Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 30 share grants and 4 option exercises.

The newest entry dates from 24 July 2026: a share grant, in InterDigital, Inc. The latest purchase dates back some time: it was published 1,215 days ago, on 21 June 2023. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
