TheStreet Ratings team rates BAIDU INC as a Buy with a ratings score of B. TheStreet Ratings Team has this to say about their recommendation:
"We rate BAIDU INC (BIDU) a BUY. This is driven by some important positives, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its robust revenue growth, growth in earnings per share, largely solid financial position with reasonable debt levels by most measures, solid stock price performance and expanding profit margins. Although the company may harbor some minor weaknesses, we feel they are unlikely to have a significant impact on results."
