Options Indicators

MRVL’s implied volatility stands at 102.97%, and with an IV percentile of 93.63%, current option volatility is firmly in the elevated range, indicating that options are priced expensively relative to their own recent history. The IV/HV ratio of 1.20 further suggests implied volatility is running above realized volatility, meaning the market is embedding a meaningful premium for expected future movement. In this setup, long-option buyers are paying up for volatility, while premium-selling structures or defined-risk spreads may offer a more efficient way to express a view. The Call/Put volume ratio is 2.31.

Large Trades

A $10.25 million two-leg short strangle stood out as one of the day’s biggest option structures, with traders selling 2,500 September 18, 2026 $200 puts and simultaneously selling 2,500 September 18, 2026 $280 calls. This was a net credit position, bringing in premium from both sides, and it appears designed primarily for premium collection with a view that MRVL will remain within a broad range into expiration. Relative to the $194.94 reference price, the $200 put was in the money while the $280 call was out of the money, so the structure reflects a willingness to take downside assignment risk while capping upside participation only far above the current stock price. Strategically, this is a volatility-selling, range-bound stance rather than an outright directional chase.

A $7.73 million two-leg long strangle was the other highlighted block, with traders buying 2,500 August 21, 2026 $200 puts and buying 2,500 August 21, 2026 $250 calls. This was a net debit trade, paying premium for convex exposure on both sides, and it signals a directional volatility bet that MRVL could make a substantial move before expiration. With the stock at $194.94, the $200 put was in the money and the $250 call was out of the money, giving the buyer immediate downside sensitivity while also retaining upside participation if the stock rallies sharply. In strategic terms, this is a move-seeking structure that benefits from a large price swing and can also serve as a hedge against uncertainty while keeping upside optionality alive.

Overall sentiment across all large trades leaned bearish, with $8.28 million in bullish flow versus $12.82 million in bearish flow, leaving a net bearish difference of $4.54 million. The directional judgment is therefore moderately bearish. That conclusion is supported by the heavier concentration of premium-selling and bearish-positioned flow, including sizable short-volatility and call-selling activity, which outweighed the bullish call buying and the upside leg of the long volatility structures. Taken together, the large-trade tape suggests that while some participants are positioning for a major move, the dominant institutional tone remains more cautious to negative on MRVL.

Strategy Reference

For a premium seller in this high-IV environment, selling an out-of-the-money call at a strike like $300 could offer a low probability of assignment, while traders preferring defined risk might consider vertical spreads, such as a bear put spread, to limit margin requirements.
