On July 1, Alan McKnight, the CIO at Regions Wealth Management, appeared on CNBC to explain how his biggest worry is currently centered around uncertainty, which he believes leads to volatility. He pointed to the situation in Washington and ongoing trade policy discussions as examples. McKnight emphasized that businesses and investors desire clarity to allocate capital going forward. However, at the same time, McKnight has shown a lot of interest in mid-cap stocks. He noted that mid-caps had taken a bit longer to gain momentum. From an earnings growth perspective, mid-caps and large-caps were almost on par. However, he contended that the current valuation disparity did not accurately reflect the future opportunity in mid-caps. McKnight predicted that as the year progressed and into the next year, mid-cap companies with strong balance sheets and earnings growth comparable to large-caps should begin to receive a valuation more in line with their large-cap counterparts.

McKnight further clarified his position and stated that if mid-cap valuations increased from 17x earnings to somewhere between 20x and 21x earnings, investors would benefit. He reasoned that earnings would at least begin to grow and lead to growth in both valuation and earnings for mid-caps. Conversely, he believed that large-caps had limited room for valuation expansion, finding it difficult to justify higher valuations, particularly in certain sectors, such as the MAG7.

That being said, we’re here with a list of the 12 best performing mid cap stocks so far in 2025.
