They like old-world tech because they can move in and out if they are wrong. They fear new tech because of the margin problems at the end of the day and they can't swing around 50,000 shares without wrecking them.

Again, that's textbook. It reminds me of the days when people would buy

Coke

(KO) - Get Report

and

P & G

(PG) - Get Report

right here when the smoke had cleared. Now they buy

Cisco

(CSCO) - Get Report

,

Intel

(INTC) - Get Report

TheStreet Recommends

and

Sun Micro

(SUNW) - Get Report

and

Oracle

(ORCL) - Get Report

.

Most of you are individuals. You don't know what it is like to try to swing 50,000

MediaPlex

(MPLX) - Get Report

. You can't get it done. It can't be done. So you go buy what you can buy: old tech.

Reminder: Don't get too cocky about the long side -- lots of people want out and need to be out. It won't be a whoosh back up.
