ProQR (PRQR Quick QuotePRQR - Free Report) shares ended the last trading session 7% higher at $5.83. The jump came on an impressive volume with a higher-than-average number of shares changing hands in the session. This compares to the stock's 32.6% loss over the past four weeks.

The rise is most likely attributable to positive investor expectations for topline data from the phase II/III study evaluating ProQR's lead RNA therapy candidate, sepofarsen, in patients with genetic eye disease, leber congenital amaurosis 10 (LCA10). Topline data from the study is expected in the first quarter of 2022.

This Dutch drugmaker is expected to post quarterly loss of $0.25 per share in its upcoming report, which represents a year-over-year change of +19.4%. Revenues are expected to be $1.4 million, up 337.5% from the year-ago quarter.

Earnings and revenue growth expectations certainly give a good sense of the potential strength in a stock, but empirical research shows that trends in earnings estimate revisions are strongly correlated with near-term stock price movements.

For ProQR, 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 PRQR going forward to see if this recent jump can turn into more strength down the road.
