The simplest way to gauge the amount of risk associated with past price returns is the associated price swings or volatility. The magnitude of volatility that was generated with the price returns can be referred to as risk to return. Investors use this risk to return, in addition to comparative risk-free interest rates, to generate a risk-adjusted returns ratio, referred to as the Sharpe ratio.
Risk-adjusted returns can assist Investors in determining which stocks or sectors in the past generated the most return for the least volatility.
