Sharpe Ratio
Definition
The Sharpe Ratio measures how much excess return an investment generates for each unit of risk taken. It is calculated by subtracting the risk-free rate from the portfolio's return, then dividing by the portfolio's volatility. A higher Sharpe Ratio indicates better risk-adjusted performance.
Why It Matters to Investors
- Helps compare investments on a risk-adjusted basis
- Useful for evaluating managers and strategies
- Penalizes volatility, even when returns are high
- Encourages stable compounding instead of erratic gains
- Acts as a common benchmark across the investing world
The TiltFolio View
The Sharpe Ratio is a useful but blunt tool. It assumes all volatility is bad, even though investors generally care more about downside risk than upside gains. This limits its precision in real-world decision making.
Still, the ratio remains one of the clearest ways to measure how efficiently a portfolio converts risk into return. At TiltFolio, we track Sharpe across different market conditions for both systems, but we also lean on complementary metrics like the Sortino and Calmar ratios that focus more directly on downside risk.
Both TiltFolio systems consistently show Sharpe Ratios well above traditional benchmarks. TiltFolio Adaptive's trend-following system reflects its ability to deliver consistent returns while keeping volatility and drawdowns under control through dynamic rotation. TiltFolio Balanced achieves strong Sharpe ratios through its strategic diversification (50% bonds, 30% stocks, 20% gold), which provides consistent risk-adjusted returns across different market conditions.
Real-World Application
• A portfolio returning 12% with 10% volatility has a Sharpe Ratio of 1.0 if the risk-free rate is 2%
• The S&P 500 has historically delivered a Sharpe Ratio around 0.6 to 0.7
• TiltFolio's backtests show a Sharpe Ratio above 1.0, which reflects strong, consistent risk-adjusted performance. For simplicity, we calculate all Sharpe Ratios, including those for TiltFolio, the S&P 500, and the Diversified Portfolio, using a 0% risk-free rate.
