The strongest recent filing
Schlosser Mario (Director) sold 600,000 shares of Oscar Health, Inc. on Aug 27, 2026, a filing that scored 86 (Strong).

Cluster activity
A cluster buy is present: 5 insiders (Baltrus Victoria, Liang Janet, Blackley Richard Scott, McAnaney Adam) traded OSCR the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
