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.
