Read MoreHide Full Article

Key Takeaways

  • Major U.S. stock indexes hover near record highs, while the S&P 400 mid-cap index is up 4.9% year to date.
  • Mid caps offer diversification, balancing growth potential and resilience against economic swings.
  • DDS, STRL, SNEX, AWI and WTS stand out with strong growth forecasts and favorable analyst estimates.

U.S. stock markets have been witnessing an astonishing bull run since the beginning of 2023 barring some minor fluctuations. The three major stock indexes — the Dow, the S&P 500 and the Nasdaq Composite — are currently rotating around their all-time highs. 

The S&P 500 and the Nasdaq Composite have recorded several all-time highs in 2025. Meanwhile, the mid-cap benchmark — the S&P 400 index — is also up 4.9% year to date. The index is currently 4.6% away from its 52-week high posted on Nov. 25, 2024. 

Investment in mid-cap stocks is often recognized as a good portfolio diversification strategy. These stocks combine the attractive attributes of both small and large-cap stocks. Top-ranked, mid-cap stocks have a high potential to enhance their profitability, productivity and market share. These may also become large caps over time.

If economic growth slows down due to any unforeseen internal or external disturbance, mid-cap stocks will be less susceptible to losses than their large-cap counterparts owing to their lower international exposure. 

On the other hand, if the economy continues to thrive, these stocks will gain more than small caps due to established management teams, a broad distribution network, brand recognition and ready access to capital markets. 

Here, we recommend five mid-cap stocks with a favorable Zacks Rank for the rest of 2025. These are: Dillard's Inc. (DDS - Free Report) , Sterling Infrastructure Inc. (STRL - Free Report) , StoneX Group Inc. (SNEX - Free Report) , Armstrong World Industries Inc. (AWI - Free Report) and Watts Water Technologies Inc. (WTS - Free Report) .
