The National Association of Securities Dealers (NSAD) has proposed that Wall Street analysts more prominently disclose ownership in companies they cover, including making such disclosures during TV interviews and other public appearances. Firms would also have to offer more visible disclosure of their investment-banking relationships. The proposal, subject to Securities and Exchange Commission approval, is the latest effort to address the conflicts of interests of analysts, an issue that has gained momentum recently due to highly touted tech stocks crashing. Congress has recently held meetings regarding the issue, and the Securities Industry Association unveiled a set of so-called best practices for Wall Street firms to follow.
