I remember reading they don't disclose the exact date and hour of the purchase and sale, so intra-day trading or tight timeline trades are impossible to measure, is that correct?

I asked Claude:
Does this article take into account intraday trading or trading where the purchase and the sale occurs within 45 days?
And:
"Is there a way someone could have generated a positive revenue even though they reported as negative?"
Conclusion -- their numbers could still allow someone to make positive return even though they report mostly negative alpha
Gosh I love AI for analyzing lousy reports and articles that are inaccurate.

Looks like trade reports only include the date not the time: https://www.congressstock.com/trades

If you only measure median performance as this is doing, do any group of individuals' stock trades beat the market? I'd expect most of the alpha to come not from the median transaction but from a few well timed buys or sales.
