Expedia has been chasing gains to all time highs, but its big play to extend into Asia-Pacific with Wotif's acquisition is hampering the stock. Is a half-billion dollar transaction too much for the former IAC asset to digest? Even then, that comes as other competitors' gains have outstripped Expedia's stock rise. The company is today's Chart of the Day, and it's looking to develop its top line in a new region among a crowded field in the U.S. -- and one that is expected to see more tech companies muscle in on their digital deals. Expedia may need more than M&A to lock in its place in the travel market.
