J&J Up 18% in Three Months: Buy, Sell or Hold the Stock?

Johnson & Johnson's stock has risen 18.3% in three months, driven by strong Innovative Medicine segment growth (6.2% organic), successful new drug launches (Icotyde, Imaavy, Inlexzo), and progress on talc litigation resolution. The company targets $100 billion in 2026 revenues and expects double-digit growth excluding Stelara impact. However, J&J faces headwinds from Stelara's patent expiration, MedTech slowdown, and upcoming generic competition for other drugs. Despite these challenges, analysts recommend staying invested given the company's diversified portfolio, strong pipeline, and confident guidance.

This Healthcare Stock Barely Flinches During Market Sell-Offs

Johnson & Johnson demonstrates resilience during market downturns, with shares falling less than 2% while the S&P 500 dropped over 7%. The healthcare giant maintains strong fundamentals including 63 consecutive years of dividend increases, $94.2 billion in 2025 revenue (up 6%), and 51 drug approvals last year. However, the stock faces headwinds from tens of thousands of talc-related lawsuits and Medicare drug price negotiations under the Inflation Reduction Act.

Johnson & Johnson-Protagonist Therapeutics Partnered New Psoriasis Pill Wins FDA Nod, Shakes Up Competition With AbbVie

The FDA approved Icotyde (icotrokinra), an oral IL-23 receptor antagonist for moderate-to-severe plaque psoriasis developed by Johnson & Johnson and Protagonist Therapeutics. The approval triggers a $50 million milestone payment to Protagonist with potential for up to $580 million in additional payments. AbbVie's stock fell 5.20% as analysts view Icotyde as competitive to AbbVie's Skyrizi, though both companies believe oral therapies could expand the overall psoriasis market.

Protagonist Stock Up 120%, but One Fund Just Revealed a $170 Million Exit

Hedge fund BVF fully exited its position in Protagonist Therapeutics (PTGX), selling 2.56 million shares worth $170.12 million. Despite the stock rallying 120% over the past year, the fund's exit reflects a disciplined capital rotation strategy following the company's New Drug Application submission for rusfertide in polycythemia vera, marking a shift from clinical-stage risk to regulatory execution risk.

Sentiment note

While the stock has appreciated 120% and achieved a significant regulatory milestone with NDA submission for rusfertide, the major hedge fund exit suggests the risk-reward profile has shifted. The exit reflects profit-taking after a major milestone rather than fundamental weakness, but signals that the binary clinical risk has been replaced by regulatory and commercial execution risk.
