- Global mid-caps have historically outperformed large caps, including following market selloffs.
- Many mid-caps typically sit on the ‘sweet spot’ of the company lifecycle – offering the similar growth potential of small caps with a risk profile more like large caps.
- Current valuations are attractive on a relative and historical basis.
We cover the numerous reasons in our latest paper The compelling case for a dedicated allocation to mid-cap equities. However, before you read that, here’s a quick run through the evidence.
Global mid-caps – a brief recap
As the name suggests, mid-cap equities are between large caps and small caps in terms of market capitalisation. Looking at the MSCI All Country World Index (ACWI), large caps represent the biggest segment – 70% of the total market cap. At the other end of the scale, small caps make up 15% of the total index market cap, with mid-caps accounting for the middle 15-30% of the entire global equity market cap1.
However, it’s important to understand that while mid-caps are smaller than large caps, they’re not small. In the global equities context, the average market cap of global mid-caps is US$6.1 billion (bn). This is more than four times the average global small-cap size of US$1.3bn, but just a fraction of the average global large-cap size of US$32.6bn2.
In terms of risk/return characteristics, global small caps outperform broader global equities and large caps over the long run3. This, though, is at the expense of more risk. Global mid-caps occupy the middle ground. They outperform large caps and trail small caps, but with considerably lower volatility than the latter.
Furthermore, mid-cap companies combine the attractive traits of both large caps and small caps. Like large caps, mid-cap businesses tend to be diversified in terms of products/business lines and regions. This can provide an element of earnings stability. Additionally, the global mid-cap segment contains many recognised, high-quality companies with proven product and service offerings, which can give a degree of pricing power in tougher times. On the flip side, like small caps, mid-caps tend to have more unexplored organic growth opportunities and greater operational flexibility (including the ability to scale up or down) depending on prevailing conditions.
Given these factors, mid-caps typically sit on the ‘sweet spot’ of the company lifecycle. As you can see from the blue-shaded area below, they tend to be early-to-midlife companies – they are often sufficiently well-established to avoid some of the greater risks of small-cap companies, while at the same time have ample growth opportunities and less risk of demand obsolescence/saturation risk that can affect large-cap companies. That’s why a mid-cap allocation within a global equity portfolio can help investors diversify.
Even with these positives, mid-cap equities are a relatively under-researched part of the market, with global equity investors potentially under-allocating to the asset class. This creates significant opportunities for active investors.

Aside from the structural benefits, we think there’s also a case for global mid-cap equities in the current economic and market environment.
Firstly, as a sector, global mid-caps are full of premier companies, with robust balance sheets and good pricing power. This means there’s a large (cross-sector) pool of global companies that are equipped to deal with today’s challenging economic climate.
Secondly, as shown below, the historically attractive long-term returns of global mid-caps are supported by their track record of bouncing back ahead of large caps, following major drawdown periods.
We believe the case for global mid-caps is clear. They offer the higher growth potential of small caps but with the more controlled risk of large caps. These are ideal dynamics for those looking to diversify their broader equity portfolio. Furthermore, the mid-cap sector is home to numerous leading companies, with robust balance sheets and proven earnings capabilities. This means that many are resilient in the current climate. And yet despite these factors, analyst coverage of mid-caps is relatively poor – creating excellent opportunities for active investors. Finally, relative valuations are presently attractive, with global mid-caps offering an increased discount to global equities.

For more detailed information about Morningstar’s Analyst Rating, including its methodology, please go to: http://corporate.morningstar.com/us/document The Morningstar Analyst Rating for Funds is a forward-looking analysis of a fund. Morningstar has identified five key areas crucial to predicting the future success of a fund: People, Parent, Process, Performance, and Price. The pillars are used in determining the Morningstar Analyst Rating for a fund. Morningstar Analyst Ratings are assigned on a five-tier scale running from Gold to Negative. The top three ratings, Gold, Silver, and Bronze, all indicate that our analysts think highly of a fund; the difference between them corresponds to differences in the level of analyst conviction in a fund’s ability to outperform its benchmark and peers through time, within the context of the level of risk taken over the long term. Neutral represents funds in which our analysts don’t have a strong positive or negative conviction over the long term and Negative represents funds that possess at least one flaw that our analysts believe is likely to significantly hamper future performance over the long term. Long term is defined as a full market cycle or at least five years. Past performance of a security may or may not be sustained in future and is no indication of future performance.
