GQG Partners sells Adani Energy Solutions shares during India’s closing auction on Monday, and the added supply overwhelms expected buying from passive index-tracking funds. Traders cited by Economic Times say the stock falls about 10% on the day, with roughly $569 million worth of shares changing hands.

The reported timing is linked to the MSCI index rebalancing on Aug. 31, a period when hedge funds commonly build positions ahead of index changes and plan to sell into anticipated demand from passive investors. Multiple sources say the sales by GQG disrupted that “trade” by putting more shares into the market than some participants had expected. Bloomberg’s account focuses on the same mechanism, reporting that the sale overwhelms passive-fund demand and contributes to the day’s decline.

Economic Times adds details from an exchange filing, saying GQG’s stake is disclosed at 3.46% as of Aug. 31, down from 5.1% in June 2023, and that the filing was triggered after its Aug. 31 trades crossed a regulatory threshold. It does not specify how many shares were sold on Monday. A GQG representative declines comment, while an Adani Group spokesperson does not respond to an email request.
