Indian stock markets are seeing significant activity across various sectors, prompting investors to keep a close watch on key players. Several factors, including promoter stake sales, joint ventures, capacity expansions, and financial results, are influencing market sentiment.

IndiGo: Rakesh Gangwal and the Chinkerpoo Family Trust are set to divest a 3.1% stake in InterGlobe Aviation, the parent company of IndiGo. The block deal, valued at approximately ₹7,027.7 crore, involves up to 1.21 crore equity shares with a floor price of ₹5,808 per share, a 4% discount to the stock's closing price on Tuesday. This transaction is expected to occur on Thursday. This sale continues a phased dilution that began after an announcement in 2022 to exit the airline. Rakesh Gangwal has been selling his stake in the company since September 2022, after he and Rahul Bhatia, also a co-founder and promoter of the company, settled their dispute. After this stake sale, Gangwal and family will not be able to sell another IndiGo stake for 150 days. Despite these stake sales, IndiGo's stock price has seen substantial growth, more than tripling from ₹1,807 on March 2, 2022, to a recent close of ₹6,045. IndiGo expects early double-digit ASK (Available Seat Kilometers) rise in FY26. The company had 439 planes of which 50 are grounded and in FY26, about 50 new planes are likely to be added. The airline further expects the international segment to be its major growth driver over the next five years and sees 40% of its FY30 ASK from the international segment, up from 28% in FY25F.

The company is projected to announce a significant year-on-year increase in Q1FY26 profitability, driven by improved margins in its India business due to higher steel prices and lower coking coal costs. Domestic hot-rolled coil (HRC) prices in China have climbed 8% over the past month, driven by expectations of production cuts under Beijing's “anti-involution” policy and a $167 billion stimulus-backed hydropower project.
