Marvell ended the session at $133.55, sliding 16.43% from the prior close.
Large options trades in Marvell leaned decisively bearish after the sharp sell-off. A $52.00 million double-put purchase and a $10.50 million bear put spread stood out, reflecting aggressive institutional positioning for further downside rather than a rebound. The concentration of put-heavy flow suggests big-money traders are treating the 16.43% slide as the start of a longer period of weakness, not a one-day dip, with major blocks concentrated in longer-dated downside structures.

Options Indicators
Marvell’s implied volatility is 98.28%, and with an IV percentile of 83.27%, current option volatility sits in an elevated range, indicating that options are priced expensively relative to their own recent history. The IV/HV ratio of 1.04 also suggests implied volatility is only modestly above realized volatility, so the market’s premium is rich, but not dramatically disconnected from actual movement. In this setup, option buyers are paying up for volatility exposure, while premium-selling or defined-risk spread structures may offer a more efficient way to approach the name.
The Call/Put volume ratio is 0.73.
Large Trades
A directional double-put purchase worth $52.00 million was the standout large trade, consisting of long 270.0 puts and long 260.0 puts expiring on 2026-12-18. Both legs were in the money versus the reference stock price of 133.55, with transaction amounts of $27.02 million and $24.99 million, respectively. Because this is a same-direction double-buy put combination, it reflects an aggressive bearish volatility bet rather than a defined-risk spread, indicating the trader is positioning for substantial downside and potentially a sharp move lower over a longer-dated horizon.
A bear put spread with a net debit of $10.50 million was the other highlighted block, pairing a purchase of 135.0 puts expiring on 2027-01-15 with a sale of 85.0 puts expiring on 2027-03-19. The long 135.0 put was in the money, while the short 85.0 put was out of the money, and the structure expresses a moderately bearish view with defined financing from the short lower-strike leg. As a spread strategy, this net-debit position points to a downside directional bet with some cost reduction, suggesting the trader expects weakness in MRVL but within a more measured payoff framework than the outright double-put purchase.
Overall, the large-trade flow in MRVL leans clearly bearish. The most meaningful orders were dominated by put-heavy downside structures, including aggressive long-put combinations and bear put spreads, showing that institutional activity was concentrated on protecting against or speculating on further weakness rather than chasing upside. Even though there were some premium-selling and selectively bullish trades elsewhere in the tape, the character and scale of the major block activity indicate cautious-to-negative market sentiment with expectations tilted toward continued downside pressure.
Strategy Reference
For a low assignment probability sell-side approach given elevated IV, an out-of-the-money put seller could consider the 85.0 strike in a nearer-dated expiration, or use a defined-risk bear put spread like long 135.0/ short 85.0 if margin efficiency is a priority.
