Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Amsurg (Nasdaq: AMSG) fell 10% in early trading after the company released earnings and a big sell order hit the market this morning.

So what: Earnings per share actually beat expectations by a penny at $0.43 per share, but someone sold in a rush this morning. A relatively large sell order looks like it crashed through the market at the open, causing shares to drop like a rock. Since then shares have done nothing but climb higher and are nearly back to flat as I am writing.

Now what: Revenue even beat estimates slightly, hitting $184.7 million in the quarter, so I don't see any glaring bad news today. It looks like a rogue trade is what caused the big drop this morning, and if anything shares should have been trading higher based on results. I wouldn't panic on today's move and may even turn a little more bullish after solid results.
