The record was last updated on 18 September 2026 with a share grant in Cisco Systems, Inc. Typically, a trade is published a median of 3 days after it takes place. US insiders must file a Form 4 within two business days of a trade. 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.
