Danger of getting too nerdish. So a pause to explain the Sharpe Ratio in "lay person's" terms.
The concept is that one should expect over time to earn more on risky assets than on government bonds, for example. This excess return is known as the Equity Risk Premium. Risk is measured by the "volatility" of price movements. A typical stockmarket index would have a volatility between 15% and 20% per annum.
The Sharpe Ratio is the ratio of the Equity Risk Premium divided by the Volatility. It is an historic concept rather than a forward looking projection. It can vary significantly over time and over time periods even for the same asset class.
Gemini (a member of the AI family) suggests that a Sharpe Ratio of 1.0 is a target. Seems high to me.
Additions or corrections to that explanation most welcome.
