The Opportunities & Benefits Of Investing in US Growth Stocks
Investing in US growth stocks can help drive long-term portfolio growth for Australian investors. The US share market often experiences higher gains than the Australian market - in the year to May 2025, Australia’s ASX 200 index returned 7.5% (excluding dividends), compared to almost 16% for the US’ NYSE Composite, and close to 30% for the NASDAQ Composite.
While the Australian sharemarket is heavily weighted towards traditional sectors like banking and resources, the US market offers access to a broader range of global market leaders—from technology and healthcare to consumer goods, consulting, business services and clean energy. US growth companies often outperform the market during periods of economic expansion, as their reinvestment strategies and scalability allow them to capture increasing market share.
The US market is home to headlining large-cap stocks like Meta, Microsoft, Amazon and Netflix, along with an abundance of mid-cap and emerging growth companies that are leaders in niche industries or developing breakthrough innovations. This variety makes the US a fertile ground for identifying the next generation of market leaders, offering Australian investors a chance to strengthen their portfolio with future-focused assets.
So what are the best US growth stocks to buy now? The answer depends upon individual investment goals and portfolio strategy. When evaluating US growth stocks to buy, investors should consider:
- Long-term industry trends - such as ecommerce, digital payments, sustainable energy, artificial intelligence, automation and ageing health needs.
- Diversification - across various sectors, to reduce industry-specific risks.
- Individual stock analysis - using essential metrics such as market capitalisation, earnings growth rates & revenue projections.

Understanding The Risks & Considerations Of US Growth Stocks
With high potential growth comes high potential risk. US growth stocks often attract rapidly increasing stock prices because the market rewards their innovation, growth to date and perceived growth potential. However, economic shifts and changes to predicted future earnings can impact investor sentiment significantly, making returns volatile.
This is especially the case in fast-moving sectors such as technology, biotech and renewable energy. High growth US stocks can experience significant market fluctuations and may take time to generate substantial returns. Before investing, it is important to assess market conditions, company fundamentals, and industry and economic outlooks. Maintaining a longer-term investment time-frame, and building a diverse portfolio, can help mitigate risk.

How To Build A Portfolio With US Growth Stocks
Diversification is the key to building a resilient investment portfolio. If one area of your investments is hit by a downturn, diversification increases the chance that other areas of your portfolio will continue to grow. This is particularly important when investing in US growth stocks, as they can experience sizeable short-term volatility.
Within the class of high growth US stocks, you can diversify across various sectors and across more established versus undervalued, high-potential stocks. At a portfolio level, diversification can occur across geographic regions, and across asset types—including bonds and high dividend-yielding value stocks.

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.

Can recommend them for great service and approaches.
