Portfolio Risk-Adjusted Return Metrics
Portfolio Risk-Adjusted Return Metrics are financial tools used to evaluate how much return an investment portfolio generates relative to the amount of risk taken. Common metrics include the Sharpe Ratio, Treynor Ratio, and Sortino Ratio. These measures help investors and managers compare different portfolios or investment strategies by standardizing performance on a risk basis, ensuring that higher returns are not solely due to taking excessive risks, thus aiding more informed decision-making.

❓ Frequently Asked Questions
What does 'risk-adjusted return' mean?
It measures how much return you earn per unit of risk, allowing comparison of performance when risk differs across portfolios.
What is the Sharpe ratio and how is it calculated?
Sharpe ratio = (Portfolio return − risk-free rate) / standard deviation of returns; higher values indicate better risk-adjusted performance, using total risk.
How does the Treynor ratio differ from the Sharpe ratio?
Treynor ratio = (Portfolio return − risk-free rate) / beta; it uses only market (systematic) risk, not total risk, making it suitable for well-diversified portfolios.
What is the Sortino ratio and what does it emphasize?
Sortino ratio = (Portfolio return − risk-free rate) / downside deviation; it focuses on downside risk, ignoring upside volatility.
What is the Information ratio and when is it used?
Information ratio = (Portfolio return − benchmark return) / tracking error; it measures consistency of excess return relative to a benchmark.
