Global Share Market Comparison: Why It Pays to Look Beyond the Headline ASX Index

Global Share Market Comparison: Why It Pays to Look Beyond the Headline ASX Index

· Updated 17 Jun 2026 ·

Quick Answer

Out of the major global share market indices, leadership rotates often. At one point Japan’s TOPIX has led 12-month returns. What is also worth seeing is the size of individual companies inside each market: Nintendo, for example, has at times been comparable in market cap to one of Australia’s Big Four banks. Indices are buckets of very different companies, and ‘the market’ is rarely homogeneous.

Key Takeaways

  • 12-month leadership across global indices rotates often. The leader this year is rarely the leader next year.
  • Japan's TOPIX has led on a 12-month basis at recent points in time.
  • Inside any market, single-company size can surprise: Nintendo has at times been comparable in market cap to one of the Big Four Australian banks.
  • Indices are buckets of very different companies. 'The market' is rarely homogeneous.
  • The takeaway is to look beyond a single index when thinking about diversification.

Out of the major global sharemarket indices, leadership shifts more than most investors realise. At one point in time, Japan’s TOPIX has led on 12-month returns. The point of noticing this is not to chase whichever region is on top. It is to remember that ‘the market’ is shorthand for many different markets that behave differently in any given year.

What companies actually make up these markets?

It is worth pausing on what is inside the indices we talk about. As one example, looking at the Japanese market by market capitalisation (share price multiplied by number of shares, in USD) reveals that Nintendo has at times been comparable in market cap to one of Australia’s Big Four banks.

That sort of comparison is hard to imagine if you only think in headlines. It also tells you something useful: indices are buckets of very different businesses, with very different drivers, all stitched together under one number. Two investors with ‘the same exposure’ to a region can end up with quite different outcomes depending on which sub-segments they actually own.

What this means for an Australian investor

If you hold global equity exposure (directly, through ETFs, or inside super), it is worth understanding what is actually in there. The leader rotates. The composition matters. And single-name concentration can hide inside a passive vehicle if you do not look.

What to do next

Pull a fact sheet for one global equity holding you own. Look at the top 10 names. Ask whether the regional and single-name exposure inside it is consistent with how you describe your portfolio out loud.
