Context

Context

SK Hynix has repurchased ₩25.5 trillion of shares, covering 61% of its program and is on track to finish by mid‑October, earlier than planned.

Expected impact

Likely modest price support; may benefit from correlated foreign inflows into Korean memory stocks.

Evidence & confidence

The scale of the buyback and its timing create a short‑term demand boost.

Market effects

Reduced supply pressure on the KOSPI may aid other large‑cap Korean equities and memory‑chip sector sentiment.

Potentially steadier Korean market ahead of foreign inflows; may influence regional ETFs tracking Korea.

Limited to investors with exposure to Korean equities; no direct global impact.

Counterpoint

If foreign investors remain net sellers, the early buyback completion could expose a supply gap, leading to price weakness.
