What you can actually invest in with a Roth IRA

A Roth IRA is a container—a tax-advantaged account at a bank or brokerage. What you put inside that container is up to you. Most Roth IRAs hold one or more of these: individual stocks, mutual funds, exchange-traded funds (ETFs), bonds, or cash. Some custodians also allow real estate or precious metals, though that is less common and usually requires a self-directed IRA.

The tax benefit of a Roth IRA—withdrawing money tax-free in retirement—applies to whatever you invest in. The investment choice itself is separate from the account type. You could hold the exact same mutual fund inside a Roth IRA or inside a regular taxable brokerage account; the difference is the tax treatment, not the fund itself.

Your choice of what to invest in depends on three things: how much risk you can tolerate, how long until you need the money, and how much time you want to spend managing it.

Key Takeaways

  • A Roth IRA is an account type; what goes inside it—stocks, bonds, mutual funds, ETFs—is your choice, and different custodians offer different options.
  • Target-date funds automatically shift from stocks to bonds as you approach retirement, so they require almost no decision-making after you buy them.
  • Index funds and ETFs track a broad market index with low fees, making them a common choice for people who do not want to pick individual stocks.
  • Individual stocks and bonds give you more control but require more research and monitoring, and most people do better with a diversified fund.
  • Your brokerage or bank sets the menu of what you can invest in; not all custodians offer all options, so check before you open the account.

Target-date funds: the set-and-forget option

A target-date fund is a mutual fund that holds a mix of stocks and bonds. The fund automatically rebalances—shifting money from stocks toward bonds—as you get closer to the year you plan to retire. If you open a Roth IRA at age 30 and plan to retire at 65, you might buy a target-date 2055 fund. That fund starts aggressive (mostly stocks) and gradually becomes more conservative (more bonds) over the next 25 years.

You buy it once and do nothing else. The fund manager handles all the rebalancing. This works well if you do not want to think about your investments or do not have time to monitor them. Vanguard, Fidelity, and Schwab all offer target-date funds with low fees. The exact mix of stocks and bonds varies slightly by company, so if you are comparing them, look at the fund prospectus to see the current allocation.

The downside is that you have less control. You cannot adjust the risk level mid-year if your circumstances change, and you are paying a fund manager to do the rebalancing for you—though the fees are usually small, often under 0.15% per year.

Index funds and ETFs: broad market exposure with low fees

An index fund is a mutual fund that tracks a market index—a pre-set list of stocks or bonds. The S&P 500 index fund, for example, holds shares in 500 large U.S. companies in the same proportions as the index itself. An ETF (exchange-traded fund) does the same thing but trades like a stock during market hours instead of settling at the end of the day.

Both give you instant diversification: one purchase gives you exposure to hundreds or thousands of companies. Fees are typically very low—often 0.03% to 0.20% per year—because the fund simply copies the index rather than paying a manager to pick stocks. For most people, a simple portfolio of two or three index funds (one U.S. stock fund, one international stock fund, one bond fund) is enough.

The trade-off is that you move with the market. You cannot beat it, but you also will not fall behind it by much. If the S&P 500 drops 20%, your S&P 500 index fund drops 20% too. That is fine if you have decades until retirement, but it can be uncomfortable if you are close to needing the money.

Individual stocks and bonds: higher control, higher effort

You can buy individual company stocks or bonds directly inside a Roth IRA. This gives you complete control: you decide which companies to own and in what proportion. Some people enjoy researching companies and building a portfolio this way.

The downside is significant. You need to research each holding, monitor it regularly, and rebalance manually. A single company can fail or underperform, so you need to own many stocks to spread that risk—which means a lot of work. Most people who try this end up underperforming a simple index fund, partly because of the time cost and partly because picking individual winners is genuinely difficult.

Individual stocks and bonds make sense if you have strong knowledge of a particular company or sector, or if you enjoy the research. Otherwise, a fund is usually the better choice.

How your brokerage or bank limits your choices

Not every custodian offers every investment. A bank-based Roth IRA might offer only CDs, money market funds, and a few mutual funds. A brokerage like Fidelity or Charles Schwab offers thousands of stocks, ETFs, and mutual funds. Some custodians charge per trade or per fund; others charge nothing.

Before you open a Roth IRA, look at what the custodian actually offers. If you want to buy a specific fund or stock, confirm that the custodian carries it. If you want low fees, compare the expense ratios of their funds—the annual percentage you pay to hold them. A difference of 0.10% per year does not sound like much, but over 30 years it compounds into real money.

Matching your investment to your timeline

The longer you have until retirement, the more risk you can take. If you are 25 and will not touch the money for 40 years, a portfolio of 90% stocks and 10% bonds is reasonable—you have time to recover from downturns. If you are 60 and plan to retire in five years, 30% stocks and 70% bonds makes more sense.

A target-date fund handles this automatically. If you are building your own portfolio with index funds, a common rule of thumb is to hold your age in bonds and the rest in stocks—so at 35, you might hold 35% bonds and 65% stocks. This is not a rule, just a starting point. The key is that you should be comfortable with the worst-case scenario: if the stock market drops 30%, can you stay invested without panic-selling?

Frequently Asked Questions

Can I change what I invest in after I open the account?

Yes. You can sell one investment and buy another inside the Roth IRA without tax consequences. The account itself is tax-sheltered, so trades inside it do not trigger capital gains tax. You can rebalance, switch from individual stocks to a fund, or move everything to a target-date fund whenever you want.

What if I do not know anything about investing?

Start with a target-date fund or a simple three-fund portfolio of index funds (U.S. stocks, international stocks, bonds). Both require almost no knowledge and perform better than most people who try to pick individual stocks. Your brokerage's website usually has educational resources, and you can also read the fund prospectus to understand what you own.

Should I invest in individual stocks or a fund?

Most people do better with a fund. Individual stocks require research, monitoring, and rebalancing, and studies show that most individual investors underperform a simple index fund. Pick individual stocks only if you have strong knowledge of specific companies and enjoy the work.

Do I have to invest the money right away?

No. You can deposit money into a Roth IRA and hold it in cash or a money market fund while you decide. However, cash earns very little interest, so sitting in cash for years costs you growth. If you are unsure what to buy, a target-date fund is a reasonable default while you learn more.

What fees should I expect to pay?

Index funds and ETFs typically charge 0.03% to 0.20% per year in expense ratios. Target-date funds usually charge 0.10% to 0.20%. Some brokerages charge per trade or per fund, while others charge nothing. Compare the total cost—expense ratio plus any account fees—before you choose a custodian.
