Risk is the combination of the VaR with the % hold in the portfolio.
The calculation represents the potential loss in value of an asset or portfolio over a defined period. For example, an investment of 25% in the portfolio with a VaR of 10% could impact the total assets by 2.5% over a medium term period (1 month).
The figure is calculated with a confidence of 95% meaning that there is only a 5% chance that the value of the asset will drop more than 10%.
