Shares of priceline.com (Nasdaq: PCLN) hit a 52-week high today. Let's look at how the company got here and whether clear skies are ahead.

How it got here
Priceline's recent highs can be attributed as much to a lack of true competition as to international growth. The company, which allows users to book travel and hotel deals online, is now seeing the fruits of its aggressive push into Europe, Asia, and Latin America. With 78% of all revenue derived internationally, Priceline holds a commanding lead over peers Expedia (Nasdaq: EXPE) and Orbitz Worldwide (NYSE: OWW), which generate most of their revenue domestically.

In fiscal 2011, Priceline's net revenue jumped 41%, with net income practically doubling year-over-year to $20.63 per share. Although Priceline may have killed off its negotiator, William Shatner, it appears the legacy of 20%-plus revenue growth is still well intact.

How it stacks up
Let's see how Priceline stacks up next to its peers.

But for all the talk of Priceline's dominance, it's very difficult to wrap my head around its current valuation compared to the rest of the travel services sector. Orbitz had one huge growth year from 2006 to 2007, which skews its five-year growth results (revenue has slowly dropped since then). But Ctrip.com has shown similar strong growth in China, and it's done so with remarkably cheaper metrics, at just a fifth of Priceline's price-to-book and a third of its price-to-cash-flow. Even the slower-growing Expedia looks like a value play, with just 4.4 times cash flow.

What's next
Now for the real question: What's next for Priceline? That answer really depends on whether the company can continue to grow at close to 30% per year, which I feel it needs to do to maintain its current pricey valuation.

Our very own CAPS community gives the company a two-star rating (out of five), with 75% of members who've rated it expecting it to outperform the market. I'm part of the 25% that currently has a CAPScall of underperform on Priceline; unsurprisingly, I'm down 33 points on that pick. Even though I'm currently down, I'm not considering myself out. With considerably cheaper alternatives in Expedia and Ctrip -- as well as the emergence of MakeMyTrip (Nasdaq: MMYT), which has the potential, along with Ctrip, to lure international online bookers away from Priceline -- I don't see how Priceline will be able to maintain its lofty valuation.
