Rank Rank Position on the leaderboard, ordered by Sharpe ratio. #4

Returns

Annualized Return Annualized Return Average yearly return, after scaling the portfolio to the 10% volatility target. This model: Better than 97% of the 86 other models. 44.22%

Best 12M Return Best 12M Return The best compounded return over any 12 consecutive months of the test period. This model: Better than 85% of the 86 other models. 142.10% Oct 1999 – Sep 2000

Worst 12M Return Worst 12M Return The worst compounded return over any 12 consecutive months of the test period. This model: Better than 91% of the 86 other models. 0.00% Jun 2022 – May 2023

Risk

Max Drawdown Max Drawdown Largest peak-to-trough decline during the test period. This model: Better than 94% of the 86 other models. -6.82%

Downside Deviation Downside Deviation Standard deviation of negative monthly returns only. This model: Better than 99% of the 86 other models. 0.842%

Annualized Downside Dev Annualized Downside Deviation Downside deviation in annual terms. This model: Better than 99% of the 86 other models. 2.92%

Risk-Adjusted Performance

Sortino Ratio Sortino Ratio Return per unit of downside risk: like Sharpe, but only negative volatility counts. This model: Better than 99% of the 86 other models. 15.1555

Calmar Ratio Calmar Ratio Annualized return divided by the maximum drawdown. This model: Better than 95% of the 86 other models. 6.4855

Win Rate Win Rate Share of months with a positive return. This model: Better than 91% of the 86 other models. 90.7%

Distribution

Skewness Skewness Asymmetry of returns. Positive skew means more large gains than large losses. 0.349 (Near-symmetric)

Kurtosis Kurtosis Tail thickness. Higher values mean more extreme months, in either direction. 0.165 (Thin tails)

Volatility Targeting

Raw Volatility Raw Volatility Volatility of the portfolio before it was scaled to the 10% target. 823.44%

Scaling Factor Scaling Factor Multiplier applied to the portfolio to reach the 10% volatility target. 0.012

Observations Observations Number of monthly returns used for the evaluation. 408 months

Market Exposure (CAPM)

Beta Beta Sensitivity to market movements. 1.0 moves one-for-one with the market. 12.79

Alpha (ann.) Alpha (ann.) Average yearly return not explained by market exposure (the monthly regression alpha × 12). This model: Better than 95% of the 86 other models. 42.91%

Information Ratio Information Ratio Annualized alpha per unit of residual risk: alpha ÷ std(residuals) × √12. This model: Better than 97% of the 86 other models. 4.4155

R² R² Share of the return variance explained by market movements. 5.8%

Alpha t-stat Alpha t-stat Statistical significance of the alpha estimate. A |t| above about 2 suggests it is not chance. 25.43
