Stocks with a lower market value (mid and small caps) have endured particularly strong headwinds recently. For instance, the MSCI World Small Cap Index underperformed the MSCI World Index by 7.5% in March and by 9% over the first quarter of the year. As a result, factor strategies with a tilt towards small cap stocks, including most of Robeco’s equity factor portfolios and indices, also experienced painful times.
To illustrate this, Figure 1 plots the performance of several generic factor strategies built using both a market-cap-weighing scheme and an equal-weighting scheme. Equal weighted strategies give the same weight to each component of the portfolio, thereby giving a lower weight to large cap stocks and a higher weight to small and mid-cap stocks, relative to their market-cap-weighed counterparts.
Many empirical studies have shown that equity factors, such as value, momentum, quality, and low volatility, have historically delivered substantially higher performance in the small-cap than in the large-cap segment of the market.1 This is true not just for theoretical portfolios ignoring implementation hurdles, but also when trading costs and other market frictions, which tend to be higher for small-cap stocks, are taken into account.
Small-cap factor strategies simply deliver more exposure to the underlying equity factors
However, Robeco’s in-house research2 also shows that differences in factor exposures between the small-cap and the large-cap factor portfolios fully explain the differences in the subsequently realized returns. Put differently, we have seen that while factor premiums are not rewarded more in the small-cap segment of the market, small-cap factor strategies simply deliver more exposure to the underlying equity factors.
This means that although small-cap stocks in general may not intrinsically be particularly attractive simply because of their low market-capitalization, this segment of the equity market offers attractive investment opportunity potential from a factor perspective. Investors should therefore consider a bottom-up induced tilt towards attractive smaller stocks. We believe this approach will allow investors to get the breadth needed to unlock the full potential of factor strategies.3
Of course, a size tilt will inevitably make the performance more vulnerable to a broad temporary bout of underperformance of small-cap stocks, relative to their larger counterparts. The recent poor performance of small and mid-cap-tilted factor strategies is a case in point. Because small cap stocks tend to move in a correlated fashion, factor strategies with a tilt towards small cap stocks will also tend to feature slightly higher volatility than their market-cap weighted counterparts.
However, we believe these apparently offsetting characteristics should not deter disciplined long-term investors. For one, the generally higher volatility and sensitivity of these portfolios to the short-term relative performance of small and mid-cap stocks should be considered as the price to pay for the long-term added value provided by the increased breadth – leading to higher factor exposures – of small-cap tilted factor strategies.
While small and mid-cap stocks tend to be hit hardier during corrections, they also tend to rebound faster in the following period
Moreover, the historical performance of the small-cap stocks versus large cap stocks, during economic recessions and subsequent recoveries, shows that while small and mid-cap stocks tend to be hit hardier during corrections, they also tend to rebound faster in the following period (see Figure 2). In fact, our research shows that factor strategies that allow a tilt towards smaller stocks tend to achieve higher long-term information ratios than their market-cap weighted counterparts.
For investors, the upshot is that they need to make sure they understand the implicit risks that come with each strategy and only accept those that are properly rewarded. This is why Robeco dedicates significant research resources to disentangling rewarded from unrewarded risks, to ensure that our clients are only exposed to the segments of the market that are rewarded in the long run. And we think that small and mid-cap stocks with attractive factor characteristics are one of them.
