The S&P MidCap 400 is an index by Standard & Poor's (S&P), comprising 400 companies with market capitalizations between $3.6 billion and $13.1 billion. Launched in 1991, it's a key indicator for U.S. stock market trends.
Tracking Mid-Size US Companies
The S&P MidCap 400 Index tracks U.S.-based companies with market capitalizations between $3.6 billion and $13.1 billion. To qualify, companies must have a minimum investable weight factor of 0.10 and be listed on an exchange. This includes equities like real estate investment trusts (REITs) but excludes closed-end funds, American depositary receipts (ADRs), and exchange-traded funds (ETFs).
The index employs a market-cap-weighted system, giving greater influence to larger-cap companies. Each company's weight is determined by dividing its market cap by the total market caps of all 400 companies in the index.
It is recalculated quarterly (March, June, September, December) and available in various currencies. As of April 30, 2021, the top sectors were industrials (18.5%), financials (15.9%), consumer discretionary (14.8%), information technology (13.4%), and health care (11.7%). The top five holdings included Bio-Techne, Charles River, Fair Isaac & Co, Cognex, and Molina Healthcare.
