Tracks S&P 500

When people talk about 'the US stock market', this is basically what they mean. You own tiny slices of the 500 biggest US companies: Apple, Microsoft, Nvidia, Google, Amazon. Around a quarter of your money goes to the top 10 names alone, so the fund leans heavily into US tech.

Tax notes for non-US investors

Both CSPX and VUAGare Irish-domiciled UCITS ETFs, so dividends from their US holdings are taxed at 15% under Ireland's US treaty, rather than the 30% that applies to US-domiciled funds for many non-US investors, and they sit outside US estate tax. Your own local tax still depends on where you live, so check your country's rules; for most investors the main ongoing cost to watch is each fund's annual fee.
