Options Indicators

SKHY’s implied volatility is 146.19%, and with an IV percentile of 100.00%, current option volatility sits at the extreme high end of its historical range. That means options are priced expensively, with the market embedding very elevated volatility expectations. At the same time, the IV/HV ratio of 0.59 indicates implied volatility is below realized volatility, suggesting that despite the very high absolute IV level, the market’s forward volatility pricing is still running under recently observed actual movement.

The Call/Put volume ratio is 1.19.

Large Trades

A CALL buy worth $42.18 million was the standout large trade, with 10,000 contracts of the August 21, 2026 $125.0 call purchased. With SKHY referenced at $154.03, this strike was in the money at execution, which makes the trade especially notable as a high-conviction bullish position rather than a low-cost lottery-style upside bet. The buyer was paying for substantial intrinsic value and long-dated upside exposure, signaling a directional view that the stock can remain elevated or extend higher over time. Strategically, this is a straightforward bullish bet that expresses confidence in sustained strength while locking in upside participation through 2026.

A same-direction double-buy put combination worth $3.32 million was the second key large trade, consisting of purchases of August 21, 2026 $105.0 puts across two blocks totaling 5,850 contracts. This was a net debit structure, as both legs were bought, and with the $105.0 strike below the $154.03 reference price, the puts were out of the money at execution. The setup points to a directional volatility-oriented downside expression rather than premium collection, as the trader paid premium to gain convex exposure to a potentially sharp decline. In practical terms, this combination suggests a bearish hedge or speculative protection against a large downside move, with value rising if SKHY were to weaken materially before expiration.

Overall sentiment was clearly bullish. Total bullish large-trade flow reached $42.66 million, while total bearish flow was $4.09 million, leaving a net difference of $38.57 million to the bullish side. The directional judgment is therefore decisively positive, driven overwhelmingly by the massive in-the-money long call purchase that dominated all other activity. Although there was meaningful downside interest through long puts, that bearish positioning was comparatively small and looks more like protection or a tactical volatility play than a dominant market view. Taken together, the large-trade profile reflects strong institutional confidence in upside potential, with limited but visible hedging against a sharp reversal.

Strategy Reference

For traders seeking income with a neutral to bullish outlook and low assignment risk, selling out-of-the-money cash-secured puts, such as at the $105.00 strike, could be considered; for those bullish but wanting to reduce capital outlay, a bull call spread using the $125.00 and $175.00 strikes is a defined-risk alternative.
