Results by strategy

0 of 10 beat buy and hold (CAGR 7.6%, drawdown -39.0%).

Sharpe leader (same as main): ROC 모멘텀 — CAGR 7.1%, MDD -42.2%, Sharpe 0.45, 100% exposure. With at least 95% exposure, it should be treated as hold-like, not strong evidence of timing skill.

No strategy retained at least 75% of buy-and-hold CAGR while reducing drawdown by both 20% relatively and 5 percentage points absolutely.

The alternative must retain 75% of buy-and-hold CAGR, improve drawdown by at least 20% and 5 percentage points, and stay below 95% exposure; the ranking weights return retention 60% and drawdown improvement 40%.
