Many investors overlook mid-cap stocks, partly because they’re not as financially stable as large-cap stocks and partly because they’re not growing as quickly as small-caps. But mid-cap stocks offer a mix of both – solid growth and financial stability. If you don’t want the hassle of investing in individual stocks, you can gain exposure to mid-cap stocks through an ETF.
What is a mid-cap ETF?
A mid-cap ETF is an exchange-traded fund that invests in the market’s mid-size companies, where the total value of the company’s stock ranges from a few billion dollars to $20 billion or so. Mid-cap ETFs are a great way to own the companies that are growing quickly and have good financial stability without having to analyze individual stocks and picking the winners.
The mid-caps include plenty of companies that you haven’t heard of as well as quite a few that you may use in your daily life. And the best of the mid-cap stocks will continue to grow larger, ultimately becoming large-caps and multiplying your initial investments many times over.
Mid-cap companies may be popular with investors for a few reasons:
- Growth: Mid-cap businesses are still small enough that they offer above-average growth and sometimes well above-average, as many mid-caps go on to become large-caps.
- Increasing financial stability: Along with their increasing size comes greater financial stability and resources, making mid-caps more secure than small-caps though not as secure as large-caps or the mega-cap companies such as Apple and Amazon.
- Defensive businesses: Mid-cap companies have typically grown to become large enough that they’re able to defend a business niche, increasing their overall safety.
- Less volatility: Because they’re more secure, mid-caps tend to have less volatility than their smaller rivals, making them a bit better for risk-averse investors.
Those are great positives for investors, but if you have no interest in investing yourself and don’t want to do the legwork of research and analysis, a great place to begin is buying a mid-cap ETF. (And here are the best small-cap ETFs and best large-cap ETFs based on their overall returns.)

Mid-cap ETFs are an attractive way to invest in solid performers that have both growth and stability — and to do so without the risks of buying into individual stocks. While an ETF can help diversify the risk of buying a few individual stocks, it won’t eliminate all the risk of investing.
