Shanghai Electric's stock plummeted 8.14% during intraday trading, reflecting significant selling pressure after a period of sustained gains. The sharp decline occurred as investors took profits following the stock's consecutive rally in previous sessions.

The sell-off was driven by multiple factors including profit-taking pressure that accumulated after the stock surged from earlier catalysts in the controlled nuclear fusion sector, thorium molten salt reactor concept, and gas turbine business developments. Additionally, the broader Heavy Electrical Equipment sector experienced a correction, with peers also facing downward pressure during the session.

Market sentiment was further influenced by the company's recent announcement regarding the transfer of its 47.4% stake in subsidiary Shanghai Electric Guoxuan New Energy, which has received mixed interpretation from investors regarding the implications of this asset disposal.
