If FINRA is involved it's probably why Citron Research has gone dark and Tim Sykes is boo hooing on Twitter.
Pulling a "research report" after unusually high volume is a bad look.
22.3 million shares shorted. That's easily a weeks worth of shorting on this stock. It looks really bad for Citron and Skyes. It's a poorly covered play on their part and the two of them covering tracks in panicking ways is a bread crumb trail.
