We examine times series momentum and covered call strategies through conventional representations across 10 asset classes. The performance of the two strategies generally outperform static buy and hold investments and they are classified as positive and negative autocorrelation factors. The tactical overlay of time series momentum and covered call strategies onto asset classes are considered beta transformations (of previous alpha). The two “beta” replacements of the underlying asset are incorporated into well established risk based allocation heuristics such as maximum diversification and equal risk contribution. The resulting portfolios show enhanced risk adjusted performance compared to the corresponding buy and hold investments. We designate this global tactical asset allocation framework as autocorrelation factor allocation, ACFA.
