1. Introduction: Why Risk-Adjusted Returns Matter
It’s tempting to evaluate an investment strategy purely by its headline returns—the percentage gain year over year. However, not all returns are created equal. The path you take to achieve those gains often involves varying levels of risk and volatility. If two portfolios deliver the same annual return, the one with fewer drawdowns and smoother growth is the better choice.
Risk-adjusted returns matter because they factor in volatility, ensuring you’re not taking on unnecessary danger for a small bump in performance. Two of the most widely used metrics in this realm are the Sharpe Ratio and the Sortino Ratio.
2. What is the Sharpe Ratio?
The Sharpe Ratio is a risk-adjusted performance measure that tells you how much excess return you’re getting per unit of total risk (usually measured as standard deviation).
- Formula: (Rp - Rf) / σp
- Rp = Portfolio Return
- Rf = Risk-Free Rate (such as T-bills)
- σp = Standard Deviation of the Portfolio’s Returns
- Interpretation: A higher Sharpe Ratio indicates better risk-adjusted returns. For instance, a Sharpe Ratio of 1.5 means your portfolio generates 1.5 units of excess return for every unit of total risk.
- Assumption: It assumes all volatility is bad, whether it’s upside or downside.
3. What is the Sortino Ratio?
The Sortino Ratio is similar to the Sharpe Ratio but focuses only on downside risk—which many investors consider more relevant.
- Formula:
(Rp - Rf) / σd- Rp = Portfolio Return
- Rf = Risk-Free Rate
- σd = Downside Deviation (standard deviation of negative returns only)
- Interpretation: A higher Sortino Ratio indicates better risk-adjusted returns by penalizing only negative volatility.
- Why It Matters: Many argue the Sortino Ratio is more practical because investors generally don’t mind upside volatility—it’s the downside that kills wealth.
4. Sharpe vs. Sortino: Key Differences
- Sharpe penalizes both upside and downside swings equally.
- Sortino differentiates good volatility (upside) from bad volatility (downside).
Which is Better?
- Sharpe Ratio is a good starting point for broad comparisons.
- Sortino Ratio is more nuanced, especially for strategies emphasizing downside protection (like Sidepocket’s).
5. Real-World Examples & Use Cases
- Tech Startup vs. Blue Chip Stocks
- Tech companies can have higher returns but also bigger drawdowns.
- Sharpe Ratio might be moderate if overall volatility is high.
- Sortino Ratio could highlight significant downside risk when the tech sector drops.
- Hedge Fund Strategy
- Hedge funds often have complex strategies that smooth out volatility.
- A high Sharpe Ratio might indicate consistent risk management.
- A higher Sortino Ratio suggests they excel at avoiding downside specifically.
- Personal Portfolio
- If your personal investment approach is bumpy yet yields decent returns, a low Sharpe indicates you’re taking on more risk than necessary.
- A high Sortino ratio with a moderate Sharpe suggests most volatility is on the upside—which isn’t harmful to your goals.
