Compare Investments Using Sortino Ratio

Make better investing decisions when you have access to the Sortino Ratio. With Portfolio Workstation you can easily sort your watch lists by Sortino Ratio over any time window that you like. The better the Sortino Ratio score, the better the risk adjusted returns from that investment in the past. Unlike other well known risk adjusted return measures like the Sharpe Ratio, the Sortino Ratio does not punish upside volatility, so you won’t be overlooking breakout investments.

Understanding the Sortino Ratio calculation is simple. It is made up of three main parts:

  • Compounded Return: This is the linear rate of return needed to get you from the starting price on the chart to the ending price on the chart.
  • Risk Free Rate: This is what you could earn in T-Bills (or some other cash substitute) instead of making the investment under scrutiny.
  • Downside Deviation: Think of this as the volatility of adverse price movement.

These three parts fit together in this way to calculate Sortino Ratio:

Sortino Ratio = (Compounded Return – Risk Free Rate) / Downside Deviation
