It is easy to believe that those making the trades were acting primarily on information known widely to the public.
Washington State announced its first deaths in late February [1]
It isn't that hard to put two and two together and expect that at least a fraction of skilled medical professionals will react.
I'm a physicist and I was still able to recognize by late Feb/early March that we were headed for trouble. Similarly, just before the Federal government stepped in with stimulus in late March/early-April 2020, as a value-investor, I'd just begun to feel that the markets had fallen enough to begin buying equities again after a multi-year hiatus.
Trading on both signals (imminent pandemic, increasingly-reasonable trailing P/E ratios) will look "exquisite", but required nothing but reading the news and making sober assessments of both situations.
One may also be able to look at the same trading data and find officials who made exquisitely-terrible trades, especially after late-March 2020, where volatile markets created outsized losers and winners.
