If You'd Invested $1,500 in Micron Stock 1 Year Ago, Here's How Much You'd Have Today - The Globe and Mail

Micron Technology has emerged as one of the top performers in the market over the past year, with its stock price surging 820%. This remarkable performance is largely driven by strong demand for memor... Read original →

Micron’s 820% stock surge reflects not just AI-driven HBM demand but a fundamental reshaping of semiconductor value chains. Technically, HBM3E/HBM4 ramp-up is forcing rapid advancement in TSV and advanced packaging, with TSMC’s CoWoS capacity now a critical bottleneck inflating AI chip ecosystem costs. On compliance, U.S. export controls compel Micron to shift some Taiwan, China production stateside, spiking capex and pressuring margins. With Samsung accelerating HBM4 qualification and SK Hynix locking in NVIDIA’s GB200 supply chain, Micron must prove its yield leadership in 2.5D/3D stacking. If AI server deployment slows or CPO (co-packaged optics) bypasses next-gen HBM within 18 months, today’s $1.29T valuation becomes unsustainable—memory stocks are morphing from cyclical plays into high-stakes tech bets.
