Merck’s explosive rally on November 25, 2025, has captured market attention as the stock surges 4.06% intraday, driven by regulatory milestones and analyst upgrades. The FDA’s approval of Keytruda in bladder cancer and Wells Fargo’s bullish price target have ignited momentum, pushing MRK to a 52-week high of $105.068. With options liquidity surging and technical indicators flashing bullish signals, the pharma giant’s rally appears poised for a continuation.

FDA Approval and Wells Fargo Upgrade Ignite Merck's Rally
Merck’s 4.06% intraday surge is directly tied to two catalysts: the FDA’s approval of Keytruda (pembrolizumab) in combination with Padcev for cisplatin-ineligible muscle-invasive bladder cancer and a Wells Fargo upgrade. The FDA clearance expands Keytruda’s therapeutic footprint, reinforcing Merck’s leadership in oncology. Simultaneously, Wells Fargo raised its price target to $125, citing a post-Keytruda growth story. These developments validate Merck’s pipeline resilience and investor confidence, propelling the stock to a 52-week high.

Pharma Sector Gains Momentum as Merck Leads Charge
The pharmaceutical sector (SPDR S&P Pharmaceuticals ETF: XLV) has gained 0.72% alongside Merck’s rally, with sector leader Johnson & Johnson (JNJ) up 0.98%. Merck’s outperformance underscores its unique positioning in oncology innovation, particularly with Keytruda’s expanding indications. While JNJ’s modest gains reflect broader sector strength, Merck’s 4.06% move highlights its ability to capitalize on regulatory and analyst-driven momentum.
