At some point, almost every Australian investor asks the same question: Should I stick to the ASX, or should I be putting money into the US share market? (ASX vs US)
It is a fair question. The US market is home to some of the most powerful companies in the world — Apple, Microsoft, Amazon, Nvidia, and Google, among them. Meanwhile, the ASX offers something the US does not: fully franked dividends and home-market familiarity.
The honest answer is that this is not really an either/or decision. Most experienced Australian investors hold both. But understanding the meaningful differences between the two markets helps you make a smarter allocation decision — and avoid common mistakes that come from diving into one without understanding the other.
This guide breaks down everything you need to know to make that call confidently.

Understanding the Two Markets
Before comparing them side by side, it helps to understand what each market actually looks like.
The Australian Securities Exchange (ASX)
The ASX lists over 2,000 companies and has a total market capitalisation of approximately AUD $3 trillion. It is dominated by financial services, resources, and consumer staples — sectors that reflect Australia’s economic structure.
The top 20 ASX stocks by market cap include the four major banks, BHP, Rio Tinto, CSL, Wesfarmers, Woolworths, and Macquarie. Together, these companies represent a large portion of the index’s total value.
This concentration means the ASX is not as diversified as it might seem at first glance. If you own the ASX 200, you are heavily exposed to banks and miners — whether you intended to be or not.
The US market is the largest in the world by a significant margin. The New York Stock Exchange (NYSE) and NASDAQ combined represent over USD $50 trillion in market capitalisation — more than all other global markets combined.
The US market is far more diversified across sectors than the ASX. Technology companies like Apple and Microsoft alone are each worth more than the entire ASX. The US also leads the world in healthcare innovation, consumer brands, financial services, and defence.
For Australian investors, accessing US stocks is done either through international brokers that provide direct access, or through ASX-listed ETFs that track US indices — making it more accessible than many beginners realise.
ASX vs US Stocks: Head-to-Head Comparison
| Feature | ASX | US Market |
|---|---|---|
| Market size | ~AUD $3 trillion | ~USD $50+ trillion |
| Number of listed companies | ~2,000+ | ~6,000+ |
| Dominant sectors | Banks, mining, consumer staples | Technology, healthcare, financials |
| Average historical annual return | ~10% (including dividends) | ~10–11% (S&P 500 long-term) |
| Dividend yields | Higher (3–5% average) | Lower (1–2% average) |
| Franking credits | Yes — unique Australian tax advantage | No |
| Currency risk for Australians | None | Yes — AUD/USD exposure |
| Regulatory oversight | ASIC | SEC |
| Time zone alignment | Local hours | Overnight for Australians |
| Access for Australians | Direct via ASX broker | Via international broker or ASX-listed ETF |
This table is a useful starting point, but each row deserves a deeper look.
Returns: Which Market Has Performed Better?
This is the question most investors ask first, and the answer is nuanced.
Long-Term Historical Returns
Over the long term, both markets have delivered comparable total returns when dividends are included. The US S&P 500 has averaged approximately 10 to 11 per cent per year over the past several decades. The ASX All Ordinaries has delivered similar figures when you include the substantial dividends Australian companies pay.
However, the composition of those returns differs significantly. ASX returns are more income-driven — a larger portion comes from dividends. US returns are more growth-driven — a larger portion comes from share price appreciation, particularly from technology companies.
The Technology Factor
The single most important reason US stocks have captured Australian investors’ attention over the past 15 years is the dominance of US technology companies.
Apple, Microsoft, Amazon, Alphabet, Meta, and Nvidia have produced extraordinary gains over the past decade. The ASX has no equivalent cluster of global technology leaders. Australia’s tech sector is smaller, younger, and far less influential on the overall index.
An investor who held the NASDAQ 100 over the past 10 years significantly outperformed a purely ASX-focused investor on a capital growth basis. However, past performance does not guarantee future returns — and technology sector valuations can be highly stretched during bull markets.
The Dividend Advantage of the ASX
Where the ASX consistently outperforms on paper is in dividend yield. Australian companies — particularly banks and resource companies — pay significantly higher dividends than their US counterparts.
The average dividend yield on the ASX 200 is typically between 3.5 and 5 percent, compared to around 1.3 to 1.5 percent for the S&P 500. And crucially, those ASX dividends often come with franking credits — a tax advantage that does not exist anywhere else in the world.
Franking Credits: The ASX’s Unique Advantage
No comparison between ASX and US stocks for Australian investors is complete without a serious discussion of franking credits.
What Are Franking Credits?
When an Australian company pays tax on its profits and then distributes those profits as dividends, it attaches tax credits to the dividend. These are called franking credits (or imputation credits). They represent the tax the company has already paid on your behalf.
As an Australian resident investor, you can use those franking credits to offset your own income tax liability. If your credits exceed your tax liability, the ATO refunds the difference — meaning you can actually receive cash back from the government simply for holding ASX dividend stocks.
A Simple Example
Imagine you receive a $700 fully franked dividend from CBA. Attached to that dividend is a $300 franking credit (representing the 30% company tax already paid). Your total assessable income from this dividend is $1,000.
If your marginal tax rate is 32.5%, your tax on the $1,000 is $325. But you have a $300 franking credit to offset that — so you only owe $25 in tax. If you are in a lower tax bracket, you might owe nothing and receive a refund.
This advantage is exclusive to Australian-listed stocks and has no equivalent when investing in US shares.
Currency Risk: The Hidden Cost of US Investing
When an Australian buys US stocks — either directly or through an unhedged ETF — they are exposed to movements in the AUD/USD exchange rate. This is called currency risk, and it cuts both ways.
When Currency Risk Works in Your Favour
If the Australian dollar weakens against the US dollar, your US investments become worth more in AUD terms — even if the underlying stock price has not moved. A 10% depreciation in the AUD effectively adds 10% to your US returns when converted back to Australian dollars.
When Currency Risk Works Against You
Conversely, if the AUD strengthens, your US investments lose value in AUD terms when you convert them back. A strong year on the S&P 500 can be partially or fully eroded by a rising Australian dollar.
Over the very long term, currency effects tend to even out. But in the short to medium term, they can meaningfully affect your returns in either direction.
Hedged vs Unhedged ETFs
If you want US market exposure without currency risk, some ASX-listed ETFs offer currency-hedged versions. For example, iShares offers both a standard S&P 500 ETF (IVV) and a hedged version (IHVV). The hedged version aims to deliver US market returns without the AUD/USD variability.
| ETF Type | Currency Exposure | Best For |
|---|---|---|
| Unhedged (e.g., IVV) | Yes — AUD/USD movements affect returns | Long-term investors comfortable with FX risk |
| Hedged (e.g., IHVV) | Minimised — FX movements mostly neutralised | Investors who want pure market exposure |
Tax Considerations: ASX vs US Stocks
Beyond franking credits, there are other tax differences Australian investors need to understand.
Dividends from US Stocks
US companies do not pay franking credits. Additionally, the US government withholds 15% tax on dividends paid to Australian investors under the Australia-US tax treaty (the withholding rate can be higher without a tax treaty).
This means if you receive $100 in dividends from a US stock, you only receive $85 after withholding. You can claim this withholding as a foreign tax offset in your Australian tax return, but the process is more complex than simply receiving a fully franked ASX dividend.
Capital Gains Tax
The 50% CGT discount for assets held more than 12 months applies to both ASX and US investments for Australian residents. From a CGT perspective, there is no structural difference between the two markets.
Reporting Complexity
Investing directly in US stocks — as opposed to through an ASX-listed ETF — adds complexity to your tax return. You need to report foreign income, calculate foreign tax offsets, and potentially deal with different reporting requirements. Using an ASX-listed ETF that tracks US indices simplifies this significantly.

Sector Diversification: Why Owning Both Makes Sense
One of the most compelling arguments for holding both ASX and US stocks is sector diversification.
The ASX is structurally overweight in financials and resources. These sectors make up a disproportionately large share of the index compared to their weighting in global markets. The ASX is structurally underweight in technology and healthcare relative to global benchmarks.
The US market provides what the ASX lacks. Adding US exposure gives Australian investors access to the world’s leading technology companies, global consumer brands, and a far broader healthcare sector — none of which are adequately represented on the ASX.
| Sector | ASX Weight (approx.) | S&P 500 Weight (approx.) |
|---|---|---|
| Financials | ~30% | ~13% |
| Materials / Resources | ~20% | ~3% |
| Healthcare | ~10% | ~13% |
| Information Technology | ~5% | ~29% |
| Consumer Discretionary | ~7% | ~10% |
| Energy | ~4% | ~4% |
| Other | ~24% | ~28% |
Approximate weightings — subject to change as markets evolve.
This table illustrates the point clearly. An investor who only holds the ASX has almost no technology exposure and a fraction of the healthcare exposure available through US markets. An investor who only holds the US market misses the income advantages and franking credits of Australian stocks.
What Do Most Australian Financial Advisers Recommend?
While this article is educational and not financial advice, it is worth noting the general consensus that emerges from the financial planning community in Australia.
Most Australian financial planners recommend a diversified portfolio that includes both domestic (ASX) and international (primarily US) exposure. A common starting allocation for an Australian investor might look something like this:
- 40–60% Australian shares: For franking credits, dividend income, and home-market familiarity
- 30–50% International shares: Primarily US exposure for technology and growth diversification
- Remainder: Bonds, property, or other assets, depending on risk profile
The exact split depends on your age, income, risk tolerance, and investment goals. Younger investors with longer time horizons often tilt more towards international growth. Investors seeking income — particularly retirees — often tilt more towards ASX dividend stocks for the franking credit benefit.

Practical Ways to Access Both Markets
ASX Stocks
Accessible through any ASIC-regulated Australian online broker. You buy shares in Australian dollars, no currency conversion required, and dividends are paid in AUD.
US Stocks Directly
Platforms like Stake, Interactive Brokers, and CMC Markets offer direct access to US-listed shares. You will need to convert AUD to USD and complete a W-8BEN form (a US tax declaration for non-US investors).
US Exposure via ASX-Listed ETFs
The simplest approach for most beginners. ETFs like IVV (S&P 500), NDQ (NASDAQ 100), and VGS (Vanguard Global Shares, which is heavily US-weighted) give you US market exposure without needing a separate international account, currency conversion, or additional tax complexity.

Conclusion
The ASX vs US stocks debate is less of a competition and more of a portfolio construction question. Both markets offer genuine advantages that the other cannot replicate.
The ASX gives you franking credits, higher dividend yields, and home-market familiarity. The US gives you technology leadership, deeper diversification, and the world’s most liquid share market.
For most Australian investors, the smartest answer is to own both — using ASX holdings for income and tax efficiency, and US exposure (via ETFs or direct holdings) for growth and global diversification. Start with what you understand, learn as you go, and build a portfolio that reflects your goals rather than a loyalty to one market over the other.
Frequently Asked Questions (FAQs)
Should Australian investors buy ASX or US stocks?
Most financial educators recommend holding both. The ASX offers franking credits and high dividend yields, while the US market provides superior technology exposure and broader diversification. Combining both gives you income efficiency and growth potential.
Are US stocks better than ASX stocks for long-term growth?
US technology stocks have significantly outperformed the ASX on capital growth over the past decade. However, when franking credits and dividends are factored in, the total return gap narrows considerably. Past outperformance does not guarantee future results.
How do Australians invest in US stocks?
Australians can access US stocks directly through international brokers like Stake or Interactive Brokers, or through ASX-listed ETFs such as IVV (S&P 500) or NDQ (NASDAQ 100). The ETF route is simpler for beginners as it avoids currency conversion and complex tax reporting.
What is the currency risk of investing in US stocks from Australia?
Currency risk means that movements in the AUD/USD exchange rate affect the value of your US investments when converted back to Australian dollars. A falling AUD boosts your returns; a rising AUD reduces them. Currency-hedged ETFs are available for investors who want to eliminate this variable.
Do US stocks have franking credits?
No. Franking credits are unique to Australian-listed companies and are not available on US or other international stocks. This is one of the key reasons financial planners often recommend maintaining meaningful ASX exposure even for investors who want significant international diversification.
