Grade = how their written analysis reads (A best). Trader score = how their last-20 timestamped calls performed vs SPY.
Their picks, scored
Across their last 20 scored bets: 15% hit rate, -2.54% mean alpha, trader score -4.20. Their last-14d mentions, direction-adjusted, have moved -3.1% since posting (mean over 7 mentions with price data).
