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. “% correct” is the share of those scored calls whose direction-aware return was positive at the horizon — in a rising market a bullish call is correct by default, so read it beside the market, not alone.
Scored calls
Every tracked call with at least one matured horizon: the rows behind the Returns
