Notable Tuesday Option Activity: AI, UAL, OKLO

United Airlines options traded 25,117 contracts today (≈2.5M underlying shares), equal to roughly 42% of UAL's one‑month average daily volume of 6.0M shares, with particularly heavy activity in the $102 call expiring Dec 19, 2025 (2,082 contracts, ≈208,200 shares). Oklo saw 62,882 option contracts trade (≈6.3M underlying shares), about 41.8% of its one‑month ADV of 15.0M shares, led by the $100 put expiring Dec 19, 2025 (3,843 contracts, ≈384,300 shares); such concentrated option flows could reflect sizable directional bets or hedges that may influence intraday positioning in each equity.

Analysis

Market structure: The unusually large long-dated flow in UAL (25,117 contracts ≈2.5M shares, ~42% of ADV) and heavy puts in OKLO (62,882 contracts ≈6.3M shares, ~42% of ADV) is a high-prop/hedge-block signal rather than broad retail noise given size versus ADV. For UAL that flow mechanically forces dealer delta-buying into the equity (upward pressure in days–weeks) while OKLO put pressure will create delta-selling into the market; expect 1–7 day directional amplification of 3–8% if positions are large enough to move liquidity pockets. Cross-asset: short-term tightening in credit spreads for UAL’s bonds is possible if equity appreciation reduces perceived default risk, while jet-fuel sensitivity remains the dominant commodity tail (Brent move >$5/bbl shifts airline margins materially).

Key Decisions for Investors

• Establish a tactical 1.5–2.5% long equity position in UAL within 3 trading days to capture dealer-driven momentum; hedge with a 1% notional Dec 19, 2025 protective put (choose ~10–15% OTM) to cap downside to ~-15% if broad selling occurs.
• Implement a long-dated bullish call spread instead of outright calls on UAL: buy Dec 19, 2025 90/120 call spread sized to 1.5% of portfolio to limit premium outlay and target 40–60% gross return if UAL >102 by expiry; trim half if position gains >25% in 30 days due to IV compression.
• Take a small 0.5–1.0% directional short or long-put-spread in OKLO (buy Dec 19, 2025 100/70 bear put spread) given concentrated put flow; size small due to liquidity/vol risk and exit if price moves >25% against you or if open interest concentration drops by >50% in 2 weeks.
• Relative-value pair: long UAL (1.5%) and short Delta (DAL) or Southwest (LUV) (combined 1.0–1.5% short) over 1–3 months to capture idiosyncratic flow in UAL; unwind if UAL/DAL spread narrows by >150 bps or UAL gap >8% intraday.
