The pandemic profit boom for medical gloves and protective suit maker Ansell that helped the group declare a record final dividend on Tuesday may have passed its peak.

Soaring shipping costs, temporary shutdowns of some factories in Asia and an oversupply of single-use gloves at the lower end of the market are crimping the outlook. They triggered the biggest intra-day fall in the company’s shares since last November, with the stock tumbling 9 per cent to $36.85 in early trading on Tuesday. Just before the close, the shares were down 9.8 per cent.
