The words small-cap, mid-cap, and large-cap might not mean much to you if you’re a novice investor. They're actually just fancy terms for how much a particular firm has in total capital. For instance, small-cap mutual funds have a smaller market capitalization.

Here are three examples of each type of market capitalization:

As you can see, large-cap firms such as Apple are the most well-known. Other examples of large-cap firms include Alphabet, Starbucks, Amazon and Berkshire Hathaway. Rite Aid Corp. is a great example of a mid-cap firm, and CryoLife, Inc. (NYSE:CRY) is considered a small-cap. If you’ve never heard of a particular small-cap firm, that’s normal. Typically, small-cap funds aren’t as well-known but can still deliver a sizeable punch to your portfolio.

Quick Look: The Best Small-Cap Mutual Funds:

What Are Small-Cap Mutual Funds?

Small-cap refers to companies with a relatively small market capitalization. The official amount of capital may vary slightly amongst traders and the industry, but the market value parameters of outstanding shares in small-cap firms generally range between $300 million and $2 billion.

A small-cap mutual fund is a collection of stocks handpicked by industry experts and sold as a type of pre-packaged bundle. In this case, they’re bundled stock of many small-cap firms, which means they’re more diversified than individual stocks.

Small-cap mutual funds tend to grow more quickly than large-cap mutual funds and usually use their growth to pay for expansion rather than dividends, as these firms are typically looking to grow in order to expand their market share.

Why Invest in Small-Cap Mutual Funds?

Small-cap mutual funds can be a fascinating study, particularly during different points in any market cycle (both bear and bull markets). Here are some inherent characteristics that all small-caps have under their belt:

  • They can be volatile. A bundle of companies exactly like CryoLife, Inc., compared to groups of companies like Alphabet and Starbucks, are going to be able to grow faster than large-cap companies, but they’re also intrinsically less stable because smaller companies can’t weather market storms as well as large-cap firms can. Therefore, they tend to have a higher failure rate.
  • They offer growth opportunities. If you’re a young investor and can stand a little more risk, or if you’re risk-tolerant by nature, the aggressive growth potential of small-cap mutual funds might interest you.
  • Mutual funds ensure that you’re automatically diversified. In short, this means that you don’t put all your eggs in one basket. When you invest in individual stocks, the opposite is true. If one company in your mutual fund bundle has a bad quarter, that likely won’t affect everything else in your portfolio. (On the other hand, if a single stock you’ve invested in goes through a downturn, you might immediately lose money.)
  • Performance can be exceptional. Historically, small-cap stocks have outperformed large-cap stocks. According to Morningstar Ibbotson data, from 1926 through 2012, small-cap stocks averaged an annual return of 12.28% compared to large-caps’ return of 10.08%.
  • Matching your budget. You don’t want to put too many eggs in one basket. So, you can invest in mutual funds with smaller market caps as a way to keep your costs down. You can, of course, expand to pricier assets in the future.
