Why Plug Power Stock Surged 26% in May But Is Falling Apart Again
Overview
May was a significant month for Plug Power (NASDAQ: PLUG) as the hydrogen fuel-cell maker achieved something investors have been waiting to see for several years: its first glimpse of profitability. Shares surged after earnings, ending the month up 26.2%, according to data provided by S&P Global Market Intelligence. Although Plug Power has cooled off since then and given up much of those May gains, the stock is still up roughly 60% for the year, as of this writing.
