Singles\u2019 Day is set to break all kinds of international sales records this year. But don\u2019t expect the frenzy to lift Alibaba chairman Jack Ma\u2019s net worth. Once the richest person in Asia, Ma controls a $37.4 billion fortune, according to the Bloomberg Billionaires Index. The Alibaba tycoon\u2019s wealth has dropped 17.6 percent this year, mostly dragged down by the company\u2019s slumping shares. India\u2019s Mukesh Ambani took over to top spot in the region in July. Singles\u2019 Day has ballooned into world\u2019s biggest shopping phenomenon, generating $25.3 billion in sales last year. The number is sure to grow this year since the company is including sales from its Southeast Asia arm Lazada. But Alibaba shares rarely benefit from all the hype. The stock fell on or after every Singles\u2019 Day since 2014. Ma said in September that he\u2019s stepping down as chairman of the company\u2019s board in 12 months. Ma will leave the board in 2020.
