Noteworthy Friday Option Activity: ASTS, RKLB, CAVA

Rocket Lab (RKLB) saw outsized options activity with 190,483 contracts traded (≈19.0M underlying shares), equal to ~68.6% of its one‑month average daily volume (27.8M), led by 12,286 contracts in the $58 put expiring Jan 30, 2026 (≈1.2M shares). CAVA Group (CAVA) recorded 24,362 contracts (≈2.4M underlying shares), about 65.6% of its one‑month average daily volume (3.7M), concentrated in 4,905 contracts of the $67 call expiring Jan 23, 2026 (≈490.5k shares). These concentrations signal significant speculative positioning—bearish skew in RKLB via puts and bullish interest in CAVA via calls—which may lift near‑term volatility and liquidity in both tickers.

Analysis

Market structure: The concentrated flow (RKLB ~12,286 Jan‑30‑2026 $58 puts ≈1.2M shares; CAVA ~4,905 Jan‑23‑2026 $67 calls ≈490.5k shares) implies dealer delta‑hedging will be a near‑term driver — heavy RKLB put flow likely pressured the share price as dealers sell stock, while CAVA call flow likely bids stock via hedging. Direct winners are liquidity providers and short‑term directional option sellers; long‑only holders of RKLB risk mark‑to‑market losses if flows persist.

Risk assessment: Near‑term (days–weeks) risk is flow/gamma amplification and pinning around strikes; medium term (months) risk is IV re‑pricing if the block was a single trader (unwind risk) or if catalysts (RKLB launch failure, CAVA same‑store sales miss) occur. Tail scenarios: an RKLB launch disaster or a sudden revocation of CAVA growth guidance could move shares 40–60% and flip hedges; hidden dependency is that open interest concentration at $58/$67 can create self‑fulfilling support/resistance.

Trade implications: Tactical plays should exploit hedging flows and elevated IV: target asymmetric risk with defined loss. For RKLB, prefer directional hedges (long puts or short equity) sized to 1–2% portfolio risk rather than naked short; for CAVA, prefer call spreads to capture upside while capping premium paid. Consider a dollar‑neutral pair (long CAVA call spread / short RKLB equity) to isolate idiosyncratic gamma.

Contrarian angles: Consensus assumes puts = bearish conviction, but heavy put open interest can create a “put wall” that dealers defend, producing mean reversion if no fundamental deterioration — that makes outright long volatility on RKLB expensive and potentially crowded. Historically, large isolated option blocks have produced transient volatility spikes lasting 2–6 weeks before mean reversion; unintended consequence is gamma‑crowding that can reverse violently on block unwind.

Key Decisions for Investors

• RKLB: Initiate a tactical 1.5% portfolio short via buying Jan 30 2026 $58 puts (or equivalent synthetic) if RKLB trades < $60; set max loss = 20% of position and target rolling to capture a 30–50% downside to ~$40 over 3–12 months, exit if price moves +20% adverse or if open interest at $58 drops >30% over 14 days.
• CAVA: Establish a 2% portfolio long via Jan 23 2026 $67/$80 call spreads (buy $67, sell $80) to cap premium; size so max loss = 2% portfolio, target >100% return if CAVA > $80, enter within next 2 weeks while elevated call flow persists and exit or roll by 30 days before expiry.
• Pair trade: Construct dollar‑neutral exposure by going long $1.0M notional in CAVA call spreads (as above) and short $1.0M notional RKLB equity (or equivalent delta‑neutral short via November/Jan spreads); rebalance monthly and cut the pair if relative return diverges >20% in 30 days.
