Penny Stock
A very low-priced small stock (usually under $5 per share) — an area where volatility and the risk of manipulation or fraud are high, so beginners need extra care.
Penny stock = a very low-priced, very small stock (in the US, typically under $5 per share) · thin trading and little information mean high volatility and manipulation risk
Penny stocks can surge on a small piece of good news or a rumor and then collapse in an instant — an extremely volatile pattern.
In plain terms
A penny stock is, literally, a stock priced at just "a few pennies" — a very low price per share. In the US, anything under $5 is usually called a penny stock. The companies are often small and little known.
Thinking that a low price per share means you are "getting good value" is risky. Penny stocks can swing sharply on small amounts of money, and with little information available they are easy targets for manipulation and fraud.
What it tells you
Penny stocks show starkly that "a low price and a low value are different things." A low price per share is often a sign that the company is small or in poor shape.
With thin trading volume and scarce public information, this is an area where a small group can easily push the price up and then dump it (pump and dump).

What high or low means
Penny stocks can surge on a small piece of good news or a rumor and then collapse in an instant — an extremely volatile pattern. The lure of large gains comes with an equally large risk of loss.
In many cases the company itself is in poor shape or at risk of delisting. The reason behind a low share price differs from company to company.
The idea that "the price is low, so if I buy a lot, I'll hit it big when it rises" is the most dangerous one. Penny stocks are easy targets for manipulation schemes and fraud, and the structure where whoever gets in last bears all the losses is common. (This is a concept explanation, not a trading recommendation.)
A low share price is often a "warning" rather than an "opportunity." A solid company whose price fell because of a stock split is an entirely different thing from a penny stock whose price is low because the business is doing badly.
