Alibaba's earnings worry investors
Shares in Alibaba have plunged almost 9% after the Chinese e-commerce giant's quarterly earnings report showed weaker-than-expected sales growth.
The online shopping platform posted a 40% jump in sales to $4.2bn, but investors were hoping for more.
Alibaba was also recently reprimanded by a Chinese regulator, which accused the company of having lax controls over vendors.
