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 Puerto Rican bank Popular (NASDAQ:BPOP) climbed 10% today after its quarterly results easily topped Wall Street expectations.

So what: Popular's fourth-quarter beat was so wide -- EPS of $0.81 versus the consensus of just $0.51 -- that analysts have no choice but to raise their valuation estimates yet again. Additionally, the company's non-performing loans continue to decline while its capital ratios improve, giving investors plenty of good vibes over its financial health going forward.

Now what: Don't let today's pop keep you from looking into the stock. "In 2013, we remain focused on driving value through further progress on all these fronts and continuing to increase our strategic and financial flexibility," said Chairman and CEO Richard Carrion. So while the stock's strong performance of late should give Fools some pause, Popular's still-paltry price to book of 0.6 suggests there's plenty of room to run.
