Beyond being a familiar adage, “quality over quantity” lies at the heart of quality-based investing. Rather than concentrating on the largest stocks, quality indices systematically tilt toward companies with strong profitability, high earnings quality and robust balance sheets. Over the long term, the S&P 500® Quality Index has delivered impressive absolute and risk-adjusted returns as…

Research and development (R&D) investment is often a key indicator of innovation, competitiveness and a forward-looking mindset—qualities that may drive future revenue streams and market leadership. Comparing R&D Intensity1 across companies can help identify those that are dedicating significant resources to developing new products, technologies or services capable of disrupting industries and generating lasting value….

Over the long term, both the S&P 500® Quality Index and S&P 500 Momentum Index have outperformed the broader market (as measured by the S&P 500) in terms of absolute and risk-adjusted returns. The quality factor emphasizes financially strong and stable companies, while momentum tracks stocks with sustained price trends. When combined, these strategies create…

The S&P 500® continues to be a trusted benchmark for the broad U.S. market, measuring the performance of U.S. large-cap companies across various sectors. As the market moves, certain stocks and sectors grow to represent a larger share of the index, highlighting their significant influence on the economy. While this is the natural result of…

By weighting the constituents of the S&P 500® based on top-line revenue, the S&P 500 Revenue-Weighted Index offers an alternative to traditional benchmarks that are weighted by float market cap (FMC). This approach aims to better reflect the fundamental strength of each company, while offering better valuations and enhanced diversification. In this blog, we will…

Amid macroeconomic uncertainty and elevated volatility, the S&P 500® has experienced a notable decline. In the challenging market conditions from Dec. 31, 2024, to April 4, 2025, the S&P 500 Quality Index not only outperformed the S&P 500 but also showcased its defensive characteristics, which have been evident throughout its history. In this blog, we…
