An analysis from Yahoo Finance suggests that Micron Technology (MU) and Taiwan Semiconductor Manufacturing (TSMC) stocks are poised to rebound to fresh all-time highs before the end of 2026. This optimistic outlook is primarily driven by expectations of increased AI spending in 2027, as indicated by major tech companies like Amazon, Alphabet, and Nvidia. Both Micron and TSMC are critical suppliers for AI chips, with Micron producing memory chips and TSMC manufacturing logic chips. The companies are expanding capacity to meet anticipated demand, including TSMC's $100 billion investment in Arizona facilities and Micron's new production facilities. Wall Street analysts project significant growth for both, with TSMC expected to grow 42% for the remainder of 2026 and 32% in 2027, while Micron is forecast for 349% growth in its fiscal 2026 fourth quarter and 85% in fiscal 2027.
