Über dieses Buch

Designed as a self-contained text, this book covers a wide spectrum of topics on portfolio theory. It covers both the classical-mean-variance portfolio theory as well as non-mean-variance portfolio theory. The book covers topics such as optimal portfolio strategies, bond portfolio optimization and risk management of portfolios. In order to ensure that the book is self-contained and not dependent on any pre-requisites, the book includes three chapters on basics of financial markets, probability theory and asset pricing models, which have resulted in a holistic narrative of the topic. Retaining the spirit of the classical works of stalwarts like Markowitz, Black, Sharpe, etc., this book includes various other aspects of portfolio theory, such as discrete and continuous time optimal portfolios, bond portfolios and risk management.

The increase in volume and diversity of banking activities has resulted in a concurrent enhanced importance of portfolio theory, both in terms of management perspective (including risk management) and the resulting mathematical sophistication required. Most books on portfolio theory are written either from the management perspective, or are aimed at advanced graduate students and academicians. This book bridges the gap between these two levels of learning. With many useful solved examples and exercises with solutions as well as a rigorous mathematical approach of portfolio theory, the book is useful to undergraduate students of mathematical finance, business and financial management.

Chapter 1. Mechanisms of Financial Markets
Abstract
The diversity and volume of trading in financial markets have seen a dynamic and continuous evolution over the last few decades.
Siddhartha Pratim Chakrabarty, Ankur Kanaujiya
Chapter 2. Fundamentals of Probability Theory
Abstract
The study of portfolio theory involves the prediction of future events, particularly the estimation of future values of assets, which inherently is random in nature.
Siddhartha Pratim Chakrabarty, Ankur Kanaujiya
Chapter 3. Asset Pricing Models
Abstract
In Chapter 1, we dwelled upon the aspects of financial derivatives, with the asset (typically a risky security, such as stock) being the driver of the pricing of the derivatives.
Siddhartha Pratim Chakrabarty, Ankur Kanaujiya
Chapter 4. Mean-Variance Portfolio Theory
Abstract
Given the huge array of investment alternatives available in a market, such as basic securities and derivatives, the investors’ choice needs to be made simply by taking into consideration only a limited number of such alternatives, to achieve an optimal collection of such assets or the best possible portfolio.
Siddhartha Pratim Chakrabarty, Ankur Kanaujiya
Chapter 5. Utility Theory
Abstract
The history of utility functions can be traced back to Bernoulli, who sought to resolve the St. Petersburg Paradox, which can be surmised as the “winner is the one who ends with the most at death” which (as we will see later) translates to maximization of the expected utility.
Siddhartha Pratim Chakrabarty, Ankur Kanaujiya
Chapter 6. Non-Mean-Variance Portfolio Theory
Abstract
The discussion on the Markowitz theory and the CAPM was based on the mean-variance framework, wherein the assumption was that the assets follow a normal distribution or that the investors prefer the mean-variance framework.
Siddhartha Pratim Chakrabarty, Ankur Kanaujiya
Chapter 7. Optimal Portfolio Strategies
Abstract
In this chapter, we consider optimization approaches in investment decisions, both in the discrete time and the continuous time setup, making use of the Dynamic Programming Principle and the Hamilton-Jacobi-Bellman equation, respectively.
Siddhartha Pratim Chakrabarty, Ankur Kanaujiya
Chapter 8. Bond Portfolio Optimization
Abstract
The identification of bonds as a risk-free asset must be viewed in the context of the deterministic or known nature of its return, provided the ownership of the bond is held onto, until the maturity of the bond. Having said so, any decision to liquidate a bond, prior to its maturity, has a ramification on the price of the bond, as a result of the movement of interest rate, subsequent to the purchase of the bond. This, in turn, is a consequence of the volatility in the interest rate, prevailing in the market, which impacts not only the price, but also the re-investment strategies.
Siddhartha Pratim Chakrabarty, Ankur Kanaujiya
Chapter 9. Risk Management of Portfolios
Abstract
In the course of our discussion on portfolio analysis, we have primarily identified variance and semi-variance (or equivalently standard deviation and semi-deviation, respectively) as measures of risk of an asset or a portfolio.
