Asset manager MFS Investment Management expanded its actively managed ETF lineup last week with the launch of two new funds: the MFS Blended Research Small-Mid Cap ETF (NYSE:BRSM) and the MFS Active International Value ETF (NYSE:MIVL).

• MFS Blended Research Small-Mid Cap ETF stock is testing lower boundaries. Why did BRSM hit a new low?

The funds mark the firm’s latest push into areas of the equity market that have started to gain traction after years of large-cap U.S. stock dominance.

Small- and mid-cap stocks have outperformed large caps so far in 2026, aided by a lower interest-rate environment and improving economic sentiment. The Russell 2500 Index has returned roughly 15% year-to-date, outpacing the approximately 8% gain posted by large-cap benchmarks such as the S&P 500 Index. At the same time, international equities have shown signs of strength this year after a decade of lagging U.S. markets, narrowing valuation gaps that had widened amid the rise of U.S. technology giants.

Key Features of the New ETFs

MFS Blended Research Small-Mid Cap ETF (BRSM)

• Expense ratio: 0.38%
• Targets U.S. companies and REITs within the market-cap range of the Russell 2500 Index
• Uses MFS’s proprietary blended research methodology
• Combines fundamental analysis — including financial condition and industry outlook — with quantitative factors such as price momentum and earnings trends
• Generates a single blended rating that serves as the basis for portfolio construction
• Seeks to maintain portfolio characteristics relatively close to its benchmark while pursuing active security selection

MFS Active International Value ETF (MIVL)

• Expense ratio: 0.57%
• Invests primarily in non-U.S. value stocks
• May allocate a portion of assets to emerging markets
• Not restricted by company size and can invest across the market-cap spectrum
• Focuses on companies believed to be trading below their estimated intrinsic value
• Maintains diversification across countries, sectors, and regions rather than tracking a traditional value benchmark

The two launches build on MFS’s growing ETF platform and follow earlier products such as the MFS Blended Research International Equity ETF (NYSE:BRIE). MIVL also becomes the firm’s third actively managed international equity ETF, further expanding its global investment offerings.
