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: QuinStreet (Nasdaq: QNST) popped 14% in intraday trading today after reporting inline earnings and reiterating its average revenue growth target of 15% to 20% annually.

So what: Third-fiscal-quarter non-GAAP EPS of $0.25 grew 19% from the year-ago quarter and met the consensus estimate of $0.25. Revenue grew 19% year-over-year as well, with growth of 26% in the Education vertical. There were concerns about Education because QuinStreet's 2010 IPO filing indicated that DeVry (NYSE: DV), which accounted for 19% of 2009 sales, had recently retained an ad agency and cut back its business with QuinStreet. 

Now what: The company's Education clients are for-profit companies such as DeVry and Apollo Group (Nasdaq: APOL), which are challenged by declining enrollment and criticism that they fail to adequately train students. Those challenges appear to be working in QuinStreet's favor. Management indicated that Education client demand was benefiting from demand for "more compliant and effective marketing solutions," as well as the addition of new customers and an increase in business with existing customers.
