Learn More ASX investors aiming to capitalise on market volatility may wish to invest in the United States. One way this can be achieved is through ASX ETFs. The past few months have proven especially volatile for US equity markets. In February, Chinese start-up company, Deepseek, arrived on the scene, wreaking havoc in the technology sector. Chipmaker Nvidia (NASDAQ: NVDA) saw its share price decline nearly 20% in one day. Markets took another dramatic turn as US President Donald Trump announced his reciprocal tariffs on 'Liberation Day'. Since then, there has been significant volatility. The Trump administration has reportedly entered discussions with several nations, including Japan, the European Union and China, to reach trade deals. While these developments have boosted market sentiment, major US indices are still materially lower than they were at the start of the year. For the year to date, the S&P 500 is down 10%, while the Nasdaq Composite Index has fallen nearly 16%. Retail investors have been buying in the dip at record numbers. Among the most popular trades are US technology shares and global exchange-traded funds (ETFS), according to the Australian Financial Review. Those looking for US-focused ASX ETFS are spoilt for choice, with several options available. ASX investors can tailor their selection depending on their outlook and preferred level of diversification. Here are five to consider. Vanguard US Total Market Shares Index AUD ETF (ASX: VTS) Vanguard US Total Market Shares Index AUD ETF is one of the most popular ETFs on the ASX. It is extremely diversified across the entire US market, with 3,598 holdings. That means it includes the likes of Nvidia (NASDAQ: NVDA) and Microsoft (NASDAQ: MSFT), as well as a range of microcap companies. It is especially low cost, with a management fee of 0.03%. Investors wanting to bet on the strength of the overall US economy may prefer this ETF. iShares S&P 500 AUD ETF (ASX: IVV) Alternatively, those looking to invest in the largest and most well-known companies only may wish to invest in iShares S&P 500 AUD ETF. This ETF tracks the S&P 500 Index, which contains the 500 largest listed companies in America. With a management fee of 0.03%, it is also very low-cost. Betashares Nasdaq 100 ETF (ASX: NDQ) ASX investors bullish on the US technology sector may be more interested in the BetaShares Nasdaq 100 ETF. For a management expense of 0.48%, this ETF tracks the technology-heavy Nasdaq Composite, which comprises 100 of the largest non-financial companies. Global X Fang+ ETF (ASX: FANG) Investors who believe the largest US technology stocks will outperform the market from here may be interested in the Global X Fang+ ETF.
