OQRO Congress Index

How this is measured

Each purchase disclosed by a member of Congress (or a spouse or dependent child, as the filing reports it) is “placed” at the first close after its filing date, which is what anyone reading the filing could have acted on. $1,000 goes into each purchase and is then held. The line is the sum of those holdings valued at each day’s close, from split-adjusted prices. The same $1,000 goes into SPY at its close of the same day. The dashed line is the total put in.

• Equal weight: Congress filings give only an official amount range, never an exact amount, so every purchase weighs the same.
• One purchase is one member, one company and one filing date; several lines of the same filing count once. Sales, exchanges and options are not part of the basket.
• Disclosure lag: members have up to 45 days to file, and the clock here starts at the filing, so this is not what any member earned.
• Survivorship and sample: only companies OQRO tracks and prices are measured, and a purchase whose price history stops before the latest close is left out (4397 in this period). The period is short, and later purchases have had less time to move.
• No trading costs, taxes or dividends beyond what the adjusted closes contain.
• Past results describe the past. This is not investment advice and says nothing about why anyone traded.

A hypothetical replay of public disclosures: $1,000 placed in each purchase at the first close after it was reported, held, with every purchase weighted equally (Congress amounts are only official ranges), next to the same stakes in the S&P 500 (SPY). It is not what any member earned: the filing comes days or weeks after the trade, only companies OQRO prices are included, and the period is short. Past results describe the past; this is not investment advice.
