A US regulatory probe into accounting practices of the Asian e-Commerce giant has hit its share price.

Shares in Chinese e-commerce giant Alibaba, which provides a range of services including wealth management, fell by almost 7 per cent yesterday after it disclosed it was being probed by the US Securities and Exchange Commission over accounting practices.

The SEC is examining a report from the company's "Singles' Day" promotion, its largest shopping day, and how it consolidates its results, the firm said in its annual report.

Alibaba is listed on the New York Stock Exchange; its shares fell about 22 per cent during 2015 amid concerns about China's economy. Alibaba's 2014 IPO, worth around $25 billion, is the largest in modern financial history and one of the most significant liquidity events of modern times.
