CEO Litinsky sold $837K worth of MP stock on June 3, while COO Rosenthal bought $543K at a lower price on June 9. A director also received a non-cash grant of 3,038 shares. The CEO's sale is a significant insider signal given his position, even though the proportional value (~0.009% of market cap) is minimal. The COO's open-market purchase provides a modest counterweight but does not neutralize the CEO's sale.
