What are low float stocks?

Low float stocks are the stocks of companies with pretty high institutional ownership that are left for trading on the market. For example – if a company has total outstanding shares of 100 million and the restricted stocks (also known as closely-held) are 90 million, it means that just 10% (10 million) of all shares are low float stocks and are available for public trading.

Usually, companies issue closely-held stocks which are owned by major stakeholders, employees or other insiders. The minority left for public trading (usually 10% – 15%) are low float stocks.
