Bullish Thesis Analysis on Merck & Co., Inc.
- Institutional Trading Signal: On December 8, 2025, Merck & Co., Inc. (MRK) saw an unusually large institutional options trade, purchasing 30,000 April 2026 $110 call contracts, representing approximately $300 million in notional exposure, executed as MRK retraced to its 21-day exponential moving average, indicating confidence in medium-term repricing.
- Catalyst Expectations: The choice of April 2026 expiration aligns with multiple anticipated catalysts, including FY2025 earnings, early 2026 pipeline updates, and increasing visibility into Merck's post-Keytruda growth trajectory, collectively enhancing investor confidence.
- Capital Efficiency Optimization: The bullish thesis proposes a split-strike risk reversal strategy, selling April $85 puts to finance the $110 calls, anchoring downside risk to the 200-day simple moving average, a level widely viewed as a structural accumulation zone for a high-quality defensive stock.
- Fundamental Support: The accelerating launch of Winrevair is tracking toward blockbuster status, while the durability and lifecycle extension of Keytruda, along with a deepening pipeline in cardiology, vaccines, and respiratory diseases, further solidify investor confidence, as the structure offers limited downside with uncapped upside potential.
