What Bankers Say You Should (and Shouldn’t) Do When Markets Crash

On days like Monday’s dramatic selloff, which capped a three-week loss of $6.4 trillion in global wealth, personal finance experts usually have the same advice for wary retail investors:

Take a breath. Don’t overreact. Take a moment to assess your portfolio. And depending on your situation, perhaps it’s time to put some new money in.

Still, it’s important to try to understand what’s happening, and why. Because times like these, when stock markets around the globe fall sharply, are bound to come again. There’s typically a drop of 10% or more every couple of years, and a slump of 25% or more every seven years, according to Zhu Hann Ng, founder and chief executive officer of Tradeview Capital, a fund manager in Kuala Lumpur.

“It’s a good lesson, and a wake-up call, to realize that irrational exuberance doesn’t keep going,” Hann said.

In recent days, financial markets have shifted from confident to fearful as grim milestones piled up: SoftBank Group Corp. shares plunged the most since going public in 1998 on Monday. Japan’s Topix tumbled 12%, its worst day since 1987. Taiwan’s benchmark stock index plunged by a record. Bets on AI and computer chips, recently seen as surefire, were upended. Meanwhile, the US economy seemed to wobble.

As markets rebounded on Tuesday experts attributed Monday’s meltdown to an overreaction, even as many investors still grappled with painful losses.

It can be hard to make sense of it all.

What just happened?

People and institutions have been betting big on different assets, including big tech companies making forays into AI. When things shift, like the outlook for the US economy worsening or the Bank of Japan moving to hike interest rates, positions must be shifted and some need to sell. Selling tends to beget more selling, especially when uncertainty swirls about matters like the upcoming US election or tensions in the Middle East.

“It is hard to know what the stress point for the selloff was,” said Rob Almeida, global investment strategist and portfolio manager at Boston-based MFS Investment Management. In effect, many investors had made big bets using borrowed money, he said, and many tried to exit at the same time.
