Here’s Why.
It’s a number that’s hard to ignore heading into the end of financial year.
Over the last twelve months, the Australian market has ground out roughly 0.5%. The S&P 500 is up 22% over the same period. That’s not a rounding error. That’s a structural gap — and it comes down to one thing more than anything else.
The AI Difference
The US market’s performance over the past year has been driven by a relatively small group of companies sitting at the centre of the artificial intelligence story. Strip those out of the S&P 500, and the picture looks very different.
Australia simply doesn’t have an equivalent. The ASX is heavily weighted toward banks, resources, and traditional income-producing sectors. Solid businesses. Reliable dividends. But not the kind of high-growth, technology-driven earnings that have been pulling US indices higher.
That structural difference explains the gap far better than any single event or policy decision.
Why This Pattern Is Consistent
This isn’t the first time we’ve seen this dynamic. When markets are being led by a concentrated group of growth companies — as they are right now — Australia tends to lag.
We don’t have the tech sector. We don’t have the scale of capital flowing into AI-adjacent businesses. And our investment culture, broadly speaking, leans toward income and stability rather than growth and disruption. That’s not a flaw. It’s just a different market with different characteristics.
The Risk of Home Bias
There’s a natural tendency for Australian investors to gravitate toward what they know. Local companies, familiar brands, sectors they understand. That comfort is understandable. But familiarity isn’t a strategy.
An investor who has been predominantly Australian over the past twelve months has experienced that 0.5% return while a globally diversified portfolio would have captured meaningful upside elsewhere. That’s the real cost of home bias — not a theoretical argument, but a lived outcome.
What the Gap Actually Tells You
The US versus Australia comparison isn’t an argument for abandoning Australian investments. There are things this market does well — income, resource exposure, franking credits — that global markets don’t replicate.
But it is a clear reminder that where you invest matters just as much as how you invest. Overexposure to any single market, including your own, concentrates risk in ways that aren’t always visible until the numbers come in at year end.
The Takeaway Heading Into July
As we approach June 30, the performance gap is a useful prompt — not for regret, but for review. Is your portfolio positioned to capture growth wherever it happens to be? Or is it concentrated in familiar territory at the expense of opportunity?
That’s a question worth sitting with before the new financial year begins.
