Madrigal Soars 10.2% on Record Rezdiffra Sales and Strategic GLP-1 Move

Summary
• Madrigal’s MDGL stock surges 10.2% intraday, hitting a 52-week high of $496.98
• Q3 Rezdiffra net sales jump to $287.3M, validating a $1B+ annualized run rate
• Licensing of MGL-2086 GLP-1 asset drives $174M R&D spend, signaling aggressive combo therapy push

Madrigal Pharmaceuticals (MDGL) delivered a seismic intraday rally, surging 10.2% to $490.00 amid record-breaking Rezdiffra sales and a strategic pivot into combination therapy. The stock’s 44-point swing from $446.20 to $496.98 reflects investor confidence in the company’s MASH market dominance and long-term IP security. With a $1.1B cash runway and a new 2045 patent, MDGL’s aggressive capital allocation strategy is now front and center.

Rezdiffra’s Commercial Velocity and GLP-1 Licensing Ignite Bullish Sentiment
MDGL’s 10.2% surge stems from two catalysts: record-breaking Rezdiffra sales and a strategic licensing move. Q3 net sales of $287.3 million—up 360% year-over-year—validated a $1.1B annualized run rate, driven by 29,500 patients and 10,000 prescribers. Simultaneously, the $174M R&D spend for MGL-2086, a global GLP-1 asset, signals a preemptive strike to control the MASH combination therapy market. This dual focus on revenue acceleration and IP extension into 2045 has redefined investor expectations, justifying the stock’s 52-week high.

Pharma Sector Mixed as J&J Slides, MDGL Defies Trend
While MDGL’s rally is self-driven by product and IP milestones, the broader pharmaceutical sector showed mixed signals. Sector leader Johnson & Johnson (JNJ) fell 0.35% on earnings updates, contrasting MDGL’s momentum. However, MDGL’s aggressive R&D and commercial spend align with peers like Gilead and AbbVie, which are also prioritizing pipeline expansion over short-term profitability. The divergence highlights MDGL’s unique position in the high-growth MASH space.

Bullish Setup: ETFs and Options for MDGL’s Breakout Trajectory
• 200-day average: 347.56 (well below current price)
• RSI: 54.33 (neutral, no overbought/oversold)
• MACD: -0.83 (bullish divergence as price rises)
• Bollinger Bands: Price at 490.00, above upper band of 447.60

MDGL’s technicals confirm a short-term bullish trend, with the 52-week high at 496.98 acting as a key resistance. The stock’s 10.2% intraday surge suggests momentum traders are capitalizing on the breakout. For options, the MDGL20251219C470 call stands out: it offers a 19.56% leverage ratio, 78.77% delta, and 16.61% implied volatility, with $25,000 turnover ensuring liquidity. A 5% upside to $514.50 would yield a payoff of $44.50 per contract, aligning with the stock’s current trajectory. This option’s high gamma (0.010167) and theta (-0.420177) make it ideal for short-term bets. Aggressive bulls should target a break above $496.98 to confirm the 52-week high as a new support level.
