PART ONE: QUESTION 1

1. INTRODUCTION What is the ultimate goal in a diversification strategy? Most investors must say “it is to Certainly, everyone knows

improve the investment performance by reducing the risk”.

risk is an essential element of strategic management and often appears as on an element of empirical studies reported in the strategic management literature. It figures prominently

in both management and many empirical studies of industry, firm and business unit performance (Bettis and Mahajan, 1990). Two measures of risk have predominated in the strategic management literature: one or both of the parameters (alpha α or beta β) derived from the Capital Asset Pricing Model (CAPM), including risk-adjusted returns from the CAPM, and variance or its derivatives, for instance, standard deviation. Thereinafter, this assignment will concentrate on categorizing risk and evaluating its relationship with betas from an asset pricing perspective.

2. RISK One way to categorize risk is to distinguish between systematic risk and unsystematic risk. Total risk is the sum of systematic (market) risk and unsystematic (non-market or specific) risk. Simply, systematic risk is non-diversifiable component of total risk and

unsystematic risk is the diversifiable component of total risk. Here below is the methods to represent total risk. Total risk = Systematic risk + Unsystematic risk = Undiversifiable risk + Diversifiable risk = Market risk + Issuer risk 2.1 Systematic and Unsystematic Risk William Sharpe (1964) and John Lintner (1965) developed the CAPM to mark the birth of asset pricing theory. The CAPM extend the model of portfolio choice developed by In the portfolio theory, Harry Markowitz (1952) introduced the
