Expedia ( EXPE - Get Report) has been upgraded by TheStreet Ratings from hold to buy. The company's strengths can be seen in multiple areas, such as its revenue growth, reasonable valuation levels, expanding profit margins, good cash flow from operations and increase in stock price during the past year. We feel these strengths outweigh the fact that the company has had sub par growth in net income.
