Regulation M (Trading in Connection with Offering)


This page provides material material on the SEC's Regulation M, which limits trading that may have a manipulative effect during the course of a securities offering, as well as certain related obligations. Although most of this material is focused on distribution participants, investors are generally prohibited from selling short in anticipation of an offering and then covering out of the offering. Accordingly, the requirements on this page also overlap to some extent with requirements as to the short selling of securities.'s picture
