With value spreads now at levels last seen at the peak of the tech bubble in 2000 , we expect spreads to narrow in the coming years. That bodes well for value and multi-factor equity strategies irrespectively of their level of sophistication.
In Value investors: is this their biggest opportunity since the Tech Bubble?, we looked at how spreads have changed for stocks in the MSCI World, US and Europe indices and in different global macro sectors. We found that at the end of 2020, spreads across the board had risen to levels last seen at the peak of the tech bubble.
With such a large dispersion, the risk of spread compression is now high. What can we expect in periods of spread compression for common factor styles and their multi-factor combinations?
In table 1-A, we show the performance of the value, quality, momentum and low risk factor styles for stocks in the MSCI World index based on similar robust macro-sector neutral and beta-neutral long-short factor strategies.
We have included an equal risk contribution multi-factor composite based on the aggregation of the four styles. For illustration purposes, we have added a low-size factor, also based on a macro-sector neutral and beta-neutral strategy.
In table 1-B, we repeated the exercise while relying on more traditional approaches to construct the factor portfolios.

Factors in Table 1-A are macro-sector and beta-neutral and based on a target volatility approach with each style based on a diversified set of factors. Factors in Table 1-B are neither sector nor beta-neutral, and each style depends on one single raw factor. Source: Bloomberg, FactSet, Worldscope, IBES, Exshare-ICE, BNP Paribas Asset Management. For illustration purposes only.
For the more robust sector and beta neutral factor styles, the performance of value has been significantly better in periods of value compression and less good in periods of value spread expansion.
The same has been the case for smaller capitalisation stocks, perhaps even more so: The size factor only seems to be positive in periods of value spread compression. Quality, momentum and low volatility, appear to be less sensitive to changes in value spreads.
For the simpler raw factor styles, the differences in factor performance have been more pronounced as a function of the regime of changes in value spread: Value and size factors have outperformed only in periods of value spread compression and clearly underperformed in periods of value spread expansion.
In turn, quality, momentum and low volatility factor styles have done well when value spreads expanded and less well when value spreads compressed.
Multi-factor strategies tend to do particularly well in periods of value spread compression. They can also do well in periods of value spread expansion, in particular when based on the more robust sector and beta-neutral factor styles, but still do less well than in spread compression periods.
It is interesting to notice that investing in the best single raw factor with a perfect foresight timing strategy based on the value spread would have barely outperformed the more diversified multi-factor composites.
The recent poor performance of value stocks, smaller-cap stocks and multi-factor strategies can be understood in light of the expansion of value spreads.
With value spreads now at 20-year plus highs and with a compression of spreads on the cards, we believe that the coming years are likely to be particularly favourable for value stocks, small caps and multi-factor strategies.
 Value stocks are typically cheap relative to their fundamental values, while glamour stocks are highly priced, creating gaps in valuations known as value spreads. Also see Value investing: Is this the biggest opportunity since the tech bubble?

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.
