Do I have too much US tech in my portfolio?
Probably more than you think. A lot of portfolios that look diversified are actually heavily exposed to US tech — just spread across different funds.
Why this happens
The biggest companies in the world today are mostly US technology firms. Because of that, they dominate global stock market indices. So when you buy a global ETF, an S&P 500 tracker, or a tech-focused fund, you're often buying into the same core group of companies again and again — Apple, Microsoft, Nvidia, Amazon, Alphabet and Meta.
How concentration quietly builds
This usually isn't intentional. You might start with a global ETF, then add a tech fund or a few individual stocks. Each decision makes sense on its own, but together they can leave 40–60% or more of your portfolio tied to the same sector and region.
Is that actually a problem?
Not necessarily — US tech has performed extremely well. But it does mean you're relying heavily on one area of the market. If that sector underperforms, it can affect almost everything you own at the same time. The real issue is unintended exposure.
A simple way to sense-check it
- How much is invested in the US overall?
- How much sits in technology companies?
- Do the same names appear across multiple funds?
Key takeaway: US tech concentration often hides in plain sight across multiple seemingly different investments.
