Why is Pulmonx stock sliding today?
Pulmonx (LUNG) stock fell 10.1% in pre-market trading to $2.05, with no clear catalyst. The decline follows a recent rally from its 52-week low, and profit-taking is a possible reason. The company's Q2 2026 earnings showed a 5% revenue decline, and analysts remain cautious. Broader market weakness also contributed to the drop.
