Alibaba is reportedly considering a $5 billion convertible bond sale, according to Bloomberg. The Chinese e-commerce giant's Hong Kong shares dropped 5.8% as of 3:50 p.m. following the news, with an intraday drop of 5%. The funds raised would be used to support share repurchases and boost growth. This move comes shortly after JD.com’s recent $1.75 billion convertible bond offering.
