Stock transactions disclosed by members of Congress under the STOCK Act.
Congressional trading data populates after the experiment begins on June 1, 2026.
Fin45 processes House and Senate financial disclosures daily.
Under the STOCK Act (2012), members of Congress must disclose securities transactions within 45 days. These disclosures include stock purchases, sales, and exchanges by the member and their spouse.
Fin45 scores congressional trades by: committee membership relevance (does the member oversee the company's industry?), timing relative to legislation, historical alpha generation by that member, and transaction size.
Research varies, but several studies (Ziobrowski et al., 2004; Eggers & Hainmueller, 2014) have found that certain members — particularly those on oversight committees — generate abnormal returns. Fin45 tracks individual member performance over time.
Members have up to 45 days to file disclosures. The actual delay averages 28 days. Fin45 processes disclosures the day they become publicly available and accounts for this lag in signal scoring.
Yes. The STOCK Act requires disclosure of transactions by spouses and dependent children. Fin45 tracks these with equal analytical weight.
