His Top Glove Corp Bhd grew bigger than Malaysia’s banks, telecommunications firms and even the state-owned electricity company during the Covid-19 pandemic. Its share price soared 450% through the first seven months of 2020, leaving high-flyers like Moderna Inc, Zoom Video Communications Inc, Peloton Interactive Inc and Carvana Co in the dust and making Lim a billionaire several times over.
