Understanding Momentum Quality Score
When evaluating stocks, one of the most important questions is: "How much return am I getting for the risk I'm taking?"
The Momentum Quality Score answers this by measuring reward per unit of recent downside risk, helping you find stocks with strong performance and controlled pullbacks.
What is the Calmar Ratio?
The technical name for this is the Calmar Ratio, which measures return divided by maximum drawdown.
Drawdown refers to the fall in percentage terms from the highest price during a period.
We are calling it Momentum Quality Score (MQS). The Momentum Score tells you how fast a stock is rising. The Momentum Quality Score tells you how it got there. A high MQS means a smooth, steady climb, while a low score indicates a wild, gut-wrenching ride.

Understanding Each Column
Returns (%)
Price change from the first close in the window to the latest close
((latest_close − first_close) / first_close) × 100Max Drawdown (%)
Biggest peak-to-trough drop that occurred anywhere inside the window
((peak_high − trough_low) / peak_high) × 100Current Drawdown (%)
How far today's close is below the window's peak
((peak_high − latest_close) / peak_high) × 100MQS
Also known as the Calmar Ratio. Measures reward per unit of recent downside risk. Higher values indicate smoother, steadier climbs.
Returns ÷ Max DrawdownNote: If Max Drawdown is 0 (no pullback occurred), the MQS is undefined and displays as "—"

How to Use This Tool Effectively
Choose Your Time Frame
Select a period that matches your trading style. Short-term traders might focus on 1-4 week windows, while position traders prefer 13-52 weeks.
Sort by Your Priority
Sort by Returns to find recent strength, or by MQS to find strength with smaller pullbacks.
Combine Filters
Filter for positive Returns, then sort by lowest Current Drawdown to find strong stocks near support.
Compare Periods
Check multiple time frames to confirm trends. A stock strong across 4w, 13w, and 26w shows consistent momentum.
💡 Pro Tips
For Swing Trading: Focus on 2-4 week windows with MQS > 2.0
Finding Dips: Look for positive Returns with Current Drawdown > 5% for pullback opportunities
Risk Management: Prefer stocks where Max Drawdown < 10% in your chosen period
Industry Scanning: Compare MQSs within sectors to find relative leaders
Behind the Scenes
- • We use adjusted prices (adjusted high/low/close) to account for splits and dividends
- • Windows are rolling over calendar days (weeks × 7), using trading days within that span
- • All values are rounded to two decimals for clarity
- • Data gaps (holidays/missing bars) simply reduce observations within a window
Key Takeaways
- ✓ The MQS measures reward per unit of recent downside risk
- ✓ Higher MQSs indicate better risk-adjusted performance
- ✓ Current Drawdown helps identify pullback opportunities in strong trends
- ✓ Combine multiple time frames for comprehensive momentum analysis
