NDQ vs VGS: Diversifying, or Doubling Down on US Tech?

🔍 The overlap nobody mentions🔗

VGS weights its holdings by company size. The largest companies in the developed world are American technology firms, so they sit at the top of VGS. NDQ tracks the hundred largest non-financial companies on the Nasdaq, which are, again, largely American technology firms.

Same names, different wrapper. Buying NDQ alongside VGS is closer to ordering a second helping than to ordering a different dish.

🎯 The essential: Two tickers is not the same as two exposures. What matters is what sits underneath them, and here a great deal of it is the same handful of companies.

🏛️ What the Nasdaq-100 actually is🔗

It is worth being precise, because the name suggests something broader than it is. The Nasdaq-100 is not the American share market. It is the 100 largest non-financial companies listed on one exchange.

Three consequences follow, and all three are by design:

• No banks, insurers or asset managers. Financials are excluded by the index rules, not by accident. Betashares says so on its own product page.
• Nothing listed on the NYSE. Many of the largest American companies are, so they are simply absent.
• Nothing outside the United States. No Japan, no Europe, no Australia.

NDQ listed in May 2015 and had around $8.93 billion in net assets in September 2026. It pays semi-annually and yielded 1.5% over the previous twelve months.

🌍 What VGS gives you🔗

VGS tracks MSCI World ex-Australia and holds 1,314 securities across developed markets. It charges 0.18%, had about $17.58 billion in net assets, listed in November 2014, and yielded 1.29% over the previous twelve months.

Crucially, it excludes no sector. It holds the banks, the miners, the healthcare companies and the consumer staples businesses alongside the tech firms, in whatever proportion the market happens to give them. It makes no call about which sector should win.

💸 The fee gap is the real cost🔗

This is where the comparison bites, and it is a much wider gap than the ones between core ETFs.

That does not make NDQ a bad fund. It makes it an expensive way to express a view, and the view had better be deliberate.

⚠️ What concentration risk means here🔗

Concentration risk is an abstract phrase until you ask what actually goes wrong at the same time. Here, both funds are exposed to the same events: rising interest rates hitting growth company valuations, antitrust action against the largest platforms, a disappointing result from one or two mega-caps, or a new competitor unseating an incumbent.

When your two funds share their biggest risks, holding two funds does not protect you the way two genuinely different holdings would. Compare that with adding an Australian shares fund, which brings banks, miners and a different currency, or an emerging markets fund, which brings economies with entirely different growth drivers. Those change your risk profile. NDQ mostly intensifies it.

⚖️ Holding both, done deliberately🔗

None of this is an argument against owning NDQ. It is an argument for knowing what you own. If you hold a diversified core and you want a slice tilted towards American technology because you have a view and a time horizon to match, NDQ is a clean way to do that.

The practical check is simple. Look at your actual country and sector exposure rather than your list of tickers. Most brokers will show you the breakdown, and both issuers publish factsheets. If the amount of US tech surprises you, that is worth knowing before the next downturn tells you.
