Beating the market isn't evidence of insider trading. Everyone invested deeply in tech beat the market, which is what Paul Pelosi did. If he did trade with insider information, he did it in a way that was subtle enough to look sufficiently like normal trading. This is nothing like the smoking gun of a 4x spike on oil futures 1 hour before a major announcement or a hyperspecific bet on Polymarket.

But the suggestion a bunch of Lawyers are better traders than average also stretches creduility.

Somehow, Congress beating the market simply on savvy is huge ask to believe.
