SK hynix finished the session at USD 162.09, down 1.58%.
The options market showed a notable bullish undercurrent despite the decline. The most significant print was a $948,000 sale of out-of-the-money puts, indicating a premium-collecting stance. Overall flow leaned positive, with call volume outpacing puts and no large defensive blocks appearing. Traders appeared to use the dip as an opportunity to sell downside protection rather than chase downside momentum.

Options Indicators
SK hynix currently has an implied volatility (IV) of 64.95%, while its IV percentile stands at 38.96%, which places current volatility expectations in a neutral historical range rather than an elevated one. With the IV/HV ratio at 0.83, implied volatility is running below realized volatility, suggesting options are not carrying an aggressive premium at the moment and appear relatively fairly to modestly priced rather than expensive.
The Call/Put volume ratio is 1.18.
Large Trades
A PUT sale worth $948,000 was the standout large trade, with 1,200 contracts sold on the January 15, 2027 $140.00 put. With SKHY referenced at $162.09, this strike sits out of the money, so the seller is expressing a moderately bullish stance by betting the shares remain above $140.00 through expiration. Strategically, this type of trade is typically used for premium collection or for positioning to potentially acquire stock at a lower effective entry level, reflecting confidence that downside risk will stay contained over the life of the option.
Overall, the large-trade flow points to a bullish bias in SKHY. The key signal is that the only notable block in the session was an out-of-the-money put sale, which generally aligns with investors willing to monetize time decay while leaning on support below the current share price. That pattern suggests market participants are not aggressively positioning for a sharp decline and instead appear comfortable with a stable-to-higher outlook.
Strategy Reference
For a similar low-assignment-probability setup, a seller could consider the $130.00 or $125.00 strike in the same January 2027 expiration for a wider downside cushion; alternatively, a bull put spread such as selling the $140.00 put and buying the $120.00 put can reduce margin requirements while still capturing net premium.
