We analyze tactical asset allocation decisions around presidential elections using traditional methodology and then in the context of an efficient frontier analysis rather than the traditional stock-only or bond-only allocations in prior literature. To our knowledge, this is the first paper in the literature that addresses asset returns around presidential elections in a mean-variance efficient frontier framework. We find that the efficient frontier is sensitive to presidential time periods, with Democrats providing the best risk-reward opportunities over the long term, while Republicans provide better opportunities over the past quarter century.
