BridgeBio short interest falls 3% to 22.7M

Watch: Watch Q1 2026 Attruby revenue and regulatory updates on late-stage candidates to gauge BridgeBio's ability to scale profitably.

Short interest in BridgeBio dropped 3% to 22,676,856 shares, representing 19.5% of the float. Days to cover remain elevated at 13.8. This decrease contrasts with recent persistent insider selling and a mixed analyst consensus, with ratings from Mizuho and HC Wainwright holding at Outperform and Buy respectively.

Declining short interest amid insider selling and mixed analyst views suggests cautious positioning ahead of potential upcoming catalysts in this volatile biotech name.
