Plug Power (PLUG) shares surged 20% in premarket trading on October 6, 2025, following a 35% rise the previous day. The stock's rally was fueled by analyst upgrades, including H.C. Wainwright's price target increase to $7 per share and a reaffirmed buy rating from Craig-Hallum. Operational improvements, such as record production at its Georgia hydrogen facility and cost-cutting measures, also contributed to the positive momentum. Despite the recent gains, Plug Power reported a $227 million net loss in the last quarter, highlighting ongoing profitability challenges. The stock's 14-day RSI of 83 indicates overbought conditions, suggesting potential caution for investors.
