Portfolio diversification and filter rule profits

Patricia L. Chelley-Steeley, James M. Steeley

Research output: Contribution to journalArticlepeer-review


Previously, it has been shown that the profits from a simple market timing trading rule applied to a portfolio of shares can be affected by the inter-relationships between the returns of the component securities. In this short letter, the results from applying a more sophisticated 'filter' rule to the same data are reported. Unlike the simple trading rule, the filter rule does produce some evidence of economic profits.
