Frequently asked questions about Most owned stocks in Biotechnology

  • What are the most owned Biotechnology stocks?

    The most owned biotechnology stocks here are those that appear in the largest number of tracked institutional 13F portfolios (holder count), using the latest filings in our dataset. That measures breadth of ownership across the managers we follow, not intraday trading.

  • Which stocks are most widely held by institutional investors in the Biotechnology sector?

    The table ranks by how broadly each name appears across tracked portfolios.

  • How is "most owned" calculated?

    We rank primarily by how many distinct tracked managers report a position in each ticker. The table also shows aggregate reported shares and value so you can compare scale alongside holder counts.

  • Does this include all institutional owners?

    These rankings are based on a subset of tracked institutional investors who file SEC 13F reports. While not exhaustive, the dataset includes many of the largest and most influential funds.

  • Are these trades real-time?

    No. 13F filings are reported quarterly and may be delayed by up to 45 days. The data reflects positions at the end of the reporting period, not real-time trading activity.
