Understanding market cap:

If you’re investing to pursue long-term financial goals, understanding the relationship between company size, return potential, and risk is critical. Market capitalization—or market cap—refers to the total value of all a company’s shares of stock. It’s calculated by multiplying the price of a stock by its total number of outstanding shares.

Market cap allows you to understand the relative size of one company versus another. There are certain traits that are generally associated with small, mid, and large-cap companies.

Defining U.S. mid-caps:

The Russell Midcap Index is a commonly used index for measuring U.S. mid-cap performance. The Index consists of over 800 companies and represents about 31% of the total U.S. equity market*.

U.S. mid-cap company characteristics

U.S. mid-caps are typically in the high growth stage of their maturity. They combine two positive elements in their business development cycle: accelerated investment growth and tapered business risk. Together, these create an investment “sweet spot.” In addition, they have several attractive business attributes, including:

  • Established products and market strategies
  • Strong historical profitability
  • Well established management teams
  • Long-term growth potential

U.S. mid-caps are often in the process of increasing market share and improving their overall competitiveness. They have generally evolved in their cost efficiencies, product strategies, and key competitive advantages. U.S. mid-caps are established businesses and often fall within industries that are experiencing, or are expected to experience, rapid growth. This stage of growth is likely to determine whether they live up to their full future potential. 

 

Why U.S. mid-caps?

Long-term outperformance

These above characteristics have led to 40+ years of consistent outperformance relative to small and large-cap companies. Data for the small, mid, and large cap companies goes all the way back to 1979 and is shown in the chart below, as illustrated.

Growth of $100,000: Jan. 1979 to Aug. 31, 2021

This line graph shows the growth of $100,000 within U.S. Mid Caps, U.S. Small Caps, and U.S. Large Caps for the period January 1st, 1979 to August 31st, 2021. The U.S. Mid Cap line rises fairly consistently over the long term to reach almost $25,000,000 by August 31st, 2021. The U.S. Small Cap line also rises fairly consistently over the long term, but only reaches approximately $13,000,000 by August 31st, 2021. The U.S. Large Cap line also rises fairly consistently over the long term, but only reaches approximately $16,000,000 by August 31st, 2021.

Strong risk adjusted returns

Mid-caps can bring together some of the best traits of large and small companies: they generally grow faster than large businesses, often with less volatility than small companies. That means they bring the potential for strong capital growth, as well as size diversification. Over the past 20 years, mid-caps have had better risk adjusted returns as shown below:

Mutual funds are subject to fees and expenses that are not applicable to an index, and which reduce returns. Sharpe ratio is a risk-adjusted measure that measures reward per unit of risk taken. The higher the ratio, the better. The numerator is the difference between an annualized return and a risk-free asset. The denominator is measured by annualized standard deviation. Standard deviation measures the degree to which the performance of an asset varies from its average performance during a specific time period. The higher the standard deviation, the greater the volatility (or risk) of performance vs. its average return.

Mid-caps often perform well after market recovery

If you delve even deeper into U.S. mid-cap investment returns, they can be an excellent asset class coming out of financial recessions. Often, mid-cap companies have tended to outperform large companies in the early stages of an economic recovery, as investors begin to take on more risk. For example, after the U.S. recession in the early 2000s, mid-caps outperformed large-caps for three years in a row – from 2003 to 2005. As well, mid-caps did very well after the global financial crisis that occurred from December 2007 to June 20091 . As you can see from the chart below, from 2009 to 2013, mid-cap stocks outperformed their larger-cap counterparts in four out of the five years coming out of that recession.

Calendar year returns (2000-2020)

This bar graph shows the calendar year returns of mid-caps and large-caps for the years 2000 to 2020, which includes the global financial crisis period from December 2007 to June 2009. From 2009 to 2013, mid-cap stocks outperformed large-caps in four out of five years coming out that recessionary period.

More recently, from 2014 to 2020, mid-cap stocks have lagged large caps. This longer cycle of underperformance suggests that mid-caps could be a neglected part of the market today. Additionally, although past performance is not a guarantee of the future, as economies continue to recover from the COVID-19 induced recession in 2020, U.S. mid-caps may prove to be an attractive opportunity in the coming years.

Attractive acquisition targets

Looking beyond returns, mid-caps can also become attractive targets for purchase by large companies. It is often easier for a larger company to buy a particular innovation or product line than it is to build it internally. While the COVID-19 pandemic is not over, the global economy is showing signs of recovery. Recently, in the first two quarters of 2021, 233 merger deals have been announced in the U.S. – which is approximately 96% of the total for all of 2018. Even if merger and acquisition (M&A) activity stays flat later this year, this would be nearly 100% higher than the pandemic disrupted totals in 2020. Deal activity is expected to remain strong heading into 2022.2

This bar graph shows the number of mid-market merger and acquisition transactions from Q2, 2020 to Q2, 2021.  Each of the five bars increases with each quarter, with Q2, 2021 showing approximately 130 mergers and acquisitions.

This may bode well for the subsequent performance of mid-cap stocks, as their stock prices tend to run higher on anticipation of merger rumours.

Academic and analyst coverage

Lastly, academics and fundamental analysts are engaged in researching and measuring the value of securities. Despite the balance of risk and return that mid-caps offer, these academics and analysts may not always pay them the attention that they deserve. Instead, they often favour covering large cap firms or small cap firms (to a lesser degree)3. There are reasons for this, namely that, often, large caps are high profile businesses that frequently receive strong media coverage. Although small cap firms may receive less analyst coverage, they do have a history of academic attention relating to assembling portfolios that is easily built upon. Some investors may assume that they have covered all asset classes by only allocating to small and large-cap stocks, perhaps neglecting mid-caps altogether. The result is that you could be missing out on an important asset class in your investment portfolio.
