The Effect of Mandated Market Risk Disclosures on Trading Volume Sensitivity to Interest Rate, Exchange Rate, and Commodity Price Movements
Posted: 26 Nov 2001
We hypothesize that firms' 10-K market risk disclosures, recently mandated by SEC Financial Reporting Release No. 48 (FRR 48), reduce investors' uncertainty and diversity of opinion about the implications, for firm value, of changes in interest rates, foreign currency exchange rates, and commodity prices. We argue that this reduced uncertainty and diversity of opinion should dampen trading volume sensitivity to changes in these underlying market rates or prices. Consistent with this hypothesis, we find that after firms disclose FRR 48-mandated information about their exposures to interest rates, foreign currency exchange rates, and energy prices, trading volume sensitivity to changes in these underlying market rates and prices declines, even after controlling for other factors associated with trading volume. The observed declines in trading volume sensitivity are consistent with FRR 48 market risk disclosures providing useful information to investors.
