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 radio frequency solution provider TriQuint Semiconductor (Nasdaq: TQNT) have been beaten up today, falling 28%, after the company released earnings.

So what: During the third quarter, revenue fell 9% to $216 million, $2 million more than analysts were expecting, and adjusted earnings per share beat estimates by a penny at $0.11.

Last quarter was good, but demand for the fourth quarter looks to be lower than expected. Management expects revenue between $215 million and $225 million, while earnings per share should be between $0.06 and $0.08 per share. Analysts expected fourth-quarter earnings of $0.14 per share on revenue of $232 million.

Now what: It's rough when a company's earnings beat expectations and the stock still takes a beating like this. But in this age of uncertainty, what you're going to do for me tomorrow is more important than what you did for me yesterday. I am staying away from a drop like this because when the market reacts this violently downward, you never know when the bleeding is going to stop.
