It doesn't, however, show sales of nvidia stock prior to this release. Thus no such sales happened, unless you have any further evidence.
It is, however, looking like JH's fellow philanderer donald knew, and kept it under wraps for personal gain. Probably insider trading. I mean, just look at how much donald and his family's wealth has increased compared to the S&P500, or Warren Buffett.
Congress members are not mandated to fill a trade as it happens. If Nancy Pelosi latest filling day was Nov 6 (as you are pointing out), it means that she is only forced to show trades up to 30 days before (and that is mostly what she does as her median filling delay is of 24 days).
Also, as you are so keen to bring Trump into the discussion for some reason. I must sadly tell you that the chap is only 4.4% up compared to S&P during all his history as a member of the government/representative. The guy is not nearly the same financial genius as Nacy Pelosy.
