The record was last updated on 15 May 2012 with a share grant in Staar Surgical Co. The clock since the last published purchase (2 December 2008) now reads 6,551 days. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. 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. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
