Although exchange-listed stocks can be traded OTC on the third market, it is rarely the case. Usually OTC stocks are not listed nor traded on exchanges, and vice versa. Although stocks quoted on the OTCBB must comply with U.S. Securities and Exchange Commission (SEC) reporting requirements, other OTC stocks have alternative disclosure guidelines (for example, OTCQX stocks through OTC Market Group Inc), and others have no reporting requirements, for example Pink Sheets securities.
