Back in 2007, Warren Buffett made a bet that a group of hedge fund managers wouldn't be able to beat a passive S&P 500 index fund over a period of 10 years.
The real question here is whether it's actually possible for stock pickers to beat the market after deducting fees.
Buffett (and the S&P 500) famously won the challenge in 2017, but years on, the debate over whether active funds or passive (index) funds are the better investment shows no sign of abating.
So we thought we'd put it to the test ourselves by comparing the performance of Australia's passive index fund ETFs with actively managed ETFs, as covered recently by the AFR's Wealth Generation newsletter:
As part of the test, we analysed different timeframes including both bull market and bear market periods.
How do index funds compare to active funds over the last 5 years?
Over the past 5 years, our group of ASX-listed index funds returned 6.79% p.a. on average, net of fees.
These funds outperformed our group of active funds, which saw an average return of 5.09% p.a., also net of fees.
Even when narrowing down to the last 3 years and the previous 12 months (to 30 September 2023), passive funds continue to lead with returns of 9.3% and 15.97% against 8.25% and 13.6% for active funds, respectively.
At the top of the passive ETFs, the Betashares Nasdaq 100 ETF (NDQ), an ETF that tracks the tech-heavy Nasdaq 100 index, returned 16.92% p.a.
Compare this to the worst index fund performer, the iShares China Large-Cap ETF (IZZ), which saw negative returns of -5.42% p.a. over the 5 years.
Meanwhile the top-performing active ETF, the WCM Quality Global Growth Fund (WCMQ), returned 9.73%, compared to the worst performer at -1.66% p.a. (K2 Australian Small Cap Fund, KSM).
Can active funds beat passive funds in a bear market?
A common argument (made mostly by active fund managers) is that active strategies become most relevant during periods of economic uncertainty.
To test this theory, we looked at the performance of both active and passive ETFs during the 2 most recent bear and bull markets. Previous periods, such as the 2008 GFC, were excluded as very few ASX ETFs were listed at the time.
A bear market is when the stock market has fallen 20% or more from its peak, while a bull market is the same but in reverse.
Our findings showed actively managed funds actually performed slightly worse during market downturns.
During the short bear market between February and March 2020, ASX passive funds fell by 29% on average, closely followed by actively managed funds which fell by 29.37%.
Notably, specific funds like the ASX 200 index fund (IOZ) plunged by 35.59%, while the S&P 500 index fund (IVV) fell by 23%. On average, both passive and active funds showed nearly parallel performance.
The bear market of 2022 painted a slightly different picture. ASX passive funds saw a decline of 15.99%, while actively managed funds experienced a steeper drop of 17.78%.
The bottom line?
Aussie investors can rest assured that low-fee index fund investing in Australia can and does work, regardless of the volatilities of the market.
Our data suggests passive index funds in Australia tend to perform better on average than active funds and this mostly appears to be the case regardless of market conditions and length of time.
These results highlight just how difficult it is for even the most experienced stock pickers to beat the market, especially when fees are taken into account.
This doesn't mean passive index funds are the best choice for everyone or that all active funds underperform. When picking an ETF it's important to take your personal circumstances and financial goals into account. If in doubt, speak to a professional.
What was our methodology?
We used ASX categorisations to create 2 groups of passive and actively managed ETFs. We then excluded ETFs with the following features:
Publicly listed for less than 5 years
Synthetic ETFs
Bond and cash ETFs
Commodity funds (e.g. funds that track the price of a single commodity)
Inverse ETFs
We were left with 100 passive index funds and 24 managed funds.
