Micron Technology (MU) has emerged as a standout performer in the U.S. stock market's storage sector this year. Analyst @ai_9684xtpa posted on X that U.S. President Donald Trump purchased Micron shares around March, and his public endorsement on May 26, stating 'Micron is fantastic,' led to a 19% surge in MU's stock price, propelling it into the 'trillion-dollar market cap club.' Trump has previously expressed admiration for Micron in various public forums. While his endorsement played a role, the underlying factors likely include policy backing and support for the AI storage sector, where Micron is a leading company.
