The short version
Three questions matter more than a fund name
First, what does the ETF actually own? Second, what role would it play beside the investments you already have? Third, what are you paying for and what trade-off comes with it? A good answer to those questions is more useful than a long shortlist.
01 · Start with the exposure
An ETF name is a label, not the full answer
Two ETFs can sound similar while tracking different indices, holding different numbers of companies or putting very different weights on the largest businesses. “Global”, “quality”, “income” or “technology” tells you where to start looking. It does not tell you the whole exposure.
What to check: the index or strategy, the largest holdings, the main countries and sectors, and whether the fund is broad or deliberately focused.
02 · Then look at the portfolio you already have
More ETFs can still mean more of the same
Holding several funds can feel diversified. But broad global, US and technology ETFs may all include many of the same large companies. The second or third ETF should have a clear job to do; otherwise it may add complexity without changing your exposure very much.
What to check: whether a new ETF adds a distinct exposure or mostly repeats companies, countries and sectors you already own.
03 · Cost is important, but it is not the whole decision
The lowest TER is not automatically the better ETF
The annual fund charge matters. So do the spread when you trade, platform charges, the way the ETF tracks its index and the structure you are choosing. A lower price is useful only if you are still comparing funds that do the job you actually want done.
What to check: total costs in context, the fund’s structure and the specific exposure you receive for those costs.
A practical next step
Keep your first comparison simple
- Choose two ETFs that appear to solve the same problem.
- Compare what each one tracks, its costs and how it treats income.
- Read the factsheet before deciding whether either has a place in your portfolio.
