Enhancing Outcomes from Optimal Portfolio Construction
Portfolio Construction and Optimization
What constitutes an optimal portfolio? Different investment philosophies and doctrines play a part, as do the biases held by a portfolio manager and the parameters they are operating within. Together, these forces (and others) guide investment decision-makers towards a particular set of choices (and outcomes).
Some of these choices may stem from an analysis of historical correlations or particularly pervasive long-term trends. Others may be rooted in guidelines for strategic asset allocation, beliefs about factors and factor combinations, or methods for managing/mitigating equity market volatility. Optimality itself is relative, unless the relevant parameters are well-defined.
