Two state-owned investment firms — collectively known as China's 'national team' — carried out the share purchases :
Alongside them, the China Securities Regulatory Commission (CSRC) chaired by its chief convened a market stability symposium on Monday, July 20 .
Three coordinated actions stand out:
Direct share purchases: The two firms bought roughly 60 billion yuan (about $8.9 billion) of stocks over the weekend, with buying focused on state-owned enterprises and technology companies .
Regulatory symposium: On July 20, CSRC officials met representatives of listed companies, securities firms, and fund institutions. CSRC vowed to "make every effort" to maintain stable market operations and pledged to respond proactively to market concerns .
Further purchase pledges: Both state firms signaled they would continue additional purchases going forward .
Monday, July 20 (first trading day after intervention): The Shanghai Composite rose 0.85% to close at 3,796.3, while the CSI 300 gained 1.53%. However, the Shenzhen Component fell 0.71%, delivering a mixed performance .
Tuesday, July 21: Chinese shares posted a second consecutive day of gains, with the national team's continued buying and the CSRC's pledges supporting sentiment .
Wednesday, July 22: Markets showed signs of adjustment on profit-taking. The Shanghai Composite edged up just 0.07% to 3,867, while the Shenzhen Component dropped 1.42% and the tech-heavy ChiNext Index fell over 3% . The rebound proved short-lived, with technology stocks resuming their decline
.
The roughly $8.9 billion intervention stabilized markets temporarily — halting the rout and producing two days of gains — but the recovery was uneven and began to fade by the third session. Analysts described the move as a 'firebreak' rather than the start of a new bull market . Beijing's swift action demonstrated its willingness to use direct equity purchases to cap volatility, but it also underlined how fragile confidence remains in China's stock market, where government buying can slow a decline but cannot manufacture earnings or restore private investor sentiment on its own.
