A good market risk manager should master the basics of calculus, linear algebra, probability including stochastic calculus statistics and econometrics.
quantitative methods for finance and investments
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.
Introduction to Quantitative Methods for Financial Markets
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.
Part II presents advanced topics in quantitative finance and introduces a substantive-empirical modeling approach to address the discrepancy between finance theory and market data. It describes applications to option pricing, interest rate markets, statistical trading strategies, and risk management. Nonparametric regression, advanced multivariate and time series methods in financial econometrics, and statistical models for high-frequency transactions data are also introduced in this connection.
The book has been developed as a textbook for courses on statistical modeling in quantitative finance in master's level financial mathematics or engineering and computational or mathematical finance programs.
It is also designed for self-study by quantitative analysts in the financial industry who want to learn more about the background and details of the statistical methods used by the industry.
It can also be used as a reference for graduate statistics and econometrics courses on regression, multivariate analysis, likelihood and Bayesian inference, nonparametrics, and time series, providing concrete examples and data from financial markets to illustrate the statistical methods. The mixer gave Zarb School of Business students an opportunity to meet and network with Hofstra Faculty, Hofstra Information Technology Majors, Alumni, and IT executives from corporations and professional organizations.
Merton , one of the pioneers of quantitative analysis, promoted stochastic calculus into the study of finance. Quantitative finance started in with Louis Bachelier 's doctoral thesis Theory of Speculation, which provided a model to price options under a Normal Distribution. Harry Markowitz 's doctoral thesis "Portfolio Selection" and its published version was one of the first efforts in economics journals to formally adapt mathematical concepts to finance mathematics was until then confined to mathematics, statistics or specialized economics journals.
He showed how to compute the mean return and variance for a given portfolio and argued that investors should hold only those portfolios whose variance is minimal among all portfolios with a given mean return.
In Paul Samuelson introduced stochastic calculus into the study of finance. Merton was motivated by the desire to understand how prices are set in financial markets, which is the classical economics question of "equilibrium," and in later papers he used the machinery of stochastic calculus to begin investigation of this issue. It provided a solution for a practical problem, that of finding a fair price for a European call option, i.
Such options are frequently downloadd by investors as a risk-hedging device. In , Harrison and Pliska used the general theory of continuous-time stochastic processes to put the Black—Scholes model on a solid theoretical basis, and showed how to price numerous other derivative securities.
In particular, Master's degrees in mathematical finance , financial engineering , operations research , computational statistics , machine learning , and financial analysis are becoming more popular with students and with employers. Data science and machine learning analysis and modelling methods are being increasingly employed in portfolio performance and portfolio risk modelling,   and as such data science and machine learning Master's graduates are also in demand as quantitative analysts.
