Investment Diversification: What It Is and How to Do It
Diversification means spreading your money across different investments so that no single company, sector, or country failing can seriously damage your overall portfolio.
Spread Across Assets, Sectors, and Geographies
A diversified portfolio typically mixes asset classes (shares, bonds, sometimes property or cash), sectors (financials, resources, healthcare, technology), and geographies (Australia, the US, global developed and emerging markets) rather than concentrating in one theme. A single low-cost diversified index fund or ETF can achieve broad diversification in one purchase, which is why they're a common starting point for new investors.
Diversification Doesn't Eliminate Risk, It Manages It
Even a well-diversified portfolio will fall in value during a broad market downturn — diversification reduces the risk of any single holding wrecking your results, it doesn't remove market risk entirely. Your time horizon and risk tolerance should still drive how much of your portfolio sits in shares versus lower-volatility assets like term deposits or bonds.
Your Super Fund's Investment Option Is Diversification Too
Many Australians overlook that their default superannuation investment option (often labelled 'Balanced' or 'Growth') is already a diversified portfolio, chosen for them — check your fund's Product Disclosure Statement (available through ASIC's MoneySmart or your fund directly) to see the actual asset allocation, and confirm it still matches your age and risk tolerance rather than assuming the default is automatically right for you.
