Volatility Term Structure and the Cross-Section of Option Returns: The slope of the volatility term structure strongly predicts the cross section of future option returns. Option portfolios with high slopes of the volatility term structure outperform option portfolios with low slopes of the volatility term structure by an economically and statistically significant amount.

Canonical distribution, implied binomial tree, and the pricing of American options: A new approach to pricing American options is proposed and termed the canonical implied binomial (CIB) tree method. Applied to a set of over 15,000 American-style S&P 100 Index puts, CIB outperformed BS with historic volatility in pricing out-of-the-money options; in addition, it outperformed the canonical least-squares Monte Carlo (Liu, 2010) in the dynamic hedging of in-the-money options.

We know least-squares Monte Carlo simulation to price an American option is time consuming because it involves optimal exercise decision on every step of a large number of simulation (in the least square case, to run a polynomial regression on cash flows and decide whether it is optimal to exercise or not). I once shared a simple Matlab file to illustrate the least squares Monte Carlo simulation. The situation becomes worse if we allow the presence of stochastic volatility and interest rate, typically my codes run quite a few minutes for 50,000 number of simulations.

In the paper "Fast Monte Carlo Valuation of American Options under Stochastic Volatility and Interest Rates" by Y. Hilpisch, the author demonstrates with Python script that the Least-Squares Monte Carlo (LSM) algorithm with control variates takes only less than one second to achieve satisfying accurateness. The overall statistics taken from the paper are as follows, AMAZING!

Does anyone attending the 24th Australasian Finance & Banking Conference (AFBC) happen to read this post? if yes and you are interested in having a beer, please contact me via [email protected] I am going to present a paper co-authored by my supervisor - Prof. David Newton. The conference will be on Wednesday 14 December - Friday 16 December, 2011 and an accompanying PhD Forum will be on Tuesday 13 December, 2011, in Sydney, Australia.

Quotation
The Australasian Finance and Banking Conference, organised by the Institute of Global Finance and School of Banking & Finance at the Australian School of Business at UNSW, will converge in Sydney in December 2011. This conference provides international academics and industry with the opportunity to meet and share their research and interest in finance related fields. The conference would like to invite all academics and practitioners to participate. The conference is the most prestigious finance conference in the Asia-Pacific region, and brings together the world's foremost leaders of thought from the financial community.
