Merck’s sharp intraday rally reflects a confluence of regulatory wins, analyst upgrades, and robust technical momentum. The stock’s 3.76% surge has pushed it closer to its 52-week high of $105.068, fueled by FDA approvals for Keytruda and a Wells Fargo upgrade. With options activity intensifying and technical indicators flashing bullish signals, investors are recalibrating their strategies to capitalize on the momentum.

FDA Approvals and Wells Fargo Upgrade Fuel Merck’s Rally
Merck’s intraday surge is directly tied to two catalysts: the FDA’s approval of Keytruda in combination with Padcev for bladder cancer and a Wells Fargo upgrade to 'Overweight'. The regulatory nod expands Keytruda’s therapeutic applications, reinforcing its role in Merck’s oncology portfolio. Simultaneously, Wells Fargo’s upgrade cited 'a future beyond Keytruda', highlighting confidence in Merck’s pipeline and dividend sustainability. These developments, coupled with Q3 earnings outperformance and a 4.9% dividend hike, have ignited investor optimism, driving the stock to its highest level since late 2024.

Pharma Sector Gains Momentum as Merck Outperforms Peer Johnson & Johnson
The pharmaceutical sector has seen mixed performance, with Merck outpacing Johnson & Johnson (JNJ), which rose 0.45% intraday. While JNJ’s modest gain reflects broader sector stability, Merck’s 3.61% rally underscores its leadership in oncology innovation. The FDA’s recent approvals for Keytruda and the Wells Fargo upgrade position Merck as a sector bellwether, contrasting with peers facing patent expirations or regulatory delays. This divergence highlights Merck’s ability to monetize its blockbuster drug portfolio and pipeline advancements.

Backtest Merck Stock Performance
The event-study backtest is complete. Key observations:• From 2022-01-01 to 2025-11-24 we detected 7 trading days in which Merck (MRK.N) closed at least 4 % higher than the previous session. • Over the subsequent 30-day windows, the strategy did not show statistically significant excess return versus holding the stock continuously: cumulative median return after 30 days was -1.86 %, while the benchmark (buy-and-hold) gained 0.53 %. • Win-rates never exceeded 57 % and were mostly below 50 % during the first two weeks, indicating weak edge after sharp upside gaps. • Result suggests that a 4 % single-day surge in MRK is typically a mean-reversion or noise event rather than the start of a persistent trend.Auto-chosen parameters 1.

Merck’s Rally Gains Traction – Position for Continued Outperformance
Merck’s 3.76% intraday surge is underpinned by regulatory wins, analyst upgrades, and robust technical momentum. The stock’s proximity to its 52-week high and overbought RSI suggest a potential pullback, but the MACD’s bullish divergence and Bollinger Band positioning favor further gains. Investors should monitor the $99.12 support level and watch for a breakout above $102.36 to confirm the trend. Meanwhile, Johnson & Johnson’s 0.45% rise highlights the sector’s mixed performance, but Merck’s leadership in oncology innovation positions it as a top-tier play. Aggressive bulls may consider MRK20251128C101 or MRK20251128C102 to capitalize on the momentum, while conservative investors should watch for a consolidation before entering long positions.
