Fisher skewness
WebI am thinking about the time-scaling of Cornish-Fisher VaR (see e.g. page 130 here for the formula).. It involves the skewness and the excess-kurtosis of returns. The formula is clear and well studied (and criticized) in various papers for a single time period (e.g. daily returns and a VaR with one-day holding period). Web1 hour ago · Buy Aggies Tickets.
