Corrections like yesterday seem to come from out of the ‘blue” but usually just some small catalyst triggers it because market was so overbought that it was overdue for a pullback. Naturally, the longer, more extended a rally is, the more likely that when a pullback finally occurs, it will be sharper than if the rally had been more balanced on it’s way up. My point is the possible catalyst (reason or excuse) is the “investigation” of Robinhood. With that platform contributing largely to the FOMO, Momentum trade incorporating margin and option trading I could see that being the impetus for the techs to selloff.
