Mid cap stocks represent a significant portion of the U.S. equity market—about 23%—but they only account for 10% of investment exposure (as of 12/31/2023)1. With mid caps being under-allocated to and overlooked, it’s not surprising that so many investors are still unaware of the benefits of mid cap investing.

Mid Cap Stocks: An Investment Opportunity in the “Sweet Spot”

Mid cap stocks offer a unique investment opportunity for those seeking a balance between growth and stability. With market capitalizations ranging from $1 billion to $50 billion, mid caps sit in a sweet spot between large, well-established companies and smaller, higher-risk enterprises. Despite being overlooked, mid cap companies are typically more stable than small caps while still offering considerable growth potential compared to their large cap counterparts. This blend of dependability and growth potential makes mid caps an appealing choice for investors looking to diversify their portfolios.

What Defines a Mid Cap Company?

Mid caps typically fall between the largest 200 companies and those with market caps below $1 billion. There is usually some overlap between large and mid, and mid and small caps, as can be seen in market indexes like the Russell 1000® Index, where the bottom 800 companies form the Russell Midcap Index. The 800-stock overlap between the Russell 1000® and Russell Midcap Indices, however, is not as significant as it may seem. Due to index weighting by market capitalization, the largest 20% of stocks in the Russell 1000 Index account for approximately 77% of the index.

Mid Caps vs. Large and Small Caps

Because of their size, established business models, and access to capital, mid cap companies offer unique qualities compared to large and small caps. Some of these qualities include:

  1. Nimbleness: Mid cap business models are typically more established than small cap companies, yet less complex than large caps, which allows them to be nimble and adapt more easily to changing economic conditions.
  2. Lower risk exposure: Compared to large caps, mid caps generally generate most of their revenue within the U.S. This means that they are less exposed to international risks and currency fluctuations.
  3. Valuation opportunities: Mid caps are less closely followed by Wall Street analysts compared to large cap companies2. This gives active investors the chance to discover undervalued stocks with strong growth potential.

Mid Cap Risk and Return Performance

Historically, mid cap stocks have delivered strong returns with lower volatility compared to both large and small caps. Over the past 25 years, mid caps returned an average of 9.3% annually, outpacing both large caps like the S&P 500 or Russell 1000, which returned 7.6% and 7.7%, respectively, and small caps, which returned 7.9%. Additionally, mid cap stocks have shown resilience in recovering from economic downturns. In the three years following the last three significant market declines3, mid caps outperformed large cap stocks by an average of 32.8 percentage points. This historical performance demonstrates the strength of mid caps in navigating challenging economic periods.

Equity risk is the risk that securities held by the fund will fluctuate in value due to general market or economic conditions, perceptions regarding the industries in which the issuers of securities held by the strategy participate, and the particular circumstances and performance of particular companies whose securities the fund holds. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

An investment in the Fund is subject to risk and there can be no assurance the Fund will achieve its investment objective. The risks associated with an investment in the Fund can increase during times of significant market volatility. Investments in midsize companies may entail greater risks than investments in larger, more established companies. Midsize companies tend to have narrower product lines, fewer financial resources, and a more limited trading market for their securities, as compared to larger companies. They may also experience greater price volatility than securities of larger capitalization companies because growth prospects for these companies may be less certain and the market for such securities may be smaller. Some midsize companies may not have established financial histories; may have limited product lines, markets, or financial resources; may depend on a few key personnel for management; and may be susceptible to losses and risks of bankruptcy. More detailed information regarding these risks can be found in the Fund’s prospectus.
