Did you panic sell during this week's market volatility? Here’s when to get back into the stock market

You’re not alone if you panic sold during this week’s stock market volatility and you’re feeling regret, experts say.

Russia’s invasion of Ukraine triggered U.S. stock market swings on Thursday, with the S&P 500 dropping by as much as 2.6% before closing 1.5% higher. The Nasdaq Composite recovered from a nearly 3.5% decline, rising by around 3.3% the same session.

While some investors seek opportunities amid the turmoil, others retreat by selling off assets. However, getting back into the market after panic selling can be an issue, according to research from the Massachusetts Institute of Technology.

While the research didn’t examine why certain investors are more prone to impulsive sell-offs, they found an alarming trend: Many panic sellers don’t reinvest after going to cash.

More than 30% of investors who panic-sold assets after previous downturns never got back into the stock market, as of Dec. 31, 2015, the MIT research paper found.

It’s a problem because those who leave the stock market and don’t re-enter miss out on the recovery. In fact, the best returns may follow some of the biggest dips, according to research from Bank of America.

Since 1930, missing the S&P 500’s 10 best-performing days every decade led to a total return of 28%. However, someone who stayed invested through the ups and downs may have a 17,715% return, the company found.

“The worst thing that you can do is let the mistake of selling at the wrong time hold you back from participating in some of the gains in the future,” said certified financial planner Jake Northrup, founder of Experience Your Wealth in Bristol, Rhode Island.

Before reentering the stock market, experts say, it’s essential to explore the reasons that the panic sale may have happened.

First, panic sellers may want to reflect on the event, their thought process, feelings and what they can learn from it, said Northrup.

“Diving a little bit deeper, was it the volatility that really impacted you?” he asked. “If so, maybe take a harder look at your risk tolerance.” 

For example, if someone can’t stomach market swings, they may want to reconsider their asset allocation, perhaps pivoting to less stock exposure, depending on their situation, he said. 

But they need to ask themselves if there’s been a change in their core values, goals and reasons for investing. If the answer is no, they may not need to shift their strategy, Northrup said.

Someone who panic sells may also have a near-term need, which may have amplified their fear, said Teresa Bailey, a CFP and senior wealth strategist at Waddell & Associates in Nashville, Tennessee.

While getting back into the market may pay off long-term, experts say panic sellers often feel anxious about when to reinvest.

“You have to be right twice,” said Bailey, as it’s difficult to know when to sell and reenter the market.

“Typically, emotion is amplified around getting back in because you don’t want to make a second mistake,” she said.

Some panic sellers wait for assets to decline again before reentering, which may only extend their time out of the market, Bailey said. However, if they cashed out based on a short-term news event, it’s important to jump back in. 

The most common strategy is dollar-cost averaging, where someone puts their money back to work by investing at set intervals over time.

While research shows investing a lump sum sooner may offer higher returns, dollar-cost averaging may help prevent emotional reinvestment decisions.

“If someone has panic sold, they might have a tendency to be very emotional with investing,” Northrup said.

“It can be really challenging if someone is scarred from some of the volatility and then missing out on some of the gains they could have had,” he said.

Investors may also combine dollar-cost averaging with a lump-sum approach, Bailey said, which may need professional guidance.

For example, they may reinvest every week for eight to 10 weeks and deploy a larger amount if the market dips during that period, she said.

The tactic may allow someone to speed up their timeline to reinvest and get back in at a lower point.

But regardless of the strategy, it’s important to try to learn from previous mistakes and stick with the long-term investing plan.

“Over time, data shows if you stay invested your pot of money will grow,” Bailey said.
