Two figures per horizon, both hypothetical and not investment advice: Member's own — what the trade returned if you'd bought when Blumenthal did (not public yet, so not replicable); and If you'd followed — buying only after the disclosure went public, which is what a follower could actually do. The gap between them is the cost of the disclosure lag.

The count falls at longer horizons because recent trades haven't completed the full window yet — a return that hasn't happened is never estimated (no look-ahead). Only buys with usable price data are counted.

FAQ Common questions

How many stock trades has Richard Blumenthal disclosed?

30 disclosed stock transactions — 18 buys and 10 sells — all from official Senate financial disclosures.

Is this insider trading?

No. QuantCapitol surfaces the timing and context of publicly disclosed trades for transparency. A trade near related legislation is a coincidence we flag — never an accusation of wrongdoing.

Where does this data come from?

Official US House Clerk and Senate electronic financial disclosures. Every trade links back to its original filing so you can verify it yourself.

About this data. Sourced from official House Clerk and Senate eFD financial disclosures (Senate via a maintained community mirror — see project documentation). Transaction amounts are reported as ranges, not exact figures. Interest scores, consensus labels, and backtested performance are proprietary analytical calculations based on public data and are not investment advice. Backtested performance is a hypothetical simulation, not actual portfolio performance.
