ITC's shares rose up by 0.41% after reports that its largest shareholder, BAT, is planning to sell a portion of its stake. This would reduce BAT's shareholding from 29.03% to 25.03%, worth around Rs 20,320 crore. However, the sale may face regulatory hurdles due to restrictions on FDI in tobacco companies. Jefferies downgraded ITC's stock due to potential challenges faced by BAT.
