Are you asking the right questions about your ETFs?

Wednesday brought a split session on the ASX. Technology pushed higher while energy pulled back, and the gap between the two sectors was wide enough to matter for most diversified portfolios. A good day to check what you actually own, not just what you think you own.

A question worth sitting with

A lot of people who are just starting out spend weeks comparing ETFs, reading every product disclosure statement, and agonising over which one is marginally better. That energy is understandable. But there is a quieter risk sitting underneath all that searching: not knowing what the ETFs you already hold actually contain. Two funds with different names and different price tags can hold almost identical baskets of companies. If you have never looked inside your funds side by side, you might be taking on more concentration than you realise, without any deliberate choice to do so.

So here is the question worth sitting with today: before you think about adding something new to your portfolio, when did you last look at what your current holdings actually own at the company level?

What moved today

Information Technology was the standout, up 4.52% for the session. COH climbed 4.70%, a strong individual move that reflected broader enthusiasm in the sector. Materials also had a decent day, rising 2.42%, with KAR gaining 3.64%. Real Estate and Industrials both moved modestly higher as well.

Energy was the clear underperformer, falling 2.99%. WDS added 2.77% against that sector trend, which is a reminder that sector averages can mask meaningful variation within them. PLS dropped 4.94% and NEM fell 2.92%, two names sitting at opposite ends of the materials and energy story today. As always, single-session moves tell you what happened, not why it matters for the long run.

A lesson worth keeping

If you have ever looked at a handful of your ETFs and noticed the same company names appearing across most of them, you have encountered overlap. It is one of the quieter risks in a multi-fund portfolio. You might feel diversified because you hold six different products, but if four of them are drawing from the same pool of large-cap companies, your actual spread is narrower than the number of funds suggests.

The fix is not necessarily to sell anything. It starts with awareness. Listing the top ten holdings of each fund you own, then counting how often the same names appear, takes about twenty minutes and usually tells you something useful. Diversification is about what you own underneath, not how many funds sit on the surface.
