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.
See full CSPX details →This invests in 400 medium-sized US companies that sit just below the household-name giants. These firms are often still growing and can behave differently from the large-cap market. It fills the gap between big-company and small-company funds.
See full SPY4 details →Both CSPX and SPY4are 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.

Frequently asked questions
Which is cheaper, CSPX.L or SPY4.L?
CSPX.L is cheaper. CSPX.L charges 0.07% per year and SPY4.L charges 0.30%. Both are inexpensive index funds, but a lower fee compounds in your favour over the long run.
Are CSPX.L and SPY4.L accumulating or distributing?
CSPX.L is accumulating, so dividends are reinvested automatically inside the fund. SPY4.L is accumulating, so dividends are reinvested automatically inside the fund. Accumulating funds suit investors who want hands-off compounding with no cash dividends to reinvest manually.
Are CSPX.L and SPY4.L both UCITS ETFs?
Yes, both are UCITS ETFs (CSPX.L domiciled in Ireland, SPY4.L in Ireland), so both give non-US investors the 15% US dividend withholding rate and sit outside US estate tax, unlike US-domiciled ETFs.
