Chаpter 11c: A risk meаsure is defined аs cоherent if it satisfies fоur cоre mathematical properties. Consider the following definitions: (i) Subadditivity: it dictates that the risk measure for two merged portfolios should be no greater than the sum of their individual risk measures before merging. (ii) Translation Invariance: it dictates that if an amount of cash, $K, is added to a portfolio, its risk measure should decrease by $K. (iii) Positive Homogeneity: it dictates that changing the size of a portfolio by a factor A results in the risk measure being multiplied by 1/A. Which of the above statements is/are correct?
