Argenx Soars 2.78% on Regulatory Wins and Analyst Optimism: A Biotech Breakout in the Making?

Summary
• RBC Capital raises ARGX price target to $925, signaling 'Outperform' confidence
• UK MHRA grants Vyvgart approval for CIDP, boosting shares 2%
• UBS and Jefferies maintain Buy ratings despite mixed clinical trial outcomes

Argenx (ARGX) surged 2.78% to $875.07 in a volatile session, trading between $859.24 and $878.06. The rally follows a flurry of analyst upgrades, regulatory approvals, and bullish revenue forecasts, positioning the biotech giant at a pivotal inflection point as its pipeline accelerates toward commercialization.

Regulatory Green Light and Analyst Hype Fuel Argenx's Surge
Argenx’s intraday rally was catalyzed by the UK Medicines and Healthcare products Regulatory Agency (MHRA) granting Vyvgart approval for chronic inflammatory demyelinating polyneuropathy (CIDP), a rare autoimmune disorder. This regulatory win, combined with RBC Capital’s 7.56% price target increase to $925 and Stifel’s $1,248 target, underscored growing confidence in Vyvgart’s commercial potential. Despite the Phase III TED trial discontinuation for thyroid eye disease, analysts like RBC’s Luca Issi emphasized Vyvgart’s dominance in myasthenia gravis (MG) and chronic inflammatory demyelinating polyneuropathy (CIDP), projecting $1.24 billion in Q4 2025 sales. The stock’s 57.46% six-month gain reflects a market betting on a $10 billion revenue trajectory by 2030.

Biotech Sector Rally as AMGN Leads Gains
The broader biotech sector mirrored Argenx’s momentum, with Amgen (AMGN) rising 0.85% as a sector leader. While AMGN’s growth stems from its blockbuster oncology and immunology franchises, Argenx’s 2.78% surge highlights its niche focus on autoimmune therapies. The sector’s 194.09% five-year return underscores investor appetite for innovation, with Argenx’s 52-week high of $934.62 and 92.98% revenue growth outpacing peers like Immunovant (IMVT) and Ascendis Pharma (ASND).

Navigating Argenx’s Volatility: ETFs and Options for the Bullish Play
• 200-day MA: $682.65 (well below current price)
• RSI: 22.89 (oversold territory)
• MACD: 0.73 (bullish divergence from signal line 11.04)
• Bollinger Bands: $858.62 (lower band) vs. $943.79 (upper band)

Argenx’s technicals suggest a short-term rebound after hitting oversold RSI levels and a bullish MACD crossover. Key resistance lies at the 200-day MA ($682.65) and the 30-day support zone ($888.39–$890.36). While no leveraged ETFs are available, the stock’s 52.88x P/E and 92.98% revenue growth justify a bullish stance. With RBC’s $925 target and Stifel’s $1,248 projection, aggressive bulls could consider a 5% upside scenario to $919.32. However, the absence of liquid options limits direct leverage, making a core holding in a diversified biotech portfolio the most prudent approach.

Backtest argenx Stock Performance
The backtest of ARGX's performance following a 3% intraday increase from 2022 to the present shows favorable results. The 3-day win rate is 50.70%, the 10-day win rate is 57.34%, and the 30-day win rate is 66.40%, indicating a higher probability of positive returns in the short term. The maximum return during the backtest was 8.35% over 30 days, suggesting that while there is volatility, ARGX can offer decent gains within a month after an intraday surge.

Argenx at a Tipping Point: Hold for the Long Game or Cash in on the Rally?
Argenx’s 2.78% surge reflects a market betting on Vyvgart’s commercial dominance and a $10 billion revenue ceiling by 2030. With RBC and Stifel projecting $925–$1,248 price targets and the stock trading 23% above its 200-day MA, the near-term outlook remains bullish. Investors should monitor the 200-day MA ($682.65) as a critical support level and watch for a breakout above $934.62 (52-week high). Meanwhile, Amgen’s 0.85% rise as a sector leader reinforces the biotech sector’s strength. For those with a high-risk tolerance, a core position in Argenx could capitalize on its pipeline-driven growth, but conservative traders may prefer to wait for a pullback to the Bollinger Band lower bound ($858.62) before entering.
