$Robinhood(HOOD.US)$ earnings report itself is fine, but management indicated a significant downward trend in retail trading volume. I think this is not too bad news for Robinhood itself (after all, it is not very profitable on trading volume). Instead, the impact on WSB retail stocks like $GameStop(GME.US)$ $BlackBerry(BB.US)$ may be a bit bigger.
