The multi-faceted nature of equity factor investing means it can play a dynamic and highly useful role in portfolios, especially for investors looking for a diversified exposure that can perform in the long run.
Investment performance of quantitative factor-based strategies has been varied recently for a number of reasons.
Our experience with sector neutral value investing has been positive. Our models saw good performance from 2000 until mid-2018, with a blip in 2009. However, despite the fact that we choose to control for sectors, value stocks did poorly in 2019/2020. Indeed, irrespective of whether we use the price-to-book ratio as a value factor, all value factors did poorly in late 2019 and in 2020. Only now, in 2021, have value factors started performing well again.
It is important to recognise that the value style seeks to benefit from cheap stocks converging to their fundamental values; for expensive stocks, that entails that performance has to be poorer for valuations to converge with those of cheaper stocks. That did not happen in 2019 and 2020, causing value spreads to widen to levels last seen in 2000 tech bubble.
Given the premise of value investing, we are facing a favourable period for value stocks because it’s more likely that we will see value spread compression than further spread expansion. This new trend may have started already with the strong performances of value stocks so far in 2021.
2020 was also the year when the low-volatility premium was not there. A low beta in bullish markets makes it difficult for low-vol stocks to do well. The outperformance of mega caps also did help since owning those would most likely have meant a large underweight in low-vol stocks.
This is also showing signs of changing in 2021. However, as the markets remain positive and strong, low-volatility stocks are still just about delivering market performance.
We believe that the performance of value and low risk (volatility), as well as quality and momentum, in well-diversified multi-factor strategies should be assessed over the long run.
Adding in an ESG perspective to such balanced portfolios does not detract from their ability to perform, especially when it comes to quality and low risk, which tend to fit well with a sustainability-based approach. We find it natural that ESG is aligned with the type of factor exposures we have in our quant equity multi-factor approaches.

Investing in emerging markets, or specialised or restricted sectors is likely to be subject to a higher-than-average volatility due to a high degree of concentration, greater uncertainty because less information is available, there is less liquidity or due to greater sensitivity to changes in market conditions (social, political and economic conditions).
Some emerging markets offer less security than the majority of international developed markets. For this reason, services for portfolio transactions, liquidation and conservation on behalf of funds invested in emerging markets may carry greater risk.
