Active vs passive investing: what the data says and what it misses

The active vs. passive investing debate has been going on for decades, and both sides have strong opinions. If you spend time in Canadian personal finance circles, you’ll mostly hear the passive side: buy index funds, keep costs low, don’t try to beat the market. That’s solid advice. But it’s not the whole picture.

I invest mostly passively. Most of my portfolio sits in low-cost index funds. But I also hold individual stocks, companies I’ve researched and believe in. I don’t think that makes me inconsistent. I think it makes me honest about what keeps me engaged as an investor.

This isn’t financial advice. I’m sharing what I’ve learned from my own experience and what the data shows. Your situation is different from mine, and what works for one person might not work for another.

What “active” and “passive” actually mean

The terms get thrown around a lot, so it’s worth being precise.

Passive investing means buying a fund that tracks an index. The fund doesn’t try to pick winners or avoid losers. It just holds everything in the index, in proportion to each company’s size. If you buy an S&P 500 index fund, you own a slice of all 500 companies. The fund manager’s job isn’t to make decisions. It’s to match the index as closely as possible, for as little cost as possible.

Active investing means someone is making decisions about what to buy and sell, and when. That someone could be a professional fund manager running a mutual fund, or it could be you picking stocks in your own brokerage account. The goal is usually to outperform a benchmark, whether that’s the TSX, the S&P 500, or some other index.

The distinction matters because it determines what you’re paying for. With passive, you’re paying for access to the market. With active, you’re paying for someone’s judgment. And judgment has a price tag.

What the data says

This is where it gets uncomfortable for the active side. The SPIVA scorecard, published by S&P Global, tracks how actively managed funds perform against their benchmarks over time. The Canadian numbers are consistent with what you see globally.

Over a 10-year period, roughly 80 to 90 percent of actively managed Canadian equity funds underperform the S&P/TSX Composite Index after fees. The numbers vary slightly depending on the exact time period, but the direction never changes. The longer the time horizon, the worse active management looks in aggregate.

That’s a striking number. If you picked an active Canadian equity fund at random a decade ago, you had somewhere around a one-in-ten chance of it actually beating the index. And that’s before considering survivorship bias, because the funds that performed the worst often get quietly merged or closed, which makes the survivors look better than the full picture.

But here’s the part that gets lost in the headlines: “most” doesn’t mean “all.” Some active managers do outperform, and some do it consistently. The problem is identifying them in advance. The fund that beat the index over the last five years might not beat it over the next five. Past performance, as the disclaimers always say, really doesn’t guarantee future results.

The cost gap

This is where passive investing has its clearest advantage.

A typical actively managed Canadian equity mutual fund charges a management expense ratio (MER) of 1.5% to 2.5%. Some are higher. That’s the annual fee you pay regardless of whether the fund goes up or down.

A broad Canadian index ETF like XIC charges about 0.06%. An all-in-one global ETF like XEQT or VEQT charges about 0.20%. Even at the higher end, you’re paying a fraction of what active funds cost.

The difference between 0.20% and 2.00% might not sound like much. It’s 1.8 percentage points. But over decades, that gap compounds into something enormous. On a $100,000 portfolio growing at 7% annually, a 2% fee eats roughly $170,000 over 30 years compared to a 0.20% fee. That’s not a rounding error. That’s a house. Or a retirement that starts five years earlier.

This is the active manager’s real challenge. They don’t just need to beat the index. They need to beat it by enough to cover their higher fees and still come out ahead. And the data says the vast majority of them can’t do that over the long run.

The honest case for active investing

If the data so clearly favours passive, why does anyone invest actively? There are a few reasons, and not all of them are irrational.

Some people enjoy it. Researching companies, reading earnings reports, understanding industries. For some investors, this is genuinely engaging. It’s not just about the returns. It’s about the process. If stock picking keeps you interested in your finances and learning about how businesses work, that has real value. The alternative for some people isn’t “passively invest and relax.” It’s “get bored and stop paying attention entirely.”

Skin in the game changes behaviour. When you own shares of a company you actually chose, you pay attention differently. I bought Shopify years ago because I was working in e-commerce and kept seeing the smartest companies move to their platform. That kind of pattern recognition doesn’t show up in a stock screener. I walk past a Dollarama and think “I’m a shareholder of that.” That engagement has made me a better investor overall, even in the passive part of my portfolio.

Not all markets are equally efficient. The S&P 500 is one of the most analyzed, most traded markets in the world. Beating it consistently is extremely hard because so many smart people are trying to do the same thing. But smaller markets, niche sectors, or less-followed companies might have more room for skilled investors to find undervalued opportunities. The research on this is mixed, but the idea isn’t crazy.

Some active strategies serve specific goals. If you need income in retirement, or you want to tilt toward certain sectors for reasons specific to your situation, a purely passive approach might not fit perfectly. Active decisions, even small ones, can help tailor a portfolio to individual needs.

The honest case for passive investing

The passive side is straightforward, and the arguments are strong.

Lower cost. This is the biggest one. Every dollar you don’t pay in fees is a dollar that compounds in your favour. Over a career of investing, the fee savings alone can be worth hundreds of thousands of dollars.

Less time. A passive investor using an all-in-one ETF might spend 20 minutes a month on their investments. Buy on a regular schedule, rebalancing happens automatically, done. That time is worth something.

Historically better results for most people. The SPIVA data isn’t ambiguous. Most people who try to beat the market, whether through picking stocks themselves or choosing active fund managers, end up with less money than if they’d just bought the index. That includes professionals with research teams and Bloomberg terminals.

It removes emotional decision-making. In March 2020, I watched Canadian bank stocks fall 15% in a single day and Air Canada drop 40%. The NYSE hit circuit breakers. If I’d had to make active decisions about every position in a moment like that, I might have flinched. The passive core of my portfolio needed no decisions. I just kept contributing. That automatic behaviour protects you from the panic selling that destroys returns for so many investors. Staying invested through the rough stretches is half the battle, and passive makes it easier.

The middle ground: core and satellite

Here’s what I actually do, and what a lot of experienced investors end up doing. It’s sometimes called the core-satellite approach.

The core of my portfolio is passive. Low-cost, globally diversified index funds. This is where the majority of my money sits, and it’s where I expect the majority of my long-term returns to come from. I don’t think about it much. I contribute regularly and let it compound.

The satellite is a smaller allocation to individual stocks. Companies I’ve researched, businesses I understand and believe in. This is the part that keeps me engaged. I enjoy following these companies. I learn from owning them. And yes, sometimes they outperform the index, and sometimes they don’t.

The key is that the core does the heavy lifting. If every individual stock I own went to zero tomorrow (unlikely, but hypothetically), my financial plan would still be intact because the foundation is solid. The satellite is money I can afford to be wrong about.

This isn’t the only valid approach. Plenty of people are perfectly happy with 100% passive, and the data supports that choice. But if you’re someone who wants to be more involved, the core-satellite structure lets you do that without putting your entire portfolio at risk.

Canadian-specific options

If you’re investing in Canada, here are the building blocks most people work with.

For passive Canadian equity exposure, XIC (iShares) tracks the S&P/TSX Composite for an MER of about 0.06%. XIU (iShares) tracks the TSX 60, the largest 60 companies, for about 0.18%. Both give you broad Canadian market exposure at very low cost.

For passive U.S. equity exposure, VFV (Vanguard) and ZSP (BMO) both track the S&P 500 in Canadian dollars. MERs around 0.09%.

For a one-fund solution, XEQT (iShares) and VEQT (Vanguard) are all-in-one global equity ETFs that hold thousands of companies across Canada, the U.S., international, and emerging markets. MERs around 0.20%. This guide covers them in detail. If you want some bonds mixed in, XGRO and VGRO offer an 80/20 stock-to-bond split.

For individual stocks, any Canadian discount brokerage lets you buy shares of companies on the TSX and most U.S. exchanges. Commission-free trading is increasingly common.

The point is that the tools for both approaches are readily available and cheap. The question isn’t access. It’s which approach fits how you want to invest.

What actually matters

The active vs. passive debate generates a lot of heat, but the variables that matter most aren’t really about this choice at all. They’re about whether you’re investing consistently, whether you’re keeping costs reasonable, whether you’re diversified enough, and whether you can stay invested through downturns without panicking.

A passive investor who panics and sells everything during a crash will do worse than an active investor who stays calm and holds through it. A stock picker who does deep research and holds long-term will likely do better than someone who chases whatever’s trending on social media. The label matters less than the behaviour.

Whether you invest actively or passively matters less than whether you invest consistently and stay the course.

If you’re starting out, passive is almost certainly the right foundation. Buy a broad, low-cost index fund, contribute regularly, and give it time. If you’ve been investing for a while and you want to add some individual positions alongside your core holdings, that can work too. Just be honest about why you’re doing it and make sure the foundation stays solid.
