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 priceline.com (Nasdaq: PCLN) surged more than 10% in early trading, after reporting big gains in fourth-quarter revenue and profit.

So what: Revenue improved 35% to $731.3 million, lower than the $734.9 million Wall Street expected. Investors didn't care. Non-GAAP profit soared more than 70% to $3.40 a share, easily besting analysts' consensus estimate of $3.09.

Now what: Fools have reason to celebrate the results. Today's $32-a-share rally is considerably more than the $23.71 a share for which the stock traded when Fool co-founder David Gardner first recommended it to Motley Fool Stock Advisor members in 2004. The result? A 100% gain on the original cost basis, or what we here in Fooldom call a spiffy-pop.

Should investors expect more pops? Maybe. At the very least, priceline.com's guidance looks good. Management called for year-over-year revenue growth of 29% to 34%, and $2.34 to $2.44 in non-GAAP profit, surpassing the 26.8% and $2.31 Wall Street was expecting.
