Morningstar analyst Jing Jie Yu said market uncertainty about potential capital
spending by Samsung Electronics and SK Hynix may be pressuring their share
prices. He estimates combined capex could reach about 2,000 trillion won over
the next decade—roughly double Morningstar's current forecast—including SK
Hynix’s planned AI data‑center investment, with pledged spending on the Yongin
wafer‑fab cluster around 600 trillion won. Yu warned that if SK Hynix’s AI
data‑center commitments are separate from its broader capex plans, the
memory‑chip sector could face a material supply‑overhang risk because demand
typically slows as a capex cycle matures.
