Stocks took a steep dive on Monday amid fears that the coronavirus pandemic will be hard to pull out of.

The Dow Jones Industrial Average shed more than 700 points by mid-day. The S&P 500 is down 1.9%, and the Nasdaq Composite has lost 1.6%.

Despite the uncertain times, history has shown that the stock market gives more than it takes.

Between 1900 and 2017, the average annual return on stocks has been around 11%, according to calculations by Steve Hanke, a professor of applied economics at Johns Hopkins University in Baltimore. After adjusting for inflation, that average annual return is still 8%.

That’s why Rob Williams, vice president of financial planning at Charles Schwab, says that “for longer-term investors, we suggest staying the course if they can.”

In fact, if you want to reap the rewards of investing, you’ll have to sit through the losses.

Williams provided an example: Over the last 20 or so years, the S&P 500 produced an average annual return of around 6%. But if you missed the best 20 days in the market over that time span because you became convinced you should sell, and then reinvested later, your return would shrivel to 0.1%.

“Pain is a sign you’re investing well,” said Allan Roth, a certified financial planner and founder of Wealth Logic in Colorado Springs, Colorado.

That being said, there are some moves antsy investors can take.

For example, you’ll want to make sure you have enough cash reserves built up to cover any big upcoming expenses, including school tuition and planned vacations, said Milo Benningfield, a CFP and founding principal of Benningfield Financial Advisors in San Francisco.

“If not, consider raising cash from your portfolio now, rather than later after markets have fallen,” he said.

Meanwhile, older investors may want to tweak their portfolio to make sure they’re ready to exit the workforce, said Doug Bellfy, a CFP at Synergy Financial Planning in South Glastonbury, Connecticut.
