Travel booking website Expedia Inc. (EXPE) - Get Report shares were up 1.43% to $150 in premarket trading Wednesday after analysts at Citi upgraded the stock to "buy" from "neutral" with a $178 price target. 

The price target represents a potential 20% upside from the stock's previous closing price. 

The company was upgraded due to Citi's expectation of a mid-year acceleration in growth as well as expectations that Expedia will be able to sustain that higher pace of growth. 

Expedia shares are up more than 30% year to date. 

What's Hot On TheStreet

The stock market may be overvalued: Now may be the time to pay extra attention to red-hot tech stocks such as Apple (AAPL) - Get Report and Facebook (FB) - Get Report . As TheStreet first reported Tuesday afternoon, asset valuations are somewhat "rich" by standard metrics, Federal Reserve Chair Janet Yellen said in London during a conversation about economic issues with British Academy President Lord Nicholas Stern. Yellen's comments on equity valuation and bank strength closely mirrored Fed Vice Chairman Stanley Fischer's from an IMF event held earlier in the day.

The iPhone has changed how you make money: TheStreet's Scott Gamm is out with a piece that will really get you thinking. Apple's iPhone will turn 10 years old on Thursday. The device not only turned Apple into one of the world's most valuable companies, helping to boost its stock price more than 700%, it also changed the way we invest and trade stocks Gamm points out.

In fact, the original iPhone -- and the current versions -- have an internal stocks app, allowing users to check the broader market indexes and individual stock prices. Having this in your pocket was a big deal 10 years ago.

"I think it's actually made the life for a typical investor much easier," Angelo Zino, an analyst with CFRA Research, told TheStreet. "I think they've been able to tap news flows much quicker."
