How Setup Odds works, and its limits
- History. Every open-market purchase (Form 4 code P, $10,000 or more) in U.S. stocks since 2020, from the SEC's quarterly insider transaction data.
- Buy events. Purchases in the same stock within 14 days count as one event. Each gets four traits: how many insiders bought, whether the CEO or CFO did, the dollar size, and the stock's move over the prior 3 months.
- Results. The stock's price change over the 90 days after the last filing became public, next to the S&P 500 (SPY) over the same days.
- Matching. For a new event we find past events with the same traits. If fewer than 25 match, we drop the least important trait (size, then the prior move) until there are enough.
Limits: this is history, not a prediction. Stocks under $3 are left out, and closed-end funds don't get odds. Companies that were later delisted often have no price data and drop out, which flatters the results somewhat. Returns are price only, before costs, taxes and dividends.
