iShares Global Clean Energy Transition UCITS ETF

You get the dividends as cash you can spend or move elsewhere, which some people like for a sense of income. If you would rather it compounded, you buy more units yourself — it will not reinvest on its own the way an accumulating version does. The same fund is often sold in both versions; what it holds underneath is identical.

Owning every holding keeps things transparent — what is in the index is what the fund actually owns. It can be a touch costlier to run for indexes with thousands of tiny positions, since the fund has to buy and maintain them all. There is no swap bank involved, so there is no extra “what if the partner fails” question to weigh.

For example, a 0.20% fee works out at €0.20 a year for every €100 invested — that’s a generic illustration of the mechanic, not this fund’s own fee. It is skimmed quietly from inside the fund a little each day, so you never get a bill — but it drags on your return every year you hold. On a broad index ETF it is usually a small fraction of a percent; the gap between a cheap and a pricey fund looks tiny on day one but compounds over decades, which is why it is worth a glance.
