Noteworthy Friday Option Activity: TDOC, CAH, STNG

Significant options activity was reported in Cardinal Health (CAH) and Scorpio Tankers (STNG): CAH saw 8,388 contracts traded today (≈838,800 underlying shares), about 45.5% of its one‑month ADTV (1.8M shares), led by 6,804 contracts in the $250 call expiring March 20, 2026 (≈680,400 shares). STNG recorded 4,879 contracts (≈487,900 shares), roughly 45.4% of its one‑month ADTV (1.1M shares), led by 2,282 contracts in the $67.50 call expiring February 20, 2026 (≈228,200 shares). The flows indicate concentrated call buying/positioning in both names but the piece is descriptive and does not provide fundamental drivers or guidance.

Analysis

Market structure: concentrated buying of long-dated CAH Mar-20-2026 $250 calls (6,804 contracts ≈680k shares) and STNG Feb-20-2026 $67.50 calls (2,282 contracts ≈228k shares) creates dealer delta-hedging demand that can transiently bid the underlyings; expect 1–6 week upward price pressure if dealers buy stock to hedge. Winners in the near term are liquidity providers, call buyers and existing shareholders; losers are short-dated volatility sellers and any cash-flow-dependent shorts that face forced covering.

Risk assessment: tail risks include regulatory action or margin stress for CAH (healthcare reimbursement shock) and a sudden collapse in tanker rates or oil demand for STNG; treat these as low-probability/high-impact over 3–12 months. Hidden dependency: large blocks may be part of structured spreads or institutional collars, not pure directional bets — implied volatility (IV) and skew are the best single indicators to distinguish speculation from hedging.

Trade implications: prefer defined-risk option structures and small equity exposures while IV is elevated. For CAH, lean into short-term long exposure funded by selling elevated OTM near-term calls or using debit spreads to cap max loss; for STNG, use calendar or vertical call spreads to play freight-cycle upside while limiting theta bleed. Rebalance sector allocation away from rate-sensitive equities if IV-driven flows push correlation higher across healthcare/shipping with bond yields.

Contrarian angles: consensus that heavy call volume = bullish may be wrong — dealers could be net sellers creating temporary pop then mean reversion once hedges roll off. If IV rises >30% relative to 90-day average, favor selling premium via spreads; if open interest concentrates further (>50% of OI in a single strike), treat as crowded and scale positions to 0.5–2% notional each.

Key Decisions for Investors

• Cardinal Health (CAH): Do NOT chase the Mar-20-2026 $250 single-leg calls. Instead, establish a 1.5% portfolio position via a 9–12 month call debit spread sized to limit downside (example: buy Mar-2026 call / sell a higher strike call) within two weeks if CAH price confirms a 3%+ move on >2x average volume; set a hard stop at -40% of premium and a 12–18 month target of +80–150% if realized.
• Scorpio Tankers (STNG): Allocate 1% notional to a Feb-20-2026 $67.50 call vertical (buy lower strike, sell $67.50 or higher) to capture freight rebound while capping theta; increase to 2% only if Baltic Dirty Tanker Index (BDTI) rises >15% over 30 days or Brent holds above $80/bbl for 60 days.
• Volatility play / income: If implied vol for CAH or STNG spikes >30% vs 90-day average and open interest concentrates (>40% of OI in single strike), sell limited-risk call credit spreads (size 0.5–1% each) against those strikes to harvest premium, hedging with correlated equities or delta-hedges intraday.
• Risk management & monitoring: Before adding to either position, require (a) public options tape confirming multiple-buy prints (not single block), (b) IV term structure check (front vs back month), and (c) confirm no earnings/M&A events within 14 days; reduce total combined exposure to these trades to ≤5% portfolio.
