Separately, TheStreet Ratings has set a "hold" rating and a score of C on SINA Corp. stock. The primary factors that have impacted the rating are mixed - some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks.

The company's strengths can be seen in multiple areas, such as its increase in net income, revenue growth and expanding profit margins. However, as a counter to these strengths, we find that the company's return on equity has been disappointing.
