AI-focused large-cap growth stocks fueled much of this year’s stock market performance, leading investors to believe that the rally could be losing steam due to frothiness and lofty market valuations. Where can they turn for additional upside heading into 2026? Midcaps could offer a solution.

From a pure performance perspective, small-caps can provide outsize gains relative to their large-cap peers. But some risk averse investors don’t want the high-beta volatility associated with small-caps.

“Smaller companies often undergo faster growth than more mature firms, but they can also add volatility to a portfolio,” Morningstar noted, highlighting the strength in midcap equities funds, especially those that are concentrated on growth.

As such, they can opt to take a median option with midcap equities. Midcaps offer investors a Goldilocks solution, balancing the stability of large-caps while also exhibiting growth characteristics of small-caps.

The prospect of additional interest rate cuts could also provide more tailwinds for midcap performance. That’s especially the case for midcap companies that rely on debt to fund their operations. These companies will benefit from lower debt servicing costs, which will allow them to free up cash for reinvestment into their operations.

The upside that midcap equities provide in the current market environment makes exposure to a fund like the MFS Active Mid Cap ETF (MMID) ideal. Furthermore, it adds an additional edge with its active management.

The Active Edge With Mid Caps

The active management strategy employed by MMID adds inherent benefits to investors. In addition to broad-market systematic risks, MMID’s active managers can mitigate idiosyncratic risks associated with midcap equities that are not privy to large- or small-cap companies. This active advantage offers a higher degree of market flexibility versus their passive peers, because they aren’t tethered to an index.

In times of uncertainty, MFS portfolio managers can adjust the holdings of the funds to mitigate downside risk. Additionally, they can capture upside when these midcap companies trend higher. The active edge can thrive in any market environment and thus underpins the MFS active ETF product suite.

“Our active ETF lineup reflects our time-tested investment approach and some of our most popular investment strategies,” MFS noted on their active ETF product suite brochure. “The same approach that has fueled their success fuels our ETFs.”
