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 large-scale department store Dillard's (NYSE: DDS) are popping 11% today after reporting better-than-expected fourth-quarter results.

So what: For the quarter, Dillard's posted a profit of $2.21, excluding one-time items, on a 3% rise in same-store sales. This compares favorably to Wall Street's consensus EPS estimate of $2.02 for the quarter.

Now what: Everything seems to be clicking for Dillard's, which saw gross margin expand for the year. It also repurchased $98.8 million worth of its shares during the fourth quarter. Interestingly enough this strength doesn't extend to the entire sector, because rival Kohl's (NYSE: KSS) missed the mark with its fourth-quarter earnings results this morning. While not exactly inexpensive, Dillard's appears to have all of the tools in place to keep its momentum moving in the right direction.
