Frequently asked questions
Is CSPX.L accumulating or distributing?
iShares Core S&P 500 UCITS ETF (CSPX.L) is an accumulating ETF, so its dividends are reinvested automatically inside the fund instead of paid out as cash. The value compounds in the share price, which keeps things simple since the dividends are reinvested for you instead of arriving as cash you would otherwise have to reinvest yourself.
What is the annual fee (TER) for CSPX.L?
CSPX.L has a total expense ratio (TER) of 0.07% per year. On a $10,000 holding that is roughly $7 a year, charged inside the fund rather than billed to you separately. A lower fee leaves more of the return compounding for you over time.
Can I buy CSPX.L on Interactive Brokers?
Yes. CSPX.L trades on LSE, USD and is available to investors worldwide through Interactive Brokers (IBKR). IBKR is the most popular way to buy UCITS ETFs because of its low FX conversion cost (around 0.03%) and low trading commissions.
What does CSPX.L invest in?
iShares Core S&P 500 UCITS ETF (CSPX.L) tracks the S&P 500. When people talk about 'the US stock market', this is basically what they mean. You buy one fund and get the whole basket in a single trade.
Is CSPX.L a UCITS ETF, and where is it domiciled?
Yes, CSPX.L is a UCITS ETF domiciled in Ireland. For non-US investors, Irish-domiciled UCITS ETFs are usually preferred over US-domiciled ones: US dividend withholding tax is 15% under the tax treaty (versus 30% on US-domiciled funds for many non-US investors), and the holdings sit outside US estate tax.
How risky is CSPX.L?
On the TickerCompare 1 to 5 scale, CSPX.L is rated medium risk (3/5), based on how much its price has moved historically. Higher-risk funds can fall further in a downturn, so match the choice to your time horizon and how much volatility you can stomach.
