In the past, penny stocks were considered any stocks that traded for less than one dollar per share. The U.S. Securities and Exchange Commission (SEC) has modified the definition to include all shares trading below five dollars. The SEC is an independent federal government agency responsible for protecting investors as they maintain fair and orderly functioning of the securities markets.
Penny stocks are usually associated with small companies and trade infrequently meaning they have a lack of liquidity or ready buyers in the marketplace. As a result, investors may find it difficult to sell stock since there may not be any buyers at that time. Because of the low liquidity, investors might have difficulty finding a price that accurately reflects the market.
Due to their lack of liquidity, wide bid-ask spreads or price quotes, and small company sizes, penny stocks are generally considered highly speculative. In other words, investors could lose a sizable amount or all of their investment.
