Micron Technology (MU) shares have fallen approximately 23% from their June 25th all-time high of $1,213, as investors grow concerned about competition and the sustainability of its high margins. Despite a 346% year-over-year revenue increase to $41.5 billion in the third quarter and an 85% gross margin, the stock trades at a forward price-to-earnings multiple of just 6. Analysts believe this discount reflects investor skepticism that the current boom, driven by generative AI demand, will last due to the commoditized nature of memory chips and increasing production capacity, including China's YMTC aiming to be the top NAND producer by 2027.
