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 TAL Education Group (NYSE: XRS) fell 15% today after announcing earnings.

So what: The after-school tutoring services company reported a 47.7% increase in revenue, to $24.1 million in the quarter, as total student enrollment grew 25%. Earnings per American depositary share of $0.03 were what disappointed the market; analysts were expecting EPS of $0.04.

Now what: The company is still growing at a rapid pace, but with a price-to-earnings ratio of 45, earnings will need to pick up if the stock is going to recoup today's losses. This is the first quarter the company has reported earnings as a public company, so the market didn't quite know what to expect today. I'm going to have to leave this move alone and wait for more growth or a better value before buying shares.
