      We pulled House/Senate financial disclosures in the last 3 months and aggreagated. For dollar values, we took the midpoint of the value ranges in the disclosures. To estimate returns we used the TWR (time-weighted returns) formula to account for the impact of cash flows, just like how portfolio trackers calculate returns. 

      There might be errors in the data as some of the disclosure documents are literally filed by hand. Congress members have to declare their stock transactions in 45 days, though most disclose within 2 weeks per STOCK act.

    2. There have been a couple of studies on this and it turns out that they don’t tend to do much better than the market on average. That’s not to say they aren’t taking advantage of information as they certainly are but it’s not usually done through straight stock purchases and sells. They give the information to other people who then make money and give them kickbacks.

      Most of their trades are just the obvious ones anybody with money would make, especially ones with people handling it for them. This is why making laws preventing them buying stocks is ultimately not a hard liner issue high up as that’s not where the money is being made on the whole. Dark money is the issue

    3. Am I going mad here? Is there anything to stop me just copying exactly the stock market purchases and sales of these politicians and making money myself through copying them? At a smaller rate of investment, I mean.

      It’s definitely not like threatening tariffs and putting a deadline on them only to delay them could manipulate the market and create opportunities for shorting the market… /s

      It’s too bad that neither side will ever support a trading ban enough to get one enacted.
