Calculate a minimum-variance portfolio with fPortfolio
...Reproducible example:
library(fPortfolio)
# Data
data <- SMALLCAP[, 1:20]
# Constraints
box.1 <- paste0("minW[1:nAssets] = ", 0)
box.2 <- paste0("maxW[1:nAssets] = ", 0.10)
box.3 <- "maxsumW[1:nAssets] = 1"
box.4 <- "minsumW[1:nAssets] = 1"
boxConstraints <- c(box.1, box.2, box.3, box.4)
# Portfolio Specs
Spec <- portfolioSpec()
# Calculate MinVar Portfolio
minvar <- minvariancePortfolio(
data = data,
spec = Spec,
constraints = boxConstraints)
5. Thanks a lot for your help!
