SK hynix closed at USD 142.72, down 0.70%.

A massive $46.25 million bullish call spread dominated the options tape in SK hynix, signaling a strong institutional bet on a long-term rally through 2026. The bullish structure was partially offset by a smaller $3.45 million short call, suggesting a measured view where upside is capped at higher levels, resulting in an overall bullish but controlled flow picture.

Options Indicators

SKHY’s implied volatility is 118.77%, but its IV percentile is only 6.67%, which indicates that despite the high absolute IV level, current option pricing sits near the low end of its own historical range. Combined with the IV/HV ratio of 0.71, this suggests implied volatility is running below realized volatility and that options appear relatively cheap rather than richly priced, with volatility conditions on the low side versus the stock’s recent history.

The Call/Put volume ratio is 1.40.

Large Trades

A bullish call spread with a displayed trade amount of $46.25 million was the standout large transaction, built by buying 6,761 Dec. 18, 2026 $150 calls and selling 13,522 Dec. 18, 2026 $210 calls. Both legs were out of the money versus the $142.72 reference stock price, and the structure clearly targets upside participation while capping gains above the short-call strike. Based on the leg premiums shown, this spread carried a net premium paid of $0.68 million, making it a net-debit bullish position that seeks directional upside exposure with defined cost and limited reward beyond $210. The trader appears to be positioning for a longer-dated advance in SKHY, but in a risk-controlled way rather than through outright call buying.

A call sale worth $3.45 million involved selling 2,500 Jan. 15, 2027 $250 calls, a strike that is also out of the money relative to the current stock reference. As a single-leg short call, this is a bearish to neutral expression, collecting premium while betting that SKHY is unlikely to rally to that level by expiration. Strategically, it suggests income generation or a view that upside is limited over the long horizon, though the uncovered nature of a standalone short call would also imply meaningful risk if the stock were to make an unexpectedly strong move higher. Overall, the sentiment from all large trades is clearly bullish. The flow is dominated by the much larger upside-positioning call spread, and although there are some bearish premium-selling trades in out-of-the-money calls, they are modest in size compared with the bullish activity. Taken together, the large-trade tape points to institutional confidence in further upside for SKHY, with participants favoring structured bullish exposure rather than aggressive outright speculation.

Strategy Reference

For traders seeking a neutral-to-bullish premium selling strategy with a low assignment probability, the Jan. 15, 2027 $250 call strike, which has already attracted institutional selling, offers a reference point for generating income well above the current price and the large spread’s capped ceiling.
