Another added benefit of this sometimes-forgotten segment is diversification. Mid caps tend to be less impacted by currency fluctuations and global downturns than large caps, which often include major corporations and multinationals that operate around the world.
Investors also tend to be underallocated to mid caps. Based on overall market capitalization, we might expect funds to allocate three times as much to large caps compared to mid caps. However, investment in large-cap mutual funds and ETFs is about seven times more than that of their mid-cap peers.4 Market observers have lamented that US large caps have become even more concentrated, as they are dominated now by mega tech holdings.
At the end of 2022, technology sector holdings comprised 24% of the Russell 1000 Index, including 13.4% of the top 10 holdings in the index.5 Meanwhile, tech sector holdings in the Russell Midcap Index made up just half that at 12%, with tech representing just 1.5% of its top 10.6
Beyond the market-cap criteria, we believe that multifactor strategies can potentially deliver enhanced diversification with higher risk-adjusted returns and lower volatility than traditional market cap-based indexing. In our view, a forward-looking, rules-based index design that analyzes individual stock exposure against a well-vetted blend of factors—quality, value, momentum and low volatility—helps provide exposure to high-quality companies at a reasonable price while avoiding value traps.

The S&P Pure Value Index includes only those components of S&P MidCap 400 that exhibit strong value characteristics, and weights them by value score. The S&P MidCap 400 Low Volatility Index measures the performance of the 80 least-volatile stocks in the S&P MidCap 400. The S&P MidCap 400 Quality Index is designed to track high quality stocks in the S&P MidCap 400 by quality score, which is calculated based on return on equity, accruals ratio and financial leverage ratio. The S&P MidCap 400 Momentum Index is designed to measure the performance of securities in the S&P MidCap 400 universe that exhibit persistence in their relative performance.
As shown in the table above, the value factor—which emphasizes inexpensive stocks relative to their fundamentals—performed better than the broader market last year, with the S&P MidCap 400 Pure Value Index returning -3.6% against the S&P MidCap 400 Index, which was down about -13% for the year.7 By comparison, momentum stocks, which tend to show ongoing positive price trends, underperformed the most in 2022. Quality-tilted stocks, marked by profitable companies with capital efficiency and low volatility traits, together helped hedge against risks.
We believe a strategic combination of these factors can result in a smoother return profile, which should appeal to investors as we embark on another year of shifting market conditions.
