SINA Corporation provides online media and mobile value-added services (MVAS) in the People's Republic of China. It provides advertising, non-advertising, and free services through SINA.com, Weibo.com, and SINA Mobile. TheStreet Ratings rates SINA as a hold. The company's strengths can be seen in multiple areas, such as its compelling growth in net income, revenue growth and largely solid financial position with reasonable debt levels by most measures. However, as a counter to these strengths, we find that the stock has had a generally disappointing performance in the past year. You can view the full SINA Ratings Report.
