Why is Seagate Technology stock sliding today?

Seagate Technology's stock fell 5.2% to $713.88 in pre-market trading, driven by a global chip selloff and competition fears from Chinese and Japanese firms. The selloff was triggered by ChangXin Memory's announcement of new DRAM designs and AI data center products, alongside Toshiba's plans to expand HDD production. Seagate reported strong Q4 revenue of $3.63B, up 48% YoY, but market concerns focus on potential supply-side risks.
