Originally posted, 18 Feb 2025 – Three reasons why it may be a mid-cap sweet spot

Key takeaways
Leadership rotation
In recent, months, with little fanfare, mid-cap stocks have taken over market leadership from large caps.
Earnings growth
Mid-cap earnings growth is currently inflecting with 2025 estimates exceeding earnings growth for large caps.1
Better diversification
There’s industry diversification and opportunities to deliver alpha through stock selection within mid cap, in our view.
After an extended period of large-cap leadership, a rotation back to mid-cap leadership already appears in motion with an increasingly attractive setup for 2025. Mid caps outperformed in January as the market has started to broaden.2 We believe it may be a positive setup for the under-invested mid-cap “sweet spot.” Here are three reasons why.
No. 1: Historical and recent outperformance
With an 11.0% annualized return, mid caps have outperformed small caps (9.05% annualized return) and large caps (10.4% annualized return) since the inception of the Russell Midcap Index in 1991.3 And they’ve done this often. Mid caps outperformed large caps 56% of the time and small caps 92% of the time for monthly five-year rolling periods.3
Mid caps have a history of outperformance

An investment cannot be made in an index. Past performance does not guarantee a profit or eliminate risk of loss.
No. 2: Better earnings growth and valuation with potential policy benefits
Mid-cap earnings growth is currently inflecting to the upside, with 2025 estimates exceeding large-caps and at lower valuations.1 Also, while the number and pace of interest rate cuts in 2025 are open questions, the Federal Reserve’s (Fed’s) normalization around current levels has already removed a financing headwind for many mid caps. Our research shows small caps still face significant refinancing risk over the next two to three years. To avoid a negative impact, they would need more cuts than are currently expected.
While the Trump administration’s government policy is still uncertain, potential tariffs and negotiations aimed at stimulating US production would likely be advantageous for mid-cap companies, which tend to be domestic businesses. The potential for lower corporate tax rates in 2025 could benefit all US stocks. If there are additional tax breaks for US production, it could further benefit mid caps. Many of these potential policies should benefit small caps, too; however, we see lower-quality earnings and some offsets that make us less optimistic about them versus mid caps.
Higher growth at a lower price

No. 3: Less concentration = better diversification and opportunity
Much has been made about the concentration of the S&P 500 Index in a select group of mega-cap “Magnificent Seven” stocks — Amazon, Apple, Alphabet, Meta, Microsoft, Nvidia, and Tesla.4 Technology-related businesses now dominate growth-style large cap. There’s more industry diversification and opportunities to deliver alpha through stock selection within mid cap, in our view. Some of the best-performing companies in our mid-cap portfolios are a handful of companies behind NVIDIA’s success or that are benefitting from their ecosystem, not just in tech but across sectors, including industrials and utilities.
What hasn’t been discussed as much is how the best small caps have evolved into attractive mid caps and that the number of investable companies in the small-cap universe has been shrinking. It’s not the size of the companies that’s shrinking. Many of the premier small-cap companies we invest in have more than doubled in size, and many of the best-managed companies have graduated into mid-cap companies because of their success. That’s why we’re seeing higher-quality and better-managed mid-cap companies, while the quality of the small-cap universe hasn’t been refreshed.
A contributing dynamic during the last few years is that new initial public offerings (IPOs) haven’t been added to the small-cap opportunity set. Abundant private equity capital, significant regulatory requirements, and the high costs of going public have led many companies to remain private. In fact, some of the best IPO companies during the last two years were delayed and then came to market as mid caps. While we expect IPOs to improve in 2025, we also expect mergers and acquisitions (M&A) to improve dramatically and keep this dynamic in place.
Optimistic outlook
The economy has shown healthy resilience, and the Fed is patiently normalizing policy with what appears to be a beneficial downward bias. Also, the Intrinsic Value and Discovery Growth teams at Invesco have a unique point of view and competitive advantage in the marketplace. They’re deep and experienced teams with long track records of identifying early-stage small-cap opportunities, which can then compound over time, and they graduate what they believe are the best of them into mid-cap funds.
