A 19c3 stock is a stock that is listed on one of the national exchanges after April 16, 1979. The term "19c3 stock" refers to SEC rule 19c3 which permits member firms to make dealer markets in so-called "19c3 stock" away from the exchange trading floor. The SEC's intent in enabling 19c3 stock trading was supporting the creation of a National Market System where market professionals could interact with their counterparts in other markets. The pilot NMS program consisted of 30 19c3 stock listings. Today, the majority of NYSE-listed companies are 19c3 stock. Investors can identify whether a company is a 19c3 stock by visiting the web site of the exchange where the shares are listed. Information regarding the date the company listed is provided. |
