Biotech M&A Tracker
Which biotech stocks were acquisition targets — and which specialist hedge funds were already positioned before the deal?
How This Works
Every quarter, large investment managers file SEC Form 13F disclosing their holdings. We track 20 specialist biotech hedge funds and cross-reference their positions against M&A activity. When a company they held gets acquired, it shows up here.
The Funds column shows how many of our tracked funds held the target. Click any deal for the full breakdown — position sizes, entry dates, and whether the fund was still holding at announcement.
