19c-3 stock(redirected from 19c3 Stocks)
A stock listed on a given exchange that may be traded off the physical confines of the exchange. These stocks are eligible for over-the-counter trading. All stocks listed after April 26, 1979 are 19c-3 stocks. The name refers to SEC rule 19c-3, which permitted these transactions. The rule was adopted as part of a move toward an experimental National Market System.
A stock that may be traded by an exchange member as well as on an exchange because it was listed after April 26, 1979. Prior to this date, exchange members were prohibited from making a market in exchange-listed securities. Thus, the change permits a member of an exchange to act as principal in making a market in a 19c-3 stock as well as to act as an agent in trading on the floor. This stock is named for SEC Rule 19c-3 that permits off-board trading.
