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 integration software specialist Informatica (Nasdaq: INFA) popped 15% today after its quarterly results and guidance topped Wall Street expectations.

So what: The stock has been hit in recent months on worries over the weak economy, but the fourth-quarter beat -- EPS of $0.47 versus the average estimate of $0.44 -- suggests that those concerns are a tad overblown. More importantly, management sees a strong deal pipeline in the current quarter, giving Mr. Market confidence that those strong results are actually sustainable.

Now what: Looking ahead, management sees first-quarter adjusted EPS of $0.34 on revenue of $187 million-$197 million, while analysts were expecting adjusted EPS of $0.33 on a top line of $195 million. "With the increasingly critical role of our expansive data integration platform and the emerging opportunities driven by the secular megatrends of cloud computing and big data," CEO Sohaib Abbasi said, "Informatica is well-positioned for our long-term growth plans." With the stock still off about 30% from its 52-week highs, there might even be some time to buy into that optimism.
