CRSP Market Cap indexes are a suite of broad US equity benchmarks which employ CRSP’s proprietary cap-segmentation methodology, which uses a percentage-weight of the total US equity market instead of a simple fixed constituent count to represent each cap-segment. CRSP Market Cap indexes also utilize CRSP-specific index maintenance tools such as migration packeting, banding and transitional reconstitution, to mitigate transaction costs from index changes and better reflect industry practices.
