The Rise of Big Tech: Why Global Diversification Still Matters

Technology companies have been a major driving force behind global sharemarket returns in recent years. Household names such as Apple, Microsoft, Nvidia, Amazon and Alphabet have grown into some of the world's largest businesses, with artificial intelligence (AI) creating further excitement about their future potential. For investors, this growth creates opportunity — but also increases the importance of understanding how much of a portfolio is exposed to a small group of companies.

Many Australians gain exposure to US technology companies through their superannuation and some may be surprised by much of their portfolio is concentrated in a handful of large US companies.

This concentration can be beneficial when these businesses perform strongly. However, it also means investment portfolios may be more vulnerable if technology valuations fall, earnings disappoint or enthusiasm surrounding AI begins to fade.

Why diversification still matters

Diversification isn't simply about owning lots of different investments. It's about spreading exposure across industries, countries, investment styles and asset classes.

While US technology companies remain important contributors to global economic growth, other opportunities exist across healthcare, financial services, industrials, infrastructure and emerging markets.

Keeping a balanced perspective

Rather than trying to predict which companies or industries will outperform next, investors should consider whether their portfolios are appropriately diversified.

The key isn't necessarily to avoid US technology companies, but to ensure their influence within your portfolio remains appropriate.
