Notable Thursday Option Activity: GS, CRWD, BKNG

CrowdStrike saw an unusually large options flow today with 29,782 contracts traded (roughly 3.0 million underlying shares), equal to about 136.8% of its one‑month average daily volume; activity was concentrated in the $380 put expiring Jan. 16, 2026 (1,369 contracts, ~136,900 shares). Booking Holdings recorded 2,216 contracts (~221,600 shares), or about 77.8% of its one‑month ADTV, highlighted by 110 contracts in the $4,700 put expiring Sept. 17, 2027 (~11,000 shares). The size and put‑skew of these trades represent outsized hedging or directional downside interest versus typical liquidity in both names and may be relevant for short‑term price and volatility expectations.

Analysis

CrowdStrike exhibited unusually large options flow today with 29,782 contracts traded, representing roughly 3.0 million underlying shares and about 136.8% of CRWD's one‑month average daily volume of 2.2 million shares. Activity was concentrated in the $380 strike put expiring January 16, 2026, where 1,369 contracts (≈136,900 shares) traded, indicating meaningful downside or hedging interest concentrated in a single out‑of‑the‑money put series.

Booking Holdings showed elevated but smaller relative activity with 2,216 contracts (≈221,600 shares), equivalent to 77.8% of its one‑month ADTV of 284,665 shares; the $4,700 put expiring September 17, 2027 saw 110 contracts (≈11,000 shares). The flows in both names are put‑skewed and large relative to typical liquidity, which can raise near‑term implied volatility and create dealer hedging flows that amplify equity moves.

Data signals classify sentiment as mildly negative and market impact as moderate (0.3), supporting the interpretation that trades reflect either institutional downside positioning or sizeable hedging rather than routine retail activity. The article provides no open‑interest or buyer/seller aggressor detail, so the directional intent (protective hedge versus bearish purchase) remains inconclusive and should be confirmed with subsequent price, IV, and order‑flow data.

Key Decisions for Investors

• Monitor CRWD implied volatility and option skew closely and consider hedging or reducing directional long exposure given a put flow equal to 136.8% of ADTV in a single day
• For BKNG, refrain from adding material long positions until follow‑through in price or open interest confirms whether the 77.8% ADTV put activity reflects hedging or fresh bearish bets
• Use execution caution and scale entries/exits because these option trades are large relative to liquidity and may induce temporary price moves from dealer hedging
• Seek confirming signals (changes in open interest, buyer/seller trade prints, near‑term IV term structure and underlying price action) before changing conviction
