Pink sheets and penny stocks
There's a fair amount of overlap between pink sheet stocks and penny stocks. Many penny stocks (shares that trade for $5 or less) are pink sheet stocks, though pink sheet stocks also include higher-priced shares that don't meet regulatory requirements for trading on an exchange. Still, many pink sheet stocks are penny stocks themselves.
The key distinction is that "pink sheets" refers to how a stock is traded (over-the-counter). "Penny stocks" refers to the share price of a given company (less than $5 per share).
While most penny stocks are considered speculative, not all pink sheet stocks are speculative. There are a variety of reasons why a company may trade off the exchange; many companies that trade over-the-counter are financially sound.
The pink sheets don't have particularly stringent regulatory requirements, which explains why you'll find penny stocks listed there. A lack of reporting standards makes investing in pink sheet stocks a risky endeavor. It's also why you'll find a large population of penny stocks as part of the pink sheet roster.
When can I buy pink sheet stocks?
Pink sheet stocks can usually be traded from Monday through Friday between 6 a.m. and 5 p.m. ET. This window differs from those of the major U.S. exchanges, which are open between 9:30 a.m. and 4 p.m. ET on weekdays.
Is there a difference between pink sheets and OTC?
Stocks that trade over the counter are broadly referred to as "pink sheets," but the term technically has a more specific meaning. All pink sheet stocks trade over the counter through dealer networks. But not all OTC-traded stocks are listed by OTC Markets Group, the publisher that originally used pink sheets.
Companies that adopt a certain set of regulatory and reporting standards are listed by the Over the Counter Bulletin Board (OTCBB) system, while companies that adhere to a stricter set of standards can list through the OTCQX. While stocks that trade over the counter are broadly referred to as "pink sheets," the risk profiles of these stocks can vary greatly.
