Questions about John Larson
Where does Wolf of Washington get its data?
Wolf of Washington builds and maintains its own database of stock trades by members of Congress: more than 102,000 trades by more than 350 members of Congress, from 2012 through October 28, 2026, updated every business day.
The trades on this page come from that database, which records the official filings with the Clerk of the House. Compiled by Wolf of Washington from the official filings. We show filings through November 3, 2026.
From all those trades, experienced traders on our team pick the ones worth acting on. Of the 16,781 congressional trades reported in the past 1.5 years, we shared 221 with members since March 2025.
Each trade row in our database counts as one trade. When the same trade (same stock, type, date and amount) appears more than once in the database, we count it once. When our database holds the amount as a single number, we show the official amount class it belongs to. A trade without an amount is neither shown nor counted. We count from December 2019 and show filings through November 3, 2026.
A filing gives no exact amount, only a fixed official amount class. We show its upper bound, for example up to $5M; the real amount is below it.
