In the existing literature on barrier options, much effort has been exerted to ensureconvergence through placing the barrier in close proximity to, or directly onto, thenodes of the tree lattice. In this paper we show that this may not be necessary toachieve accurate option price...

Financial models are largely used in option pricing. These physical models capture several salient features of asset price dynamics. The pricing performance can be significantly enhanced when they are combined with nonparametric learning approaches, that empirically learn and correct pricing...

Do you enjoy chores such as mowing the lawn or, as it is called in Canada, shovelling the snow? Below we discuss a simpler method of trimming the hedge, suggested by Barone-Adesi, Engle and Mancini. Assuming the option price is homogeneous our calculation is model independent and provides delta...
