Why Omeros Stock Is Sliding Today Even as Biotech Shares Climb

Omeros Corp shares dropped on Wednesday, falling 3.9% to $11.20 by late morning in New York, as investors marked down the Seattle biotech even while sector funds gained. The stock opened at $11.77, touched $12.02 and then slid as low as $11.17, with about 1.38 million shares changing hands. That divergence mattered. The SPDR S&P Biotech ETF, an exchange-traded fund — a basket of shares that trades like one stock — rose 1.3%, while the iShares Nasdaq Biotechnology ETF gained 0.9%. For a small-cap drug developer, falling on a firmer biotech tape tends to put the focus back on company-specific execution.
