The trade
Which stock a member of Congress reported buying or selling, and when it was disclosed.
Congressional trading tracker
See what Congress is buying. Then see if it's worth buying.
Public disclosure filings show which stocks members of Congress are trading. Market Lens puts that next to a Buffett-style quality score and a fair-value estimate — so a headline becomes a decision you can actually reason about.
The business
A 0–100 Buffett-style checklist score: is this a durable, understandable, financially strong company?
The price
A DCF fair-value estimate so you can see whether the stock is a bargain, fair, or stretched today.
A politician's trade gets your attention. The fundamentals tell you whether to care.
Understand the method
A trade is a headline. Here is how Market Lens turns it into a judgement about the business behind it.

A caveat on “what happened after” a trade
Any figure showing how a stock performed after a member of Congress reported a trade — or after a bill became law — is a descriptive statistic. It describes what the price did; it does not show that the trade or the law caused the return. Markets move for countless reasons at once, and a measured return is not evidence of cause and effect.
These numbers are also sensitive to choices that are easy to overlook: the exact start and end dates, which tickers are grouped into a basket, trades with missing or late disclosure data, whether dividends are included, and which benchmark the return is compared against. Change any one of those and the figure can change materially. Treat these statistics as a starting point for your own research, not a verdict.
Frequently asked questions
Where does the congressional trading data come from?+
From public financial-disclosure filings that members of Congress are legally required to submit. Market Lens surfaces the reported trades and lets you analyze the companies involved.
Is following congressional trades a good strategy?+
It is a signal, not a strategy. A politician buying a stock tells you nothing about whether the underlying business is strong or fairly priced. That is exactly why Market Lens pairs the trade data with quality scoring and fair-value analysis — so you can judge the business, not just the headline.
Does the tracker cost anything?+
No. Viewing congressional trades and analyzing the companies is free, with no account required.
Do returns after a trade or law show the event caused those returns?+
No. Any “return after” figure is a descriptive statistic — it describes what the price did, not that the trade or the law caused it. The numbers are also affected by the dates chosen, which tickers are in the basket, missing or late disclosure data, whether dividends are counted, and the benchmark used. Treat them as a research starting point, not proof of cause and effect.
Is this investment advice?+
No. Market Lens is educational research. It shows you what was traded and how the business scores; it does not tell you what to buy or sell, and it is not investment advice.
