In the U.S., over-the-counter trading in stock is carried out by market makers that make markets in OTCBB and Pink Sheets securities using inter-dealer quotation services such as Pink Quote (operated by Pink OTC Markets) and the OTC Bulletin Board (OTCBB). OTC stocks are not usually listed nor traded on any stock exchanges, though exchange listed stocks can be traded OTC on the third market. Although stocks quoted on the OTCBB must comply with U.S. Securities and Exchange Commission (SEC) reporting requirements, other OTC stocks, such as those stocks categorized as Pink Sheets securities, have no reporting requirements, while those stocks categorized as OTCQX have met alternative disclosure guidelines through Pink OTC Markets.
