Zai Lab Limited Unsponsored ADR (ZLAB) shares soared 9% in the last trading session to close at $33.78. The move was backed by solid volume with far more shares changing hands than in a normal session. This compares to the stock's 20.9% gain over the past four weeks.

Last month, the company announced that the FDA had granted Orphan Drug designation to its highly active first-in-class DLL3 antibody-drug conjugate, ZL-1310, for the treatment of small cell lung cancer (SCLC). The growing optimism related to the development of ZL-1310 for treating SCLC might have driven the recent share price rally.

This company is expected to post quarterly loss of $0.65 per share in its upcoming report, which represents a year-over-year change of +33.7%. Revenues are expected to be $106.89 million, up 62.4% from the year-ago quarter.

While earnings and revenue growth expectations are important in evaluating the potential strength in a stock, empirical research shows a strong correlation between trends in earnings estimate revisions and near-term stock price movements.

For Zai Lab Limited, the consensus EPS estimate for the quarter has remained unchanged over the last 30 days. And a stock's price usually doesn't keep moving higher in the absence of any trend in earnings estimate revisions. So, make sure to keep an eye on ZLAB going forward to see if this recent jump can turn into more strength down the road.
