A security is a tradable financial asset. The term commonly refers to any form of financial instrument, but its legal definition varies by jurisdiction. In some countries and languages people commonly use the term "security" to refer to any form of financial instrument, even though the underlying legal and regulatory regime may not have such a broad definition. In some jurisdictions the term specifically excludes financial instruments other than equities and fixed income instruments. In some jurisdictions it includes some instruments that are close to equities and fixed income, e.g., equity warrants.
A market maker or liquidity provider is a company or an individual that quotes both a buy and a sell price in a tradable asset held in inventory, hoping to make a profit on the bid–ask spread, or turn.

Penny stocks are common shares of small public companies that trade for less than one dollar per share. The U.S. Securities and Exchange Commission (SEC) uses the term "Penny stock" to refer to a security, a financial instrument which represents a given financial value, issued by small public companies that trade at less than $5 per share. Penny stocks are priced over-the-counter, rather than on the trading floor. The term "penny stock" refers to shares that, prior to the SEC's classification, traded for "pennies on the dollar". In 1934, when the United States government passed the Securities Exchange Act to regulate any and all transactions of securities between parties which are "not the original issuer", the SEC at the time disclosed that equity securities which trade for less than $5 per share could not be listed on any national stock exchange or index.
