Best Pharmaceutical Stocks to Buy for December 2025

Kevin Voigt Updated on December 29, 2025

Eli Lilly (LLY), the Indianapolis-based drugmaker, recently made news by becoming the first pharmaceutical company to top $1 trillion in market value, thanks in part to its breakout weight-loss drugs, Mounjaro and Zepbound. Are other pharma stocks worth a look?

Are Pharmaceutical Stocks a Good Investment?

Pharmaceutical firms have long been viewed as a blend of defensive income plays and growth opportunities. As demand for medicines, vaccines, and chronic-disease treatments remains steady regardless of economic cycles, pharma companies often deliver stable earnings. That stability — combined with generous dividends many pharma companies pay — makes them especially attractive when the broader market is choppy or inflation is high.

Additionally, the global pharmaceutical industry continues to grow: Analysts expect the sector to expand over the coming years, aided by rising demand for treatments for chronic illnesses, oncology, vaccines and demographic factors such as aging populations.

However, pharmaceutical investing isn’t risk-free. Outcomes often depend on R&D success, regulatory approvals, patent expirations, and competitive pressures. That’s why smart investors often balance stable dividend-payers with growth-oriented firms or diversify across multiple names.

Here, we analyze and rank the best pharmaceutical stocks to buy now ranked on a blend Zacks Rank signals, Style Scores and fundamentals:

Style Scores

The Style Scores are a complementary set of indicators to use alongside the Zacks Rank. It allows the user to better focus on the stocks that are the best fit for his or her personal trading style.

The scores are based on the trading styles of Value, Growth, and Momentum. There's also a VGM Score ('V' for Value, 'G' for Growth and 'M' for Momentum), which combines the weighted average of the individual style scores into one score.

Value Score A

Growth Score A

Momentum Score A

VGM Score A

Within each Score, stocks are graded into five groups: A, B, C, D and F. As you might remember from your school days, an A, is better than a B; a B is better than a C; a C is better than a D; and a D is better than an F.

As an investor, you want to buy stocks with the highest probability of success. That means you want to buy stocks with a Zacks Rank #1 or #2, Strong Buy or Buy, which also has a Score of an A or a B in your personal trading style.

Earnings ESP Zacks Earnings ESP (Expected Surprise Prediction) looks to find companies that have recently seen positive earnings estimate revision activity. The idea is that more recent information is, generally speaking, more accurate and can be a better predictor of the future, which can give investors an advantage in earnings season. The technique has proven to be very useful for finding positive surprises. In fact, when combining a Zacks Rank #3 or better and a positive Earnings ESP, stocks produced a positive surprise 70% of the time, while they also saw 28.3% annual returns on average, according to our 10 year backtest.

Projected EPS Growth: 32.06%
Last Quarter EPS Growth: 28.07%
Last EPS Surprise: 23.73%
Next EPS Report date: Feb. 4, 2026

Our Take:

Phibro Animal Health produces vaccines, medicated feed additives, and nutritional solutions for food and companion animals, providing exposure to livestock demand alongside an expanding pet-care platform. In the first quarter of fiscal 2026, net sales and gross profit increased sharply, and management raised fiscal 2026 guidance as integration synergies emerged.

Strategically, the acquisition of Zoetis’ medicated-feed-additive and water-soluble portfolios enhances scale, global reach, and cash-flow stability. A new canine periodontal licensing deal adds optionality in higher-margin companion animal care.

A Zacks Rank #1 (Strong Buy) mirrors fresh positive estimate revisions. Style Scores of A for Value and B for Growth suggest attractive entry points with improving earnings power, while a C for Momentum implies the market is waiting for consistent execution. On the Price, Consensus & EPS Surprise chart, the stock’s uptrend aligns with rising 2026–2027 EPS lines and recent beats, though swings around results hint at above-average volatility.

Next EPS Report date:Feb. 27, 2026

Our Take:

ANI Pharmaceuticals develops rare-disease therapies alongside a durable U.S.-based generics platform, anchored by Purified Cortrophin Gel and a growing retina franchise that includes ILUVIEN and YUTIQ.

Recent results show strong execution. In Q3 2025, revenue rose 54% as Cortrophin Gel nearly doubled, driving record EBITDA and another full-year guidance raise. A royalty buyout on ILUVIEN/YUTIQ improves economics going forward. These trends point to operating leverage and a more profitable mix as rare disease approaches roughly half of sales.

A Zacks Rank #1 captures upward estimate revisions. Style Scores of A for Growth and Momentum align with accelerating earnings and price strength, while a B Value Score suggests investors are paying a reasonable multiple for that trajectory. On the chart, shares trend higher as 2026–2027 EPS lines stair-step up. Repeated positive surprises through 2024–2025 and a fresh estimate “step-up” preceded the latest breakout after a mid-2024 pause, reinforcing an execution-driven rerating.

Our Take:

Collegium Pharmaceutical is a specialty biopharma focused on responsibly managed pain and CNS care, led by Xtampza ER, Belbuca, and the Nucynta franchise, with ADHD therapy Jornay PM providing diversification.

Fundamentals strengthened after a record third-quarter 2025, with the company delivering record revenue and adjusted EBITDA, supported by double-digit growth in the pain portfolio and a record Jornay PM contribution. The company again raised 2025 guidance, maintained a strong cash position, continued deleveraging, and repurchased shares, underscoring balance-sheet strength and disciplined capital allocation.

A Zacks Rank #1 reflects positive estimate revisions. Value Score of A indicates the stock screens attractively versus fundamentals, but the D Growth and F Momentum scores flag decelerating growth metrics and choppy trading. On the chart, shares trend higher from mid-2024 as 2025–2026 EPS estimates rise. Spikes around earnings underscore event risk, yet the steadily climbing consensus lines suggest estimates are doing most of the work supporting the move.

Our Take:

Theravance Biopharma develops respiratory and neurogenic therapies, led by YUPELRI, a nebulized LAMA for COPD partnered with Viatris, and ampreloxetine for neurogenic orthostatic hypotension.

Fundamentals look sturdier this year. In Q3 2025, the company reported record YUPELRI sales, recognized by Viatris, and non-GAAP breakeven in Q3. With a cash balance above $330 million and no debt, Theravance has room to advance programs without dilutive urgency. The pivotal CYPRESS readout for ampreloxetine remains on track for early 2026.

A Zacks Rank #2 reflects positive estimate revisions, while a Style Score of A for Growth and B for Momentum align with improving profitability and execution. The C Value Score suggests shares aren’t optically cheap but remain reasonable against growth prospects. On the chart, EPS estimates for 2026–2027 have stepped up, and the stock has trended higher alongside revisions, albeit with pronounced swings around quarterly updates.

Our Take:

Enliven Therapeutics is a clinical-stage oncology company developing small-molecule kinase inhibitors, led by ELVN-001 for BCR-ABL–driven chronic myeloid leukemia. Updated Phase 1 data presented at EHA 2025 showed encouraging efficacy and tolerability in heavily pretreated CML, including patients previously treated with asciminib, supporting potential differentiation.

Recent results underscored solid execution and financial strength, with randomized Phase 1b enrollment completed, plans to initiate a Phase 3 pivotal trial in 2026, and $478 million in cash and securities providing runway into the first half of 2029, reducing near-term financing risk.

A Zacks Rank 2 reflects positive estimate revisions, while the B Momentum Score aligns with improving sentiment; C for Growth and D for Value suggest investors are paying for optionality ahead of pivotal work. On the chart, shares have recovered from 2024 lows and track gradually rising 2026–2027 EPS lines, though periodic swings around data events underscore typical small-cap pharma volatility.

Methodology

The Zacks Rank is a proprietary stock-rating model that uses trends in earnings estimate revisions and earnings-per-share (EPS) surprises to classify stocks into five groups: #1 (Strong Buy), #2 (Buy), #3 (Hold), #4 (Sell) and #5 (Strong Sell). The Zacks Rank is calculated through four primary factors related to earnings estimates: analysts' consensus on earnings estimate revisions, the magnitude of revision change, the upside potential and estimate surprise (or the degree in which earnings per share deviated from the previous quarter).

Zacks builds the data from 3,000 analysts at over 150 different brokerage firms. The average yearly gain for Zacks Rank #1 (Strong Buy) stocks is +23.62% per year from January, 1988, through June 2, 2025.

Selections for Best Pharmaceutical Stocks are based on the current top ranking stocks based on Zacks Indicator Score and other factors. For this list, only companies that have average daily trading volumes of 100,000 shares or more are considered. All information is current as of market open, Dec. 29, 2025.

What are Pharmaceutical Stocks?

“Pharmaceutical stocks” refer to publicly traded companies engaged primarily in the discovery, development, manufacturing, and sale of drugs — including brand-name medicines, biologics, vaccines and sometimes generics.

Types of Pharmaceutical Stocks

Large-cap, established pharmaceutical companies – These are the global leaders with diverse drug portfolios, steady revenue streams, and long histories of paying dividends. Examples include Pfizer (PFE), Merck (MRK), Johnson & Johnson (JNJ), AbbVie (ABBV), Bristol-Myers Squibb (BMY) and Novartis (NVS). These companies tend to have well-funded pipelines and wide geographic reach, making them popular with conservative investors.

Specialty-drug and focused biopharma firms – These companies concentrate on specific therapeutic areas such as rare diseases, oncology, immunology, or metabolic conditions. They can deliver strong growth if a breakthrough therapy succeeds. Examples include Vertex Pharmaceuticals (VRTX) in genetic diseases, Regeneron (REGN) in immunology and ophthalmology, Incyte (INCY) in oncology and Horizon Therapeutics (HZNP) in autoimmune disorders.

Pipeline-driven or R&D-intensive pharmaceutical developers – These companies may have fewer commercialized drugs but invest heavily in research, clinical trials, and next-generation treatments. Revenue may be uneven, but the upside can be significant if major approvals come through. Notable examples include Moderna (MRNA) in mRNA therapeutics, BioNTech (BNTX) in immuno-oncology, Alnylam Pharmaceuticals (ALNY) in RNA interference drugs and Sarepta Therapeutics (SRPT) in genetic therapies.

Pros of Pharmaceutical Stocks

Consistent demand for medicines: Healthcare needs remain steady regardless of economic cycles, helping companies like Merck, Eli Lilly (LLY), or AstraZeneca (AZN) maintain dependable revenue.
Attractive dividends: Many large pharmaceutical companies, such as Pfizer, AbbVie, and Johnson & Johnson, are known for long-standing dividend programs and high payout reliability.
Potential for major upside from drug launches: A successful approval or breakthrough therapy—such as Eli Lilly’s diabetes/obesity drugs or Regeneron’s eye-disease treatments—can significantly boost a company’s valuation.
Diversification within healthcare: Pharma stocks often behave differently from technology, consumer, or financial sectors, providing balance to an investment portfolio.

Cons of Pharmaceutical Stocks

Regulatory hurdles: Failure to secure FDA approval, clinical-trial setbacks, or safety concerns can sharply impact valuations when trials don’t meet expectations.
Patent cliffs and generic competition: Once exclusivity ends, branded drugs can face rapid erosion from generics or biosimilars. For instance, AbbVie’s Humira — once the world’s top-selling drug — saw sales drop after biosimilar competition entered the market.
Competitive pressures: New drugs from rivals can displace existing blockbusters. For example, Novo Nordisk (NVO) and Eli Lilly (LLY) dominate the obesity/diabetes segment, squeezing competitors.
High research costs and uncertainties: Pharma R&D is expensive and unpredictable. Firms like Moderna, Alnylam, or Sarepta often experience stock volatility tied directly to clinical-trial outcomes or scientific feasibility.

Best Pharmaceutical Stocks vs. Biotechnology Stocks: Which Is Better?

Pharmaceutical companies (large-cap pharma)
These firms—such as Merck, Pfizer, AbbVie, and Novartis—tend to be more stable due to established product lines and recurring revenue. They typically appeal to income-focused investors because they often pay strong and consistent dividends.

Biotechnology companies
Biotech firms like Regeneron, Vertex, Moderna, and BioNTech often target cutting-edge scientific approaches with high growth potential. Their revenues can surge when a breakthrough therapy succeeds, but they face much greater volatility and dependency on research outcomes.

Which is better?

If you prefer steady dividends and lower volatility, large U.S. and international pharma names are generally a better fit.
If you’re seeking high potential returns and can handle larger price swings, biotech and R&D-intensive drug developers may offer superior upside.
Many investors blend both categories to balance income with innovation-driven growth.

Risks and Safety

How do FDA approvals impact stock prices?

Securing FDA approval for a new drug can be a major catalyst: positive news can dramatically boost stock price. Conversely, delays, negative trial results, or regulatory setbacks can result in sharp declines. That’s why even solid firms factor in “uncertainty rating” — because much hinges on regulatory success.

How do patent expirations affect pharmaceutical stocks?

When a drug’s patent expires, generics may enter, often severely reducing sales for the original drug — which can lead to revenue decline unless the company successfully replaces the lost revenue with new drugs or therapies.

What are the biggest risks when investing in drug companies?

R&D failure and sunk costs.
Regulatory hurdles and unpredictable approval processes.
Competition (generics, biosimilars, newer therapies).
Litigation, pricing pressure, changes in healthcare policy and regulation.
Concentration risk if a company relies heavily on a few blockbuster drugs.

Pharmaceutical Stocks Trends

Which pharmaceutical stock benefits the most from aging population trends?

Large-cap companies with broad portfolios — especially those offering treatments for chronic diseases (e.g., cardiovascular, cancer, auto-immune, diabetes) — tend to benefit from demographic trends. Firms like Merck, AbbVie, and others with diversified pipelines may be especially well positioned.

How have pharmaceutical stocks performed in the last 5 years?

Many large-cap pharma stocks have offered attractive dividend yields and moderate growth, often outperforming more cyclical sectors, especially in volatile markets. Their relative resilience and dividends have appealed to investors seeking stability.

Are pharma stocks recession-proof?

Not entirely — but compared with consumer discretionary or cyclical sectors, pharma tends to be more resilient. Demand for essential medicines tends to remain stable even during economic downturns, giving pharma a defensive characteristic.

How to Invest in Pharmaceutical Stocks

Should beginners invest in pharma ETFs instead of single stocks?

Yes — for many retail investors, pharma-focused ETFs (or broader healthcare ETFs) offer diversified exposure, reducing the risk of overconcentration in a single company. This mitigates risks like regulatory failure or drug-specific setbacks.

Is it better to invest in global or U.S. pharmaceutical companies?

Both have advantages. U.S. firms often lead in innovation, R&D, and large-scale global distribution. International companies may offer exposure to different markets, drug pipelines, and potentially attractive valuations. A mix of both can provide balanced diversification.
