TOKYO—The Tokyo Stock Exchange inaugurated its new top-tier Prime section on Monday, and all the familiar names were present, Toyota, Sony, Honda and the like.

And then there was Econach Holdings Co. , which has 13 full-time employees and hasn’t paid a dividend since 1969. The company owns Thermae-yu, a bath and spa in a Tokyo red-light district that features a massage parlor, a pub and all-night service.

It is no insult to say that Econach operates at some distance from the stock exchange’s aim that Prime companies “center their business on constructive dialogue with global investors” and serve as “investment instruments for many institutional investors.” The bathhouse’s top-tier ranking can be chalked up, in part, to Japan’s respect for the venerable, an area in which Econach excels. Its history dates to 1926. 

Elon Musk disclosed a 9% stake in Twitter Inc., turning one of the social-media company’s most famous users into its largest shareholder.

The surprise move sent Twitter’s stock up 25% in Monday trading, though little is known about Mr. Musk’s intentions. The Tesla Inc. chief executive has previously reveled in the attention from his more than 80 million Twitter followers, and criticized the service broadly.

In a securities filing Monday, Mr. Musk reported owning almost 73.5 million shares of Twitter as of March 14, representing a stake valued at $2.9 billion based on Friday’s closing price. That gives Mr. Musk more Twitter shares than even company co-founder and former CEO Jack Dorsey, as well as large investors such as the Vanguard Group Inc.

Stuart Williams, a voice actor, took his seat behind a microphone at a sound studio in Manhattan one cold day early this month. On a screen in front of him played a steamy love scene from the second season of “Bridgerton,” the hit romantic streaming series set in Regency-era London.

“He lies behind her, gently moving his hand between her thighs. Their lips remain pressed together as he shifts to lie over her, supporting his weight on his powerful arms,” Mr. Williams intoned in his crisp English accent. He went on to describe what else Viscount Anthony Bridgerton did with his hands and what his lover did in response.

After recording the take, Mr. Williams blushed deep red.

“It does feel sometimes like I’m reading from one of those grocery store smut novels with Fabio on the cover,” he says.

Warren Bischoff, who leads a group of financial advisers in the Washington, D.C., area, has taken on a new role since returning to the office a few months ago. He’s the dress-code police.

In a single week, he had to tell one employee that white tennis sneakers are a no-no, another that bluejeans aren’t appropriate, and a third that T-shirts will never fly. In a recent edge-case ruling, he decided that “dress sneakers”—brown shoes with a white sole—might be OK, but only on Fridays.

“They have a foot in both camps,” he says. “They’re very tricky.”

Last fall I reported on a phenomenon that doctors around the globe were just beginning to understand: Teen girls were showing up in hospitals and clinics with sudden motor and verbal tics seemingly related to videos they watched on TikTok.

Doctors say they’re continuing to see an outsize number of girls suffering from tics, and some are also developing new disorders.New research findings offer hope that the problems can be addressed.

Starting back in the spring of 2020, girls in Chicago were uncontrollably blurting out the same words as girls in Calgary. Doctors from the U.S. to the U.K. discovered that many of the teens had been watching TikTok videos of people who said they had Tourette syndrome, a nervous-system disorder that typically strikes males during early childhood and causes them to make repetitive, involuntary movements or sounds.

Armed with a slim laptop and a Wi-Fi hot spot, Bobbie Carlton used to work everywhere—coffee shops, clients’ offices. The 56-year-old, who runs an online speakers’ platform, felt like the archetype of the modern worker. “Cords are for old people,” she explained.

Now 50 feet of Ethernet cable snakes through her 100-year-old house in Lexington, Mass., climbing over doorways, running up the staircase, taped to the floor of the upstairs hall. It’s seriously ugly, she acknowledges.

“Good God, this is, like, me in the ’80s,” she says.

And yet, she loves it. 

“I’m sitting down, and I’m plugging in,” she says.
