Shares of state-owned Coal India fell over 4 percent on Friday, October 30, despite the company reporting healthy earnings in the second quarter of the financial year 2026-27. While revenue growth remained strong in the reporting quarter, higher operating costs and weaker-than-expected EBITDA weighed on investor sentiment, prompting brokerages to flag concerns over near-term profitability. Coal India shares opened at Rs 398.30 and declined 4.4 percent to touch an intra-day low of Rs 380.70, on the BSE.
