In September, Priceline (PCLN) became the first S&P 500 company to hit a four-digit price. Google (GOOG) became the second to achieve the milestone last month. But Google is about 10% below Priceline newest peak of $1,109.50.

Though Priceline is up nearly 80% so far this year, analysts remain bullish. The average price target on Wall Street stands above $1,200 per share, up another 10% from current levels.

While Priceline shares are not cheap, they're not terribly overvalued either for being the leader in online travel. Shares are trading around 21 times 2014 earnings estimates. That makes it more expensive than rival Expedia (EXPE), but the stock is trading at a discount compared to Orbitz (OWW) and TripAdvisor (TRIP).
