Goldman Sachs has cut its target price for Vodafone Idea Ltd. significantly, warning of a potential 83% decrease in market value. Despite positive factors such as a recent capital raise, the brokerage firm maintains a 'sell' rating on the company. With forecasted losses in market share and looming AGR and spectrum dues, Goldman Sachs anticipates negative cash flow until at least fiscal 2031. Additionally, even in a best-case scenario, the firm expects Vodafone Idea's market share to remain low compared to its competitors.
