What nonpublic information about a publicly traded company do you think they received?
PS: email me
There was plenty of opportunity through January and February for "prescient" trading decisions. The main decisions in question are those executed by US legislators immediately following a national security briefing. I'm not saying it's illegal, it's not; but they're assholes for selling after the briefing and still deliberately telegraphing otherwise.
Which isn’t to defend or justify insider trading by Congress. There were intelligence analysis reports floating around Washington DC in 2019, so it was a known risk. But you didn’t need to be a beltway insider to see that possibility when insuring against that risk was very cheap.
