What is the difference between index funds and single stocks?
The Bottom Line
Individual stocks may rise and fall, but indexes tend to rise over time. With index funds, you won't get bull returns during a bear market. But you won't lose cash in a single investment that sinks as the market turns skyward, either. And the S&P 500 has posted an average annual return of nearly 10% since 1928.
An index fund is a portfolio of stocks or bonds designed to mimic the composition and performance of a financial market index. Mutual funds and exchange-traded funds (ETFs) have many different varieties of low-cost index funds. They have lower expenses and fees than actively managed funds.
All investments carry some degree of risk and can lose value if the overall market declines or, in the case of individual stocks, the company folds. Still, mutual funds are generally considered safer than stocks because they are inherently diversified, which helps mitigate the risk and volatility in your portfolio.
Cons include more difficulty diversifying your portfolio, a potential need for more time invested in your portfolio, and a greater responsibility to avoid emotional buying and selling as the market fluctuates.
Disadvantages include the lack of downside protection, no choice in index composition, and it cannot beat the market (by definition).
If you're new to investing, you can absolutely start off by buying index funds alone as you learn more about how to choose the right stocks. But as your knowledge grows, you may want to branch out and add different companies to your portfolio that you feel align well with your personal risk tolerance and goals.
Is Investing in the S&P 500 Less Risky Than Buying a Single Stock? Generally, yes. The S&P 500 is considered well-diversified by sector, which means it includes stocks in all major areas, including technology and consumer discretionary—meaning declines in some sectors may be offset by gains in other sectors.
Individual stock ownership may offer benefits that fit your investment needs, but you should consider the trade-offs to owning a large number of individual stocks. If you want the control and involvement of choosing which stocks to own, individual stocks may fit your needs.
As with other mutual funds, when you buy shares in an index fund you're pooling your money with other investors. The pool of money is used to purchase a portfolio of assets that duplicates the performance of the target index. Dividends, interest and capital gains are paid out to investors regularly.
Why would someone choose a mutual fund over a single stock?
The primary reasons why an individual may choose to buy mutual funds instead of individual stocks are diversification, convenience, and lower costs.
Index funds hold investments until the index itself changes (which doesn't happen very often), so they also have lower transaction costs. Those lower costs can make a big difference in your returns, especially over the long haul.
Investing in an individual stock can deliver very high returns, and you won't be taxed on any capital gains until you sell, in a taxable account. A single stock can potentially return a lot more than an ETF, where you receive the weighted average performance of the holdings.
Therefore, sticking to the rule of keeping no more than 10-15% of your overall portfolio invested in a single stock may become even more critical of a benchmark to follow both to mitigate volatility, potential returns, and hazards to your overall financial life.
Market risk: The stock market is volatile and can experience significant swings in price. If you have all of your money invested in a single stock, you are exposed to all of the risk associated with that stock. If the stock price falls, you could lose a significant amount of money.
There is no set definition for what makes a concentrated position. When an investment in a single stock represents more than 5% of a portfolio, T. Rowe Price advisors consider it to be worth addressing. Once a holding exceeds 10%, however, it represents a greater risk that requires more immediate planning.
It's easy to see why S&P 500 index funds are so popular with the billionaire investor class. The S&P 500 has a long history of delivering strong returns, averaging 9% annually over 150 years. In other words, it's hard to find an investment with a better track record than the U.S. stock market.
Another reason some investors don't invest in index funds is that they may have a preference for investing in a particular industry or sector. Index funds are designed to provide exposure to broad market indices, which may not align with an investor's specific interests or values.
Lack of Global Diversification
The S&P 500 is all US-domiciled companies that over the last ~40 years have accounted for ~50% of all global stocks. By just owning the S&P 500 you miss out on almost half of the global opportunity set which is another ~10,000 public companies.
The important thing to remember about index funds is that they should be long-term holds. This means that a short-term recession should not affect your investments.
Are index funds 100% safe?
Because the goal of index funds is to mirror the same holdings of whatever index they track, they are naturally diversified and thus hold a lower risk than individual stock holdings. Market indexes tend to have a good track record, too.
Investing in an S&P 500 fund can instantly diversify your portfolio and is generally considered less risky. S&P 500 index funds or ETFs will track the performance of the S&P 500, which means when the S&P 500 does well, your investment will, too. (The opposite is also true, of course.)
According to our calculations, a $1000 investment made in February 2014 would be worth $5,971.20, or a gain of 497.12%, as of February 5, 2024, and this return excludes dividends but includes price increases. Compare this to the S&P 500's rally of 178.17% and gold's return of 55.50% over the same time frame.
In 1980, had you invested a mere $1,000 in what went on to become the top-performing stock of S&P 500, then you would be sitting on a cool $1.2 million today.
Think About This: $10,000 invested in the S&P 500 at the beginning of 2000 would have grown to $32,527 over 20 years — an average return of 6.07% per year.
