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 high-speed-mobile wireless broadband provider Clearwire (Nasdaq: CLWR) dipped as much as 11% earlier in the trading session after an analyst downgrade.

So what: Before the opening bell, Jefferies downgraded Clearwire to hold from buy, which is what has been responsible for sending the stock into a tailspin -- at least for today. In addition, a mixture of crippling debt levels and Sprint Nextel's (NYSE: S) slow growth rates (Clearwire essentially is tied to Sprint's hip) have put its share price under pressure.

Now what: I usually place little credence in the one-day moves of analyst upgrades and downgrades and would suggest doing the same here as well. Despite being in full agreement with the downgrade, as I find Clearwire's debt level and business prospects to be grim, I feel that nothing has changed materially because of the downgrade; it shouldn't alter your investment thesis on the company.
