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 construction equipment provider RSC Holdings (NYSE: RRR) jumped 10% higher today after the company increased guidance.

So what: Revenue is expected to be between $337 million and $340 million, above analysts' expectations of $320 million. Higher rates and volume are helping push revenue higher.

Now what: No word on whether this will keep RSC from reporting a loss as expected, but the higher revenue has to be seen as a good sign. With that said, the $2 billion in long-term debt and expectation of only a slight profit in 2011 leave RSC too high in the risk column for this Fool. At the risk of missing out on yet another pop, I'll leave shares alone today.
