Most recently, on 10 August 2026, the filings show an open-market sale worth €86k in InterDigital, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
