Sortino Ratio
Definition
The Sortino Ratio measures risk-adjusted return by focusing only on downside volatility. It improves on the Sharpe Ratio by excluding positive price movements from the risk calculation. A higher Sortino Ratio means an investment is generating better returns relative to its downside risk.
Why It Matters to Investors
- Ignores upside volatility, which most investors welcome
- Focuses on losses and bad outcomes, making it more investor-relevant
- Highlights strategies that produce smoother downside behavior
- More accurate than the Sharpe Ratio for asymmetric return profiles
- Helps compare investments that look similar on paper but behave very differently in stressful markets
The TiltFolio View
The Sortino Ratio gives a more meaningful picture of risk-adjusted performance than the Sharpe Ratio, especially for strategies that trend upward with occasional setbacks. At TiltFolio, we prioritize metrics that distinguish between good and bad volatility, and the Sortino Ratio does that well.
Both TiltFolio systems show high Sortino Ratios, reflecting their ability to manage downside risk effectively. TiltFolio Adaptive's trend-following system reflects its ability to sidestep prolonged downtrends while staying exposed to rising markets. TiltFolio Balanced achieves strong Sortino ratios through its strategic diversification (50% bonds, 30% stocks, 20% gold), which provides consistent downside protection through diversification.
We believe investors should care more about avoiding losses than smoothing all volatility. The Sortino Ratio captures this logic directly. Both systems are designed to minimize downside volatility: TiltFolio Adaptive through dynamic rotation and TiltFolio Balanced through strategic diversification.
Real-World Application
• A strategy with a 10% annual return and moderate downside volatility might have a Sortino Ratio of 1.2, indicating solid performance with manageable downside risk.
• A traditional 60/40 portfolio might show a Sortino Ratio around 0.7 to 1.0, depending on the timeframe
• TiltFolio's system shows a Sortino Ratio above 1.3, which indicates strong downside protection
