Unit 4: Risk and Return Analysis




              Every investment involves uncertainties that make future investment returns risk-prone.  Notes
              Uncertainties could be due to the political, economic and industry factors.
              Systematic risk is for the market as a whole, while unsystematic risk is specific to an
               industry or the company individually.

              Beta is a measure of the systematic risk of a security that cannot be avoided through
               diversification.
              Beta is a relative measure of risk - the risk of an individual stock relative to the market
               portfolio of all stocks.
              If the security's returns move more (less) than the market's returns as the latter changes,
               the security's returns have more (less) volatility (fluctuations in price) than those of the
               market.
              It is important to note that beta measures a security's volatility, or fluctuations in price,
               relative to a benchmark, the market portfolio of all stocks.

              The risk/return trade-off could easily be called the "ability-to-sleep-at-night test."
              The investor can minimise his risk on the portfolio.
              Risk  avoidance  and  risk  minimisation  are  the  important  objectives  of  portfolio
               management.

              A portfolio contains different securities; by combining  their weighted  returns we can
               obtain the expected return of the portfolio.

          4.10 Keywords

          Beta Coefficient: It is a relative measure of the sensitivity of an assets return to changes in the
          return on the market portfolio.
          Beta: It is a  measure of the systematic  risk of a  security that cannot  be avoided  through
          diversification.

          Correlation: It is a statistical measure that indicates the relationship between series of number
          representing anything from cash flows to test data.
          Covariance: It is the measure of their co-movement, expressing the degree to which the securities
          vary together.
          Non-systematic Risk: The variability in a security is total returns not related to overall market
          variability.
          Portfolio: It is a collection of securities.
          Risk: Probability that the expected return from the security will not materialize.
          Systematic Risk: Variability in a security is total returns that are directly associated with overall
          movements in the general market or economy is called systematic risk.
