So what

58.com reported fourth-quarter revenue of 3.6 billion renminbi (RMB), or the equivalent of about $526 million. This was a 30.6% year-over-year increase.

The company's gross margin narrowed from 90.5% in the year-ago quarter to 87.3%. In addition, income from operations rose 15.1% year over year -- less than half the growth rate the company saw in its revenue over the same time frame.

CLSA analyst (via TheFly) Elinor Leung reduced her rating for the stock from buy to outperform, pointing to management's cautious 2019 outlook due to macro uncertainties and user acquisition spending. She expects the company's profit margin to continue narrowing in 2019.

TheFly also said the stock was downgraded to neutral from outperform by an analyst at Macquarie.

Now what

58.com guided for first-quarter revenue to rise 16% to 20% year over year -- a deceleration compared to fourth-quarter revenue growth.

While marketing and research and development costs may pressure 58.com's gross margin in the near term, CFO Hao Zhou said in the company's fourth-quarter earnings call that he believes the company's margin will improve over the long term.
