The Securities and Exchange Commission is now accepting comments on two short selling disclosure requirements, in order to inform an agency study by the Dodd-Frank Act, the Commission said today in a statement.

Under the provision, the study must evaluate two possible disclosure systems. The first, a “transactions reporting regime,” would add short sale-related marks to the consolidated tape, which is the electronic system that constantly reports the price and volume of stock sales.This first proposed regime would initially be tested out through a voluntary pilot program. The second proposal is for a “position reporting regime,” which would mean real-time reporting of investors’ short positions to the public or only to regulators.
