The S&P 500 moved 0.9% higher, logging its first positive trading day since jumping to an all-time closing high last Thursday.

Shares of solar technology company Enphase Energy (ENPH) led the S&P 500 higher, soaring 9.6%. Heading into Wednesday's session, Enphase shares were down roughly 18% year to date amid sluggish demand for solar equipment. However, the company expects demand to recover in Europe during the later part of the year, and it could see a boost from its energy monitoring and distribution services.

Enphase was not the only bright spot in the solar industry. Shares of photovoltaic (PV) solar solutions provider First Solar (FSLR) jumped 9.3%. First Solar faces similar headwinds related to high interest rates and slumping demand and the company is positioned to benefit from tax credits.

Cintas (CTAS) shares added 8.3% after the provider of workplace equipment and cleaning supplies reported better-than-expected quarterly results and boosted its full-year guidance.

Shares of Albemarle (ALB), the world's largest lithium producer, advanced 8.2% following news that Chile's government has opened additional lithium-rich salt flats to private investment. The South American country is home to the second-largest lithium industry in the world after Australia.
