Penny Stock
A very low-priced small-cap stock (usually under $5) — with high volatility and a big risk of manipulation and fraud, an area that needs special caution from beginners.
In plain terms
A penny stock is literally a stock priced as cheaply as "a few pennies." In the US, anything under about $5 is usually called a penny stock. The companies are often small and little known.
Thinking "I am buying cheap" because the price is low is dangerous. A penny stock swings hard even on small money, and with little information it is an easy target for manipulation and fraud.
What it tells you
Penny stocks vividly show that "a cheap price and cheap value are different." A low per-share price is often a signal that the company is small or weak.
With thin trading and scarce public information, it is an area where a few players can easily pump the price up and dump it (pump and dump). So it is one of the places beginners must be most careful about.
Formula
penny stock = a very low-priced micro-cap stock (typically under $5 in the US) · thin trading and scarce information make volatility and manipulation risk high
What high or low means
Penny stocks show extreme volatility, spiking on small good news or rumor and then crashing in an instant. The lure of big gains comes with a big risk of big losses.
The company itself is often weak or near delisting, so you must always ask "why is it this cheap."
"It is cheap, so buy a lot and hit it big when it rises" is the most dangerous idea. Penny stocks are easy targets for manipulation and fraud, and a structure where the last one in bears all the loss is common. (This is a concept explainer, not a trading suggestion.)
A low price is often a "warning," not an "opportunity." A quality stock made cheap by a stock split and a penny stock cheap because the company is weak are completely different.
