## MAT9760 – Advanced Mathematical Methods in Finance

Du kanske gillar. Spara som favorit. Skickas inom vardagar. This book presents innovations in the mathematical foundations of financial analysis and numerical methods for finance and applications to the modeling of risk.

The topics selected include measures of risk, credit contagion, insider trading, information in finance, stochastic control and its applications to portfolio choices and liquidation, models of liquidity, pricing, and hedging. The models presented are based on the use of Brownian motion, Levy processes and jump diffusions.

Black was ineligible for the prize because of his death in The next important step was the fundamental theorem of asset pricing by Harrison and Pliska , according to which the suitably normalized current price P 0 of a security is arbitrage-free, and thus truly fair, only if there exists a stochastic process P t with constant expected value which describes its future evolution: [8]. A process satisfying 1 is called a " martingale ". A martingale does not reward risk. The relationship 1 must hold for all times t: therefore the processes used for derivatives pricing are naturally set in continuous time.

The quants who operate in the Q world of derivatives pricing are specialists with deep knowledge of the specific products they model.

Securities are priced individually, and thus the problems in the Q world are low-dimensional in nature. Calibration is one of the main challenges of the Q world: once a continuous-time parametric process has been calibrated to a set of traded securities through a relationship such as 1 , a similar relationship is used to define the price of new derivatives. Risk and portfolio management aims at modeling the statistically derived probability distribution of the market prices of all the securities at a given future investment horizon.

Based on the P distribution, the buy-side community takes decisions on which securities to purchase in order to improve the prospective profit-and-loss profile of their positions considered as a portfolio. For their pioneering work, Markowitz and Sharpe, along with Merton Miller, shared the Nobel Memorial Prize in Economic Sciences , for the first time ever awarded for a work in finance. The portfolio-selection work of Markowitz and Sharpe introduced mathematics to investment management. With time, the mathematics has become more sophisticated.

Thanks to Robert Merton and Paul Samuelson, one-period models were replaced by continuous time, Brownian-motion models , and the quadratic utility function implicit in mean—variance optimization was replaced by more general increasing, concave utility functions. Much effort has gone into the study of financial markets and how prices vary with time.

This is the basis of the so-called technical analysis method of attempting to predict future changes.

One of the tenets of "technical analysis" is that market trends give an indication of the future, at least in the short term. The claims of the technical analysts are disputed by many academics.

Over the years, increasingly sophisticated mathematical models and derivative pricing strategies have been developed, but their credibility was damaged by the financial crisis of — Contemporary practice of mathematical finance has been subjected to criticism from figures within the field notably by Paul Wilmott , and by Nassim Nicholas Taleb , in his book The Black Swan.

Wilmott and Emanuel Derman published the Financial Modelers' Manifesto in January [12] which addresses some of the most serious concerns. Bodies such as the Institute for New Economic Thinking are now attempting to develop new theories and methods. In general, modeling the changes by distributions with finite variance is, increasingly, said to be inappropriate. Large changes up or down are more likely than what one would calculate using a Gaussian distribution with an estimated standard deviation. But the problem is that it does not solve the problem as it makes parametrization much harder and risk control less reliable.
