MassMutual ‘rogue’ $lap

A MassMutual investment subsidiary has agreed to pay $4.75 million to resolve allegations by Massachusetts securities regulators including that it failed to supervise its agents, among them “Roaring Kitty,” whose posts helped spark January’s trading frenzy in GameStop shares.

The state said MML Investors Services failed to detect the activities of Keith Gill, who touted GameStop stock on his own time.
