Paulson -- he graduated from Dartmouth. I hope that he makes far better use of that Ivy League education in the Treasury Secretary's role than his predecessor. While Geithner will be left with a huge mess that was not helped by his fellow Dartmouth alum, it will be difficult for him to do a worse job than Paulson. The world will be depending on him.
