When markets go up and down it can make us feel nervous about our money. Here’s what to know about market volatility, using the share market as an example.

Volatility is how the return on an asset fluctuates over time. Using the share market as an example, volatility is often measured by changes in the price of a share. When the market is volatile, prices can rise or fall a lot in a short time.

These movements mean the value of your investments can change quickly. They might rise in value one day and fall the next.

Volatility can make us feel nervous, but short-term ups and downs happen often in share markets. Over long periods, markets have moved through many cycles of rises and falls.

Check out this chart from the Australian Securities Exchange (ASX) showing an example of Australian share price movements between 1995 and 2025.

What causes share market volatility?

As the ASX chart linked in the smart tip box shows, a lot of factors can move share prices quickly.

Share markets respond to new information such as economic data, company results and global events. Investors react to this information by buying and selling shares, which moves prices.

Economic data often affects the market. Changes in interest rates, inflation or economic growth can shape how investors view the future performance of companies.

Global events also influence markets. Political decisions, trade changes or international conflicts can create uncertainty for investors.

Investor behaviour can also drive volatility. When many investors feel nervous, they may sell shares at the same time, which can push prices down. When investors feel more confident, they may buy more shares and push prices up.

Because new information appears all the time, the price of listed shares can change frequently.
