Abstract: We design an experiment to study how investors form their forecasts and risk allocations under different market conditions. We let our subjects observe not only past realizations of a risky asset but also a signal a that, in some rounds, helps predict its future returns. Subjects correctly perceive whether returns as predictable by the signal a in 77% of the cases. When they do not perceive a as useful, their forecast is extrapolative: subjects irrationally use the most recent returns realizations to predict future i.i.d. outcomes. However, when a is perceived as useful, they switch to a fully rational forecast model. In all cases, subjects rely on their own expectations when choosing their risky investments, particularly so when they view a as useful; but the elasticity of investments to forecasts is low — a puzzle with respect to the relatively high average risk allocations.
