Hybrid mutual funds and market timing performance

examine the stock market timing ability of two samples of hybrid mutual funds. I find that the inclusion of bond indices and a bond timing variable in a multifactor Treynor-Mazuy model framework leads to substantially different conclusions concerning the stock market timing performance of these funds relative to the traditional Treynor-Mazuy model. Results from the multifactor Treynor-Mazuy model find less stock timing ability over the 1981-91 time period and provide evidence of significant stock timing ability across the second fund sample during the 1992-2000 time period.
