Weak tier — no edge, no validation
lowWeak performance (an unknown margin) with no statistical support. This strategy is not beating buy-and-hold meaningfully and the signal is indistinguishable from noise.
What will probably happen
- The strategy is not generating meaningful alpha above buy-and-hold on this ticker. Signals are likely noise.
- Walk-forward stability is high — the edge held up across multiple rolling out-of-sample windows, reducing the chance of parameter overfitting.
- Fewer than 10 trades — a single trade's outcome can dominate the result. Don't trust aggregate statistics from this sample.
What to do

Caveats
- Cup tiers reflect val-window performance. Live forward returns may differ from backtest — even validated strategies have drawdown risk.
- Fewer than 10 trades — single-trade outcomes can dominate the result. Aggregate statistics (Sharpe, delta_return) are unreliable at this sample size.
