>>71801509>>71802629/biz/ here. I speak some Japanese. Not 100% sure, but here's what I think what happened.
Too many people were short selling ANYCOLOR stock, so the booking form that manages them put some restrictions on on the amount of equities an entity can borrow to short sell them. Shit is not unheard of, it's to avoid panic selling. But if I'm getting this right, it means that investors in Japan are INCREDIBLY pessimist about ANYCOLOR's future performance, to the point everyone is betting on their value going down.
