Diversification, Growth Opportunities and Global Exposure
International shares can play an important role in building a diversified investment portfolio. They provide access to companies, industries and economies beyond Australia, helping investors spread risk and participate in opportunities that may not exist locally.
For many investors, international shares can complement Australian investments and strengthen long-term portfolio outcomes.
Why Consider International Shares?
The Australian share market is relatively small in a global context and has a strong concentration in financial and resource companies. While Australian shares can provide attractive income opportunities, relying too heavily on local markets can increase exposure to domestic economic conditions and industry-specific risks.
International investing broadens the investment universe by providing access to companies across multiple countries, sectors and economic cycles.
Key Benefits of International Shares
Diversification Across Countries and Industries
Diversification remains one of the strongest arguments for investing globally.
International shares spread investments across different economies, industries and business environments rather than concentrating exposure in a single market.
Global markets provide access to sectors that have limited representation in Australia, including:
- technology and artificial intelligence,
- healthcare and biotechnology,
- global consumer brands,
- advanced manufacturing,
- digital payments, and
- emerging technologies.
Because economies and markets perform differently over time, international exposure can help reduce reliance on the performance of Australia alone and may help smooth returns across changing market conditions.
Access to Global Growth Opportunities
Many of the world’s largest and most innovative businesses operate outside Australia.
International investing allows investors to participate in long-term global trends that can reshape industries and create significant growth opportunities over time.
Global companies continue to drive innovation in areas such as:
- artificial intelligence,
- digital transformation,
- healthcare advances,
- renewable energy, and
- consumer technology.
Investors can gain exposure to businesses and sectors that may benefit from these structural changes over many years.
Reducing Home Bias
Many investors naturally prefer familiar investments close to home. This is often referred to as “home bias”.
However, concentrating too heavily on domestic shares can leave portfolios overly exposed to Australian economic and market conditions.
International investing can help reduce this concentration risk and create a more balanced portfolio across global markets.
Potential for Income and Dividend Growth
Australian investors often value shares for their income potential. While Australian companies may offer attractive dividend yields and franking benefits, some international markets have historically delivered stronger dividend growth over time.
Growing dividends can be particularly important for long-term investors and retirees. If income increases over time, it may help investors keep pace with inflation and rising living costs.
Some overseas companies also pay dividends more frequently, such as quarterly distributions rather than Australia’s more common half-yearly payment pattern. More frequent distributions can support cash flow needs and provide additional compounding opportunities when income is reinvested.
Important Risks and Considerations
International investing offers significant advantages, but investors should also understand the additional risks involved.
Currency Fluctuations
Currency movements can significantly affect returns from international investments.
Even if an overseas investment performs strongly, changes in exchange rates can either increase or reduce returns when converted back into Australian dollars.
For example:
- a weaker Australian dollar may increase overseas investment returns, while
- a stronger Australian dollar may reduce returns.
Some investment managers use currency hedging strategies to reduce the impact of exchange rate movements. While hedging may help smooth returns, it can also introduce additional costs and complexity.
Market and Political Risks
Different countries operate under different economic systems, regulations and political environments.
Global markets can be affected by:
- political instability,
- regulatory changes,
- economic slowdowns,
- geopolitical events, and
- rapid shifts in industry trends.
These factors can create periods of increased market volatility and uncertainty.
Investment Risk Remains
Diversification can help manage investment risk, but it cannot eliminate it entirely.
International shares can rise and fall in value, and past performance does not guarantee future results.
For this reason, international investments should generally be considered as part of a diversified long-term investment strategy rather than in isolation.
Building a Stronger Long-Term Portfolio
International shares can provide valuable diversification, access to global growth opportunities and reduced reliance on the Australian economy alone.
When combined with other asset classes as part of a well-constructed portfolio, global investments can help support long-term wealth creation while managing risk across different market environments.
The challenge is not deciding whether international shares are important, but understanding:
- how much exposure may be appropriate for your circumstances, and
- how international investments fit within your broader financial strategy.
Why Professional Advice Matters
There is no universal formula for determining how much exposure investors should have to international shares.
The appropriate balance depends on factors such as:
- investment goals,
- time horizon,
- income requirements,
- risk tolerance,
- existing investments, and
- tax considerations.
Professional financial advice can help determine an appropriate allocation and construct a portfolio aligned with your broader financial objectives.
Advice may also assist with:
- managing currency exposure,
- maintaining diversification,
- portfolio rebalancing, and
- integrating international investments with superannuation and retirement planning strategies.
