Ep 405: How to construct an ETF portfolio

Read Full Blog Here

There are two sensible ways to invest in ETFs: use a diversified, all-in-one fund, or build your own portfolio. Both can work. The difference comes down to control, scale, and behaviour.

In this episode, Stuart explains why simple diversified ETFs are often the right starting point, particularly for smaller balances or investors who value simplicity and discipline. But as portfolios grow, constructing your own ETF portfolio can offer meaningful advantages, particularly around valuation, diversification, and tax efficiency.

The core principle is straightforward: quality first, then price.

Stuart introduces the “Forever Test," a simple filter to identify index exposures you would be comfortable holding for decades, not just for the next cycle. From there, the focus shifts to valuation, and why the price you pay remains one of the most important drivers of long-term returns.

The episode also breaks down where returns actually come from income, earnings growth, and repricing, and how a value-aware approach to ETF selection can improve outcomes across all three.

You’ll also learn the four key ways to tilt a portfolio: geography, index methodology, company size, and emerging markets, and how these levers can be used to build a more considered and flexible portfolio without abandoning diversification.

At its core, this is not about complexity. It is about improving the odds. Because the real edge is not just what you invest in but how you structure it, and whether you can hold it long enough for compounding to do its work.
