Rational asset pricing models should hold across assets. Nevertheless, in practice they are often developed and tested on a single asset pricing anomaly. This approach can lead to an overabundance of idiosyncratic ‘rational’ explanations. The paper demonstrates the problem by showing that crash and recession risk are idiosyncratic to a set of anomalies and consequently invalid as rational explanations. However, even with appropriate empirical testing, our ability to find a rational model is additionally hindered by the benchmark ambiguity and joint hypothesis problems. The paper discusses personal asset pricing as an alternative to equilibrium testing when investment recommendations are required.
