FuelCell Energy is trading at $17.19, down 6.96%, with the immediate driver unclear.
- No verified October 5 company announcement or direct catalyst surfaced in the search.
- The October 2 hydrogen-stock rally was prior-session context, not an explanation for Monday’s decline.
- The S&P 500 and Nasdaq were slightly higher while the Dow was lower; a prior report linked fuel-cell declines to higher Treasury yields but did not establish today’s cause.
