The Center for Research in Security Prices, LLC is a provider of historical stock market and investable index data. CRSP was owned by the University of Chicago and managed by its Booth School of Business until February 2026. In February 2026, the acquisition of CRSP brought the CRSP Market Indexes—benchmarks for over $3 trillion in U.S. equities—into the Morningstar Indexes family. Additionally, the CRSP Research Data Products, renowned for their academic rigor, historical depth, and accuracy, will further enhance Morningstar’s equity research and data capabilities. This integration unites two trusted sources of market insight, reinforcing a shared commitment to transparency, quality, and investor-focused solutions.
