+### Interpretation Guide
+- **Semideviation vs mean**: downside risk relative to average return (Sortino denominator).
+- **Semideviation vs 0%**: downside risk relative to capital preservation threshold.
+- **Sharpe > 1**: good risk-adjusted return; **< 0**: negative excess return.
+- **Skewness < 0**: left tail (larger losses than gains); **> 0**: right tail.
+- **Kurtosis > 0**: fat tails — more extreme moves than a normal distribution.
+- **JB p < 0.05**: returns NOT normally distributed.
+- **β > 1**: amplifies market; **β < 1**: defensive.
+- **Beta CI**: narrow CI = precisely estimated; wide CI = unreliable beta.
+- **HAC p-value**: robust to het + autocorrelation — prefer over OLS p-value if BP/LB flagged.
+- **Breusch-Pagan p < 0.05**: heteroskedastic residuals — OLS standard errors unreliable.
+- **Ljung-Box p < 0.05**: autocorrelated residuals — model missing serial structure.
+- **β shift > 0.30**: regime change detected — beta from full period may be misleading.
