We examine the evidence that expected security returns can be forecast
ed by the term premium, default premium, and dividend yield, in light
of recent findings that similar security return patterns are associate
d with Federal Reserve monetary policy developments. We extend Fama an
d French's (1989) analysis by suggesting that the monetary environment
influences investors' required returns, and hence the robustness of t
he models they propose. Our findings indicate that Fama and French's r
esults vary dramatically across monetary environments; that is, the be
havior of the business-conditions proxies and their influence on expec
ted security returns is significantly affected by the monetary sector.
