A rally that lasted two years has given way to one of the steepest drops in recent memory. And investors in China are feeling the pain.
Chinese tech stocks have lost about $480 billion in market value in less than four months, as worries over lofty valuations, demand for artificial intelligence and export restrictions collide with renewed market turmoil.
How far have Chinese tech stocks fallen?
The Shanghai STAR 50 Index, which tracks major technology and semiconductor companies, has dropped about 40% over that period, reversing a rally fueled by government support for the tech sector. The STAR Market was launched in 2019 to help Chinese technology companies raise money at home, often described as China’s answer to the Nasdaq.
On Tuesday, Oct. 27, 2026, the index fell 4.81% as Chinese tech stocks led a broad decline, with more than 4,900 stocks across China’s markets falling.
The broader CSI 300 Index, which tracks the largest companies listed in Shanghai and Shenzhen, has fallen about 20% from its June peak, a drop that meets the common definition of a bear market. Selling has spread well beyond the tech sector.
Why are Chinese tech stocks dropping?
Investors have grown concerned that Chinese tech stocks climbed too high during the rally, particularly companies tied to artificial intelligence.
AI companies made up 42% of China’s stock market value before the decline and accounted for 57% of trading in shares listed in China and Hong Kong, according to Goldman Sachs data. Goldman Sachs is one of several global banks that have tracked the AI boom in Chinese markets.
That heavy concentration means doubts about AI demand can ripple across the entire market. U.S. export restrictions on advanced chips have added pressure by limiting Chinese companies’ access to key technology. Chinese companies have raced to develop homegrown chips and AI models to reduce their reliance on American technology.
How does this compare with U.S. tech stocks?
The losses in Chinese tech stocks stand in contrast to a relatively modest pullback in American technology shares. American tech giants have also faced questions about AI spending, but their shares have held up better.
The decline raises questions about Beijing’s push to move household savings out of bank deposits and real estate and into stocks, part of an effort to build a steadier rising market. Officials have urged pension funds and insurers to invest more in stocks.
Many Chinese families have long kept their wealth in property, which has struggled in recent years amid a prolonged housing downturn. A falling stock market could make households even more cautious about spending.
What role does the Communist Party meeting play?
The slide comes during a leadership meeting of the Chinese Communist Party held over four days, Oct. 26 to Oct. 29, in Beijing.
Officials at the meeting are focusing on party discipline and internal governance, even as China faces economic challenges including weak consumer spending and the housing slump. Such meetings typically set broad policy direction rather than announce specific economic measures.
Markets often watch such meetings closely for signs of new economic support, and the lack of clear stimulus signals may be weighing on investor confidence.
What comes next for Chinese tech stocks?
Analysts will watch whether Beijing steps in to stabilize the market, as it has during past downturns, through measures such as purchases by state funds. State investors, sometimes called the national team, have bought shares to steady prices in previous slumps.
For now, the steep drop in Chinese tech stocks shows how quickly enthusiasm around AI can turn when investors start questioning values. How Beijing responds could shape the market’s direction into next year.
