What is CNDX?
Without the jargon.
What it owns, how it differs from CSPX, and how hard its falls have been.
Evidence snapshot:
One fund. The Nasdaq 100.
CNDX is a Nasdaq 100 index fund. It is the London-listed, US-dollar trading line of the iShares NASDAQ 100 UCITS ETF.
It aims to track the Nasdaq 100: 100 of the largest companies listed on the Nasdaq stock exchange.
It leaves out banks and other financial companies. Many of the rest are technology companies.
Is CNDX accumulating?
Yes. Dividends the fund receives, after costs and taxes, are reinvested inside it.
Does CNDX pay dividends?
Not in cash. The reinvested dividends show up in the price of your units instead.

CNDX vs CSPX: what is different?
Both are Irish, accumulating iShares funds, listed in London in US dollars. The difference is what they hold.
| CNDX | CSPX | |
|---|---|---|
| Follows | Nasdaq 100 | S&P 500 |
| Companies | About 100 | About 500 |
| Banks and insurers | Left out | Included |
| Annual fund charge | 0.30% | 0.07% |
| US$10,000 became | About US$172,600 | About US$87,100 |
| Growth a year, compounded | 19.5% | 14.5% |
| Worst month-end fall | -33.5%, Dec 2021 to Dec 2022 | -22.5%, Dec 2021 to Sep 2022 |
How we got these: month-end London closing prices in US dollars, the same Yahoo prices our index calculator uses. Trading costs, currency changes and tax are not included. Falls between month-ends can be deeper.
CNDX overlaps a lot with CSPX. So it is not a separate safety net. It is a bigger bet on the same large technology companies.
Its better record since 2010 came while big technology companies did very well. That may not repeat.
The Nasdaq 100 has fallen much further.
CNDX only started in 2010. QQQ, a US fund that follows the same index, goes back to 1999.
QQQ's fall from March 2000 to September 2002, at month-end prices with dividends reinvested.
It did not get back to its March 2000 level until October 2014, more than 14 years later.
Since 1999, the worst fall for SPY, an S&P 500 fund, was 51%, from October 2007 to February 2009.

How buying CNDX works
The steps are the same as for CSPX. Search for CNDX or ISIN IE00B53SZB19. Check the full name, the accumulating share class and the US-dollar London listing.
Select the ETF itself, not a CFD or another leveraged product.
One unit cost about US$1,770 on 9 October 2026. You need the full price unless your broker sells fractions of a unit.
Broker fees and currency charges can cost more than the fund fee, especially on small orders. See the costs to check. Under 18? Start here with a parent.
Why Ireland matters here too
Like CSPX, CNDX is based in Ireland. US dividends received by an Irish fund generally face 15% US withholding.
A US fund is different. If your country has no US tax treaty, as in Singapore, the US generally keeps 30% of its dividends. Read how Irish funds are taxed.
Common questions about CNDX
Is CNDX the same as QQQ?
No. Both follow the Nasdaq 100. QQQ is based in the US and pays its dividends out in cash. CNDX is based in Ireland and reinvests them.
Is CNDX riskier than CSPX?
It holds fewer companies and leans heavily on technology, so its falls have been bigger. From its December 2021 peak, its worst month-end fall was 33.5%, against 22.5% for CSPX.
Can I buy CNDX from Singapore?
It is available through brokers offering the London listing, subject to their account eligibility and product-access rules. Check your broker directly and verify the ISIN before ordering.
