MFS Active Mid Cap ETF (MMID)

The MFS Active Mid Cap ETF is an actively managed U.S. equity fund from MFS Investment Management, the Boston-based firm that launched the first U.S. open-end mutual fund in 1924. It seeks capital appreciation by investing primarily in mid-capitalization companies.

Portfolio managers rely on MFS's fundamental research to identify mid-size companies with durable business models and attractive growth or valuation characteristics, building the portfolio through individual stock selection rather than tracking a mid-cap index.
