"We maintain our Buy rating because we believe the company's fundamentals will significantly improve in 2H12 and FY13," Askew said in a report. "Our optimism for the next two years is based on Expedia's technology platform investments which have a proven record of driving higher gross bookings growth."

Askew said he thinks Expedia is "positioned to have a great couple of years" in part based on an upcoming technology upgrade which will allow for faster bookings.

Some of the more positive notes in Expedia's earnings include improvements in international gross bookings.

"Despite concerns of a European slowdown, International gross bookings improved by 15% y/y to $2.48 billion, roughly matching consensus at $2.49 billion, driven by accelerating hotel room-night growth, which improved sequentially from 17% in 3Q to 19% in 4Q," Benchmark analysts wrote in a Feb. 10 report. "Room-night growth remained healthy in both the US and EMEA regions, up in the mid-teens y/y, while APAC recorded higher, accelerating roomnight growth."

Shares of Expedia hit a 52-week high of $34.35. The stock's 52-week low of $18.44 was set on March 2.

Expedia has a forward P/E of 10.86; the average for travel and tourism companies is 23.71. For comparison,

Shares of Priceline.com rose 4.11% to $567.44. Stifel's Askew noted that Greece's improving outlook could have helped lift Priceline's shares to their 52-week high.

"Priceline (PCLN, $540.13, Buy) with its international hotel focus (a market that seems to have remained stable in 4Q11) and lean cost structure is likely immune to thechallenges Expedia faced, although foreign currency volatility has been an issue," Askew wrote in a Feb. 10 report.

Priceline is scheduled to report fourth-quarter earnings on Feb. 27. Analysts, on average, anticipate earnings at $5.05 a share on revenue of $968.32 million.

The travel stock reached a 52-week high Monday of $566.99. The stock's 52-week low of $411.36 was set on Oct. 4.
