January's GameStop frenzy, where amateur online retail traders took what they hoped would be a rollicking joyride through the world of high finance, has left regulators scratching their heads about what to do next and the retail buccaneers themselves with quite a hangover. Some of the online buccaneers have made their next move clear and filed a class-action lawsuit against seemingly everyone who's anyone in the world of retail and wholesale securities trading. The lesson to take away from the GameStop frenzy may be that structures, securities finance markets, and participants reacted to the online investors' disruptive and provocative activity as they should have. Collusion or conspiracy was not necessary to prompt the built-in guardrails and circuit-breakers to engage. They could not have been expected to react otherwise. The online buccaneers have perhaps learned that what you don't know can, indeed, hurt you. And when you live by the sword, you die by the sword.
