Abstract
Liu et al. (2004, this issue) show that technical sophistication and learning over time help improve the ability of bank trading portfolios' value-at-risk (VaR) disclosures to predict future trading income risk, and that trading VaRs predict bank-wide total risk and systematic risk. While the results suggest that VaRs are a reliable measure of risk for the sample firms, the study's incremental contribution is limited because of the nature of the sample firms and problems in variable measurement.
