Key Take Aways
Smoke or fire? The article doesn’t try to answer the question prematurely, it defines how the data could answer it.
The starting point is Congressional trade history combined with stock-performance data and information about members of Congress. From there, the analysis proposes several tests:
1
Do Congressional holdings outperform the broader market?
2
Which members consistently outperform or underperform?
3
Who trades immediately before major stock movements?
4
Do family members make suspicious trades?
5
Does committee assignment affect trading behavior or returns?
The value of the piece is its analytical mindset. Rather than turning an inflammatory claim into a conclusion, it asks: What would we actually expect to see in the data if the claim were true?
It is ultimately a demonstration of how analysts can take a controversial real-world question, define observable signals, and build a framework for testing it systematically.
Congressional Insider Trading
We all remember it. On a crazy day in March 2020, Tom Hanks got Covid, the NBA suspended its season, and stock markets plummeted 13%.
But not for Congress. Weeks earlier, armed with closed-door information, Senators and Representatives sold stock and avoided the steep losses that hit the rest of the American public.
Uproar ensued. Representatives have since explained that the timings were coincidental. That they were not trading on private information. And that they did nothing wrong. Yet suspicions of Congressional insider trading have continued to swirl. And not just for this incident.
Accusations of Congressional insider trading certainly sound bad. But is it smoke or fire? Being diligent analysts, we want to find out.
To start, we asked ourselves the question – What exactly would Congressional insider trading look like in the data? To help answer this, we’ve collected Congressional trade history data, stock performance data and general information about members of Congress.
Step two, we’ll want to examine Congressional behavior and stock outcomes across several dimensions. Here are a few important questions we want to ask:
- How do Congress’ stock holdings perform relative to the market at large?
- Who tends to outperform the market?
- Who tends to underperform the market?
- Who makes trades right before big stock shifts?
- Who’s family members make suspicious trades?
- Does committee assignment influence stock trades and returns?
These are just some of the important questions to answer, and we’re excited to get to the bottom of it.
