Options Indicators

MRVL’s implied volatility stands at 93.68%, and with an IV percentile of 84.86%, current option volatility is clearly in the elevated range, indicating that options are priced expensively relative to their own historical levels. The IV/HV ratio of 1.03 suggests implied volatility is only slightly above realized volatility, so while premiums are rich in percentile terms, they are still broadly in line with the stock’s actual recent movement rather than wildly overstated. Overall, option buyers are paying up for volatility here, while premium-selling structures may offer a more favorable starting point from a pricing perspective.

The Call/Put volume ratio is 1.87.

Large Trades

A put sale worth $6.68 million was the largest featured trade, with 3,000 contracts of the December 18, 2026 $150.00 put sold. With MRVL referenced at $188.30, this strike sits out of the money, making the trade a moderately bullish income-style position. The seller is effectively collecting premium while expressing confidence that the stock can remain above $150.00 into expiration, or at least that downside risk to that level is acceptable. Strategically, this points to premium collection with a bullish bias, since the trader benefits most if the put expires worthless and would only be obligated to buy shares on a substantial decline.

A calendar call combination worth $3.23 million was the other displayed large trade, structured as a four-leg diagonalized call spread: long 2,465 July 24, 2026 $195.00 calls, short 2,465 July 24, 2026 $200.00 calls, short 2,465 July 17, 2026 $207.50 calls, and short 2,465 July 17, 2026 $210.00 calls. All strikes are out of the money versus the $188.30 stock reference, and the package was executed for a net debit of $3.23 million. This setup suggests a bullish but controlled directional bet, using the long $195.00/$200.00 call vertical in the later expiry while financing part of the cost through short higher-strike near-term calls. The strategic intent appears to be upside participation with defined structure and cost efficiency rather than outright aggressive speculation, as the trader is positioning for a measured advance while offsetting premium outlay through the front-week call sales.

Overall sentiment in MRVL large trades was clearly bullish, with total bullish flow of $15.70 million versus bearish flow of $3.11 million, leaving a net bullish difference of $12.59 million. The directional read is decisively positive: the flow was led by a large out-of-the-money put sale and reinforced by multiple upside-oriented call purchases and a net-debit calendar call structure, all of which point to expectations for stability to further upside rather than material downside. Taken together, the large-trade profile suggests institutional positioning remains constructive on MRVL, with traders favoring premium-selling support and targeted upside exposure over protective or outright bearish structures.

Strategy Reference

For premium sellers seeking low assignment probability, selling an out-of-the-money put like the $150.00 strike is an example; for defined-risk directional exposure, a bull call spread (e.g., buying a $195.00 call and selling a $200.00 call) can limit capital outlay.
