FINANCIAL OPTIONS RESEARCH CENTRE

WARWICK BUSINESS SCHOOL

UNVERSITY OF WARWICK

Director: Professor Stewart Hodges

13th ANNUAL OPTIONS CONFERENCE

Thursday & Friday 14 – 15 September 2000

The Centre was established to bridge the gap between leading academic work on financial markets and the needs of practitioners, particularly those concerned with derivative instruments and risk management. FORC's research policy is to identify and work on those topics of the greatest importance at the boundary between academic research on derivatives and its applications in the market place.

The conference provides a unique forum for leading practitioners and academics to discuss the latest advances in the pricing and hedging of derivatives. We are proud of our record of identifying and promoting key new developments:

This year’s programme provides another hand picked selection of the most exciting new theoretical and empirical research. We are pleased to present the following speakers

 

Mark Davis

10.00 On the Market Model of Futures Rates

Futures contracts are in many cases the basic securities of an interest rate market. In despite of this observation most interest rate models assume the forward rates as primary elements of the model. The process of futures prices is therefore endogenous to these models. In addition hedging strategies are formulated in terms of forward and/or spot contracts and to a less extent in terms of futures. The modelling framework used in this presentation is based on the Market Model approach. Instead of finitely compounded forward rates implied futures rates are the primary objects. The relationship between these two modelling assumptions will be discussed and first pricing results will be derived. Furthermore the relationship between a Market Model approach and the Heath, Jarrow and Morton approach for continuously compounded interest rates is investigated.

Klaus Sandmann

11.15 Libor Market Model with Semimartingales

This paper extends the Libor market model to general semimartingales. Appealing simplifications occur for special semimartingales. The case where forward Libor rates are driven by a Brownian motion and a general integer-valued random measure is especially highlighted. Basically, from the existence of a state-price density, the drift of the forward Libor system is determined in terms of the other two characteristics, namely the covariation matrix of the continuous part and Levy measure of the system. Necessary and sufficient conditions are established, and formulae for forward Libor rates and deflated bond prices are derived in the actual, forward, and spot-Libor measures. Several other topics, such as continuous compounding as the limiting case and model construction, are discussed.

2.00 Pricing Beyond the Curve

Wherever possible, practitioners seek to price derivatives in a way which is consistent with an observed yield curve. But some products extend beyond the observable yield curve. Simplistic extrapolation methods may be unstable and lead to predictable convexity losses on revaluation. This paper considers extrapolation methods which arise from Markovian models and are consistent with absence of arbitrage. We identify the long spot rate as the leading eigenvalue of an integral operator, and obtain asymptotic long bond formulas which extend the result of Dybvig, Ingersoll and Ross. We illustrate the techniques by pricing various long pension liabilities, expressed in currency terms, or relative to inflation, or defined by compounded inflation subject to caps and floors applied annually.

3.10 Optimal Hedging with Basis Risk

It often happens that options are written on underlying assets that cannot be traded directly, but where a 'closely related' asset can be traded. Rather than simply using the traded asset as a proxy for the option underlying, one should calculate some ‘best’ hedging strategy. This is an 'incomplete markets' problem, and we address it using a utility maximization approach. With exponential utility the optimal hedging strategy can be computed in reasonably explicit form using the methods of convex duality. In particular, a perturbation analysis using ideas of Malliavin calculus gives the modification to the exact replication strategy that is appropriate when the option underlying and traded assets are highly, but not perfectly, correlated.

4.50 The Sampling Properties of Volatility Cones

In this research, we extend the original work on volatility cones by Burghardt and Lane (1990) to consider of the sampling properties of the variance of variance (and the standard deviation of volatility) under a rich class of models that includes stochastic volatility and conditionally fat-tailed distributions. Because the volatility cone examines volatility at quite long horizons, the estimation requires the use of overlapping data. This theory confirms the casual observation that the estimation of the variance of variance is downward biased when estimation is done on an overlapping basis. We identify what this bias is and derive an adjustment factor that approximates an unbiased estimate of the true variance of variance over various horizons when overlapping data is used.

    1. Hedging Errors under Misspecified Asset Price Processes

The paper provides a fairly general representation for hedging errors under misspecified asset price processes. The hedging errors are then studied in more detail for standard vanilla options, including the relationship between the size of the hedging errors and the error in volatility. Two alternative approaches are provided for estimating the moments of the distribution of hedging errors: binomial tree and kernel estimation. The analysis has potential implications for understanding the risks of other, more exotic, contingent claims and of portfolios of claims.

10.35 Historical Option Pricing: Smile, Skew and Volatility Correlations

In this seminar, we will present recent advances in option pricing beyond Black-Scholes, in particular we will discuss the relationship between smile and skew/kurtosis in the terminal distribution. The main point is to understand why the smile survives to long maturity. From an empirical analysis of the statistics of stock prices, we will illustrate the impact of long-range volatility auto-correalations on kurtosis and that of price-volatility correlations on skewness. In the light of this analysis, we will comment on recent multifractal models.

12.00 The Fine Structure of Asset Returns: An Empirical Investigation

Rubinstein binomial approximation of the process as well as delivering unique pricing of derivatives by arbitrage. In order to capture the recent moves of the Dow Jones and Nasdaq, we propose to introduce jumps in the trajectories. In contrast with the Continuity of price processes has served finance as a convenient and powerful assumption, justifying the Cox-Ross-standard modelling of jumps for asset returns, the jump component can display finite or infinite variation. Empirical investigations of time series indicate that index dynamics (e.g., SPX, RUT) are essentially devoid of a diffusion component while this component may be present in the dynamics of individual stocks: we analyse over a five year period time series of 13 stock prices including IBM, General Electrics and other major companies. This result leads to the conjecture that the risk-neutral process should be free of a diffusion component for both indices and individual stocks. Empirical investigation of options data tends to confirm this conjecture.

2.30 Asymmetries in Dynamic Hedging

Discreteness in time and price movements of asset prices induces significant asymmetries between short and long option portfolios. We examine the microstructure of order execution and the tracking of the replicating process. We argue that an operator long options may incur positive transaction costs.

3.55 Model Risk in Option Pricing

Trading in derivatives involves heavy use of quantitative models for valuation and risk management. Traders use the available models extensively, and make a variety of ad hoc adjustments to try to bring the models into line with the real world. The practical result is exposure to "model risk". We will report results from an empirical simulation using historical data for several important markets, that allow a quantitative assessment impact of model risk. Pricing and hedging errors due to imperfect models and inaccurate volatility forecasts create sizable risk exposure. We then go on to consider the broader issue of how to evaluate the practical contribution of a given model. The performance of a theoretical model is compared to that of a "null model" based on minimal information.
