Exchange Investigation and Pending Responses

According to NSE India (National Stock Exchange), Akanksha Power and Infrastructure Limited's share price saw significant gains or declines, after which the exchange sent a letter to the company requesting the latest relevant information. The company’s response is awaited.

Similarly, Premier Polyfilm Limited recorded a notable increase in trading volume, and the exchange has asked the company for details to protect investors’ interests. In the case of ONGC, media reports mentioned that a U.S. license was granted to fully resume operations in Venezuela and that operator status was being monitored. To verify the accuracy of these reports, the exchange wrote to the company, and a response is still pending.

Regarding Reliance Industries, media reported that the Supreme Court imposed a penalty of Rs 1 million for delays in the NTPC gas supply lawsuit. To verify this report, the exchange sought clarification from the company, and a response has not yet been received.

In the case of Tarmat Limited, after a significant price change, the exchange sent a letter to the company on August 14, 2026, and its clarification is also available on the website.
