The memory chip sector is trading higher, driven by a persistent and structural demand surge from the artificial intelligence industry. News reports on October 19th highlight this trend, with Samsung reportedly tapping TSMC for next-generation High Bandwidth Memory (HBM) for Nvidia, and Chinese competitor CXMT forecasting a more than eightfold revenue increase due to AI demand. This comes amid an ongoing supply shortage across DRAM and NAND, with analysts noting that HBM capacity is sold out through 2027, giving manufacturers significant pricing power.
