It progresses at a pace that is comfortable for those with less mathematical expertise yet reaches a level of analysis that will reward even the most experienced. The strong applied emphasis makes this book ideal for anyone who is seriously interested in mastering the quantitative techniques underpinning modern financial decision making. From reader reviews: Linda Christopher: Nowadays reading books be a little more than want or need but also turn into a life style. This reading behavior give you lot of advantages. The huge benefits you got of course the knowledge your information inside the book which improve your knowledge and information. The information you get based on what kind of publication you read, if you want attract knowledge just go with training books but if you want feel happy read one together with theme for entertaining such as comic or novel. Often the Quantitative Methods for Finance is kind of book which is giving the reader erratic experience. Armando McFarland: The reason? Because this Quantitative Methods for Finance is an unordinary book that the inside of the e-book waiting for you to snap it but latter it will jolt you with the secret it inside. Reading this book next to it was fantastic author who write the book in such wonderful way makes the content within easier to understand, entertaining way but still convey the meaning totally. So , it is good for you for not hesitating having this anymore or you going to regret it.

He should be an astute student of the markets, familiar with the vast array of modern financial instruments and market mechanisms, and of the econometric properties of prices and returns in these markets. If he works in the financial industry, he should also be well versed in regulations and understand how they affect his firm. That sets the academic syllabus for the profession.

Carol takes the reader step by step through all these topics, from basic definitions and principles to advanced problems and solution methods. She uses a clear language, realistic illustrations with recent market data, consistent notation throughout all chapters, and provides a huge range of worked-out exercises on Excel spreadsheets, some of which demonstrate 22 xx Foreword analytical tools only available in the best commercial software packages.

Many chapters on advanced subjects such as GARCH models, copulas, quantile regressions, portfolio theory, options and volatility surfaces are as informative as and easier to understand than entire books devoted to these subjects.

Indeed, this is the first series of books entirely dedicated to the discipline of market risk analysis written by one person, and a very good teacher at that.

A profession, however, is more than an academic discipline; it is an activity that fulfils some societal needs, that provides solutions in the face of evolving challenges, that calls for a special code of conduct; it is something one can aspire to.

Does market risk management face such challenges? Can it achieve significant economic benefits? As market economies grow, more ordinary people of all ages with different needs and risk appetites have financial assets to manage and borrowings to control.

What kind of mortgages should they take? What provisions should they make for their pensions? The range of investment products offered to them has widened far beyond the traditional cash, bond and equity classes to include actively managed funds traditional or hedge funds , private equity, real estate investment trusts, structured products and derivative products facilitating the trading of more exotic risks commodities, credit risks, volatilities and correlations, weather, carbon emissions, etc.

Managing personal finances is largely about managing market risks. How well educated are we to do that? Corporates have also become more exposed to market risks. Beyond the traditional exposure to interest rate fluctuations, most corporates are now exposed to foreign exchange risks and commodity risks because of globalization. A company may produce and sell exclusively in its domestic market and yet be exposed to currency fluctuations because of foreign competition.

Risks that can be hedged effectively by shareholders, if they wish, do not have to be hedged in-house. But hedging some risks in-house may bring benefits e. Indeed, over the last generation, there has been a marked increase in the size of market risks handled by banks in comparison to a reduction in the size of their credit risks.

Since the s, banks have provided products e. They have also built up arbitrage and proprietary trading books to profit from perceived market anomalies and take advantage of their market views. More recently, banks have started to manage credit risks actively by transferring them to the capital markets instead of warehousing them.

Bonds are replacing loans, mortgages and other loans are securitized, and many of the remaining credit risks can now be covered with credit default swaps. Thus credit risks are being converted into market risks. The rapid development of capital markets and, in particular, of derivative products bears witness to these changes.

These derivative markets are zero-sum games; they are all about market risk management hedging, arbitrage and speculation. This does not mean, however, that all market risk management problems have been resolved.

We may have developed the means and the techniques, but we do not necessarily 23 Foreword xxi understand how to address the problems. Regulators and other experts setting standards and policies are particularly concerned with several fundamental issues.

To name a few: 1. How do we decide what market risks should be assessed and over what time horizons? For example, should the loan books of banks or long-term liabilities of pension funds be marked to market, or should we not be concerned with pricing things that will not be traded in the near future?

We think there is no general answer to this question about the most appropriate description of risks. The descriptions must be adapted to specific management problems. In what contexts should market risks be assessed? Thus, what is more risky, fixed or floating rate financing? Answers to such questions are often dictated by accounting standards or other conventions that must be followed and therefore take on economic significance. But the adequacy of standards must be regularly reassessed.

To wit, the development of International Accounting Standards favouring mark-to-market and hedge accounting where possible whereby offsetting risks can be reported together.

To what extent should risk assessments be objective? Modern regulations of financial firms Basel II Amendment, have been a major driver in the development of risk assessment methods. Regulators naturally want a level playing field and objective rules. This reinforces a natural tendency to assess risks purely on the basis of statistical evidence and to neglect personal, forward-looking views.

Thus one speaks too often about risk measurements as if risks were physical objects instead of risk assessments indicating that risks are potentialities that can only be guessed by making a number of assumptions i. Regulators try to compensate for this tendency by asking risk managers to draw scenarios and to stress-test their models. There are many other fundamental issues to be debated, such as the natural tendency to focus on micro risk management because it is easy rather than to integrate all significant risks and to consider their global effect because that is more difficult.

In particular, the assessment and control of systemic risks by supervisory authorities is still in its infancy. But I would like to conclude by calling attention to a particular danger faced by a nascent market risk management profession, that of separating risks from returns and focusing on downside-risk limits. It is central to the ethics of risk managers to be independent and to act with integrity.

Thus risk managers should not be under the direct control of line managers of profit centres and they should be well remunerated independently of company results. But in some firms this is also understood as denying risk managers access to profit information. I remember a risk commission that had to approve or reject projects but, for internal political reasons, could not have any information about their expected profitability. For decades, credit officers in most banks operated under such constraints: they were supposed to accept or reject deals a priori, without knowledge of their pricing.

Times have changed. We understand now, at least in principle, that the essence of risk management is not simply to reduce or control risks but to achieve an optimal balance between risks and returns. Yet, whether for organizational reasons or out of ignorance, risk management is often confined to setting and enforcing risk limits. Most firms, especially financial firms, claim to have well-thought-out risk management policies, but few actually state trade-offs between risks and returns.

Attention to risk limits may be unwittingly reinforced by regulators. Of course it is not the role of the supervisory authorities to suggest risk return trade-offs; so supervisors impose risk limits, such as value at risk relative to capital, to ensure safety and 24 xxii Foreword fair competition in the financial industry. But a regulatory limit implies severe penalties if breached, and thus a probabilistic constraint acquires an economic value.

Banks must therefore pay attention to the uncertainty in their value-at-risk estimates. The effect would be rather perverse if banks ended up paying more attention to the probability of a probability than to their entire return distribution.

With Market Risk Analysis readers will learn to understand these long-term problems in a realistic context. Carol is an academic with a strong applied interest. She has helped to design the curriculum for the Professional Risk Managers International Association PRMIA qualifications, to set the standards for their professional qualifications, and she maintains numerous contacts with the financial industry through consulting and seminars.

In Market Risk Analysis theoretical developments may be more rigorous and reach a more advanced level than in many other books, but they always lead to practical applications with numerous examples in interactive Excel spreadsheets. In summary, if there is any good reason for not treating market risk management as a separate discipline, it is that market risk management should be the business of all decision makers involved in finance, with primary responsibilities on the shoulders of the most senior managers and board members.

However, there is so much to be learnt and so much to be further researched on this subject that it is proper for professional people to specialize in it. These four volumes will fulfil most of their needs. They only have to remember that, to be effective, they have to be good communicators and ensure that their assessments are properly integrated in their firm s decision-making process. Its development began during the s, spurred on by the first Basel Accord, between the G10 countries, which covered the regulation of banking risk.

Over the past 30 years banks have begun to understand the risks they take, and substantial progress has been made, particularly in the area of market risks. Here the availability of market data and the incentive to reduce regulatory capital charges through proper assessment of risks has provided a catalyst to the development of market risk management software. Nowadays this software is used not only by banks, but also by asset managers, hedge funds, insurance firms and corporate treasurers.

Understanding market risk is the first step towards managing market risk. Yet, despite the progress that has been made over the last 30 years, there is still a long way to go before even the major banks and other large financial institutions will really know their risks.

Quantitative Methods in Finance

At the time of writing there is a substantial barrier to progress in the profession, which is the refusal by many to acknowledge just how mathematical a subject risk management really is.

Asset management is an older discipline than financial risk management, yet it remains at a less advanced stage of quantitative development. Unfortunately the terms equity analyst, bond analyst and more generally financial analyst are something of a misnomer, since little analysis in the mathematical sense is required for these roles. I discovered this to my cost when I took a position as a bond analyst after completing a postdoctoral fellowship in algebraic number theory.

One reason for the lack of rigorous quantitative analysis amongst asset managers is that, traditionally, managers were restricted to investing in cash equities or bonds, which are relatively simple to analyse compared with swaps, options and other derivatives. Also regulators have set few barriers to entry. Almost anyone can set up an asset management company or hedge fund, irrespective of their quantitative background, and risk-based capital requirements are not imposed.

Instead the risks are borne by the investors, not the asset manager or hedge fund. The duty of the fund manager is to be able to describe the risks to their investors accurately. Fund managers have been sued for not doing this properly.

But a legal threat has less impact on good practice than the global regulatory rules that are imposed on banks, and this is why risk management in banking has developed faster than it has in asset management.

Quantitative Methods in Finance : Keith Parramore :

Still, there is a very long way to go in both professions before a firm could claim that it has achieved best practice in market risk assessment, despite the claims that are currently made.

At the time of writing there is a huge demand for properly qualified financial risk managers and asset managers, and this book represents the first step towards such qualification. With this book readers will master the basics of the mathematical subjects that lay the foundations 26 xxiv Preface for financial risk management and asset management.

Readers will fall into two categories. The first category contains those who have been working in the financial profession, during which time they will have gained some knowledge of markets and instruments. But they will not progress to risk management, except at a very superficial level, unless they understand the topics in this book. The second category contains those readers with a grounding in mathematics, such as a university degree in a quantitative discipline.

Readers will be introduced to financial concepts through mathematical applications, so they will be able to identify which parts of mathematics are relevant to solving problems in finance, as well as learning the basics of financial analysis in the mathematical sense and how to apply their skills to particular problems in financial risk management and asset management. The level should be accessible to anyone with a moderate understanding of mathematics at the high school level, and no prior knowledge of finance is necessary.
