币界网报道:Plug Power, a penny stock trading under $1, surged 82% in a single day, sparking speculation about a potential 100% rally. The hydrogen fuel cell company, which has faced financial struggles and received a delisting warning from Nasdaq earlier this year, saw its shares jump following renewed investor interest in clean energy stocks. While the company continues to work on stabilizing its finances and expanding its hydrogen infrastructure, analysts remain cautious about its long-term viability. The sudden price surge highlights the volatile nature of penny stocks and the speculative trading surrounding emerging energy technologies.
