• Downside risk is an estimate of the potential loss in value of a security if market conditions cause the price of that security to decline.

  • Risk of loss is a general term for the risk of loss in an investment, as opposed to the symmetrical probability of loss or profit.
  • Some investments have infinite downside risk, while others have limited downside risk.
  • Examples of downside risk calculations include semi-variance, value at risk (VaR) and Roy’s Safety First.
