5. Suppose we have a risky asset with random return R. We have defined R to be, S₁ - So So R = Now we introduce the log-return, which is defined as R assume that R~ N(μ, o²) where μ = 0 and o² = 0.1. = In (st). In this question, (i) Show that R = eR 1. (ii) Calculate VaR0.95 for an investment of £150. Remember that if X~ N(μ,0²) then exis lognormally distributed with parameters and o2. You may use that for a standard normal random variable -¹(0.05) = -1.6449, where & denotes the CDF.
