Why Solar Stocks Fell Sharply on Monday

Key Takeaways

  • Stocks fell broadly across the solar-energy sector Monday, weighed down by a warning from SolarEdge.
  • FirstSolar was among the biggest decliners. Its shares had been lifted recently by optimism about the energy-generation needs of artificial intelligence.
  • Investors will get a look at FirstSolar’s next quarterly results on July 30.

Downbeat news from SolarEdge ( SEDG ) weighed on solar-energy shares Monday, with stocks falling across the sector.

FirstSolar ( FSLR ) stock, which had jumped in May amid enthusiasm for the sector’s prospects to provide the energy needed to power developments in artificial intelligence , fell 8.5% and was among the S&P 500’s biggest losers on the day. Its latest quarterly financial results are expected July 30.

Enphase Energy ( ENPH ) dropped more than 5%, while SunRun ( RUN ) tumbled 9%. The Invesco Solar Exchange-Traded Fund ( TAN ) fell nearly 6%.

SolarEdge, which warned of excess inventory and cut its staff, fell 15%. Its CEO said in a regulator filing cited a “current downturn in the solar industry,” highlighting particular weakness in Europe but more encouraging signs in North America.

The pullback in solar shares came as the S&P 500’s energy sector rose, lifted by shares of oil companies such as Chevron ( CVX ) and ExxonMobil ( XOM ).
