Shares across Adani Group companies experienced a significant drop on Tuesday following a Wall Street Journal investigation that revealed the US Department of Justice is reviewing potential transactions between the Indian conglomerate and US-sanctioned Iran. The report ignited a sharp sell-off led by Adani Ports & Special Economic Zone Ltd. $ADANIPORTS.NS, whose shares tumbled by as much as 2.7%. This marked the steepest single-day loss in over three weeks for the major infrastructure stock. In total, nine of ten Adani-affiliated securities ended the session in negative territory, signaling broad-based investor anxiety.
