NEW HAVEN, Conn., May 3 /PRNewswire/ -- Regulation Fair Disclosure (FD)
prohibits U.S. firms from disclosing information to only a select few
analysts, instead requiring disclosures to the public. Although the Securities
and Exchange Commission enacted Regulation FD with the aim of improving the
quality of information reaching the market to help level the playing field
between investors and analysts, it may have the opposite effect according to a
The study "Unintended Consequences of Regulating Disclosures: The Case of
Regulation Fair Disclosure" finds that by forcing disclosures to be widely
disseminated, Regulation FD may unwittingly increase herding behavior, the
tendency for analysts to quickly converge to a consensus, and consequently
leave investors less informed and worse off. As a result of this concern,
firms with investors' priorities in mind may withhold disclosure, and
therefore, Regulation FD may inhibit the very disclosure it was intended to

The researchers modeled the effects of Regulation FD on analyst
interactions and the resulting implications for both investors and firms.
Among the findings: if a firm's disclosure is public, analysts may rationally
mimic the firm's announcement and ignore their own information. As a result,
an investor is left with only firm information to guide her decisions.
The study also finds that private disclosure can delay herding and result
in an investor having access to more diverse information, despite not having
direct access to the firm's information. For example, an investor will have
access to both the information of analysts who were not privy to the firm's
disclosure and therefore reported their own information, as well as the
information from analysts who did receive the disclosure.
"Selective disclosures can have the advantage of staving off herding
behavior. And while selective disclosures limit investors' access to
information initially, the postponement of herding may mean investors gain in
the end," according to Professor Narayanamoorthy.
Professor Mittendorf concluded, "Though Regulation FD was created with an
eye on curbing the behavior of financial market miscreants, our research shows
that the limitations inherent in the regulation may harm firms and analysts
whose intentions are pure. By fixating on the wrongdoings of a few, Regulation
FD may be at risk for throwing the baby out with the bath water."
