Recent SEC activity

Every filing Seth Klarman has made, newest first, across all form types — not just the quarterly 13F. A 13D activist stake is public within days and a Form 4 insider trade within two business days, so this feed moves long before the next 13F does. It updates within minutes of a filing hitting SEC EDGAR.
