Sortino Ratio

Sortino Ratio

Learn how to evaluate excess return per unit of downside risk with the Sortino Ratio tool.

Risk Metrics
Risk-Adjusted Returns
Last updated: February 21, 2026

Sortino Ratio is a risk-adjusted return metric that divides excess return by downside deviation only.

Unlike Sharpe Ratio, Sortino does not penalize upside volatility. It focuses on harmful volatility below a selected minimum acceptable return (MAR).

Why This Matters

Investors typically dislike downside surprises, not upside moves. Sortino isolates downside risk and can provide a more decision-relevant quality signal.

How to Use the Tool

Use this workflow in Sortino Ratio:

1

Select Portfolio Positions

Choose or build the portfolio to analyze.

2

Choose Benchmark

Set benchmark for relative context in output plates.

3

Set MAR and Lookback

Define annualized MAR threshold and rolling window length.

4

Calculate Sortino Ratio

Run the tool to generate chart and comparative outputs.

5

Interpret with Downside Context

Review chart behavior and compare with broader risk-adjusted metrics.

Tool Settings

Benchmark

Comparison baseline for relative reading.

MAR (annualized)

Minimum acceptable return threshold used for downside deviation.

Lookback Period

Rolling-window length for Sortino and downside deviation computation.

MAR guidance:

  • 0% penalizes only negative outcomes.
  • Risk-free-like level gives conservative baseline.
  • Target return (for example, 5%) aligns with personal objectives.

Practical ranges:

  • Negative: excess return below threshold; weak signal.
  • 0 to 1: generally sub-optimal.
  • Above 1: often acceptable.
  • Above 2: often very good.
  • Above 3: uncommon and strong.

2. Portfolio Risk-Adjusted Rank

Adds relative context for metric quality.

3. Risk-Adjusted Returns Table

Cross-validates Sortino with Sharpe, Calmar, Omega, and related indicators.

Example

If two portfolios have similar Sharpe but one has fewer downside deviations below MAR, that portfolio will usually have higher Sortino Ratio and stronger downside-adjusted profile.

Best Practices

Choose MAR deliberately

MAR selection directly impacts Sortino values.

Use rolling analysis

Check persistence instead of one-point readings.

Pair with Sharpe and Omega

Compare total-risk and full-distribution perspectives.

Recalculate after strategy changes

Allocation changes can alter downside profile quickly.
