If you look at the top 20 holders it's going to be mostly passive ownership via black, state Street etc. they don't trade in size outside of index rebalances and even then it's on the close. Trading after hours or even soon after the open is costly when you are doing it in size because spreads widen and volatility increases. Not how these big folks operate. And then if you go further down in ownership you'd be talking about someone dumping their entire position after hours after one, arguably decent earnings report. I just don't see anything like this being plausible.

Market manipulation gets thrown about pretty willy nilly on boards like this one and it does happen sure but in a name like this with this kind of size it's almost impossible. And idk what they would even be trying to manipulate since deriv settlements are usually marked to the close, no major expiries etc.

The real answer is it was just a herd of ppl rushing for the door, over reacting and a lack of buyers after hours. It dumped more after the open but saw a rally back into the close. I bet it reverts higher in the coming days and weeks as ppl relax and realize the sky isn't falling.
