Admissible Trading Strategies under Transaction Costs
A well known result in stochastic analysis reads as follows: for an R-valued super-martingale X = (Xt)0≤t≤T such that the terminal value XT is non-negative, we have that the entire process X is nonnegative. An analogous result holds true in the no arbitrage theory of mathematical finance: under the assumption of no arbitrage, a portfolio process x + (H · S) verifying x + (H · S)T ≥ 0 also satis...
متن کاملFutures trading with transaction costs
A model for optimal consumption and investment is posed whose solution is provided by the classical Merton analysis when there is zero transaction cost. A probabilistic argument is developed to identify the loss in value when a proportional transaction cost is introduced. There are two sources of this loss. The first is a loss due to “displacement” that arises because one cannot maintain the op...
متن کاملTrading Regions Under Proportional Transaction Costs
In the Black-Scholes model optimal trading for maximizing expected power utility under proportional transaction costs can be described by three intervals B, NT , S: If the proportion of wealth invested in the stocks lies in B, NT , S, then buying, not trading and selling, respectively, are optimal. For a finite time horizon, the boundaries of these trading regions depend on time and on the term...
متن کاملBalancing Small Transaction Costs with Loss of Optimal Allocation in Dynamic Stock Trading Strategies
We discuss optimal trading strategies for general utility functions in portfolios of cash and stocks subject to small proportional transaction costs. We present a new interpretation of scalings found by Soner, Shreve, and others. To leading order in the small transaction cost parameter, the free boundary problem for the expected utility’s value function is shown to be dual, in the sense of Lagr...
متن کاملUtility Maximization Trading Two Futures with Transaction Costs
An agent invests in two types of futures contracts, whose prices are possibly correlated arithmetic Brownian motions, and invests in a money market account with a constant interest rate. The agent pays a transaction cost for trading in futures proportional to the size of the trade. She also receives utility from consumption. The agent maximizes expected infinite-horizon discounted utility from ...
