New proposals from the US Securities and Exchange Commission (SEC) would force hedge funds and other large investors would have to disclose significantly more information about the stocks they short, according to a report by Pensions & Investments.

Proposed Rule 13f-2 and Form SHO would mean that money managers would the to submit monthly filings to the regulator outlining large equity short positions. While information such as the identity of fund managers and their individual positions would remain confidential, the SEC says it would make some aggregate data about individual equity large short positions available to the public. 

The proposed changes would apply to all managers holding a short position of at least USD10 million, or 2.5 per cent of the shares outstanding.
