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 data-center technologist Infoblox (NYSE: BLOX) soared 13% today after its quarterly results and guidance easily topped Wall Street expectations.

So what: The stock has been crushed in recent months on concerns over higher costs, but today's wide first-quarter beat -- adjusted EPS of $0.06 versus Wall Street's break-even forecast -- coupled with extremely upbeat guidance for the full year is quickly easing those worries. Infoblox even saw its revenue spike 26% to $49.5 million during the quarter, giving investors plenty of good vibes over the demand tailwinds working in the company's favor.

Now what: Management now sees 2013 adjusted EPS of $0.17-$0.21 on revenue of $204 million-$208 million, versus the consensus of $0.06 and $199 million. "I believe our results reflect the strength in our comprehensive product portfolio, our competitive position and the market's growing adoption of our automated network control solutions," said CEO Robert Thomas. Given today's massive rally and the stock's still-small and speculative nature, however, I'd remain highly cautious about buying into that bullishness.
