What does iShares Core FTSE 100 UCITS ETF (Acc) do?

The iShares Core FTSE 100 UCITS ETF tracks the performance of the FTSE 100 index, meaning a single purchase spreads your money across massive household names like HSBC, AstraZeneca, and Shell. Instead of trying to pick individual winners, you own a basket of the biggest businesses trading on the London market. The ongoing charge is just 0.07% a year, which works out to about seventy pence annually for every thousand pounds you hold. It is an accumulating fund, so any cash dividends paid out by the companies are automatically rolled back into the fund to grab more shares for you.

What it tracks

Holds the 100 largest companies listed in London and automatically reinvests the dividends.

OCF: Ongoing Charge Figure: the fund's yearly running cost, taken automatically. 0.22% is about £2.20 a year for every £1,000 you hold.
0.07%
≈ £0.70 a year per £1,000 invested
Yield: The income the fund has paid out over the past year as a percentage of its price. Accumulating funds reinvest this for you instead of paying cash.
