In plain language
Answers: 'For every unit of risk taken, how much extra performance did I earn compared with taking no risk?' A Sharpe above 1 is generally considered good; the higher it is, the better you were compensated for risk.
Technical definition
Ratio of the excess return over the risk-free rate to the total annualised volatility on the selected sample.
