Pinksheets: A slang term used to refer to the Over-The-Counter (OTC) market. Companies trading in this market are not required by law to file reports, which makes it a riskier investment than those found on established and regulated exchanges such as the NYSE and NASDAQ. However, pinksheets can potentially offer great returns with high levels of liquidity, making them attractive for savvy investors who understand the risks and know how to identify potential opportunities.
