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?

If I remember right you can also disclose days, weeks or months after the actual transaction took place and just pay some miniscule fine as a slap on the wrists.

You remember wrong, sort of - the law requires the paperwork to be filed within 45 days, so there's no real-time disclosure requirement at all. The fine is very small, though, starting at $200 per violation.

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

Okay, so the above criticism really only applies to day trading or buying the day of news. I’m guessing that’s very uncommon. If I were a congressman with information I wouldn’t wait until the day of to buy.

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.

Sure, as long as you actually follow through and go to primary sources and do that analysis, I see no problem with using Claude as a starting point. However, please actually go to the sources it gave you and do the analysis yourself. This is way too important for someone to be able to handwave us and say we are wrong.

Tl;Dr please double check with the sources that Claude gave you?

I'm downloading the data as we speak :)

So it seems of the intra-day trades, 10% of the trades occurred on companies that gained 5% in value that same day? Not sure about this, uploading the data to a Google spreadsheet for everyone who wants to analyze this.

ASCII Table below:

+-------------------------------------+---------+----------+----------+-----------+ | Days compared | Count | Close-to | Close-to | Intraday | | | | close | close | high-low | | | | >= 5% | >= 3% | range >=5%| +-------------------------------------+---------+----------+----------+-----------+ | Same-day buy+sell (loose) | 420 | 6.7% | 14.5% | 10.7% | | Same-day buy+sell (strict) | 245 | 5.7% | 13.1% | 8.2% | | Members' other trades, same stocks | 10,957 | 5.2% | 14.5% | 9.0% | | Every trading day, same stocks | 415,259 | 3.4% | 10.7% | 6.8% | +-------------------------------------+---------+----------+----------+-----------+

About 25% of all trades are within the time frame required to report, so its impossible to tell if there was a gain or loss on those trades

For example Judy Chu seems to have 51% of trades intra day. 571 total trades, 291 were intra day.

The article literally says as much, you do have to read it tho. Taking claudeslop as gospel is gonna make you some mistakes.

▲somid3 2 hours ago | parent [-]

I used it as high-level analysis, I'm downloading the data to do my own analysis. Seems 12% of trades are intra-day... but that's the early data I'm seeing
