Index fund vs. mutual fund? In this article, we look at the differences between index funds and mutual funds and help you decide on which to choose.
Investment experts and academics have long debated the merits of index fund vs mutual fund. The difference comes down to two things: methodology and cost. Most mutual funds are actively managed, which means a fund manager makes decisions as to which stocks to buy and sell, and when to buy and sell them. The goal of a mutual fund is to beat a particular benchmark. In contrast, an index fund passively tracks a benchmark (like the S&P 500), without a manager making any active decisions. Active funds charge more than passive funds because they have to pay the manager, researchers, mutual fund dealers, plus an army of fund salespeople. Index funds don’t have that type of overhead and so they charge a fraction of the cost of an actively managed fund.

Canadian investors have nearly $2 trillion invested in mutual funds, most of which are actively managed. But a good portion of these mutual funds charge some of the highest fees in the world. Research from Morningstar clearly shows that, absent of a crystal ball, fees are the best predictor of future returns. As in, the lower the fees, the higher the return. Let’s explore the differences between index funds and mutual funds to explain why.

Do Index Funds Outperform Mutual Funds?

The rise of actively managed mutual funds began in the 1990s, when interest rates started to fall, and Canadian investors sought higher returns. Mutual funds enabled all types of investors, large and small, to access markets at a low cost, with no commissions to buy and sell funds. Active managers provide professional portfolio management, diversification, and opportunities for investors to access both foreign and domestic markets.

Active management is often touted as a way for investors to outperform the market thanks to superior investment strategy and insights from the fund manager and research team. Another perceived benefit is the ability of active managers to “avoid” market corrections by making real-time decisions to buy or sell securities and help protect investors’ downside.

In reality, most active managers fail to outperform their benchmark index over the long term. Their ability to avoid market downturns is also overstated. According to the SPIVA Scorecard, more than 88% of Canadian Equity active managers underperformed the S&P/TSX Composite over the 10-year period ending in June 2019.

Simply put: it’s hard to pick winning stocks. It’s hard to time the market. And it’s impossible to identify the best active managers ahead of time – you can only look backwards to see how each manager performed.

Passive investing only become popular in the last 10 years, and Canadian investors still lag behind other countries in the global shift from active to passive strategies. Passive investing makes up just 10% of the market in Canada, whereas nearly half the funds invested in the United States are passively held.

Index funds typically charge a fraction of the cost of their actively managed counterparts. That’s because index funds use a rules-based methodology to passively track their benchmark index. They don’t rely on an active manager to make judgement calls on which stocks and bonds to hold, and when to buy and sell them. With no fund manager or researchers to pay, those savings get passed down to the investor through lower fees.

Investment Objectives

Investors who embrace passive investing through index funds are following the belief (backed by empirical and academic research) that building a low-cost globally diversified portfolio that simply tracks the market leads to the best investor outcomes over the long term.

The theory behind avoiding active management is that high fees and bad individual behaviour lead to poor performance. Instead, buy index funds and investors will achieve market returns, minus a small fee.

Proponents of active management through mutual funds don’t believe in settling for “average” returns. They strive to outperform the index through superior stock picking and market timing skills. It sounds great in theory, but in reality, the vast majority of actively managed mutual funds fail to beat their benchmark index after fees.

The late Jack Bogle, Vanguard founder and father of index investing said:

“What happens in the fund business is that the magic of compounding returns is overwhelmed by the tyranny of compounding costs. It’s a mathematical fact.”

The Deal Breaker is the Cost 

It doesn’t take a genius to know that a mutual fund that has to pay managers, researchers, marketers, and salespeople will cost more than a bare-bones index fund that simply represents an index. These costs are passed down to investors through the management expense ratio (MER).

An actively managed mutual fund might charge 2.25% MER. Here’s how those costs break down:

  • Administration charges (overhead): 0.25%
  • Fund manager fees (including profit): 1.00%
  • Trailing commission (split between advisor and firm): 1.00%
  • Total: 2.25%

Investors pay more to own actively managed mutual funds in hopes to outperform the market, yet all evidence shows that high costs all but guarantee an active mutual fund will underperform its benchmark.

Many investors simply misunderstand how much a 2% fee really is. It’s not 2% of 100%. It’s 2% in the same context as earning a 6% return on your investment. Take away 2% in fees and you’re left with just 4% in investment returns. Don’t make the mistake of thinking a couple of percentage points don’t matter – in the long run, they’re huge.

Index funds charge fees, too, but much much less than mutual funds. That’s because index funds typically do nothing more than track broad market benchmarks like the S&P 500. In our example in the chart above, we made two hypothetical investments – one in an index fund and another in an actively managed mutual fund. Both funds earned 7% per year (before fees) for 30 years. The index fund cost 1.62% less than the actively managed fund and its “investor” ended up more than $231,000 richer.
