Sortino Ratio is a ratio that measures the risk-adjusted return or the performance of the investment with respect to the downward deviation. It is a variation of the Sharpe Ratio which differentiates downside volatility from the total volatility (upside + downside) by using the asset’s standard deviation of negative portfolio returns. The Sortino ratio is calculated by taking an investment or portfolio’s return and subtracting the risk-free rate and then dividing that amount by the asset’s downside deviation. For an investor, the downward volatility is a major concern. So this ratio gives a better picture of the downside risk associated with the fund.

**Sortino Ratio Formula**

Sortino Ratio is calculated by:

Sortino ratio = (R) – Rf /SD

where,

(R): Expected return

Rf: Risk-free rate of return

SD: Standard Deviation of the negative Asset Return.

Let’s understand it with the help of an example.

Fund A | Fund B | |

Annualized Return | 14% | 10% |

Risk free rate of return | 4% | 4% |

Standard deviation of the negative asset return | 6% | 4% |

Sortino Ratio | 1.67 | 1.5 |

Consider Fund A has an annualized return of 14% and a downside deviation of 6%. Similarly, Fund B has an annualized return of 10% and a downside deviation of 4%. The risk-free rate is 4 percent. The Sortino ratios for both funds would be calculated as:

Mutual Fund A Sortino = (14% – 4%) / 6% = 1.67.

Mutual Fund B Sortino = (10% – 4%) / 4% = 1.5.

**Pros and Cons to the Sortino Ratio**

The Sortino ratio can be a better choice by properly rewarding portfolios that have a positive skew in their performance distributions.

**Example: Calculation of the Sortino Ratio**

Let’s say we have the following set of annual returns:

15%, 6%, 11%, -7%, 10%, -3%, 9%, -7%, 16%, and 20%

**Step 1**

Average Annual Return = 70%/10 =7%

The average annual return is the sum of these (which is 70%) divided by the number of returns (ten), which is 7%.

Let’s say the target return is the expected annualized returns of the Nifty 500, or about 6%.

Therefore, the excess return is 1% (7% – 6%).

**Step 2**

Next we calculate the downside deviation. We take into account the negative values, which are -7%, -3%, and -7%.

Step 3

We square these values:

-7%^2 = 0.0049

-3%^2 = 0.0009

-7%^2 = 0.0049

The average of these downside deviations is the sum divided by the number of returns (ten):

0.0049 + 0.0009 + 0.0049 = 0.0107

0.0107 / 10 = 0.00107 = 0.107%

**Step 4**

Next we calculate the target downside deviation. This is the square root of the answer from step 3:

√.0107 = 0.0327

**Step 5**

Finally, calculating the Sortino ratio, which is done by taking the excess return from step one and dividing by the target downside deviation from step four.

0.01 / 0.0327 = 0.305

Most of the asset classes give Sortino ratios of between 0.2 to 0.3 over the long-run.

A higher Sortino ratio in mutual funds is considered to be better. So from the given result, the Sortino ratio indicates that it is generating more return per unit of the given risk and has a greater chance of avoiding large losses.
