Volatility: How Much Prices Swing
Volatility measures how much a price moves up and down. It is not the same as losing money, but it tests your nerves.
Why this matters for beginners
Understanding this helps you stay calm and read price moves correctly. This is general education, not personal advice.
Main explanation
A share that often moves 4 percent in a day is more volatile than one that moves 0.5 percent.
Young, fast-growing or small companies are usually more volatile than large, steady ones.
High volatility means a wider range of outcomes, in both directions.
If big swings would make you sell in a panic, volatile shares may not suit you.
Example using a real company
Tesla has often moved several percent in a single day, while Coca-Cola usually moves far less.
- →Share A: 100, 98, 101, 99. Low volatility.
- →Share B: 100, 90, 112, 95. High volatility, same start and similar end.
