Active vs Passive Investing: What the Evidence Actually Says

What is active investing?🔗

Active investing means trying to beat the market return, either by picking individual stocks yourself or by paying an actively managed fund whose manager selects holdings and tilts the portfolio. The goal is alpha: returns above what the market delivers on its own. Managers charge for this, and not lightly: active Australian equity funds typically run 0.70% to 2%+ a year, sometimes with a performance fee on top. The question is whether the alpha covers the cost. Usually, it does not.

What is passive investing?🔗

Passive investing means tracking an index rather than trying to beat it: you buy the whole market (or a broad slice) via an index fund or ETF and accept the market return minus a tiny fee. Familiar examples are VAS (ASX 300), VGS (global developed markets), and all-in-one funds like VDHG and DHHF. Typical passive ETF fees are 0.04% to 0.20% a year. You are not betting on which companies win; you own all of them, and the index rebalances automatically. One distinction to clear up: active vs passive is not the same as ETF vs managed fund. Active ETFs and index managed funds both exist; the real axis is whether a fund tries to beat or match the market, and what it costs.

What does the evidence say?🔗

The SPIVA Australia Scorecard, published by S&P Dow Jones Indices, is the gold standard for measuring active performance against benchmarks, and it accounts for survivorship bias (failed funds that quietly close). The year-end 2024 results are stark.

Over 10 to 15 years, roughly 87% of active Australian equity managers underperform the ASX 200, and about 85% of global equity managers trail their benchmark. This is not just bad luck. As Nobel laureate William Sharpe pointed out, in aggregate all investors earn the market return, so active investors as a group must earn the market return before costs, and less than it after their higher fees. That is arithmetic, not opinion. The less-efficient corners (small caps, emerging markets) are the exception, where skilled managers fare better.

Why passive tends to win🔗

Three drivers. First, fees, which compound viciously: on $100,000 over 30 years at an 8% gross return, an active fund at 1.5% grows to roughly $661,000 while a passive fund at 0.2% reaches about $951,000, a gap of around $290,000 lost to fees alone. Our fee drag calculator lets you run your own numbers.

Second, tax: active funds trade more, so higher turnover triggers more capital gains distributions (taxable even if you did not sell), whereas index funds rarely trade and are more tax-efficient. Franking credits flow through both, so no edge there. Third, behaviour: passive is boring by design, which makes it easier to hold through downturns, while active tempts performance-chasing and market timing, the two biggest return-killers.

The honest case for active🔗

We are not here to strawman it. Some managers do outperform; the problem is picking them in advance, since past performance is a weak predictor. Active can genuinely add value in less-efficient markets (small caps, emerging markets), can offer downside protection through defensive mandates (which you pay for, and which lag in bull markets), and can access strategies an index cannot easily capture (infrastructure, private assets). And there is nothing wrong with DIY stock picking as a hobby and learning tool, provided you keep it to a small slice and do not confuse a bull market with skill.

It is not binary: core and satellite🔗

Most experienced investors use both. The core-and-satellite approach puts 80% to 90% in a low-cost passive core (VAS, VGS, or an all-in-one like VDHG or DHHF) and keeps a 10% to 20% satellite for active positions, individual stocks or thematic bets. You get the benefits of passive (low cost, diversification, tax efficiency) while leaving room to express a view without betting the whole portfolio.

Which is right for you?🔗

For most people the answer to "should I pick stocks or index?" is clear: start with the index. Add active positions only when you have a concrete reason, not because you feel you should be doing something. Passive for the core, active only at the edges.
