The human life is full of struggles and competitions as each activity of human being is economic or non-economic. Since in economic activity there is involvement of return while in non economic activity there is no expectation of return. Risk and return are the two sides of an investment coin and these two sides always work together hence, this book is an effort to describe the concepts of risk and return and various techniques to manage them. Moreover, it covers the various models like Markowitz Efficient Frontier, Modern Portfolio Management, Sharpe's Single Index Model, Capital Asset Pricing Model and Arbitrage Pricing Model which are generally used for minimization of the risk and optimization of the return. Apart from this, it also covers the different measures for monitoring and evaluating the portfolio. Certainly, the basic terminology and definitions of investment and Portfolio Management terms are also discussed. So in today's dynamic scenario this book can be useful for Economics, Commerce and Management students, researchers and general people to learn the better investment techniques and to create the effective portfolio investment.
