<div id="readability-page-1">FuelCell Energy Inc ( FCEL ) shares are trading sharply lower on Monday. The stock fell roughly 20% in early trading, erasing a significant portion of its recent massive gains. The Nasdaq is down 0.81% while the S&amp;P 500 has shed 0.41%. • FuelCell Energy stock is taking a hit today. Why is FCEL stock dropping? <h2>Retail Traders Pivot To Profit-Taking</h2> The primary driver behind Monday's decline appears to be aggressive profit-taking. FuelCell Energy ( FCEL ) stock previously hit a 52-week high of $22.83. The peak capped a multi-day surge. The stock climbed over 100% in the last month alone. Retail traders are now securing gains after this rapid price appreciation. <h2>AI Data Center Euphoria Cools</h2> The intense momentum in the clean energy sector is taking a breather today. Market optimism recently shifted into high gear following a landmark power deal. Bloom Energy Corp ( BE ) signed a master agreement with Oracle Corp ( ORCL ) last month. That deal supports up to 2.8 gigawatts of capacity. However, enthusiasm for AI power trade is cooling off this week. <h2>FCEL Technical Levels To Watch During Pullback</h2> FCEL remains in a strong longer-term uptrend, trading 25.5% above its 20-day SMA ($13.76) and more than doubling its distance above the 200-day SMA ($7.93). Momentum is the bigger story: RSI is at 81.43, which signals the move has been stretched and can be prone to pullbacks even if the primary trend stays intact. From a structure standpoint, the bullish backdrop is still there with the 20-day SMA above the 50-day SMA, and the golden cross that formed in October 2025 still frames the longer trend as constructive. FCEL Price Action: FuelCell Energy ( FCEL ) shares were down 20.88% at $16.89 at the time of publication on Monday, according to Benzinga Pro. Over the past month, FuelCell has gained about 100.92% versus a 3.9% rise in the S&amp;P 500 and is up roughly 137% year-to-date compared to the index’s 7.4% gain.
