The Opportunities & Benefits Of Investing In US Tech Stocks
US tech stocks offer investors compelling long-term growth potential. With a focus on innovation, an ability to rapidly scale up, expand globally and establish recurring revenue streams, US tech companies can outperform other sectors.
As the world becomes more digitally connected, demand for transformative technology continues to rise. US tech firms in areas like artificial intelligence, cloud computing, semiconductors and fintech are setting the pace for global markets.
For Australian investors, US tech stocks not only support geographic portfolio diversification, but they also provide exposure to opportunities that are not simply available within the local market. While volatility is a feature of the technology sector, long-term investors stand to reap rewards through careful stock selection and portfolio management.
The US technology sector is dominated by its three biggest players—NVIDIA, Microsoft, and Apple—which make up almost 54% of the total sector market capitalisation, and are core holdings in many investor portfolios.
However, the smaller-cap stocks can also offer exciting growth opportunities, albeit with potentially higher risks. In July 2025, the top 10 growth technology stocks with quarterly earnings and revenue growth in excess of 25% had market caps under US$350b.
The following are just four of the many US tech stocks worth considering for their innovation and strong growth prospects.

- Market capitalisation: ~$4.12 trillion (USD)+
- 12-month revenue: ~$130.5 billion (USD)*

Understanding The Risks & Considerations Of US Tech Stocks
The rapidly changing world of technology offers investors both strong upside potential and unique risks, particularly in fast-moving areas like artificial intelligence, biotechnology and cybersecurity. Business models and industry can be suddenly disrupted, and market sentiment often experiences significant swings.
For established companies, market leadership can be threatened by innovation and the rapid rise of competitors. For emerging players, inflated stock valuations can quickly drop if they struggle to live up to the hype. External forces—such as changing interest rates, regulations and geopolitical factors—also impact US tech stock prices.
To help manage risk, investors should look for sound business fundamentals as well as growth potential, and keep an eye on competitive positioning and broader macroeconomic conditions. Portfolio diversification across big tech, emerging tech, and niche innovators can also help balance over/undervaluation, growth prospects and risk factors.

How To Build A Portfolio With US Tech Stocks
Diversification is the key to risk management when investing in technology. When one stock or segment faces pressure due to demand, regulation or the competitive landscape, other stocks may continue to perform strongly.
Within the technology sector, diversification can be achieved by investing across subsectors—such as cloud infrastructure, software and cybersecurity. Investors can also look to hold stocks across large-cap tech giants, mid-cap innovators and emerging or niche companies.
At a broader portfolio level, balancing US tech stocks against other asset classes such as bonds, defensive or dividend-paying stocks, along with investments in other geographic markets, will also help to withstand market volatility.

We changed broker during the year as we were not getting great results. So glad we joined up with Harry at Sharewise. He has taken the time to genuinely get to know us and discuss our investing strategy. He is always quick to answer a text or phone call. And so far I can say that our portfolio is looking far healthier than it was before the switch.
