About

Mirrors the disclosed stock holdings of Rep. Bob Gibbs (Republican, OH) and family. It buys on the first trading day after each report is filed, sized by the middle of the value band reported, starts from the holdings listed in the member's annual disclosure report once that report is public, and holds each position until a sale is reported. Call options count as the stock until they expire. Members often report weeks or months late, so this is what a follower could actually have done.

Backtests are hypothetical and use today's listed companies only, which flatters results. Past performance does not predict future returns. This is research, not investment advice. How we backtest
