Given the predilection of the market to go higher over the course of the last 200 years, I try to start each day by crafting a thesis on what would get the market moving up.

The pastiche for today goes something like this: Positive

EMC

(EMC)

and

IBM

(IBM) - Get Report

announcement that will be viewed as good for both companies;

3Com

(COMS)

not as bad as expected and should trade up;

The New York Times

writes a visionary piece on

Cisco's

(CSCO) - Get Report

Internet telephony strategy.

Look, it's a start. I didn't say it would hold up.

Why bother being optimistic at all? Why not just side with the bears and sell the whole market short, banging out stocks left and right?

Couple of reasons:

    That's not what got me here. We have had many big down days followed by not-so-big down days and then bottoms. By recognizing that pattern, I have made a lot more money than I have lost. Inflation remains low; the economy is strong. The economic backdrop remains too positive to go short big. Things are no worse than they were a couple of weeks ago. I have detected no further deterioration in tech, which is the blood pressure of this market. The negativity is pretty great. It is incredible how quickly the Dow 9000 crowd reasserted itself in the last 48 hours. We have a ton of stocks that have gotten crushed here, some to the point that they are no longer absurdly valued.

Again, I am not holding cyberhands here. I am just trying to assess today's temperament vs. yesterday's. Gotta do that every day to stay in the game.
