Plug Power (PLUG) - Get Report got a downgrade from J.P. Morgan analyst Paul Coster, who said that the stock was fully valued.
Coster said Plug Power is a "first- and fast-mover in the hydrogen fuel cell space with proven technology to pursue a massive market opportunity," and could grow sales to more than $1.2 billion by 2024. "This is our top pick in the hydrogen space, but [the stock is] fully-valued in our view."
