What is a penny stock, and are they worth buying?
A stock trading under about $5, often on lightly regulated markets. Cheap price does not mean cheap value, and the segment is full of thin trading, hype and outright fraud. Beginners are usually better off avoiding them.
A penny stock is shorthand for shares of a small company trading at a very low price, usually under $5, often under $1. Many are not on the main exchanges at all but on over-the-counter markets with lighter disclosure rules. The appeal is obvious: a 30-cent stock only needs to reach 60 cents to double your money.
The problem is that a low share price says nothing about value. A company with a billion shares at 30 cents is worth $300 million, the same as one with 10 million shares at $30. What the low price usually signals is a small, often unprofitable business that could not or would not meet the standards of a main exchange.
The segment also attracts manipulation. "Pump and dump" schemes, where promoters hype a thin stock, sell into the buying they create and leave everyone else holding it, are a penny-stock speciality. Thin trading means the price can move 50 percent on a small order, and it can be hard to sell at all when you want out.
If you want exposure to small companies, a small-cap index fund gives you thousands of them with real disclosure and none of the fraud risk. If you want to gamble on one penny stock for fun, size it as a lottery ticket and expect the same outcome.
