SK海力士 closed at USD 174.87, up 0.02%.
The options tape showed a pronounced bullish tilt in long-dated contracts, headlined by a USD 35,200 call purchase at the 190 strike while a USD 6,800 call sale at 225 capped extreme upside. The dominant block was an out-of-the-money long call seeking upside participation, and the overall large-trade flow leaned bullish even as some premium sellers positioned for restrained gains.

Options Indicators
SKHY’s implied volatility is 64.06%, while its IV percentile stands at 13.04%, which places current volatility conditions in the low end of its historical range. In other words, although the headline IV level itself is not low in absolute terms, options appear cheaply priced relative to where they have traded over time, and the IV/HV ratio of 1.03 suggests implied volatility is broadly in line with recent realized movement rather than carrying a significant premium.
The Call/Put volume ratio is 1.70.
Large Trades
A call purchase worth $35,200 was the largest displayed trade, with 1,006 contracts bought at the 190.0 strike expiring on 2026-09-18. With SKHY referenced at 174.87, this call was out of the money, making it a clearly bullish directional position that looks geared toward upside participation over a long-dated horizon. The buyer was paying premium for leverage to a move above 190.0, suggesting expectations for appreciation rather than income generation.
A call sale worth $6,800 was the other notable trade, with 6,844 contracts sold at the 225.0 strike expiring on 2026-09-18. This option was also out of the money versus the 174.87 reference price, so the trade reads as a bearish-to-neutral stance, most likely expressing the view that SKHY is unlikely to rally all the way to 225.0 by expiration. Strategically, this type of short call positioning is typically associated with premium collection or upside capping rather than an outright bullish bet.
Overall, the large-trade flow leans bullish. The dominant trade by premium was the long out-of-the-money 190 call, which points to upside speculation, and it outweighed the smaller out-of-the-money 225 call sale that reflected more restrained or income-oriented positioning. Taken together, the block activity suggests investors see room for gains from current levels, but with some willingness elsewhere in the flow to fade more extreme upside.
Strategy Reference
For sellers seeking a low assignment probability, the 225 call already sold in size offers a template, though its long-dated tenor requires patience; for a defined-risk bullish view without excessive margin, consider a 190/225 call spread to finance the upside while capping extreme gains.
