We provide a closed-form solution to an optimal investment and consumption problem for a constant absolute risk aversion (CARA) agent, who faces execution costs when trading correlated risky assets with return predictability. The optimal investment strategy indicates that the agent should trade...

This paper studies the timing of trades under mean-reverting price dynamics subject to fixed transaction costs. We solve an optimal double stopping problem to determine the optimal times to enter and subsequently exit the market, when prices are driven by an exponential Ornstein-Uhlenbeck...

A classic result by Merton (1973) is that, except just before expiration or dividend payments, one should never exercise a call option and never convert a convertible bond. We show theoretically that this result is overturned when investors face frictions. Early option exercise can be optimal...

Stop-loss strategies are commonly used by investors to reduce their holdings in risky assets if prices or total wealth breach certain pre-specified thresholds. We derive closed-form expressions for the impact of stop-loss strategies on asset returns that are serially correlated, regime...

Small transaction costs made frequent trading become a common practice among financial institutions and retail investors. Yet, the existing models of trading in the presence of transaction costs predict that trading should be infrequent. This study considers the effects of convex transaction...

Among 37 methods to reduce transaction costs, we recursively choose the best method for next period's investment in each of three portfolio strategies: levered-momentum, zero-cost momentum, and the equally-weighted market. We identify a few of the best methods and offer a framework by which...

To examine whether corporate credit risk is cheaper to trade in the bond or credit-default swap (CDS) market, we estimate individual roundtrip transaction costs for 851 CDSs traded during 2009-2014. Effective half-spreads are 14 bps of the notional amount for dealer-to-enduser and 12 bps for...

We find robust portfolio rules for ambiguity-averse fund managers in a financial market with proportional transaction costs. The model proposed in this paper permits a liquidity premium much bigger than those found by most empirical literature. Our liquidity premium is much bigger when using...
