3 reasons to invest in stocks

Key takeaways

  • Cash and short-term investments do play an important role in your financial plan but having too much in cash can be surprisingly risky over the long term.
  • Cash offers relatively little growth potential, so you may lose purchasing power to inflation, and run the risk of falling short of your goals.
  • Stocks have historically offered more growth potential than cash or bonds, helping investors reach their goals and manage inflation.
  • A diversified mix of investments like stocks, bonds, and short-term investments can help you target the level of risk you feel comfortable with, providing some growth potential with less volatility than investing in just stocks.
  • Financial professionals can help you create a financial plan that fits your needs and could help you reach your goals.

For investors who are unsure about the stock market, cash and short-term investments can provide orderly and routine returns that feel safe and predictable. But there can be some downsides if they make up the majority or entirety of your long-term investment mix.

"Sometimes investing successfully can feel counterintuitive," says Naveen Malwal, CFA, institutional portfolio manager with Fidelity's Strategic Advisers. “I can understand why the volatility of the stock market may lead some investors to feel stocks may be risky. However, investors who focus on the growth potential of stocks, not just the downside, often reach their financial goals more easily than they would if they were investing mostly in cash.”

Here are 3 potential benefits of investing in stocks, bonds, and other investments that can provide growth potential—plus 2 ways to do that confidently and help reach your goals.

1. Your money may grow more quickly

High-yield savings accounts and safe investments like money market funds trade yield for stability. While your account value won't generally go down due to events outside your control, it may not go up very much over time either.

"Looking back historically, investing in short-term investments has been OK for investors, but nowhere near as good as in stocks, or a combination stocks, bonds, and cash. Diversifying away from cash has generally led to stronger returns for investors, which means they have often reached their financial goals more easily," Malwal says.

The chart shows the potential benefit of investing for growth by comparing how $100 would have grown since 1980 if it grew at the same rate as inflation, 3-month Treasurys, bonds, or the S&P 500 Index. At the end of 2023, $100 would have grown to 13,665 in the stock index compared to 660 in Treasurys or 1,756 in bonds.

Actual historical data were used to compute the growth of $100 invested in these portfolios for the period between Jan. 1, 1980 and Dec. 29, 2023. Stocks, bonds, and short-term investments are represented by total returns of the S&P 500 Index, Barclays Aggregate Bond Index, 3-month Treasury Bills. Past performance is no guarantee of future results.

2. You can fight inflation and help maintain purchasing power

Inflation is something that everyone has experienced, particularly in recent years. It's hard to miss that your money doesn't go as far as it used to—your usual purchases like groceries and prescriptions may be taking up a bigger chunk of your paycheck or savings than they used to.

Earning a rate of return higher than the rate of inflation can help ensure that you're able to continue to afford the things you want to buy. Unfortunately, "the return on short-term investments over the long run has barely kept up with inflation, so it's hard to stay ahead, especially when inflation is surprisingly high—as it was just a couple of years ago," says Malwal.

A related risk of staying in relatively safer areas like savings accounts, Treasurys, and CDs can be reinvestment risk. When the Federal Reserve raises interest rates, savers can benefit as yields rise. But when the Fed lowers interest rates, the yield on safer investments tends to go down. So it can be hard to replace a maturing investment with another one with the same risk and return.

For example, let's say you buy a 3-year CD today with a 5% annual percentage yield (APY). Then over the 3-year term, interest rates fall. When your CD matures and you want to buy another one, you may have to accept lower yields or buy a longer-term CD. There's no guarantee that you will be able to reinvest your money at the same level of risk and receive the same level of return in the future.

"If the return on a short-term investment decreases, for example from 5% to 4%, due to declining interest rates, an investor can have a harder time staying ahead of inflation," says Malwal.

3. You may have a better shot at reaching your goals

Retirement is one big goal most people have, but there are myriad other goals that you may be working toward: a dream vacation, a wedding, a big party, a new car, remodeling the kitchen, and so on. If there are several years until your goal, investing for more growth potential could potentially help you successfully reach or exceed your goal.

"By investing in a more diverse mix of stocks and bonds and short-term investments, the investor has a higher chance of achieving their goal, potentially with a couple of added benefits. With a higher rate of return, they may reach their goal quicker. And, once they actually reach the end of their time frame, they could have more money than they otherwise would have. The possibility of having more to spend in the future would be a potential benefit that the saver could miss out on compared to a cash investor," says Malwal.

More than 1 in 10 retirement investors has an investment mix that Fidelity would consider too conservative for their time frame.1,2 A little extra return could potentially improve their chances of maintaining their lifestyle in retirement.

Comparing the potential growth of a basic savings account with a conservative investment mix shows the potential benefits of investing. Investing $100,000 in a savings account over 10 years could lead to $602 of growth versus the conservative investment mix, which could return $63,978.
Estimates are based on historical returns. A conservative Investing mix is based on 20% stocks, 50% bonds, 30% short term investments. Past performance is not indicative of future results. Investing involved risk, including the risk of loss. The investment strategies presented here have different fees, guarantees and risk, and you should carefully consider these prior to investing. Please see footnote 3 for additional important information.

Diversification may be a better way to manage investment risk

There's no perfect investment that offers the best of all worlds—low risk and high returns. But there is a way to take advantage of the many different patterns of investment risk and return: diversification.

Diversification can be a helpful strategy because different types of investments offer varying levels of risk and return. Some types of investments may outperform during economic downturns while others shine brightest during boom times. Some investments may do well as interest rates rise while others get a boost from low interest rates.

The goal of diversification is not necessarily to boost performance—it won't ensure gains or guarantee against losses. But diversification does have the potential to improve returns for whatever level of risk you choose to target.

A risk-averse investor could still invest in short-term investments like money market funds, CDs, and Treasurys with the addition of bonds and a small portion of equities. By mixing riskier investments with some relatively safer choices, they may be able to get a higher return while still keeping the risk of losing money low.

If you’re not sure how to do it yourself, there’s good news: Financial professionals can help you pick investments and balance the need for principal protection with the need for some growth potential. By determining an appropriate rate of return to target based on your financial situation, time frame, and comfort with risk—while accounting for inflation—professionals can work with you to determine what investments and strategies may fit your goals. And they can help in many more ways as well.

Risk versus return

This chart show the potential benefits and risks of investing. The average annual return of a conservative investment mix has historically been 5.78% versus 9.56% for an aggressive growth mix. The worst 12-month return for the conservative mix was -17.67% compared to -60.78% for aggressive growth.
Data source: Fidelity Investments and Morningstar Inc. 2023 (1926–2023).4 Past performance is no guarantee of future results. Returns include the reinvestment of dividends and other earnings. This chart is for illustrative purposes only. It is not possible to invest directly in an index. Time periods for best and worst returns are based on calendar year. For information on the indexes used to construct this table see Data Source in the notes below. The purpose of the target asset mixes is to show how target asset mixes may be created with different risk and return characteristics to help meet a participant's goals. You should choose your own investments based on your particular objectives and situation. Remember, you may change how your account is invested. Be sure to review your decisions periodically to make sure they are still consistent with your goals. You should also consider any investments you may have outside the plan when making your investment choices.

Financial professionals are here to help

Working with a trusted professional can help boost your confidence about your money and investing—a recent survey found that investor confidence about reaching their long-term goals increases significantly after working with a financial professional.5

Getting professional help can be affordable as well. For straightforward investment management, robo advisors can simplify the investment process. Fidelity’s robo advisor, Fidelity Go®, is a hybrid robo advisor. With a balance of $25,000 or more, you can speak on the phone with a professional for live, personalized coaching.

Your financial picture probably includes so much more than investments. Working with a professional can help you understand how all the pieces fit together by asking you about your personal and financial goals, and working with you to help answer questions such as:

  • Are your spending and cash flow appropriate?
  • What does financial protection mean to you, and how important is it?
  • What does growth mean to you, and how important is it?
  • Are your investments aligned with your preferences?
  • How will you manage your investment portfolio?

"As they discuss their situation with a financial professional, many investors learn about other opportunities, so it may turn out that they don't have to take that much more risk to get the benefit of a more diversified set of investments," Malwal says.

"Perhaps they do still want to keep most of their investments in a short-term space, but there's a smaller portion they would be willing to allocate to stocks and bonds. That combination may be enough for them to feel that their money is relatively secure, and they have a better chance of staying ahead of inflation and reaching a long-term goal," he says.

Knowing that you have options and that you've made an informed choice can help you feel more in control. While the stock market may go up and down more than most people would like, your investment mix doesn't have to be as volatile to provide growth potential. If you're not sure how to create a financial plan that includes an appropriate investment mix for your situation, consider working with a financial professional.

Age-appropriate asset allocation involves investing in a mix of stocks and fixed-income investments to align with one’s risk-tolerance, age, and time horizon. “Appropriate” refers to what Fidelity considers to be an appropriate mix, derived from data reported in the Retirement Savings Assessment about an individual’s equity allocation distribution that is placed into four categories, based on that person’s age. Those categories are “On track”: within 25 percent on target date equity allocation; “Aggressive”: an equity percentage more than 25 percent above the age-appropriate target equity; “Conservative”: an equity percentage less than 25 percent below the age-appropriate equity target; as well as a category for assets held in a Target Date Fund.

3. Methodology for investing returns example: Estimates derived using Fidelity Goal Booster. Estimates are based on past performance. Past performance does not predict future results. The timing of deposits and when you are looking to use the money can impact potential return as well as which savings or investment options may be right for you. Hypothetical models include the following assumptions:

  • The average market return corresponds to the 50th percentile of the returns. Conservative Investing mix is based on 20% stocks, 50% bonds, 30% short term investments. Estimated/Average return rates stay constant over the course of the goal timeframe
  • You won’t make any withdrawals from the account during the goal timeframe
  • No fees or taxes will be applied
  • Your starting amount and monthly contributions are invested in the model allocation in the stated time period
  • Investments in “traditional savings” and “locked savings” assumes only FDIC insured accounts or certificates of deposits are used

For investing returns, calculations are made by computing the 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10-year average annual returns based on monthly historical performance of stocks, bonds, and short-term instruments from 1926–2022, obtained from Ibbotson Associates. These are hypothetical and therefore past performance is no guarantee of future results. Returns include the reinvestment of dividends and other earnings. The assets are rebalanced monthly to the stated asset mix. Any chart is for illustrative purposes only and does not represent actual or implied performance of any investment option.

Savings returns are calculated using a national average savings account rate from FDIC. Locked rate savings returns are calculated using national average CD rates for 1-, 2- and 5-year CDs from BankRate. CDs are assumed to be purchased once and are not being rolled over upon maturity. When purchasing CDs from within a savings account, all additional monthly contributions into the savings account, as well as continuing savings with the proceeds of a CD after it matures, are assumed to be earning a national average saving account rate from FDIC.
