10 largest insurance companies in Australia

What is market capitalisation?

Market capitalisation, also referred to as market cap, pertains to the total value of a publicly traded company’s outstanding common shares owned by stockholders. This metric indicates how much a business is worth as determined by the stock market. You can calculate a company’s market cap by multiplying the number of outstanding shares by the current market value of a single share. For this list, we pulled market capitalisation data from the ASX website.

Why is market cap important?

A firm’s market capitalisation plays an essential role in determining its size, without having to gather data about its sales figures or total assets. Investors often use market cap to evaluate a company’s financial performance against firms of varying sizes. This metric tells them if a business presents a safe or risky investment opportunity.

Firms with a large market cap are typically financially stable and carry less risk for investors. Companies with smaller caps, on the other hand, are often riskier to invest in but offer huge potential rewards, especially if they post tremendous growth.

But what does market cap mean for the insurance community? Market cap can help insurance professionals and customers understand if an insurer is secure enough to meet its financial obligations. For those looking for a job in insurance, large cap companies can also provide a stable workplace.

Australian insurers, however, account for a small portion of the world’s insurance giants. If you want to find out the largest insurance companies in the world, you can check out our latest global rankings of the largest insurance companies in the world.
