SK Hynix shares surge after chairman Chey Tae‑won's personal purchase

Chey Tae-won SK Hynix personal share purchase stock rally responsible management

SK Group chairman Chey Tae‑won bought 3,620 ordinary shares of SK Hynix on the open market, valued at about 4.79 billion won (≈ $921 per share). The purchase, disclosed through a filing with the Financial Supervisory Service on July 31, is his first personal holding of SK Hynix stock, having previously exercised control only through SK Square. By keeping the transaction just under the 5 billion‑won threshold, Chey avoided the 30‑day advance filing requirement.

The news spurred a sharp rally in SK Hynix shares, which jumped roughly 25 % intraday to 1.66 million won, and helped lift the broader semiconductor sector, with the Philadelphia Semiconductor Index up 8.19 %. The price rise was reinforced by a rebound in U.S. semiconductor stocks after the company's ADR launch on the Nasdaq. Analysts view the move as a strong bottom‑signal from an insider who believes the chipmaker is undervalued.
