Optimal portfolio is the one that provides the highest (excess) return per unit of risk measured by the Sharpe ratio (Estrada, 2010: 1). We show that even when the goal is to trade a single asset, its optimal execution may involve transitory trades in other assets. Using a model with time-varying expected returns and volatility, we form optimal portfo-lios sequentially and generate out-of-sample portfolio returns. Plotting the optimal portfolio as a function of the correlation, you get the following chart. Each CAL is uniquely identiﬁed by its slope. The introduction of a risk-free asset into the portfolio possibility set considerably simplifies the analysis. For small portfolios, µ → 0, optimal adaptive trade schedules coincide with the optimal static trade schedules of Almgren and Chriss [1].
