The semiconductor materials market may encounter a significant supply bottleneck akin to the "Strait of Hormuz," according to Serenity, a noted stock analyst. The disruption in Japan's supply chain of tungsten hexafluoride (WF₆), a critical component in semiconductor manufacturing, could impact major players like SK Hynix, Samsung Electronics, and TSMC. This disruption stems from external trade and export controls, potentially affecting a quarter of the global wafer manufacturing capacity. South Korean company Foosung Co., Ltd., with a market cap of approximately $1.2 billion, is poised for a critical revaluation. Currently accounting for about 10% of the global WF₆ supply, Foosung's strategic importance may rise amid supply chain contractions. Serenity highlights that while these insights are based on market observations, they do not hold any positions related to this scenario.
