On this episode of Stock Movers:

- Super Micro Computer (SMCI) is among leaders in a tech rally after President Trump said that China tariffs will drop if the two countries can reach a deal. Trump made his about-face on Tuesday, saying he’d be willing to “substantially” pare back his 145% tariffs on China. He turned down his aggressive rhetoric a day after meeting with executives from Walmart Inc., Home Depot Inc. and Target Corp., who said import taxes could disrupt supply chains and raise the prices of goods, according to people familiar with the matter. Warnings about the potential for empty store shelves within weeks seemed to resonate with Trump, one of the people said. Shares of Super Micro Computer rose as much as 11% in trading on Wednesday.

- Enphase Energy (ENPH) shares plunged to the lowest levels in almost five years after the solar and storage provider said it sees a 6%-to-8% hit to gross margins in the third quarter from steep US tariffs imposed by the Trump administration on battery imports from China. Ahead of that, the company expects a smaller impact of about 2% in the second quarter because of batteries imported before the higher duties were imposed, Chief Executive Officer Badri Kothandaraman said on a first-quarter earnings call.

- Tesla (TSLA) shares are soaring after Elon Musk vowed to pull back “significantly” from his work with the US government and pay more mind to Tesla Inc., assuaging investors concerned about the carmaker’s worst quarter in years. The chief executive officer will devote “far more” of his time to Tesla starting next month, saying during an earnings call Tuesday that his work establishing the so-called Department of Government Efficiency will be “mostly done.” Investors and analysts have increasingly called for Musk to refocus on the electric-car company, which is struggling under the weight of slumping sales and rising costs from President Donald Trump’s trade war. Protests have sprung up in recent months in a consumer backlash against Musk’s government work.
