BEIJING (Reuters) – “Tragedy” – that was Alibaba Group Holding Ltd (BABA.N) founder Jack Ma’s prediction for the fate of rival JD.com Inc (JD.O) in comments published earlier this year. On Monday, Alibaba signaled it is no longer writing off its smaller competitor, making a $4.6 billion investment to give it more traction in two areas JD.com does well in: logistics and electronics. Ma’s online shopping titan bought into bricks-and-mortar electronics retailer Suning Commerce Group Co Ltd , surprising investors given it has traditionally stayed away from physical, offline assets.
