Understanding Win Rate vs. Edge

Kabu Prediction publishes two key performance metrics for each stock-rule combination. Win rate measures directional accuracy (what % of the time did the price move in the predicted direction?). Edge measures excess return above a passive buy-and-hold baseline. Both must be positive for a rule to be considered statistically advantaged.

The 45-Rule Framework

Rules span five categories: Technical (18 rules: RSI, MACD, Bollinger Bands, volume patterns), Fundamental (9 rules: P/E, P/B, ROE, dividend yield), Macro (8 rules: VIX, interest rates, USD/JPY), Sentiment (5 rules: news volume, sentiment scores), and Cross-sectional (5 rules: sector relative strength). Full methodology: https://kabu.microforge.works/methodology

Backtest Conditions

All backtests apply realistic conditions: 0.1% commission (one-way), 20.315% capital gains tax, 100-share lot constraints, no overlapping positions in the same stock. This prevents the backtest inflation common in academic studies.
