The Spanish Statistical Office (INE) has just announced a sharp downward revision of the GDP growth rate it announced before summer in its flash estimate. The reason given for such an aggressive revision is that the pandemic has distorted data gathering, but this type of significant review of data is rare. A statistical revision of this magnitude, in the case of a listed company in its earnings release, would put into question its reliability and cause research analysts to increase the risk premium applied to the discount rate.
