Is information risk priced? New evidence from outer space

ABSTRACT:

Satellite images of the parking lots of US retail firms provide information about the firms’ future earnings, and the limited access to these images produces information asymmetry between sophisticated and unsophisticated investors. We construct a cloud-based information risk (CIR) measure to capture this satellite information risk and investigate its asset pricing performance. We find that cloud cover over retailers’ parking lots negatively predicts future stock returns of retail firms in cross section and the predictability cannot be explained by weather reasons. Furthermore, retail firms with less cloud cover are more heavily shorted by informed traders than firms with more cloud cover. The pricing ability of this CIR measure is stronger prior to earnings announcements. Liquidity is the primary channel through which CIR affects equity premiums.
