Chinese e-commerce giant Alibaba Group Holding today reported a stronger-than-expected 32% rise in second-quarter revenue, despite the value of goods traded on its platforms growing at a slower pace. 

Revenue from mobile platforms, an increasingly important area for the company, nearly tripled to $1.66 billion.

Revenue rose to $3.49 billion in the three months ended September 30, beating the average analyst estimate of $3.44 billion, according to Thomson Reuters I/B/E/S. 

The jump in revenue added weight to Alibaba founder and executive chairman Jack Ma's recent comments that concerns about slowing consumption in China were overdone. 

The earnings report comes about two weeks before Alibaba's "Singles Day" shopping festival on November 11, which netted GMV of more than $9 billion last year. 

The company reported net income attributable to shareholders of $3.58 billion, or $1.40 per share. 

Excluding items, Alibaba earned 57 cents per share, beating the average estimate of 54 cents. 

Alibaba, facing increasing competition from rival, has been branching out from its core online shopping platforms in a bid to stem a slowdown in revenue growth. 

During the quarter, the company invested $4.6 billion in Suning Commerce Group in a bid to bolster its ability to compete in logistics and electronics - two areas of strength for
