The one-ETF portfolio: is it really enough?

“You’re telling me I should put ALL my money into ONE thing?”

I remember the look on someone’s face when I said it. We were having a conversation about investing, and they’d asked what I’d do if I were starting from scratch. I told them I’d probably buy a single all-in-one ETF and call it a day. They looked at me like I’d suggested they put their life savings on a roulette table.

I get the reaction. It sounds reckless. One fund. Your whole portfolio. Everything riding on a single ticker symbol. But the skepticism comes from a misunderstanding of what that one fund actually contains. Once you look inside, the picture changes completely.

This is not a recommendation to buy any specific fund. I’m sharing what I’ve learned from my own experience, and fund compositions, MERs, and allocations change over time. Always verify current details before making decisions.

What’s inside a single all-in-one ETF?

When people say “one ETF,” they picture one company, one bet, one concentrated risk. The reality is the opposite.

Take XEQT as an example. It holds over 9,000 stocks across more than 40 countries. You’re owning pieces of banks in Canada, tech companies in the U.S., manufacturers in Japan, consumer brands in Europe, and emerging market firms in India and Brazil. All in one purchase.

That’s not one thing. It’s everything, wrapped in one ticker.

Most people I know who pick 8 or 10 individual stocks end up less diversified than someone holding a single all-in-one ETF. They might own five Canadian banks, two tech companies, and a couple of dividend stocks they heard about on a podcast. That’s a concentrated bet on one country and a handful of sectors. The person with “just” XEQT owns thousands of companies across the entire global economy.

Simplicity and diversification aren’t opposites here. They’re the same thing.

In a single all-in-one ETF, simplicity and diversification aren’t opposites. They’re the same thing.

When one ETF is genuinely enough

For a lot of people, a single all-in-one ETF is not a compromise. It’s the right answer.

If you have a long time horizon (10, 20, 30 years), you don’t need to micromanage your holdings. You need broad exposure to global markets and the discipline to keep buying through good years and bad ones. An all-in-one ETF gives you exactly that.

If you’re comfortable with 100% equities, something like XEQT or VEQT covers the equity side completely. If you want some bonds in the mix, balanced versions like XGRO or XBAL hold both stocks and bonds in a single fund, with the rebalancing handled for you.

For people in their 20s, 30s, even 40s, this is a perfectly solid approach. You buy on a regular schedule, you don’t touch it, and you let compounding do what it does. That’s not a simplified version of a real strategy. It is a real strategy. One of the most effective ones available to everyday investors in Canada.

When you might want more

The one-ETF approach isn’t for everyone, and that’s fine.

If you want precise control over your bond allocation, you might prefer holding equity and bond ETFs separately. That lets you adjust the ratio as your life changes without waiting for a fund manager to do it for you.

If you want to tilt toward specific regions or sectors, maybe you think emerging markets are undervalued, or you want more exposure to small-cap stocks, you’ll need to go beyond a single fund.

If you hold investments across multiple account types (TFSA, RRSP, non-registered), there are tax efficiency advantages to placing different assets in different accounts. A single all-in-one ETF in every account doesn’t capture those benefits.

And if you want to own individual stocks for the engagement and learning that comes with it, there’s nothing wrong with that. I hold individual companies myself. The key is knowing what role each part of your portfolio plays. Let the core do the heavy lifting, and keep the individual picks to a size where they won’t derail your plan if one goes sideways.

The complexity trap

Here’s something I see all the time. Someone starts with a simple portfolio, it’s working well, and then they start adding. A sector ETF here. A dividend fund there. A thematic ETF because they read an article about clean energy. Before long, they have 12 holdings and can’t explain what half of them do.

Adding more holdings doesn’t automatically make your portfolio better. Sometimes it just makes it harder to manage. Two funds covering the same market isn’t diversification. It’s duplication. You’re paying two MERs for exposure you already had.

Complexity should be intentional. Every holding should have a clear reason to exist in your portfolio, something it does that your other holdings don’t. If you can’t explain why a fund is there, it probably shouldn’t be.

The best portfolios I’ve seen aren’t the most complicated ones. They’re the ones where the owner understands every piece and can describe the whole thing in a sentence or two.

Is one ETF lazy investing?

I’ve heard people describe the one-ETF approach as “lazy.” I think they’ve got it backwards.

Picking a single globally diversified fund and contributing to it consistently, through market drops, through corrections, through years where nothing exciting happens, requires more discipline than most people realize. The hard part was never picking the fund. The hard part is sticking with it when your coworker is bragging about some stock that doubled, or when the market drops 20% and every instinct tells you to sell.

One ETF isn’t a shortcut. It’s a decision to stop optimizing for the perfect portfolio and start optimizing for the behaviour that actually builds wealth: consistency. Buy regularly. Don’t panic. Give it time.

That’s not lazy investing. That’s disciplined investing. And for most people, it’s more than enough.
