On September 28, SK hynix fell 3.11% overnight, trading at $185.33/share, with turnover of $27.21 million.

On the news front, a prominent bearish signal emerged from the options market: a synthetic put structure worth approximately $6.895 million appeared at the 190.0 strike price expiring October 16, constructed via selling calls and buying puts, generating a net credit of $70,000 — a clear directional bearish bet. Additionally, a separate batch of deep-in-the-money covered call positions totaling $1.5185 million further reinforced the dominance of short-side positioning near at-the-money levels.

Meanwhile, the broader semiconductor sector came under pressure. Micron Technology fell 0.9%, Intel dropped 1.26%, Advanced Micro Devices lost 0.62%, Broadcom declined 0.37%, and NVIDIA slipped 0.24%, creating an unfavorable sector backdrop that compounded selling pressure on SK hynix. Elevated U.S. Treasury yields, with the 10-year recently breaching the 5% threshold, have continued to weigh on high-multiple growth names across the chip space.
