Notable Monday Option Activity: KD, UAL, MRVL

Options on United Airlines and Marvell saw unusually heavy activity today: UAL totaled 26,699 contracts (~2.7M underlying shares), about 46.2% of its one‑month average daily volume, highlighted by 4,112 contracts in the $105 call expiring Nov. 21, 2025 (~411,200 shares); MRVL printed 69,835 contracts (~7.0M underlying shares), ~43.9% of its one‑month average, led by 12,738 contracts in the $83 put expiring Nov. 28, 2025 (~1.3M shares). These concentrated strike-and-expiration flows point to sizable directional bets or hedges that could signal heightened stock-specific positioning and potentially greater near- to medium-term volatility for both names.

Analysis

Options activity in United Airlines (UAL) and Marvell Technology (MRVL) was unusually heavy today: UAL printed 26,699 contracts (~2.7 million underlying shares), about 46.2% of its one‑month average daily trading volume, led by 4,112 contracts in the $105 call expiring Nov. 21, 2025 (~411,200 shares). MRVL saw 69,835 contracts (~7.0 million underlying shares), roughly 43.9% of its one‑month average, dominated by 12,738 contracts in the $83 put expiring Nov. 28, 2025 (~1.3 million shares).

The concentration at specific strikes and multi‑month expirations signals sizeable directional bets or hedges rather than dispersed volatility trades; UAL’s flow was call‑heavy (ticker sentiment modestly positive), while MRVL showed large put demand (ticker sentiment negative). The article’s market impact score (0.28) and theme classification around derivatives and flows point to meaningful positioning that could presage elevated name‑specific volatility if flows persist.

These option volumes represent material fractions of daily share volume and can influence implied volatility, skew, and short‑term liquidity at highlighted strikes, particularly into the noted expirations. Investors should view the prints as a signal to monitor follow‑through in underlying price action and option‑implied metrics rather than as definitive directional proof from a single session.

Key Decisions for Investors

• Monitor UAL and MRVL option‑implied volatility, open interest and underlying price action over the coming days to confirm whether these are persistent flows or a one‑day spike
• Given the concentrated $105 UAL call activity, consider modest, tactical bullish exposure only after confirming follow‑through and manage position size due to potential IV expansion
• For MRVL, treat the large $83 put flow as a warning signal: cover or hedge downside exposure if you are long, or use put buying/put spreads to hedge selectively
