SNDK closed at USD 1,015.89, a decline of 7.32 percent from the prior session.
A massive $137.84 million long straddle dominated the options tape, signaling bets on a significant future price swing, while a smaller $2.04 million bear put spread introduced a cautious hedge. The session reflected a split personality, with heavy demand for explosive movement in either direction tempered by a distinct layer of downside protection.

Options Indicators
SNDK’s implied volatility is 142.22%, and with an IV percentile of 95.22%, current option pricing sits in a clearly elevated regime. That means implied volatility is not only extremely high in absolute terms, but also rich versus its own recent history, so options are priced expensively. The IV/HV ratio of 1.04 further suggests implied volatility is only modestly above realized volatility, indicating the market is still assigning a premium to forward uncertainty, but not at an unusually stretched level relative to actual movement. The Call/Put volume ratio is 1.07.
Large Trades
A paired long call and long put position worth $137.84 million was the dominant large trade of the day, consisting of 1,700 June 17, 2027 $1,000 calls bought for $72.49 million and 1,700 June 17, 2027 $1,000 puts bought for $65.35 million. This is a long CALL+PUT combination, effectively a long straddle around the $1,000 strike, established for a net debit. With the stock reference price at $1,015.89, the call was in the money while the put was out of the money at execution. Strategically, this reflects a volatility-focused directional setup rather than premium collection, as the buyer is paying substantial premium to gain exposure to a large move in either direction over a long-dated horizon.
A bear put spread worth $2.04 million added a smaller but clearly bearish layer to the tape, built by buying 2,950 December 18, 2026 $210 puts for $1.10 million and selling 2,950 December 18, 2026 $200 puts for $0.94 million. This is a classic bearish vertical put spread entered for a net debit, expressing a downside view while capping both maximum profit and upfront cost. Both strikes were out of the money versus the $1,015.89 reference stock price, which makes the structure a lower-cost tail-risk or downside-conviction trade rather than an immediate in-the-money hedge.
The directional judgment is modestly positive, but the tone is far from one-sided. That is because the overwhelming flow was concentrated in a massive long straddle-like CALL+PUT purchase, signaling demand for major future price movement rather than a pure upside chase, while the smaller bear put spread shows some explicit downside positioning remained present. Taken together, the large-trade picture suggests cautious bullishness embedded within a broader expectation of elevated volatility.
Strategy Reference
With IV in the 95th percentile, premium sellers might consider deep out-of-the-money puts, such as the June 2027 $600 strike, to capture elevated volatility while maintaining a low probability of assignment, though margin requirements remain substantial.
