BELLMAN EQUATIONS FOR TERMINAL UTILITY MAXIMIZATION
WITH GENERAL BID AND ASK PRICES

Abstract: In the paper we solve a system of Bellman equations for finite horizon continuous time
terminal utility maximization problem with general cądląg bid and ask prices. We assume that
we have a restricted number of transactions at time moments we choose. The main result
of the paper says that we can find a regular version of solutions to the system of
Bellman equations, which enables us to find the form of nearly optimal strategies.
