The unsystematic risks are mismanagement, increasing inven­tory, wrong financial policy, defective marketing, etc. Modern portfolio theory (MPT), or mean-variance analysis, is a mathematical framework for assembling a portfolio of assets such that the expected return is maximized for a given level of risk. The portfolio return is related to risk. Modern portfolio theory is one process that can be used to construct a portfolio that maximizes the expected return for a given amount of risk. The expected return of a portfolio provides an estimate of how much return one can get from their portfolio. Risk on Portfolio: The risk of a security is measured in terms of variance or standard deviation of its returns. Risk is uncertainty of the income/capital appreciation or loss of both. This section of the test addresses the risk return analysis. The expected return from ABC can be computed as shown in column C, which is the product of columns A and B. 4.

The theory is based on the assumption that investors are risk averse. The examples are bank deposits, where the maximum return is 13%. There is also a return for selecting the proper assets and extra return for the expertise of the portfolio manager. The standard deviation of the returns can be calculated as the square root of the variance. There is also a risk free return, which is secured by any investor by keeping his funds in say bank deposits or post office deposits or certificates. We can compute the variance of the single stock using python as: Hence, the variance of return of the ABC is 6.39. The variance of the return on stock ABC can be calculated using the below equation. Total risk = Systematic risk + unsystematic risk. The total risk of two companies may be different and even lower than the risk of a group of two companies if their risks are offset by each other.
