Penny stock Investment are stocks of those companies that trade with a share price that is below $5; however, often penny stocks can be less than $1, as the name suggests. The extremely low share prices allow an investor to hold thousands of shares for a relatively small amount of invested capital. With that scale, the gain of just a few cents per share can translate into sizable percentage returns; however, it is important to note the reverse is also true, of course.
These stocks are traded on regular exchanges such as the Nasdaq. However, major stock exchanges, such as the NYSE and Nasdaq, have special listing requirements. For example, according to Nasdaq Rule 5550(a), failure to have a minimum bid price of at least $1 per share for primary equities will result in being delisted.
