15 Best Mid-Cap Stocks for 2021

In this article, we discuss the 15 best mid-cap stocks for 2021. If you want to skip our detailed analysis of these stocks, go directly to the 5 Best Mid-Cap Stocks for 2021.

Mid-cap stocks are considered in the middle of small-cap and large-cap stocks. While mid-cap (i.e. mid-capitalization) is generally used to designate companies with a market capitalization between $2 billion and $10 billion, these numbers are subject to change as all stock valuations change over time

One index that tracks mid-cap stocks based in the U.S. is S&P MidCap 400. This index consists of 400 stocks. As of July 30, 2021, the median total market capitalization in the index is at $5.627 billion with the smallest at $1.375 billion and the largest at $18.755 billion.

In the traditional risk vs. reward analysis, small-cap stocks are considered to have the best growth potential than mid-cap and large-cap stocks. However, this growth comes with greater risk. Generally, mid-cap stocks are considered to have a proven track record of profitability while having less volatility during tougher market conditions compared to small-cap stocks. On the other hand, large-cap stocks are seen as less risky albeit with less growth potential compared to mid-cap stocks. Because of this reason, mid-cap stocks can be used in portfolio diversification.

We can see the idea of diversification when comparing S&P MidCap 400 with S&P 500, the S&P index for large-cap companies. Not surprisingly, technology stocks represent 27.2% of all stocks in the S&P 500. In contrast, no sector has 20% or more representation in S&P MidCap 400. Also, industrials and materials sectors account for a combined 26.6% of all midcap stocks while they only account for 11% of large-cap stocks. So, significant differences exist between large-cap and mid-cap stocks when it comes to sectoral breakdown.

Some big-name midcap stocks include Dolby Laboratories, Inc. (NYSE: DLB) known for its audio and video technologies such as Dolby Vision, Five Below, Inc. (NASDAQ: FIVE), the well-known discount store chain, and The Mosaic Company (NYSE: MOS) known for its production of potash and phosphate fertilizers.

The entire hedge fund industry is feeling the reverberations of the changing financial landscape. Its reputation has been tarnished in the last decade, during which its hedged returns couldn’t keep up with the unhedged returns of the market indices. On the other hand, Insider Monkey’s research was able to identify in advance a select group of hedge fund holdings that outperformed the S&P 500 ETFs by more than 124 percentage points since March 2017. Between March 2017 and February 26th, 2021 our monthly newsletter’s stock picks returned 197.2%, vs. 72.4% for the SPY. Our stock picks outperformed the market by more than 124 percentage points (see the details here). We were also able to identify in advance a select group of hedge fund holdings that significantly underperformed the market. We have been tracking and sharing the list of these stocks since February 2017 and they lost 13% through November 16th. That’s why we believe hedge fund sentiment is an extremely useful indicator that investors should pay attention to.

In its Q1 2021 investor letter, Headwaters Capital, an investment management firm, mentioned LendingTree, Inc. (NASDAQ: TREE). Here is what the firm had to say:

“LendingTree is an online marketplace for consumer financial products such as mortgages, credit cards, personal loans and insurance. TREE’s marketplaces connect consumers looking for financial products with lenders and insurance companies, effectively serving as an outsourced marketing partner for lenders and insurance providers. TREE’s results were negatively impacted by ongoing stimulus payments that have served to improve the health of consumer balance sheets and reduce the demand for lending products, specifically credit cards and personal loans. As a result of lower consumer demand for loans, lenders have reined in their marketing budgets, which has translated into lower revenue for TREE. While it is difficult to predict when consumer demand and, consequently, lender marketing budgets will rebound, I do expect both to rebound to pre-COVID levels. Additionally, TREE’s CEO is heavily incentivized to improve performance at the business: he has foregone a salary and has instead accepted a performance-based options grant that can only be exercised once the stock price reaches a minimum hurdle price of $432 (+108% from the current share price). The CEO also has a 16% ownership stake in the Company.”
