1 Is Economic Uncertainty Priced in the Cross-Section of Stock Returns? Turan Bali, Georgetown University Stephen Brown, NYU Stern, University Yi Tang, Fordham University 2018 CARE Conference, Washington DC May 18-19, 2018

2 Introduction Knight (1921) distinction between risk and true uncertainty Uncertainty when probability distribution is itself unknown Uncertainty, by its nature, cannot be measured and is uninsurable But is the result of measurable economic changes. Not much attention in the empirical asset pricing literature

3 Conditional ICAPM with Risk and Uncertainty Merton s ICAPM: µ = A σ + B σ i im ix We examine conditional ICAPM with time-varying covariances: ER [ Ω ] = A cov[ R, R Ω ] + B cov[ R, X Ω ] it, + 1 t it, + 1 mt, + 1 t it, + 1 t+ 1 t Investors are concerned with Terminal wealth of portfolio Future consumption and investment opportunities.

4 Economic uncertainty index Jurado, Ludvigson, and Ng (2015) Uncertainty: conditional volatility of innovations 132 macroeconomic time series Real output and income Employment and hours Real retail, manufacturing and trade sales Consumer spending Housing starts etc. Computed on a one month, three month and one year basis

22 Hedge fund application Economic uncertainty exposure explains hedge fund returns A significant relation between future returns and exposure to uncertainty Effect is greatest for directional fund strategies: R = δ ( δ ) it, 1 it, it, it, it, δ (2.78) (2.00) (0.94) (2.03) = 1 if fund is directional, δ = 0otherwise it, i it, Turan Bali, Stephen Brown and Mustafa Caglayan Macroeconomic risk and hedge fund returns Journal of Financial Economics 114(1)

23 Conclusion Uncertainty is both measurable and material Is distinct from market volatility Is associated with a negative premium in stock returns Stocks differ in their sensitivity to this factor Systematic differences in sensitivity by industry Uncertainty affects consumption and investment Increased uncertainty => unfavorable investment opportunities Uncertainty premium is higher in times of economic distress
