What is a risk?
A risk is the chance, high or low, that any hazard will actually cause somebody harm. Risk is the potential for a negative outcome. Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value, often focusing on undesirable consequences.
Risk can be measured using statistical methods that are historical predictors of investment risk and volatility. Commonly used risk management techniques include standard deviation, Sharpe ratio, and beta.
