Abstract: The finance literature is replete with studies using the market model (MM) and the quadratic market model (QMM) as the return generating model. An alternative model, using the quadratic market model framework, was adopted by Barone-Adesi (1985) to test a two factor APT model related to the Three moment CAPM. While the effect of intervaling on the standard market model has been well documented in the literature, evidence for these other models does not exist. Accordingly, this paper tests these three models on 23 Australian Industry Equity portfolios using daily, weekly and monthly return intervals, over the sample period January 1988 to October 1996. The results favour the APT model relative to the unrestricted MM and QMM models. These findings are robust to the return intervals used.
