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 for-profit educator Bridgepoint Education (NYSE: BPI) jumped more than 10% in intraday trading Tuesday as investors cheered the company's quarterly results.

So what: Bridgepoint said its first-quarter profit climbed 61% on strong enrollment growth and issued full-year guidance that also topped analyst expectations. Unfortunately, shares of Corinthian Colleges (Nasdaq: COCO) are falling big today because it couldn't buck the industry downtrend of shrinking student starts and posted a worse-than-expected profit.

Now what: If you just need to profit from all of the for-profit education carnage, Bridgepoint is likely one of your safest bets. Unlike Corinthian and industry leader Apollo Group (Nasdaq: APOL), Bridgepoint hasn't reported new-student enrollment declines recently, and, given its former students' strong track record of debt repayment, shouldn't be hit too hard by tighter regulation. With the stock still off 40% from its highs in April, there seems to be plenty of upside to make that bet.
