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 electronics and home appliances retailer Conn's (Nasdaq: CONN) surged 18% today after its quarterly results and guidance topped Wall Street expectations.

So what: The company's fourth-quarter beat was so wide -- adjusted EPS of $0.34 versus the consensus of $0.29 -- that analysts have no choice but to raise their growth estimates yet again. Comparable store sales increased 12.1%, while margins continued to improve, suggesting that its turnaround momentum isn't about to slow anytime soon.

Now what: Looking ahead, management now sees 2013 EPS of $1.20-$1.30, up nicely from its prior view of $1.05-$1.15. "We are on track with our store opening plans and are looking forward to returning to unit growth after a period of retrenchment," Chairman and CEO Theodore Wright said. With the stock now up a whopping 270% over the past year and trading at a forward P/E of 15, however, much of that the growth might already be baked into the price.
