More markets, more asset types, more to keep track of - a broker's view on the modern portfolio

Guest post by Rob Talevski, CEO, Webull Australia

As a broker, I get a good view of how Australians invest, and the shape of a typical portfolio has changed a lot. A decade ago it was a handful of ASX blue chips, bought now and then through one broker and held for years. Today it's just as likely to be a recurring ETF plan, a few US tech names, some crypto and a couple of ASX holdings, across several markets and currencies.

That's a big leap forward in behaviour. Investors can reach more markets, more cheaply and in smaller amounts than ever before. The Australian ETF industry hit a record $372 billion in June 2026, and international equities drew more ETF inflows than any other category in the first half of 2026, according to Betashares.

The trade-off is that a modern portfolio has more moving parts. When holdings span different markets, currencies and asset types, it's easy to lose sight of what you actually own.

I'm not here to tell anyone what to buy or sell, and nothing in this piece is financial advice. But these are the habits I see among investors who manage to stay on top of a modern-day, complex portfolio.

They look at the whole portfolio, not holding by holding

Given the live pricing across these markets, it's natural to focus on individual positions, like the holding that's rallying this week, or the ETF that's lagging. The more useful picture is the overall mix, like how much is in Australia versus overseas, in shares versus crypto, in one sector versus another. Investors who step back and look at that allocation regularly tend to have a clearer sense of the risks they're carrying, and perhaps sleep a little better at night.

They check for overlap

A popular combination is a broad US index ETF, a technology ETF and a few large US tech shares held directly. Each looks different on screen, but they can hold many of the same companies. Investors who look through to the underlying holdings are often surprised by how concentrated a seemingly diversified portfolio can be.

They understand their currency exposure

Owning US shares or unhedged international ETFs means the Australian dollar plays a part in returns. A strong US share price can be offset by a rising Australian dollar, and the reverse is also true. Many international ETFs come in both hedged and unhedged versions, and investors who know which one they hold are better placed to understand why their returns move the way they do.

They know what they're paying

Low brokerage has made regular investing far more accessible, but costs still add up. Brokerage, currency conversion fees and ETF management fees all affect returns, and they compound over time. Investors who read the fee schedule and ETF disclosure documents tend to have a clearer sense of what their portfolio really costs to run.

They review on a schedule, not on a headline

With crypto trading around the clock and share prices updating in real time, it's tempting to react to every move. The investors I see managing well tend to set a regular rhythm instead, such as a quarterly check-in, to look at the whole portfolio calmly and against their own goals and investment rules. This helps avoid allowing emotional decisions to cloud judgement.

They keep their records tidy as they go

Every purchase, dividend reinvestment and crypto swap creates a record. Investors who save statements as they arrive, and export crypto histories regularly, find it far easier to answer basic questions about their portfolio at any point in the year. It also helps at tax time, especially with changes to capital gains tax due to apply from 1 July 2027, which is a conversation worth having with a registered tax agent.

Conclusion

The way Australians invest has moved on quickly, and that's a good thing. More choice brings more to keep track of, and the investors who do best with a modern portfolio tend to be the ones who understand all of it clearly. None of that requires changing how you invest, just a habit of looking at the whole picture.
