Chinese regulators barred tutoring companies from making profits, a move that sent their shares plummeting on Monday, erasing tens of billions of dollars from the value of the country’s once blistering education sector, as Beijing turns its focus to the growing financial burden that students — and their parents — face.

Some of China’s biggest publicly listed education companies lost significant chunks of their value as investors ditched them after the announcement of rules that require all companies that offer curriculum tutoring to register as nonprofit institutions.

The rules, which were published over the weekend, will also restrict new foreign investment, once a key avenue for those companies to raise money. They are the latest in a series of moves by China to rein in its technology sector that has hit stocks of its biggest companies, in sectors as diverse as ride hailing and music licensing. Regulators say they are tackling privacy, cybersecurity and antitrust concerns, directing their crackdown at the country’s thriving internet industry.

Koolearn Technology, which provides online classes and test-preparation courses, said it expected the rules to “have material adverse impact” on its business. Its stock lost 33% on Monday. A handful of other Hong Kong-listed education companies, including New Oriental Education & Technology and Scholar Education Group, along with the U.S.-listed companies Gaotu Techedu and TAL, issued similar statements.

For years, China’s private education sector was one of the most enticing for global investors, who threw billions of dollars at publicly listed companies that promised to capitalize on the hundreds of thousands of families striving for better opportunities through education. By Monday evening in Asia, much of that money had vanished.

Many middle-class families in China pay for after-school tutoring to help their children gain an edge on national tests that determine their futures. Last week, the country’s top administrative body published an opinion that took aim at the sector and outlined its plans to “reduce the burden of students’ homework and off-campus training.”


Analysts swiftly recalibrated their assessment of the prospects for the industry, which was once valued at more than $100 billion by Wall Street banks like Goldman Sachs. On Monday, the bank’s analysts estimated it would be worth $24 billion in the coming years.

The news reverberated through Chinese stock indexes. The Shanghai Composite index closed 2.3% lower, and Hong Kong’s Hang Seng dropped 4.1%.

Separately, regulators over the weekend ordered Tencent, the Chinese tech conglomerate, to end all exclusive music licensing deals with record labels and fined it around $78,000 for what it said were unfair practices. Shares in Tencent Music, which trades in the United States, were also lower on Monday.
