Tata Chemicals is among the top five gainers on the BSE since the opening bell. The stock opened at the same levels as yesterday, at Rs.315 and it rose almost 8% to an intraday high at Rs.339.95.

The stock from today has started trading without its food & beverages business. The stock turned ex-date on Wednesday as it completed the demerger process.

From today, Tata Chemicals' consumer products segment has been demerged into Tata Global, which is renamed as Tata Consumer Products.

Tata Chemicals shareholders will receive 1.14 shares of Tata Global for each share held in the company. Investors wishing to receive Tata Global shares should have bought the shares of Tata Chemicals shares yesterday.
