 * Stocks ranked by composite insider-sentiment score — a peer-relative 0-100 measure of how aggressively insiders are accumulating over a trailing 90-day window, from open-market Forms 4/5 buys and sells by officers and directors (a holder that is only a 10% owner is excluded). Highest score first. Rank reflects the full scored universe and does not renumber when liquidity filters are applied.
