Guide to Mega Cap Stocks

Mega cap, or “megacap,” is a term that describes the largest publicly-traded companies, based on their market capitalization. Mega cap stocks typically include industry-leading companies with highly recognizable brands.

Investing in mega cap stocks, along with companies that have a smaller market capitalization, can help build a diversified investment portfolio. Spreading investment dollars across different market caps may allow investors to minimize potential risks. But like any security, mega cap stocks have both pros and cons that investors should consider. Learning more about how they work and what sets them apart from other types of stocks can help you decide whether there’s a place for them in your portfolio.

Market Capitalization, Explained

Mega cap stocks sit at one end of the market capitalization spectrum, representing the very largest companies in the public markets. Market capitalization is a commonly used method for categorizing publicly-traded companies. In simple terms, market capitalization or market cap measures a company’s value, as determined by multiplying the current market price of a single share by the total number of shares outstanding.

For example, say a company’s stock is priced at $50 per share and it has 10 million shares outstanding. Following the formula of $50 x 10,000,000, the company would have a total market capitalization of $500 million.

Most often, companies are assigned to one of three categories, based on their market capitalization as follows:

•   Small cap: Market value of $250 million to $2 billion

•   Mid cap: Market value of $2 billion to $10 billion

•   Large cap: Market value above $10 billion

While most companies fit into one of these three groups, some outliers exist on either end of the spectrum. The smallest of the small cap stocks are microcap stocks, while the largest companies are the mega caps.

Mega Cap Stock Definition

Mega cap stocks have a market capitalization that’s significantly beyond $10 billion required for classification of large cap stocks. Instead, these companies have market capitalizations in the hundreds of billions or even of $1 trillion or more.

There are a handful of companies with market caps of more than $1 trillion, and those companies only passed the trillion-dollar mark in recent years. That said, it’s likely more companies will become mega cap stocks in the years ahead.

10 Companies With the Largest Market Cap

As of June 2023, these are the ten companies with the largest market caps. Note, too, that there isn’t always a direct correlation between market cap and stock price!

Apple, which trades under the market ticker AAPL, has a market cap of $2.9 trillion, and shares trade at more than $185. Apple is a tech company that produces consumer tech goods and software, including the iPhone. Its latest quarterly report (Q2 2023) showed revenue of almost $95 billion.

3 Pros of Investing in Mega Cap Stocks

There are several good reasons to consider making mega cap stocks part of your asset allocation strategy.

1. Diversification

Investing across different sectors and market capitalizations spreads out risk, since economic ups and downs may affect smaller, mid-sized and larger companies differently.

2. Stability

Established mega cap companies are among the most stable in the economy and may be better able to withstand a market downturn compared to smaller or newer companies without cash reserves or a solid brand reputation.

3. Dividends

Some mega cap stocks pay dividends to investors since they don’t need to reinvest profits into growth. That can provide an additional stream of income or allow for faster portfolio growth if they’re reinvested.

Cons of Investing in Mega Cap Stocks

While there are some things that make mega cap companies attractive to investors, it’s important to consider the potential downsides:

Limited Upside

Since many mega caps have already done most of their growing, there may be limited space for their share prices to increase.

Perception vs Reality

Market capitalization measures the stock market’s perceived value of a stock, not its intrinsic value. So mega cap status alone shouldn’t be considered a reliable indicator of a company’s fundamentals or financial health.

How To Invest in Mega Caps

If you understand the investment risk and potential rewards that come with mega cap stocks and you’re interested in adding them to your portfolio, there are two ways to do it. You can choose to invest in individual mega cap stocks, or you can put money into an investment fund, such as a mutual fund or an exchange-traded fund (ETF) that holds mega caps.

You can also look at investing in a market index that can give your portfolio exposure to mega cap stocks.

Buying individual stocks allows you to pick and choose which mega caps you want to purchase. But this may require more of a hands-on approach as you’ll need to research individual companies. There are similarities and differences, in that regard, between investing in mega cap and investing in small cap stocks.

Investing in a thematic ETF focused on mega cap stocks may be a simpler way to diversify with larger companies. This allows you to have exposure to more mega cap stocks in your portfolio.

ETFs can be traded on an exchange, just like a stock, allowing for greater liquidity and flexibility than traditional mutual funds. Lower turnover ratios can make ETFs more tax-efficient than regular mutual funds. Depending on which mega cap ETF you choose, you may pay a much lower expense ratio than you would with traditional mutual funds.
