Alibaba-affiliated (BABA.NYSE) Ant Financial Services Group launched an e-commerce tracking stock index Thursday as its finance division’s general manager announced the company’s online bank would launch in June, Reuters reported. The CSI Taojin Big Data 100 Index tracks e-commerce activities to gauge firms’ performances, pairing the company’s data troves with its aspiration to build an internet finance platform that will make services like banking, loans and credit, insurance, payment systems and investment open to more of China’s population. The online bank launch window comes after Tencent Holdings (0700.HKG) internet bank WeBank began trial operations in January of this year.
