In this article, we will be taking a look at the 10 best mid-cap stocks to buy according to billionaires. 

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.

Mid-caps and large-caps were about equal in terms of earnings growth. He argued, however, that the present value discrepancy did not fairly represent the potential for mid-caps in the future. According to McKnight, mid-cap firms with solid balance sheets and earnings growth on par with large-caps should start to be valued more like their large-cap peers as the year went on and into the following year.

McKnight went on to explain his stance, saying that investors would profit if mid-cap valuations rose from 17x earnings to somewhere between 20x and 21x earnings. At the very least, he reasoned, earnings would start to rise, which would raise mid-caps’ valuation and earnings. On the other hand, he thought that large-cap stocks had less potential for valuation growth and had a hard time defending higher prices, especially in some industries like the MAG7.

Our Methodology

We started by screening for companies with a market capitalization between $2 billion and $10 billion. From this filtered group, we ranked the stocks based on the number of billionaire investors holding positions, using data from the Insider Monkey database. In cases where multiple stocks had the same number of billionaire holders, we used market capitalization as a tiebreaker, giving a higher rank to the company with the larger market cap.

Why are we interested in the stocks that hedge funds pile into? The reason is simple: our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 373.4% since May 2014, beating its benchmark by 218 percentage points (see more details here).

Here is our list of the 10 best mid-cap stocks to buy according to billionaires.

Mesoblast Limited (NASDAQ:MESO) is among the best mid-cap stocks to buy according to billionaires. It is a global leader in developing allogeneic (off-the-shelf) cellular medicines using its proprietary mesenchymal lineage cell technology. The company targets severe inflammatory diseases that lack effective treatment options. Its lead product, Ryoncil (remestemcel-L), became the first and only FDA-approved mesenchymal stromal cell therapy for children with steroid-refractory acute graft versus host disease (GVHD) in March 2025. Following approval, Mesoblast Limited (NASDAQ:MESO) rapidly launched the drug, partnering with over 25 major U.S. transplant centers and securing insurance coverage for over 250 million lives, including mandatory Medicaid coverage in all states.

Ryoncil now benefits from seven years of orphan drug exclusivity and biologic exclusivity until 2036, with intellectual property protection through 2044, effectively limiting competition. The approval marks the foundation of the business’s broader pediatric inflammatory disease franchise, with plans to expand Ryoncil’s use to additional pediatric and adult indications.

The corporation’s manufacturing processes allow scalable production of consistent cell therapies without the need for donor-recipient matching, simplifying access and logistics. The company is also advancing other key candidates: Revascor (rexlemestrocel-L) for ischemic heart failure, which is on track for FDA submission by the end of 2025 under RMAT designation, and a Phase 3 program for rexlemestrocel-L targeting chronic discogenic low back pain, offering a non-opioid alternative for patients.

To support its commercialization phase, Mesoblast Limited (NASDAQ:MESO) strengthened its board with the appointment of Lyn Cobley and was recently added to the S&P/ASX 200 Index. With regulatory momentum, market adoption, and strong IP protection, the company is positioning itself as a major innovator in cellular medicine.

Number of Billionaire Holdings: 8

WK Kellogg Co (NYSE:KLG), an iconic American cereal maker behind brands like Frosted Flakes and Special K, was spun off from Kellogg’s North American cereal business in 2023 to operate as a standalone company focused on cereals. In July 2025, Ferrero Group, a global confectionery giant known for Nutella and Ferrero Rocher, announced a $3.1 billion deal to acquire WK Kellogg Co (NYSE:KLG), taking the company private. The acquisition includes operations in the US, Canada, and the Caribbean and aligns with Ferrero’s strategy to expand in North America and diversify into the ready-to-eat cereal market.

The deal comes at a pivotal time for the company, which has been working to modernize its operations and revamp its product portfolio. Despite a 2% sales decline in 2024 due to shifting consumer preferences toward healthier and more affordable options, the business grew its EBITDA by 7.5% through a $500 million multi-year supply chain modernization plan. This effort includes a $200 million investment in 2025 to improve production efficiency, reduce waste, and strengthen margins. For investors looking at the best mid-cap stocks poised for transformation, KLG stood out as a promising candidate due to its strategic turnaround initiatives and strong brand recognition.

In parallel, the business has been launching innovation-driven “food platforms,” introducing new on-the-go formats and healthier variants of popular cereals like Blueberry Bran Crunch. These moves aim to reposition the brand in a category facing stagnant growth and evolving consumer habits.

Ferrero’s acquisition is expected to accelerate these efforts by bringing in additional capital, marketing strength, and product innovation expertise. Analysts believe the combination of WK Kellogg Co (NYSE:KLG)’s brand equity and Ferrero’s operational capabilities could reinvigorate the cereal business and improve competitiveness against established players like General Mills. The focus on modernization and health-oriented product expansion sets a strong foundation for future growth under Ferrero’s leadership.
