Cliff Asness announces partner Antti Ilmanen's new research series on how investors form beliefs about expected returns—a shift from prior work focused on forecasting returns themselves. Academic models and practitioner surveys often diverge sharply, particularly at valuation extremes (2000, 2021, 2024). Academics focus on required returns in present-value denominators; many practitioners emphasize numerators (cash flows), conflating high growth with high returns regardless of price. Individual investors and equity analysts extrapolate recent performance excessively, inflating valuations and locking in low future returns. Institutional and bond investors show more rational, less extrapolative behavior. Asness argues contrarian strategies outperform long-term extrapolation, making Ilmanen's analysis timely given current market "nuttiness" across valuations and geographies.
