Bought at the close on January 2, 1987, dividends put back in, no costs and no tax. Dividends are counted to the end of 2024; from 2025 on our prices are adjusted for splits only, so dividends paid since then are left out. The stock figure counts dividends; the S&P 500 index figure does not, so compare the stock with the whole-market figure. The market figure is the Fama-French US market return (Kenneth R. French data library), which runs to July 31, 2026. Our stock prices run to September 23, 2026.
