Classical portfolio theory, as it existed in about 1975, had two parts.The formula (10) implies the two fund theorem: any ecient portfolio is a linear combination of two mutual funds, f1 1, and f2 11. We are going to analyze the mean and the variance of our total position and interpret this in terms of option prices and probabilities. 4 Analysis of the Mean. Naturally we are to determine the trading strategy in a Markovian way. Classical mean-variance analysis has always handled market incompleteness transparently, and by mapping classical mean-variance analysis to payo.More generally, any mean-variance ecient yield carries pricing information. An explicit formula for y for the nite-basis case follows from (10) and 2.

If there is a riskiess asset Write down the sample variance formula. The variance of a data set tells you how spread out the data points are.Sample mean x 14. You can think of the mean as the "centre-point" of the data. If the data clusters around the mean, variance is low.
