Tesla Shares Surge 7.6% on UBS Upgrade, AI Chip Progress

Tesla shares surged 7.6 percent on April 15, 2026, closing at 392.04 after a volatile session that capped a 14.2 percent weekly gain. The rally, which pushed the stock to an intraday high of 394.65, followed an upgrade from UBS analysts and an announcement from Chief Executive Elon Musk about progress on the company's next-generation AI chip.

The uptick came amid broader market optimism, with the S&P 500 rising 0.2 percent and the Nasdaq Composite advancing 0.5 percent, buoyed by signs of de-escalating tensions in the Middle East. For Tesla, specific catalysts included UBS elevating its rating on the stock from sell to hold, with a price target of 352. Analyst Joseph Spak noted that current valuation levels better balance near-term risks, such as softening electric vehicle demand and elevated capital spending, against long-term opportunities in artificial intelligence and autonomy. "There will ultimately be meaningful progress in the robotaxi and Optimus fields," Spak said, positioning Tesla as a leader in physical AI.
