Abstract | We consider the execution of portfolio transactions with the aim of minimizing a combination of volatility risk and transaction costs arising from permanent and temporary market impact. For a simple linear cost model, we explicitly construct the efficient frontier in the space of time-dependent liquidation strategies, which have minimum expected cost for a given level of uncertainty. This analysis yields a number we call the "half life" of a trade, the natural time for execution in the absence of exogenous time constraints. We also construct optimal strategies for trading through scheduled news events such as earnings announcements. |
