Value-at-risk measures apply time series analysis to historical data 0 r, –1 r, –2 r, … , –α r to construct a joint probability distribution for 1 R.They then exploit the functional relationship θ between 1 P and 1 R to convert that joint distribution into a distribution for 1 P.From that distribution for 1 P, value-at-risk is calculated, as illustrated in Exhibit 1 above. It’s essentially how much the value of the stock or bond investments goes up and down over time.
