That's funny... longs say the same thing all the time when securities they own maintain or beat earnings and guidance, and the stock tanks 8 to 10%.... for no reason. Then people say, "Just allowing shorts to cover and big investors to buy cheap."
There are many instances where it never makes any sense to me. But given the bad weather and short holiday season (as the report states), I'd say they did pretty good. Perhaps expectations were much worse.
