Microcap stock (Ofer Abarbanel online library)

The term microcap stock (also micro-cap) refers to the stock of public companies in the United States which have a market capitalization of roughly $50 million to $300 million. The shares of companies with a market capitalization of less than $50 million are typically referred to as nano-cap stocks. Microcap stocks are different from other stocks since they are from companies with a small market capitalization and are usually traded on stock exchanges that do not require minimum standards, such as a minimum amount of net assets or a minimum number of stock holders.[1]

In addition, these micro cap stock companies often have fewer resources to make their information available to the public.[2] These micro cap stocks are less likely to be published and talked about by stockbrokers compared to larger public companies. Often, microcap stock companies will specialize in innovative products or services that may be unknown to the general public.[3]

Many micro-cap and nano-cap stocks are traded over-the-counter with their prices quoted on the OTCBB, OTC Link LLC, or the Pink Sheets. The larger, more established micro-caps are listed on the NASDAQ Capital Market or American Stock Exchange (AMEX).

Micro-cap and especially nano-cap stocks can sometimes experience volatility. Some of these companies fail to execute their business plans and go out of business. Fraud and market manipulation are not uncommon and the transaction costs in trading can be quite high. Pricing is more likely to be inefficient, since fewer institutional investors and analysts operate in this space, due to the relatively small dollar amounts involved and the lack of liquidity.
