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: Cabela's (NYSE:CAB) shot perfect once again this quarter, as shares jumped as much as 18% after another strong report.

So what: The sportsmen's outfitter topped earnings estimates by $0.11 a share, posting $0.70 for the period, and revenue jumped a whopping 28.7% to $802.5 million, 4% better that expert's prediction. The vast majority of additional revenue came from same-store sales, which shot up 24%. Management said the growth was driven by expected increases in firearms and ammunition sales, as well as soft goods, footwear, optics, and archery.

Now what: Without firearms and ammunition, same-stores sales increased just 9% -- still strong, but clearly much of Cabela's growth was driven by gun buyers. With the gun hysteria following the Sandy Hook shootings likely to fade now that the Senate has failed to pass any sort of gun control, investors may expect that growth to slow. As the stock has now tripled in the past year and a half, investors may want to take a cue from their senators and sell while the stock is hot.
