Small cap, mid cap, or large? The right mix for your portfolio | Money Under 30 (2024)

Is buying and selling stocks on a daily basis the right approach? And is it even realistic?

Stock picking can sometimes be rewarding, but it’s a dangerous game if you don’t know what you’re doing. It’s also risky if you’re not investing enough money to be well-diversified.

As a new investor, you’re going to be better off investing in a broad mix of stocks and bonds. You can easily do this by putting your money into ETFs and mutual funds.

But where you do start? How do you know which investments are right for you? And what about asset allocation?

In this post I’ll break down the most common types of ETFs and mutual funds. I’ll also explain market capitalization and its importance to your investment strategy.

Finally, I’ll cover asset allocation and show you just how to quickly build a diversified portfolio.

What is market capitalization?

Before understanding the different types of mutual funds and ETFs, you need to understand market capitalization, or market cap. Market cap is a quick way of determining how large a company is.

To calculate market cap, take the share price and multiply it by the number of shares outstanding (meaning shares that anyone can buy). This will give you a dollar amount, which is the company’s market cap.

Here are the most common names you’ll see, as well as their corresponding market caps:

  1. Large cap – $10-$200 billion
  2. Mid cap – $2-$10 billion
  3. Small cap – $250 million-$2 billion

For example, let’s say Company A has a stock price of $10 and has 1 million shares outstanding. Their market cap would be:

$10 x 100,000,000 shares = $1,000,000,000

So Company A has a market cap of $1 billion. According to the list above, this would make them a small-cap company.

Mutual funds and ETFs will often categorize themselves by the size of companies that they invest in. For example, a large-cap ETF will hold stock in only large-cap companies.

There are a few other types of market caps you may see used as descriptors, but not as often. They are: mega cap (above large cap, > $200 billion), micro cap (under small cap, < $250 million), and even nano cap (usually <$50 million).

Why you should consider smaller companies for your investing strategy

Investing in small-cap companies is an important element ofyour investment strategy. Smaller companies tend to have a greater chance of large growth, faster.

For instance, a company with a market cap of $500 million is more likely to double in value than a company with a market cap of $500 billion. It’s also more likely to cut in half, which is why potential is such a keyword.

Smaller companies also don’t have as much analyst coverage as large companies. This leaves room for smaller companies to go unnoticed. If you’re putting time into research, you can find smaller companies that are very profitable.

Lastly, small cap companies have the ability to outperform large cap companies, per a 1993 publication by Eugene Fama and Kenneth French.

This doesn’t come without risk, though. There are some factors to consider before investing in smaller companies. Smaller companies are more volatile.

While you may get a larger return on your investment, you also open yourself up to more risk. Many smaller companies have not been around as long and may not last.

This is the beauty of small-cap ETFs and mutual funds. You don’t have to pick individual small companies to invest in. You immediately diversify yourself and invest in a basket of smaller companies.

So while investing in a small-cap ETF or mutual fund can be riskier than investing in a large-cap fund, it’s a necessary element ina diversified portfolio. Remember, rewards don’t come without risks in investing.

Ideal asset allocation (and how to choose)

One thing to consider is your own personal level of risk tolerance. Everyone’s asset allocation for stocks is going to be different based on the level of risk that they’re willing to take on.

The first thing to consider is your allocation between stocks and bonds. As a younger investor, you have the ability to take on more risk. This is because the timeline before retirement is much further out for you than somebody who is closer to retirement age.

Because of this, I recommend no more than 10% of your portfolio in bonds. The other 90% should be broken up into four fund classes: large cap, mid cap, small cap, and international.

The percentage allocation that I recommend is:

  • 30% large cap
  • 20% mid cap
  • 20% small cap
  • 20% international
  • 10% bonds

This will give you a well-balanced and diversified portfolio and allow you to tap into foreign markets and have some bond stability.

There are also some services that will choose an asset allocation for you. This can be good if you’re unfamiliar with investing or don’t want to put the time into figuring out what’s right for you. The downside is that you lose the ability to choose a specific allocation of investments that fit your strategy.
