Is it worth investing?
iShares Core S&P 500 UCITS for broad US stock market exposure
$822.67 +26.17% over 12 months Last updated: 2026-10-01
iShares Core S&P 500 UCITS aims to mirror the S&P 500 index, a basket of around 500 large US listed companies from sectors such as technology, healthcare, consumer and financials. The fund is denominated in US dollars, while investors buy and sell units on LSE, so currency movements between the dollar and an investor’s home currency can affect the final result. By design it focuses only on the US market and does not include shares from other regions or smaller company segments.
The ETF is managed by BlackRock Asset Management Ireland - ETF and has been available since 19 May 2010, operating as a UCITS fund that trades on the exchange like a single share. It is typically used by investors who want to build the US equity part of a diversified portfolio, either as a long term core holding or as an additional allocation alongside global funds. IE00B5BMR087 is the ISIN code that uniquely identifies this ETF in trading systems and official documentation.
Key data
Return and risk

- Last 12 monthsWhat the fund returned over one year, from one date to the same date a year earlier.

- 5 years, per yearThe yearly average over the last five years, not their sum.
- 10 years, per yearThe yearly average over the last ten years, not their sum.
- Compounded over 10 yearsHow much a sum left in the fund would have grown over the whole period, with the yearly figure above compounding year after year. Past returns guarantee nothing.

- Return / risk, 3 yearsHow much return the fund produced for each unit of swing. Higher is better.
- In the 52-week rangeWhere today's price sits between the past year's low and high. 0% is at the low, 100% at the high.
Some values update after the trading session opens, others are recalculated after it closes.
Cost and size
- Annual costWhat the fund keeps each year out of your money to run itself. It is taken out of the value, not billed separately.
- Assets under managementWhat everything the fund holds is worth. A large fund is harder to close and usually easier to buy and sell.
- Portfolio turnoverHow much of what the fund holds is replaced in a year. The higher it is, the more trading costs pile up.
- Launched inThe year the fund started operating.
- DomicileThe country where the fund is registered. It matters for the tax withheld on the dividends the fund receives.
- ISINThe fund’s international code. Use it at your broker so you do not confuse it with another line of the same fund.
Some values update after the trading session opens, others are recalculated after it closes.
What the fund holds
- SharesHow much of the fund is in shares. The rest can be bonds or cash.
- Top sector: TechnologyThe area that weighs most in the fund. The heavier it is, the more the fund depends on it.
- Top region: North AmericaThe part of the world where most of the fund's money ends up.
- Top ten holdingsHow much the ten biggest holdings weigh together. The more they weigh, the fewer companies the fund hangs on.
- Effective holdingsHow many equally weighted companies would give the same spread. It is smaller than the real count, because some weigh far more than others.
- Companies heldHow many companies the fund holds in total.
- Very large companiesHow much of the fund sits in the largest companies on the market. A lot means steadier prices, but also less room to grow.
- CashThe part held in money rather than shares. In an index fund it is small and shifts from one day to the next.

Which index iShares Core S&P 500 UCITS tracks
The fund does not pick companies itself. It copies a ready-made list, and that list has a name.
The index copied by iShares Core S&P 500 UCITS
The index has no page here yet, but this is its name: you can look it up anywhere.
SS&P 500GSPC.INDX
An index fund does not try to beat the market, it tries to follow it closely. Its return looks like the index return, less the annual fee. The small gap between the two is called tracking difference.
Pros and cons
What speaks for this fund, and what speaks against it.
For7 arguments
- It has grown well over the long run.Over the last 10 years it returned 15.2% a year, which compounds to 311%. How it has gone so far says nothing about what comes next.
- It was positive over every period measured.26.2% over one year, 21.8% a year over three, 13.5% a year over five. Not a guarantee, but not one lucky year either.
- The annual cost is low.The fund keeps 0.07% a year, below the 0.20% mark at which an index fund counts as cheap. The difference compounds year after year.
- The fund is large and well established.It manages $146.69B. A fund this size is unlikely to be closed and is usually easy to buy and sell.
- It has a long track record.It has been running for 16 years, so it has already been through several downturns, not just one good stretch.
- It holds cheaper companies than the category average.The price asks 21.95 times the expected profit of the companies in the fund, against 22.74 times for the category average.
- It swings little for an equity fund.Volatility over the past year was 13.1%, below the usual mark for equity funds.
Against3 arguments
- The last year ran well above its average.Over twelve months it returned 26.2%, while the five-year average is 13.5% a year. Anyone looking only at the last year will expect too much.
- It leans heavily on a single sector.The largest sector, Technology, makes up 39.9% of the fund, against 34.5% for the category average. When that area falls, the fund falls with it.
- Almost all of it sits in one region.North America takes 99.6% of the fund. That means one currency and one economy, taken as a package.

What you would have earned
The returns actually achieved, taken out of percentages and put into money.
What you would have earned by investing in iShares Core S&P 500 UCITS
$1,000 put into the fund 10 years ago would have reached $4,113, at a return of 15.19% a year. Type your own amount and everything recalculates.

These figures have already happened. They are not an estimate for what comes next, and a period starting in another year gives another result. The amounts are before tax and before your broker’s fee, while the fund’s own fee is already taken out of them.
Fees and costs
The same percentages as above, counted in money. That is where their weight shows.
The annual fee of iShares Core S&P 500 UCITS (TER)
The fee is 0.07% a year (TER). A small percentage a year, added up over years, stops being small.
0.07%
10 yrs20 yrs30 yrs
- after 10 years$128
- after 20 years$503
- after 30 years$1,480
Over 30 years that comes to 2.2% of everything you would have gained. Worked out on $10,000 and an assumed return of 7% a year: the return is an assumption, the fee is not, it is taken whichever way the market goes.
Risk and volatility
An equity fund goes up and down. Here is how far, at the worst that has been measured.

These days are not a sign that the fund is broken: every equity fund has them. What counts is how often they come and how deep they go.
Valuation and growth
Not the fund, but the companies in it: what they cost and how fast they grow, against the category average.
How dearly the companies in the fund are valued
The percentage on the right of each row shows how far above or below the category average it sits. Dearer does not mean worse, and cheaper does not mean better.

Who it suits
Four ways of using a fund. The ticks say what each one looks for and what it finds here, not what is good and what is bad.
A first fund to hold
Someone starting out who wants one fund, broad and cheap.
3 of 5
- The annual cost is low
- The money is well spread
- It does not hang on one sector
- The fund is large
- It has a long record
Money in the account
Someone who wants to receive something, not only watch the price rise.
0 of 3
- The fund pays dividends
- It pays at least four times a year
- The yield clears 1.5% a year
A bet on one sector or region
Someone who already holds a broad fund and wants to add a specific exposure.
2 of 3
- Nearly all of it is in one region
- It hangs heavily on one sector
- The top ten weigh a lot
Held without watching it
Someone paying in monthly who does not want to check the price every week.
2 of 4
- It swings little, for equities
- It has had no very deep fall
- It rarely changes what it holds
- It has been through several bad spells
The ticks are worked out from the fund’s own figures, with the same thresholds used everywhere on this page. They do not say whether the fund is good, but whether it looks like what each profile is after. A fund that ticks nothing for one profile may be exactly right for another.
