Diversification is an investment strategy that involves spreading investments across various asset classes, sectors, or geographical regions to reduce risk and enhance potential returns. By not putting all your financial resources into a single investment or type of investment, you mitigate the impact of poor performance from any one investment on your overall portfolio.

Importance of diversification

Risk reduction

Diversification helps reduce the risk associated with individual investments. If one investment performs poorly, others in the portfolio may perform well, balancing the overall return.


A diversified portfolio is generally more stable because it includes a mix of investments with varying risk levels and performance characteristics. This balance can lead to more consistent returns over time.

Maximising returns

By investing in a variety of assets, you can take advantage of different market conditions. Some investments may perform well in certain economic environments, while others may do better in different conditions.

Capital preservation

Diversification helps protect your capital by spreading the risk across multiple investments. This approach reduces the likelihood of significant losses from any single investment.

Types of diversification

Asset class diversification

This involves spreading investments across different asset classes such as stocks, bonds, real estate, and commodities. Each asset class has its own risk and return characteristics, helping to balance the overall portfolio.

Sector diversification

Investing in different sectors of the economy, such as technology, healthcare, finance, and consumer goods, helps reduce sector-specific risks. Economic and market conditions affect sectors differently, so diversification can provide a buffer against sector downturns.

Geographical diversification

By investing in different geographical regions, you can reduce the impact of regional economic downturns. International investments can provide exposure to growth opportunities in emerging markets and hedge against domestic market risks.

Investment style diversification

This strategy involves diversifying across different investment styles, such as growth, value, income, and momentum investing. Each style has unique characteristics and performs differently under varying market conditions.

Time diversification

Investing at different times, rather than all at once, can help mitigate the risk of market timing. This approach, known as dollar-cost averaging, involves investing a fixed amount regularly, regardless of market conditions.

How to implement diversification

Assess your risk tolerance

Understanding your risk tolerance is crucial for building a diversified portfolio that aligns with your financial goals and comfort level with risk.

Choose a mix of asset classes

Select a variety of asset classes to create a balanced portfolio. The proportion of each asset class will depend on your risk tolerance and investment objectives.

Select diverse investments within each asset class

Within each asset class, choose investments from different sectors, regions, and styles to further spread the risk.

Regularly review and rebalance

Periodically review your portfolio to ensure it remains diversified and aligned with your investment goals. Rebalancing involves adjusting your portfolio by buying or selling investments to maintain your desired asset allocation.

Use investment funds

Mutual funds, exchange-traded funds (ETFs), and index funds offer built-in diversification by pooling money from multiple investors to buy a broad range of securities.


Consider an investor with a diversified portfolio that includes:

  • Stocks: 40% invested in Australian companies across various sectors, 20% in international companies.
  • Bonds: 20% in Australian government and corporate bonds.
  • Real estate: 10% in real estate investment trusts (REITs).
  • Commodities: 10% in gold and other commodities.

If the Australian stock market experiences a downturn, the international stocks, bonds, real estate, and commodities can help offset the losses, leading to a more stable overall portfolio performance.
