Robert Langer: trading record in brief
Robert Langer (board member) discloses dealings in 3 companies, chiefly Seer, Inc., Ocata Therapeutics, Inc. and Moderna, Inc. We count 9 filings; the first trade dates from 31 December 2015 and the latest from 28 July 2026.
The filings describe grants, exercises and other transfers rather than trades on the open market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
The record was last updated on 30 July 2026 with a share grant in Seer, Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
