Notable Wednesday Option Activity: MDB, SNOW, CORZ

Snowflake (SNOW) saw 41,425 options contracts trade today, equivalent to roughly 4.1 million underlying shares — about 107.3% of its one‑month average daily volume — led by 5,406 contracts in the $240 Jan 16, 2026 put (~540,600 shares). Core Scientific (CORZ) had 113,971 option contracts trade, ~11.4 million underlying shares or ~106.5% of its one‑month ADV, led by 15,500 contracts in the $27 Mar 20, 2026 call (~1.6 million shares). These outsized flows suggest concentrated directional or hedging activity and imply elevated short‑term volatility and positioning interest in both names.

Analysis

Market structure: Large option trades in SNOW ($240 Jan 16 2026 puts, ~540.6k shares) and CORZ ($27 Mar 20 2026 calls, ~1.55M shares) represent ~14% of each name’s ADV per strike and can force meaningful short-term delta-hedge flows; market makers selling those options will likely sell SNOW stock and buy CORZ stock into the next 1–10 trading days, amplifying intraday/weekly moves. Winners are liquidity providers and directional option buyers if hedging is aligned with the trade; losers are passive long-only holders who face transient volatility and potential forced selling during gamma ramp. Cross-asset: CORZ flow increases tail correlation with BTC and energy costs (miner economics), while SNOW flow feeds tech-sector volatility and could push implied vol indices higher, modestly affecting IG credit spreads on tech names via risk‑off repricing.

Risk assessment: Tail risks include CORZ operational/regulatory shocks (energy contract loss or miner seizure) and SNOW enterprise revenue deceleration or large customer churn; both are low-probability/high-impact through 2026 expiries. Immediate (days) risk is gamma-driven price moves; short-term (weeks–months) risk is elevated IV and repricing into earnings; long-term (quarters–years) risk is fundamental (ARR growth for SNOW, BTC price/hashrate for CORZ). Hidden dependencies: these block-sized option prints may be part of multi-legged institutional hedges, convertible/loan hedging, or index reweights — not pure directional bets. Key catalysts: SNOW quarterly results/guide (next two quarters), CORZ cashflows/energy contracts and BTC price moves within 3–6 months.

Trade implications: For SNOW, prefer defined-risk bearish hedges: buy Jan‑16‑2026 $240/$180 put spread sized 1–2% NAV to cap cost while preserving downside insurance; consider writing 30–60 day 2–5% OTM calls against existing long positions to harvest IV if you expect mean reversion. For CORZ, pursue asymmetric long exposure: buy Mar‑20‑2026 $27/$45 call spreads at 0.5–1% NAV (max loss limited, target 2–3x if BTC > $40–50k or miner fundamentals improve); scale into position over 3 trading days to avoid front-running gamma. Reduce outright long-duration passive exposure to either name by 25–50% if not hedged before earnings/catalyst windows.

Contrarian angles: Consensus that large put prints equal pure bearishness may be wrong — many prints are protection for long-held positions, so IV spikes can be overstated and mean-revert after magnet dates; selling premium after IV pops (e.g., 20–35% increase) can be profitable but requires strict risk limits. Historical parallels: 2018–2021 big-option-driven squeezes produced short-term dislocations that reversed post-catalyst; don’t confuse gamma-driven moves with fundamental regime shifts. Unintended consequence: aggressive delta-hedging by market makers can create feedback loops that force temporary liquidity gaps — use spreads not naked positions to avoid being on the wrong side of a squeeze.

Key Decisions for Investors

• Establish a 1–2% NAV protective position in SNOW via a Jan‑16‑2026 $240/$180 put spread (buy) within 5 trading days to cap downside exposure; close or reassess after SNOW’s next two earnings releases or if IV drops >30% from present levels.
• Allocate 0.5–1% NAV to CORZ Mar‑20‑2026 $27/$45 call spreads (buy) over 3 days, with profit-taking: sell half at +50% and the remainder at +100%; hard stop at -30% loss on cost, reassess if BTC price moves >±20% in 30 days.
• If long either equity without hedges, sell 30–60 day 2–5% OTM calls for 2–4% of notional to harvest near-term IV (roll monthly) but cap exposure by sizing to <=50% of the underlying position to avoid large assignment risk.
• If IV spikes >25% for SNOW or CORZ after these prints, opportunistically sell long-dated (9–12 month) 10–15% OTM puts (size <=0.5% NAV) to capture premium, but require cash-covered reserve and close if price breaches strike by >10%.
