NormalVaRHotspots function

Hotspots for normal VaR

Estimates the VaR hotspots (or vector of incremental VaRs) for a portfolio assuming individual asset returns are normally distributed, for specified confidence level and holding period.

NormalVaRHotspots(vc.matrix, mu, positions, cl, hp)

Arguments

• vc.matrix: Variance covariance matrix for returns
• mu: Vector of expected position returns
• positions: Vector of positions
• cl: Confidence level and is scalar
• hp: Holding period and is scalar

Returns

Hotspots for normal VaR

Examples

# Hotspots for ES for randomly generated portfolio
   vc.matrix <- matrix(rnorm(16),4,4)
   mu <- rnorm(4,.08,.04)
   positions <- c(5,2,6,10)
   cl <- .95
   hp <- 280
   NormalVaRHotspots(vc.matrix, mu, positions, cl, hp)
