The Russell Microcap Index, a market cap-weighted equity index maintained by FTSE Russell, is designed to track the performance of the smallest 1,000 companies in the small-cap Russell 2000 Index (RUT), along with the next thousand smallest eligible securities.
Last month, FTSE Russell, the leading global index provider, posted its preliminary lists of companies set to join the Russell Microcap Index as part of its 36th annual Russell US Indexes Reconstitution. The annual Russell rebalancing is typically a high-volume event, with new index additions drawing increased volume from index and fund managers looking to track the performance of the various associated benchmarks.
