Shares of the Indian Energy Exchange (IEX) fell 18% in two trading sessions due to the Ministry of Power's directions to initiate a market coupling process. This could make prices uniform across platforms, which could reduce the role of energy exchanges. The government entity will make the price discovery, and the exchanges will only serve as an aggregation platform. Analysts advise investors to avoid the stock until the coupling issue is clarified. Market coupling means that a government entity will make the price discovery based on which power will be dispatched on platforms like IEX.
