Are factor ETFs fit for purpose?

As you try to navigate the market shift consider whether factor funds are serving their purpose
Are factor ETFs fit for purpose?
  • Investment styles have been increasingly important in recent years but targeting them via funds can be complicated
  • Momentum funds have done well in recent years but some have lagged in the recent rally
  • Sector funds may be a better way to play a value upswing than value funds

The cyclical rally of the past half year may have reignited the debate about value stocks, but it has also had a knock-on effect on other investment styles. Having already fed into associate editor Algy Hall’s blue-chip momentum stock screen, a value tilt in momentum strategies has now become evident among funds such as iShares Edge MSCI USA Momentum Factor UCITS ETF (IUMF).

This exchange traded fund’s (ETF) recent half-yearly rebalancing has seen it tilt heavily away from growth stalwarts towards cyclical names. Microsoft (US:MSFT), Amazon (US:AMZN) and Apple (US:AAPL) have all exited the fund, having been among its top 10 holdings before the rebalance. The fund’s allocation to financials, meanwhile, has jumped from just 1.5 per cent of its assets before the rebalancing to 32.5 per cent. And its allocation to information technology stocks has fallen from 41.1 per cent to 17.7 per cent.

The half-yearly rebalancing means that iShares Edge MSCI USA Momentum Factor UCITS ETF should be positioned to capture any further gains from cyclicals, although it appears to have missed some of the big earlier returns. So as you try to navigate the shift in markets you need to consider whether factor funds are serving their purpose. While targeting certain factors can deliver outperformance, executing this effectively via funds can be difficult.

To test this, we have looked at how some popular factor ETFs have performed in different market conditions. For the sake of consistency, we have focused on a range of factor funds offered by iShares.

 

Momentum: strong gains but slow to the party?

Recent years have been kind to many momentum funds, which back the market’s winners and sell the losers. iShares Edge MSCI World Momentum Factor UCITS ETF (IWFM) strongly outperformed conventional MSCI World trackers in the five years to 2 June 2021, with iShares Edge MSCI Europe Momentum Factor UCITS ETF (IEFM) clearly beating an MSCI Europe ex-UK tracker over the same period.

iShares Edge MSCI World Momentum Factor UCITS ETF has beaten its conventional equivalent in five out of six full calendar years since its launch. iShares Edge MSCI Europe Momentum Factor UCITS ETF has done the same in three out of four full calendar years since its launch. And iShares Edge MSCI USA Momentum Factor UCITS ETF has beaten an MSCI USA tracker in three out of four full calendar years of its existence.

Yet, as we noted in Style Wars (IC, 08.01.21), this approach also stakes a great deal on the continued success of the market’s leaders, something that can sometimes be detrimental to the returns of a fund which doesn't rebalance frequently.

Until its rebalance, iShares Edge MSCI USA Momentum Factor UCITS ETF had big stakes in names such as Tesla (US:TSLA) and the FAANGs – Facebook (US:FB), Amazon, Apple, Netflix (US:NFLX) and Alphabet (US:GOOGL). But it had little in cyclicals, explaining its underperformance during the cyclical rebound that followed news of the Pfizer vaccine. Between 9 November 2020 and 3 June 2021, iShares Edge MSCI USA Momentum Factor UCITS ETF made a total return of 5.3 per cent. As the chart shows, this puts it behind both conventional market trackers and value funds.

Further disappointments may still be due. If the cyclical rally continues, iShares Edge MSCI USA Momentum Factor UCITS ETF may well capture some of this. But if most of the cyclical rally has already taken place and growth stalwarts such as the FAANGs are due a rebound, a momentum fund may miss the biggest gains from this.

 

Value funds: capturing the upswing

Value has finally enjoyed another rebound, and factor ETFs have certainly caught some of this upside. But investors should question whether value funds are the best route to gains in a sector. The same thinking can apply to the likes of quality funds, where more direct exposures may deliver bigger gains.

Matt Brennan, head of passive portfolios at broker AJ Bell, tends to favour sector ETFs over factor funds for two reasons. Sector funds tend to be cheaper than factor ETFs and, perhaps more importantly, he views sector funds as a more direct play on an investment style.

“They often give you a better exposure to the factor, as the factor-based ETFs are sector neutral in lots of cases and therefore are only tilted [to] rather than full-out value," he says. "By using a banks, energy, and travel and leisure ETF, you are going to get a deeper exposure to the value factor without having to allocate as much and pay as much."

This focus on sector neutrality can be seen in iShares Edge MSCI USA Value Factor UCITS ETF (IUVF). As of early June, its biggest sector weighting was a 26.8 per cent allocation to information technology. Financials made up just 11.7 per cent of the fund, and energy a mere 2.7 per cent.

Sector funds have been the most obvious winners of the cyclical rally since November. The best performer in the Investment Association North America sector between 9 November and 3 June was iShares S&P 500 Energy Sector UCITS ETF (IESU), which made a total return of nearly 60 per cent. Active funds with a focus on sectors such as energy and financials have also posted big gains.

It should be noted that sector funds with a narrower focus can also make bigger losses in difficult times. iShares S&P 500 Energy Sector UCITS ETF lost 22.5 per cent in the three years to 3 June compared with a 27.8 per cent gain for iShares Edge MSCI USA Value Factor UCITS ETF.

Fans of investment styles should also remember that active funds may fare better when their style is out of favour. Several active US equity funds with 'value' in the name have outperformed iShares Edge MSCI USA Value Factor UCITS ETF over three years, for example.

 

Minimum volatility: worth the drag?

There is a mixed case for minimum volatility funds. Performance data from 20 February to 27 March 2020, a period that captures the brunt of the initial pandemic sell-off, shows that the iShares minimum volatility products suffered smaller falls than conventional indices – especially the emerging market and global products. But, as the chart shows, they have also notably lagged conventional trackers and other factor ETFs in the cyclical rally. iShares Edge MSCI World Minimum Volatility UCITS ETF (MINV) returned just 1.8 per cent, compared with an 11.6 per cent gain for the conventional MSCI World tracker.

While investors may want a smoother ride, the performance of these products demonstrates that easing off risk can limit your returns both in good times and the longer run.
