Shares of SINA Corporation (NASDAQ: SINA) were down 12% as of 11:45 a.m. EST Thursday, despite strong fourth-quarter 2016 results from the Chinese internet-media company.

So what

Adjusted quarterly revenue rose 23% year over year, to $310.8 million, including a 20.8% increase in online advertising revenue, to $269.6 million. Within the latter figure, advertising and marketing revenue from Weibo jumped 45%, to $187.9 million, more than offsetting a 23% decline in portal ad revenue, to $31.3 million. On the bottom line, adjusted net income nearly doubled, to $48.2 million, while adjusted net income per share rose 80% year over year, to $0.63.

By comparison, analysts' consensus estimates predicted SINA would turn in lower adjusted revenue of $301.6 million, and adjusted earnings of only $0.55 per share.


Now what

Assuming exchange rates remain steady, SINA anticipates adjusted revenue for the full year of 2017 to be between $1.30 billion and $1.44 billion, which was also significantly above the $1.27 billion investors were expecting.

So why the decline? For one, keep in mind that even after today's drop, shares of SINA are still up more than 60% over the past year. So perhaps some investors are taking profits off the table in spite of SINA's relative outperformance this quarter.

And to be fair, SINA still has work to do in continuing to better monetize the growing mobile user base of its weaker portal business. But even then, management insisted during the subsequent conference call that its portal advertising business has "very much stabilized," and should continue to improve as we get deeper into 2017.

In short, sometimes our fickle market's reaction to earnings simply doesn't line up with what's actually happening in the business. In SINA's case, I think this could ultimately prove to be a compelling opportunity for patient investors to open or add to their positions.
