We study the effect of the Securities Exchange Act of 1934 on common stock bid-ask spreads and other information measures. Among other things, the 1934 Act mandated a complete, audited income statement and balance sheet. Prior to the 1934 Act, some firms disclosed sales or depreciation, and some chose not to. Some firms reported audited financials; some did not. If disclosures and audits reduce information asymmetries, the 1934 Act should have a differential effect across these stocks. We find that a firm's disclosure status in 1933 has little to do with the evolution of its information measures. Overall, we find that cross-sectional differences in mandatory disclosure had little measurable effect on the degree of information asymmetry.
