I do not need to do it. Maybe you do. The victims are the buyers in the market who may rely on social media posts by highly regarded traders to decide what to buy, and that is the implication of the post. The SEC does not like manipulation of any sort combined with transactions going the opposite direction.
Another victim would be anyone who overpaid during that day even if they were not aware, because other persons may have bought and kept the price higher than it would have been otherwise. Manipulation of the market…basically it is a financial crime someone would be alleging, and that would not be good to allege speculatively.
As for the point, you actually quite literally miss my point. My point is not that he actually committed securities fraud. My point is that allegations of such things are very serious and they have consequences. And truth is not a defense in this context because there likely is no truth to such speculation first of all, but also such a person would not be allowed to speculate to create a pretense on being served, to then investigate. You’d likely have to have known, legally, at the time it was said.
