Today's most unfortunate soul was

Networks Associates

(NETA)

, which provides network security solutions and issued an earnings warning postclose. The company said it expected a net loss of $130 million for the fourth quarter and announced the resignation of several key executives, including the president and CFO. The stock was crushed in after-hours action, saying goodbye to a double-digit stock price. It lost $5.63 to $6.19 on 177,000

shares. The stock traded an additional 35,000 shares on

Island

.

Liquidity is a curious thing. When there's lots of it -- such as in a stock like

General Electric

(GE) - Get Report

on the day it releases earnings -- stocks are hard to move around, and even with all the frenzied trading, there's a certain order to the mountainous volumes of trades that move through the market.

On the other hand, there are times when liquidity is at a premium, such as after-hours during the week between Christmas and New Year's Day, the quietest week of the year for trading. And a stock with a little bit of news can just explode in your face.

Take

(RGIS)
