Why Asset Allocation ETFs Aren’t Just for Beginners Anymore
This article is sponsored by BMO ETFs.
For years, “all in one” or asset allocation ETFs were seen as an ideal entry point for new Canadian do it yourself (DIY) investors: simple, diversified, and low cost. But the landscape has changed. The same characteristics that made these products appealing to beginners are increasingly proving valuable for seasoned investors as well. With markets more complex and globally interconnected than ever, the case for choosing one well structured ETF over building and maintaining a portfolio of multiple holdings is stronger than it’s ever been.
Today, asset allocation ETFs have become a go to solution not only for beginners, but for long term investors of all experience levels. Their simplicity, efficiency, and disciplined structure offer advantages that many Canadians underestimate, even after years of investing.
The Foundation: Whatís Inside An Asset Allocation ETF
At their core, asset allocation ETFs bundle several underlying ETFs into a single, diversified investment. Each underlying ETF targets a specific slice of the global market. While the exact mix- which can range from 100% equities down to 40% equities and 60% fixed income- depends on each investor’s risk profile, investment goals and time horizon, most Canadian all in one ETFs include exposure to:
- Canadian equities
- U.S. equities
- International developed equities
- Emerging markets
- Investment-grade fixed income grade fixed income
In other words, with one investment trade, an investor gains access to a globally diversified portfolio that would normally require multiple trades and ongoing portfolio maintenance.
This structure appeals to beginners, of course—but the same simplicity solves real world challenges for experienced investors too.
Why More Experienced Investors Are Embracing Them
1. A Drastically Simpler Way To Invest
Building and maintaining a diversified portfolio used to mean holding several ETFs—sometimes seven or more. Each position required periodic review, thoughtful rebalancing, and occasional tweaking. For many investors, this added friction led either to mistakes or to procrastination.
Asset allocation ETFs eliminate that complexity. A single trade secures instant global diversification, eliminating the need to choose between individual equity and fixed income ETFs or to weigh the merits of regional allocations. This simplicity is not a concession—it's a feature that removes decision fatigue and supports long term discipline.
2. Automated Rebalancing Keeps Risk Aligned
Markets move unevenly. U.S. stocks may surge ahead while emerging markets struggle. Bonds may spike or slump depending on interest rate expectations. Over time, this pulls a DIY investor’s portfolio out of alignment with its original risk target.
Traditionally, investors had to rebalance manually, selling portions of overweight holdings and topping up underweight positions. This process not only consumes time, but also introduces human error, from spreadsheet miscalculations to emotional hesitation during volatile periods.
Asset allocation ETFs solve this by rebalancing automatically within the fund. Investors stay aligned with their intended risk profile without lifting a finger. This automated discipline is one of the biggest reasons experienced investors are gravitating toward all in one solutions.
3. Simpler Cash-Flow Management in Retirement Flow Management In Retirement
Decumulation—turning a nest egg into spendable cash—can be surprisingly complicated for retirees holding multiple ETFs. Selling proportionate amounts of different funds to raise cash while maintaining the target asset mix takes planning and precision.
With an asset allocation ETF, retirees simply sell the number of units they need. The underlying allocation remains intact, and the portfolio stays diversified. Coupled with the liquidity advantages of ETFs, this makes managing retirement income far easier than juggling multiple holdings.
4. Reduction Of “Tinkering Risk”
Even experienced investors fall into the trap of tinkering—tweaking allocations based on headlines, market fears, or a compelling narrative. This form of speculation can quietly undermine long term results.
For example, in periods when U.S. equities hit all time highs, many investors find themselves overweight in U.S. stocks. The temptation is strong: should they trim their position? Ride the momentum? Hedge their exposure? These decisions introduce stress and often lead to emotionally driven trades.
With an asset allocation ETF, the temptation to tinker largely disappears. The allocation is fixed according to the fund’s mandate. Investors buy, hold, and avoid the psychological noise that leads many DIY investors astray.
The Fee Question
Historically, one of the biggest arguments against all in one ETFs was cost. Investors could theoretically save money by purchasing the underlying ETFs individually, resulting in a slightly lower aggregate management expense ratio.
But fee compression has reshaped this conversation.
With recent management fee cuts for most of BMO’s asset allocation ETFs to 0.15%1, the difference between building your own portfolio and holding a single ETF has become minimal. For most Canadians, the few basis points saved through DIY construction no longer justify:
- the time commitment
- the complexity of managing multiple holdings
- the risk of errors, miscalculations, or emotional rebalancing decisions
- the potential tax slips and wash trade considerations that can arise from juggling several ETFs trade considerations that can arise from juggling several ETFs
While there are still niche cases where building from scratch may offer slight tax advantages or customization benefits, the drain on time and attention often outweighs the incremental savings.
After a Decade Of Observations…
After more than ten years educating listeners, friends, and family about on index investing, I’ve noticed a recurring pattern: while many investors believe they want maximum optimization, what they might actually need is maximum sustainability.
The investors who build multi ETF portfolios start strong, but over time, many struggle with the upkeep, or may misidentify a shifting risk profile of the portfolio. Life gets busy. Rebalancing gets delayed. Market noise creeps in. Small deviations compound into bigger ones.
Meanwhile, those who choose a single asset allocation ETF tend to stay the course. They remain diversified. They avoid tinkering. They follow through on their long term strategy.
Even for investors who understand markets well and enjoy the process, the simplicity of all in one ETFs removes friction from the parts of investing that can quietly chip away at performance: mistakes, emotions, and inconsistency.
The Bottom Line
Asset allocation ETFs are no longer just beginner friendly training wheels for DIY investors. They have matured into powerful, efficient, and highly disciplined tools that serve a wide spectrum of investors.
For most Canadians—especially those who value long term results over constant portfolio maintenance—the convenience, diversification, automatic rebalancing, liquidity, and now ultra competitive fees can make all in one ETFs not only a smart starting point, but an excellent destination.
Whether you’re just beginning your investing journey or several decades in, the question is no longer “Are asset allocation ETFs good enough?”
It’s increasingly becoming:
“Why complicate your portfolio when a single, low cost, globally diversified ETF can do the hard work for you?”
