Think a 10% return equals success? Think again.
That return might be masking substantial risk.
Traditional measurement tools like the Sharpe ratio view all risk events identically, whether they involve price drops or surges. The complete situation is not revealed through this assessment.
The key lies in understanding how much risk accompanies your potential returns. That’s where the Sortino ratio comes in.
You have two investments. Both promise high returns, but one could be causing you significant loss risk, hidden beneath the shiny returns. Wouldn’t you want to know which one?
The Sortino ratio helps you see that risk, focusing only on the downside that truly matters to you as a risk-conscious investor.
The following discussion will explain how this remarkable metric operates as the main selection for investors who want to defend their capital against financial losses.
What Is the Sortino Ratio?
Investors use the Sortino ratio to evaluate investment results by measuring the risk potential of negative returns. The Sortino ratio determines an investment's performance regarding downside risks and investor fears of negative returns.
Downside volatility remains the sole focus of the Sortino ratio while the Sharpe ratio includes complete volatility ranges. This makes it a particularly useful tool for those more concerned about avoiding losses rather than embracing the risk that comes with high upside potential.
Here’s how it works:
If an investment’s Sortino ratio is high, it has offered strong returns relative to its downside risk.
A low Sortino ratio indicates that the investment has not provided a high return given the amount of downside risk taken.
So, what’s a good Sortino ratio to aim for? Simply put, a higher Sortino ratio means the investment has offered strong returns relative to its downside risk. The Sortino ratio allows you to evaluate whether the returns are worth the risk of potential losses—especially when you’re trying to protect your capital.
What the Sortino Ratio Can Tell You
What is the Sortino ratio telling you about your investments? Here’s how it can help:
- The Sortino ratio allows you to assess if your investment drawbacks are balanced by adequate compensation.
- A higher Sortino ratio indicates better risk-adjusted returns, as it reflects greater returns relative to risk. Standard benchmarks define a Sortino ratio above 1 as acceptable, while a value of 2 signifies excellent performance. A ratio of 3 or higher is considered exceptional.
The Sortino ratio stands above alternative ratios in terms of accuracy since it contrasts from the Sharpe ratio due to its inability to distinguish different volatility types. People guarding their investment capital should rely on the Sortino ratio since it delivers an improved assessment of targeted financial risks.
How To Calculate the Sortino Coefficient

Obtaining Sortino ratio outcomes presents no major difficulties to its computation method. The evaluation method determines the returns' excess value compared to the benchmark risk-free rate by dividing this value with the negative risk deviation.
Sortino Ratio Formula
The Sortino ratio formula is:
Sortino Ratio = (Return - Minimum Acceptable Return) / Downside Deviation
Where:
- Return is the actual return of the investment.
- Minimum Acceptable Return (MAR) is typically the risk-free rate or a threshold rate that reflects the minimum return you’re aiming for (e.g., the return on government bonds).
- Downside Deviation measures the standard deviation of negative returns, representing how much of the negative performance deviates from the expected return.
Using this formula, you can determine whether the investment is performing well compared to the risk of downside fluctuations.
Sortino Ratio Calculation Example
Let’s go through a real-world example to see how the Sortino ratio calculation works:
- Investment Return: 14%
- Minimum Acceptable Return (MAR): 5% (this is often the return on safe assets like government bonds)
- Downside Deviation: 6%
Plugging these numbers into the formula:
Sortino Ratio = (14% - 5%) / 6% = 9% / 6% = 1.5
According to the Sortino ratio calculation, this example demonstrates that the Return per risk unit reaches 1.5 points for each downside risk unit.
Expanded Example with Real-World Data
Let’s expand this example to a more realistic scenario. Imagine you’re comparing two investments:
Investment A
- Return: 12%
- Minimum Acceptable Return (MAR): 5%
- Downside Deviation: 8%
Sortino Ratio = (12% - 5%) / 8% = 7% / 8% = 0.875
The low ratio of Investment A suggests its return does not effectively offset its downside risk.
Investment B
- Return: 15%
- Minimum Acceptable Return (MAR): 5%
- Downside Deviation: 4%
Sortino Ratio = (15% - 5%) / 4% = 10% / 4% = 2.5
The Sortino ratio of Investment B demonstrates superior return capabilities compared to the downside risk.
Because Investment B reduces downside risk despite its lower 12% return, Investment B proves superior over Investment A when considering the Sortino ratio.
Difference between Sortino Ratio and Sharpe Ratio
Risk-adjusted investment evaluation methods compare the Sortino ratio and Sharpe ratio, although they handle risk measurement through separate methods.
Definition
- Sortino Ratio: Measures the return relative to downside risk, ignoring the upside volatility (positive fluctuations).
- Sharpe Ratio: Measures the return relative to total volatility, considering both the upside and downside fluctuations.
Calculation
- Sortino Ratio: The denominator is downside deviation, which only considers negative returns.
- Sharpe Ratio: The denominator is standard deviation, which measures overall volatility, both good and bad.
Sensitive
Investors focused on preserving their capital from major losses should use the Sortino ratio because it detects changes in downside risk effectively.
The Sharpe ratio serves a purpose, yet it fails to distinguish between positive volatility returns and negative volatility losses.
Sortino Ratio vs Sharpe Ratio
| Metric | Sortino Ratio | Sharpe Ratio |
|---|---|---|
| Focus | Downside risk | Total volatility (both upside and downside) |
| Formula | Excess return / Downside deviation | Excess return / Standard deviation |
| Ideal Outcome | Higher is better (more return for less risk) | Higher is better (more return for less total risk) |
| Use Case | Investors who focus on minimizing losses | Investors who care about overall risk |
The assessment of investments requires detailed knowledge of adjusted return levels because this helps investors make optimal decisions. Investors use both the Sortino ratio and Sharpe ratio to examine investment performance, yet they examine different risk dimensions because they suit different investor profiles.
Understanding the Core Differences
Risk evaluation distinguishes Sortino ratio vs Sharpe ratio through their different calculation methods.
The Sharpe Ratio calculates the investment return through total volatility analysis by integrating up and down variations in movement. The standard deviation of returns determines the Sharpe ratio calculation, thereby making all returns, including negative ones, modify the outcome.
The ratio provides complete investment performance results by measuring upward and downward volatility movements.
The Sortino ratio provides investors with value by measuring downside deviation as a main variable that exclusively considers negative volatility compared to the Sharpe ratio. Risk-averse investors find the Sortino ratio highly effective for understanding investment performances that prioritize loss reduction above gain potential. The Sortino ratio gives investors an unambiguous view of how effectively their assets manage downscale volatility risks through its penalty-based formula.
Why the Focus on Downside Risk?
The Sortino ratio evaluates only downside risk because volatility generates different effects based on its direction. Positive price changes known as upside volatility provide benefits to investors because they yield higher return numbers. Investments evaluated by the Sharpe ratio receive identical risk treatment because it includes both positive and negative volatility, which may misrepresent the investment risk characteristics.
As a result, an investment showing strong upward price trends will receive a higher risk assessment through the Sharpe ratio despite its large market fluctuations. Some investors may be unbothered by this aspect, yet investors wanting to reduce harmful risks should find the Sortino ratio more valuable than the Sharpe ratio.
Calculating the Ratios: What They Reveal
The following section will explain the calculation methods and interpretive approaches of these ratios one by one.
The Sharpe Ratio uses the excess return above the risk-free rate divided by the total return standard deviation to determine its measure. The formula is:
Sharpe Ratio = (Return of the Portfolio - Risk-Free Rate) / Standard Deviation of Portfolio Returns
The Sharpe ratio evaluates how well the investment provides suitable returns while handling its total risk without making distinctions regarding volatility types. The Sharpe ratio provides an indication of superior risk-adjusted return but neglects to show what specific risks exist in a portfolio.
Using Sortino ratio means you divide the excess return by downside deviation, which focuses exclusively on negative volatility measurements. The formula for the Sortino ratio is:
Sortino Ratio = (Return of the Portfolio - Target Return or Minimum Acceptable Return) / Downside Deviation
The Sortino ratio exclusively looks at how much return is earned for each unit of downside risk. By focusing only on the negative volatility, it provides a better understanding of how much the investment is paying off relative to the risk of loss.
Which Metric is Better for You?

Your investment targets together with risk comfort determine whether you should use Sortino ratio or Sharpe ratio:
People who want dependable investment growth coupled with loss-avoidance should consider the Sortino ratio because it addresses risk elements from a negative perspective. The Sortino ratio provides a better perspective to risk-averse investors because it reveals how much an investment succeeds when considering downside risks.
Of the two models, you must choose Sharpe ratio vs Sortino ratio based on your tolerance for investment market fluctuations. By considering upside and downside volatility, the Sharpe ratio helps investors understand investments from a broader perspective when the investor accepts both positive and negative volatility.
Final Thoughts
Investors must understand that while earning more money matters, the more significant risk should not be ignored since it determines the cost of gains. The Sortino ratio lets you perceive the hidden investment risk to identify potential exposure points quickly.
You need to reevaluate your investment metrics since traditional metrics such as the Sharpe ratio no longer provide sufficient information. The Sortino ratio offers an improved risk evaluation by assessing solely the losses that must be prevented.
