It was another bleak day for investors in Novo Nordisk as it said its obesity drug candidate CagriSema delivered up to 23 per cent weight loss over 84 weeks in a late-stage head-to-head trial, but failed to meet its primary endpoint against Eli Lilly’s Tirzepatide.

Software-related companies were also among the top decliners. The S&P 500 Software and Services index was down 3.8 per cent, extending its 23.5 per cent drop so far this year, as AI disruption fears rattled the sector.
