Solar stocks are trades, not investments, because the industry is a perennial long-term loser despite the continued growth of solar power. As Warren Buffett said of airlines, the urge to invest should be resisted no matter how attractive Enphase, Sunrun, First Solar, SolarEdge, Nextracker, Array Technologies, Canadian Solar or even a broad solar ETF may look. That holds even as @optionscjp notes Enphase is turning toward commercial data center projects. x.comÂ
