Short-seller Jim Chanos reiterated his bearish SolarCity outlook on Thursday, despite the stock closing more than 6 percent higher. But Chanos—and some "Fast Money" traders—believe the wider solar space holds long-term upside.
Chanos told CNBC he would add to his bet against SolarCity if it were easier to do, but stressed that he is not bearish on solar overall. While he would not short the stock, trader Tim Seymour noted he "certainly wouldn't be getting long here."
First Solar has blown past the broader market this year, climbing more than 44 percent. Some investors may start to reduce their exposure to the company and bet on other solar names, said trader Steve Grasso.
