Hmmm... something else going on?

Stocks plunge; Dow has record drop, then recovers

NEW YORK – The stock market had one of its most turbulent days in history as the Dow Jones industrials fell to a loss of almost 1,000 points in less than half an hour on fears that Greece's debt problems could halt the global economic recovery.

The market's plunge came less than 90 minutes before the end of trading. The Dow's drop was its largest loss ever during the course of a trading day, but it recovered to a loss of 347 at the close. All the major indexes lost more than 3 percent.

There were reports that the sudden drop was caused by a trader who mistyped an order to sell a large block of stock. The drop in that stock's price was enough to trigger "sell" orders across the market.

Hmmm... Rachel tonight reported that several stocks fell to $0/share... while others sky-rocketed (e.g., from ~$35/share to $100,000/share).

So far no one is talking about a cyber-attack on NYSE.
Why not? ... or am I just being paranoid???

Does this look like normal activity to you???
