Traders, when you trade

Electronic Arts

(ERTS)

, chill out before you pull the trigger. Take a deep breath. Heck, take some Xanax, that's got anti-panic applications.

Here's the drill.

Last night, Electronic Arts was due to report. I don't know a soul who believed it would be a good number or a soul who believed that guidance would do anything but go down big. This was not, by the way,

Qualcomm

(QCOM) - Get Report

, where we all knew last quarter. There was simply no way, given the shipping schedule, that EA could do the quarter or the year.

Yet, when it reported the disappointing number and the lowered guidance, there was a mass freakout, a total panic, one that took the stock down to the mid-$50s, for heaven's sake. That's just stupid, that's terrible trading. That's uninformed people getting slaughtered.

Today it's right back, probably will finish up on the session. It's a reminder to me how few people are still doing

homework. If you had read any notes or talked to anyone who followed this stock, it was right on script.

If you are going to trade these big mutual-fund stocks, get your metrics right. Know what to look for. And if you get it, don't panic and sell. And don't panic and buy. Wait.

And then pounce when the other guy gets it wrong. Lots of people are getting a lot of things wrong these days.

Don't be fooled.
