Raw direction-aware returns on public statements — long calls credited when the price rose, shorts when it fell, shorts capped at −100% — in a rising market this mostly measures who was long, not who has skill. Returns run from the stance date; calls are rarely closed publicly, so fixed 90-day / 180-day / 1-year horizons are used. A horizon shows only once it has fully matured, and only at 5+ scored stances.
