For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
