Which Hedge Funds Own Each Biotech Stock

This page ranks every biotech stock by how many of the 45 specialist hedge funds we track own it, and whether that number rose or fell since last quarter. In Q2 2026 they held 540 stocks; RVMD and COGT were the most widely held (19 funds). Figures come from SEC 13F filings: long positions at quarter end, filed up to 45 days later.

How investors use this page

1

Before a catalyst

Ahead of a PDUFA date or a data readout, see how many specialists own the stock and whether that rose or fell last quarter.

2

Crowded or overlooked

12 or more funds is a crowded trade; one or two means ask why. Thin specialist ownership is the clearest warning in our data.

3

Follow the flows

Funds Δ and Shares QoQ show where specialists are building and where they are leaving. New positions say more than dollar changes.

4

Spot distribution

Fewer funds and fewer shares while the price rose can mean specialists sold into strength. Each fund's own page shows who sold.

Questions about specialist fund ownership

Which biotech stocks do hedge funds own most?

In Q2 2026, RVMD was held by 19 of the 45 specialist funds we track, the most of any stock. The Hedge Funds column ranks every stock the same way.

Which funds are tracked?

45 biotech and healthcare specialists, such as RA Capital, Baker Bros., Perceptive, OrbiMed and Deep Track. Each has its own holdings page.

Why does a stock show fewer funds than other sites?

We count funds that own shares. Funds holding only options are shown with the Holders filter, and we track 45 specialists rather than every institution.

When is this updated?

After each quarterly 13F deadline, 45 days after quarter end. Q3 2026 filings are due Nov 16, 2026.
