Abstract

On the theoretical side: we introduced the differential geometric framework to translate any market model into a principal fibre bundle allowing to interpret arbitrage as curvature, parameterizing arbitrage opportunities with the Lie Algebra of the holonomy group. The no arbitrage condition is equivalent to a continuity equation. On the practical side: we propose a methodology to simulate the future evolution of asset values such that: - the dimension of risk factors can be reduced. - the no arbitrage condition is satisfied. - the simulated moments of asset returns match the empirical ones.
