Intel's stock surge driven by turnaround optimism and potential major customer wins (Tesla, Apple) validates the company's foundry strategy and justifies aggressive capital spending.

"Its foundry unit has won Tesla as a 14A customer and optimism for another marquee client grew after U.S. President Donald Trump said Apple would make processors with Intel. As of last close, the stock has nearly tripled this year, outperforming rivals AMD and Nvidia and the Philadelphia Semiconductor Index's nearly 75% rise."
