Accurate approximations for Asian options. (English) Zbl 0952.91029

Proceedings of the 11th annual ACM-SIAM symposium on Discrete algorithms. San Francisco, CA, USA, January 9-11, 2000. Philadelphia, PA: SIAM. 891-900 (2000).
Summary: The authors present an asymptotic fully-polynomial approximation scheme for pricing Asian options on the lattice. For an option with strike price \(X\) on an \(n\)-step binomial tree, we give an \(O(kn^2)\) time algorithm with one-sided error of \(nX/k\), for any positive \(k\). our technique works for both European Asian and American Asian options and is powerful enough to extend to other path-dependent options with similar properties. They also show several heuristic optimizations to this algorithm which maintain similar guarantees and present some experimental results. This is the first algorithm for Asian options to give guaranteed error bounds in polynomial time.
