CRSP Market Indexes are trusted by leading asset managers and investors to benchmark U.S. equities across market capitalizations, investment styles, and sectors.
Nearly $3 trillion in fund assets are linked to CRSP Market Indexes. This includes the world’s largest mutual fund, which tracks the CRSP US Total Market Index, the industry standard for measuring the complete U.S. domestic equity market. Built with academic rigor but designed to reflect how professional managers actually invest, CRSP Market Indexes are the serious choice for serious investors.
CRSP capitalization-weighted indexes strive to be the most accurate reflection of the U.S. equity markets. Unlike other benchmarks, membership in CRSP Market Indexes is based not on an arbitrary fixed constituent count but on a percentage-weight of the market. This represents a more accurate reflection of each capitalization segment of the market. And by utilizing index rebalancing and migration methodologies that match how investors manage money in the real world, CRSP Market Indexes help reduce turnover and mitigate transaction costs.
CRSP Value Indexes use a transparent, rules-based multi-factor scoring approach to classify securities based on Value characteristics that align with how fundamentally driven investors define this style. This methodology considers each security’s price relative to book value, sales, dividends, historic earnings, and forward earnings to ensure style purity.
In the real world, investment managers utilize multiple metrics to identify investment styles such as Growth. So does CRSP. CRSP Growth Indexes score companies on future long-term earnings per share growth, future short-term EPS growth, and historic earnings and sales over the past three years. They also rely on key ratios, including a security’s current investments-to-assets ratio and return assets.
Sector indexes are only as good as the broad market index from which they are created. CRSP Sector Indexes start from the CRSP US Core Cap Index. From there, CRSP utilizes the Uniform Entity Sectors (UES) system — with 11 sectors— to assign companies to specific parts of the market to ensure that all companies are assigned to their appropriate sectors.
As of July 1, 2026, CRSP has terminated the calculation and publication of the CRSP ISS ESG Indexes.
