In this article, we will take a look at the 10 best mid-cap growth ETFs to buy.
Around 20% of the total market capitalization of the US equity market is represented by mid-cap companies with a market cap between $2 billion and $15 billion. According to VettaFi, there are around 23 exchange-traded funds (ETFs) that can be considered as mid-cap growth ETFs with a combined asset under management (AUM) of $169.8 billion. The size of the ETF industry assets stood at $7.3 trillion at the end of the second quarter of 2023. Investors often consider mid-cap companies as an attractive investment option due to their potential for significant growth, which can surpass what large-cap and mega-cap corporations offer. Moreover, mid-cap companies typically maintain a more stable and secure business model compared to their smaller counterparts. According to the US Bureau of Labor Statistics (BLS), 30% of new businesses cease their operations within a brief period of two years from inception. This figure increases to 45% after five years and 65% after a decade. Historically, mid-cap companies have grown to become large-cap or mega-cap companies with a heavily defendable business model. Interestingly, mid-cap ETFs have not garnered as much attention as their large-cap and mega-cap counterparts and have observed a net outflow of $106 billion in the last five years. Furthermore, the number of mid-cap active funds saw a decline between 2003 and 2018 from 371 to 301. Meanwhile, the number of large-cap funds remained consistent at 816 during the same period.
According to S&P Dow Jones Indices, mid-cap stocks have received the lowest asset allocation historically, even lower than that allocated to the small-cap universe. Despite the prevailing beliefs and recent trends, data reveals that mid-cap stocks have actually outperformed both large-cap and small-cap stocks. Since December 1994, the S&P MidCap 400 has outperformed the S&P 500 by 2.03% and the S&P SmallCap 600 by 0.92% on an annualized basis. Some of the best mid-cap stocks, such as Vistra Corp. (NYSE:VST), and Bill.com Holdings, Inc. (NYSE:BILL), Antero Resources Corporation (NYSE:AR), are now attracting hedge fund attention. Here’s what TimesSquare Capital said about Antero Resources Corporation (NYSE:AR) in its Q3 2022 investor letter:
“New to the portfolio this quarter is Antero Resources Corporation (NYSE:AR), a natural gas focused exploration and production company with operations in Pennsylvania and Ohio. The continued buildout of U.S. liquefied natural gas stems from utility plants switching from coal to natural gas and European demand.”
Trends in Mid-Cap Funds and US Equity Market
In the short term, mid-cap funds have experienced a net outflow of funds, while the overall US equity market witnessed a net inflow of $9.7 billion during the week ending on September 13, as reported by LSEG. Experts believe that mid-cap companies are losing against large-cap corporations because mid-cap companies do not have the same level of opportunity to access low-cost labor markets outside the US by outsourcing their operations. Furthermore, they are not able to tap less regulated markets overseas. These factors act as a bottom-line booster for large-cap stocks. There is also a widespread belief that mega-cap and large-cap companies continue to outperform mid-cap companies during extended periods of slow economic growth. This is because large-cap companies can cut costs more effectively through restructuring and other efforts as compared to their mid-cap counterparts.
It must be noted that mid-cap companies are usually acquisition targets by large-cap companies. There have been numerous examples of mid-cap companies getting acquired by mega-cap or large-cap behemoths in the recent past. Microsoft Corporation (NASDAQ:MSFT), for instance, has been at the forefront of this strategy as it has completed several acquisitions in the last decade. The Redmond, Washington-based company completed the takeover of Skype Technologies for a sum of $8.5 billion in 2011. The acquisition aided Microsoft Corporation (NASDAQ:MSFT) in integrating live audio and video communications platforms into its operating system and gaming console. Similarly, the company completed the acquisition of ZeniMax Media in September 2020 for $8.1 billion to boost its gaming division. Furthermore, Microsoft Corporation (NASDAQ:MSFT) acquired the devices and services division of Nokia Oyj (NYSE:NOK) for $7.2 billion in September 2013 to double down on its bet on mobile devices. The Seattle, Washington-based technology conglomerate Amazon.com, Inc. (NASDAQ:AMZN) also implemented a similar strategy of boosting its digital content platform through the acquisition of Metro-Goldwyn-Mayer (MGM) for $8.50 billion in May 2021. The near-century-old studio had a content library that comprised over 4,000 film titles and 17,000 TV episodes.

“We have had some extraordinary winners over time. For instance, we bought DexCom, Inc. at a $950 million market cap in 2012, and it is now valued at $50 billion (the stock has appreciated 41% annually since the Fund’s initial purchase). TransDigm Group Incorporated has grown from $1.1 billion at purchase to $49 billion presently (and the stock has appreciated 29% annually since the Fund’s initial purchase 17 years ago). IDEXX Laboratories, Inc. (NASDAQ:IDXX) has gone from $2 billion at purchase to $42 billion over almost 15 years and the stock has appreciated 26% annually during that time frame. The Trade Desk is now valued at $38 billion and was $433 million when we first purchased shares over 6 years ago. The stock has appreciated almost 60% annually since our initial purchase. Pretty amazing. All four stocks have been solid performers this year, contributing nicely to the Fund’s returns.
Since we run a small-cap fund but want to hold on to these great investments as they continue to compound and perform, we reduce the positions sizes over the holding period so that the overall market capitalization of the Fund is palatable. For each of the four stocks mentioned above, we presently own 11% or less of our peak positions. We take the proceeds from the trimming of these positions to fund new small-cap investments, with the hopes of somehow replicating these results.”
