Which Chinese stock exchange benchmark plunged nearly 9% on February 27, 2007?

The Shanghai Composite Index plunged 8.84 percent on February 27, 2007, in a sell-off that helped trigger a worldwide market wobble. The drop was the index's largest one-day percentage fall in a decade at that time.

Chinese authorities had been signaling concern about speculation, excessive lending and the rapid growth of share prices. Investors feared tighter measures to cool the market. The fall in Shanghai quickly affected stock exchanges in Europe and the Americas, although many markets later recovered.

This episode is often called the “China stock-market turbulence” of 2007. It was distinct from the much larger Chinese equity crash that began in 2015. The Shanghai Composite tracks prices of shares listed in Shanghai, including both renminbi-denominated A shares and foreign-currency B shares.
