SK hynix ended the latest session at USD 190.07, up 0.94%.

Despite the modest gain, SKHY’s options flow was dominated by an institutional bearish call spread with a net credit of $4.31 million, signaling expectations for limited upside through December 2026. The session lacked any offsetting bullish large-trade activity, leaving the longer-dated options tape skewed toward cautious-to-negative sentiment.

Options Indicators

SKHY’s implied volatility is 62.42%, while its IV percentile is just 4.65%, which indicates that although the absolute IV level appears high, it sits near the low end of its own historical range. In other words, current option pricing is relatively cheap rather than expensive, and with the IV/HV ratio at 0.95, implied volatility is also running slightly below realized volatility, suggesting options are being priced a bit under recent actual movement.

The Call/Put volume ratio is 1.41.

Large Trades

A bearish call spread with a net credit of $4.31 million was the standout large trade in SKHY. The position sold 2,212 Dec. 18, 2026 $150.00 calls, which were in the money versus the $190.07 reference price, and bought 4,424 Dec. 18, 2026 $225.00 calls, which were out of the money, forming a bear call spread structure. As a spread strategy, its size is measured by the stated net credit of $4.31 million rather than the gross leg turnover. This setup reflects a premium-collection trade with a bearish bias, expressing the view that upside should remain limited through expiration while capping risk through the long higher-strike calls.

Overall, the large-trade flow in SKHY was clearly bearish. The session’s only displayed institutional-scale order was a bear call spread established for net premium intake, which typically signals expectations for muted upside or price weakness rather than a push to new highs. With no offsetting bullish large-trade activity in the bulk-order flow, the options positioning points to cautious-to-negative sentiment and suggests traders are leaning toward constrained upside over the longer-dated horizon.

Strategy Reference

For a low assignment probability on the short side, a seller could consider the Dec. 18, 2026 $225.00 calls, which are already the long strike of the institutional spread but would still carry elevated premium relative to the low IV percentile environment; alternatively, a bear call spread of selling the $150.00 calls and buying the $225.00 calls requires a defined margin of $75.00 per share before the net credit, making it a capital-efficient way to express the same capped-upside thesis.
