Fuel cell stocks pull back sharply after strong gains, led by FuelCell Energy's 10% drop.

Fuel cell stocks, including FuelCell Energy, Plug Power, and Bloom Energy, declined sharply midweek following significant gains over the past year. FuelCell Energy led the drop with a 10% fall, reflecting profit-taking after an 85% rise in the last month and concerns over its fundamentals and cautious analyst ratings. Bloom Energy showed more resilience due to strong recent revenue growth and raised guidance, while Plug Power's pullback aligns with ongoing unprofitability despite margin improvements. Investors should watch upcoming earnings reports and sector dynamics as volatility and speculative risks remain high in this group.
