Best healthcare and pharma stocks: how to pick them with data
Updated June 17, 2026 · DeepTicker
If you're hunting for the best healthcare and pharma stocks, the first thing worth knowing is that you're looking at one of the most profitable and, at the same time, most complex sectors in the market: it combines patents that act as mini-monopolies, very high margins and demand that doesn't vanish in recessions, but also clinical trials that can fail overnight. This guide is educational, not a buy list: you'll learn to identify, analyze and filter healthcare companies with data, understanding what really matters (the patent, the R&D pipeline, the margins and the moat) and which risks to watch. It's educational information so you decide for yourself with judgment, not financial advice.
The healthcare sector is enormous and very heterogeneous, and that's the first mistake a novice investor makes: lumping together realities that have nothing in common. Within "healthcare" live at least five different families. The big pharma companies (Big Pharma, such as Pfizer, Johnson & Johnson or Novartis) sell already-approved drugs and generate cash in spades. The biotechs range from established giants to companies that don't yet bill a dollar and burn cash developing a single drug. The makers of medical equipment and devices (Medtronic, Stryker) sell surgical material, prosthetics or insulin pumps. The insurers and health managers (UnitedHealth) work more like financial companies. And the distributors and pharmacy chains work on razor-thin margins over huge volumes. Analyzing the sector well starts with knowing which of these families you're in.
How does a pharma company really make money? The key is the patent. When a company discovers and approves a drug, it receives a patent that gives it the exclusive right to sell it for about 20 years (of which, after subtracting the trial years, 10 to 14 years of effective sales usually remain). During that period no one else can manufacture that active ingredient, so the company can set prices far above the cost of production. A pill that costs cents to make sells for tens or hundreds of dollars. That's where the sector's typical gross margins of 70-90% come from. The patent is a textbook moat: a competitive advantage protected by law that keeps the competition out.
That's why the healthcare sector is so attractive for a long-term portfolio. First, demand is inelastic and defensive: people don't stop taking their blood-pressure medication because there's a recession, so revenue is more stable than in cyclical sectors. Second, the aging of the population in Europe, the US and China is a structural tailwind lasting decades: more elderly people means more consumption of drugs, prosthetics and health services. Third, the best companies generate enormous, recurring cash flows that they reinvest in research or pay out as growing dividends. Many pharma companies are "dividend aristocrats" precisely because of this combination of abundant cash and resilient demand.
But that same model hides its great Achilles' heel: the patent expires. The day it does, the generics makers enter the market and the drug's price collapses 80-90% within months. That moment is called the patent cliff, and it can wipe out half the revenue of a blockbuster drug at a stroke. A pharma company that depends on a single drug with the patent about to expire is a time bomb, however pretty its current profits may look. That's why picking the best healthcare and pharma stocks isn't about buying the one that earned the most last year, but about telling the company with an R&D pipeline capable of replenishing what expires apart from the one living off the income of a past success that's about to evaporate.
What to look at to pick the best healthcare and pharma stocks
The first filter is the pipeline: the portfolio of drugs the company has in development and what phase they're in. A drug goes through Phase I (safety in a few volunteers), Phase II (efficacy in hundreds of patients) and Phase III (efficacy and safety in thousands, the decisive and very expensive step) before applying for approval from the regulator (the FDA in the US, the EMA in Europe). The more advanced and broader the pipeline, the less the company depends on a single product. A good pharma company has several Phase III candidates spread across different therapeutic areas (oncology, cardiology, immunology), so that the failure of one doesn't sink the ship. Pipeline diversification is, in healthcare, what customer diversification is in other sectors.
The second filter is dependence on the patent. It's worth looking at what percentage of revenue comes from the few blockbuster drugs and when their patents expire. If 40% of billings depend on a drug whose patent expires within two years and there's nothing equivalent in the pipeline, the risk is very high. The third filter is the quality of the balance sheet and cash generation: R&D is very expensive (a new drug can cost more than a billion dollars and ten years of work), so only companies with abundant cash and little debt can sustain research without diluting their shareholders. In DeepTicker, the DeepTicker Score sums up quality and solvency in a grade from 0 to 100 compared with the sector itself, so you see at a glance whether a pharma company is Elite, Solid or Fragile versus its rivals.
The metrics that matter most in healthcare and pharma
Beyond the pipeline, there's a handful of metrics that separate quality healthcare companies from the rest. The gross margin and the operating margin tell you how much pricing power the business has: a pharma company with strong patents shows gross margins of 75-85%, while a drug distributor barely scrapes 3-5%. The ROIC (return on invested capital) measures whether the company genuinely turns research into sustainable profit; it's a key metric of quality analysis because a high, stable ROIC over the years is the fingerprint of a real moat, not of a lucky break. The R&D spend over sales (often 15-20% in pharma) indicates how much it reinvests in its future: too little and it'll run out of products; too much and it may be burning cash with no return.
To judge the price, the P/E alone isn't enough, because a biotech in the middle of a launch can perfectly justify a P/E of 40 and another a P/E of 12 that's a trap for having the patent about to expire. This is where discounted-cash-flow valuation comes in: instead of guessing how much the stock is "worth", DeepTicker's Reverse DCF asks the question in reverse and calculates what growth the current price is discounting. If a pharma company trades at $372 and today grows 12% a year, but the price is only justified if it grows 18% for ten years and lifts its cash margin from 20% to 32%, you decide whether you believe those two requirements knowing its pipeline. Also, the system uses the real cost of capital by industry (in healthcare and pharma it usually hovers around 7-8%, not a generic 8.5%), which changes the estimated value by between 15% and 30%.
Healthcare-sector risks you need to watch
Risk number one is the regulatory and clinical. A drug that looked promising can fail in Phase III and, in a single day, make the stock drop 30, 40 or 50%. Likewise, an FDA or EMA refusal to approve a drug, or the withdrawal of one already on the market for side effects, can be devastating. This affects above all the small biotechs, which often bet everything on a single candidate: that's why a company with no revenue and dependent on a single drug is speculation, not investment, and it's worth knowing before you go in.
The second great risk is the patent cliff already mentioned: the expiry of patents and the entry of generics. The third is the political and pricing risk: in the US, the world's largest pharmaceutical market, drug prices are a recurring subject of political debate, and any law that forces them down hits the margins of the whole sector at once. To this is added the risk of litigation (lawsuits over side effects can cost billions) and, in biotech, the risk of dilution: companies that burn cash issue new shares constantly to fund themselves, reducing the percentage of each existing shareholder. DeepTicker is honest about these cases: for a biotech with no revenue, the classic Reverse DCF doesn't apply, so the system warns you and tells you what to look at instead (pipeline, cash on hand, burn rate) rather than handing you a misleading number.
How to find healthcare stocks with good fundamentals using a screener
Reviewing hundreds of pharma and healthcare companies by hand is unfeasible. This is where a good screener (stock filter) changes the rules of the game. DeepTicker's stock screener lets you sift through thousands of companies with more than 140 filters and apply ready-made strategy presets, like the Graham style (classic value) or Greenblatt's Magic Formula (quality + price). For the healthcare sector you can combine criteria like a gross margin above 60%, ROIC above 15%, net debt to EBITDA below 2x and sustained revenue growth, to keep only the companies that genuinely combine quality and financial strength.
Once the list is filtered, the work isn't over: you have to open the page for each company to understand the business behind the numbers. On the stock pages you'll see at a glance the DeepTicker Score for quality, the Reverse DCF valuation verdict (Bargain, Reasonable, Demanding, Expensive or Priced-in bubble) and the figures explained one by one, no black boxes. That's DeepTicker's philosophy: widely recognized fundamental-analysis methods, made simple so anyone can invest with judgment, and designed so that the more you use it, the more you learn about finance almost without realizing it.
Healthcare and pharma: quality versus price
Finding a quality pharma company (good pipeline, high margins, patent moat, high ROIC) is only half the job. The other half is not overpaying for it. An excellent company bought at an absurd price can be a terrible investment for years, because the price already discounts all the future good news. That's why it's worth mentally separating two distinct questions: is the company good? (quality) and is it cheap or expensive today? (price). DeepTicker separates them with two tools: the DeepTicker Score answers the first (quality and competitive-advantage analysis, moat and ROIC) and the Reverse DCF answers the second (discounted-cash-flow valuation).
There's still a third question that adds perspective: is there a franchise and is the price sustainable? Value analysis calculates the EPV (the value of current earnings assuming no growth at all) and compares it with what it would cost to replicate the company from scratch; if the first is larger, there's a real franchise. And it applies a simple mathematical rule: if the growth the price is discounting persistently exceeds the cost of capital (G ≥ R), the price isn't rational, it's "a priced-in miracle". For a mature pharma company with solid patents, this test helps tell the one that's expensive but defensible apart from the one trading in pure euphoria. By combining quality, price and franchise you get a complete picture, not a hunch.
Choosing well in the healthcare sector isn't about guessing which drug will succeed, but about applying a method: separating the quality of the business (pipeline, margins, patent moat) from its price and its franchise, with a rigorous method made simple. With DeepTicker you filter the whole sector with more than 140 criteria, see the DeepTicker Score for quality and the Reverse DCF verdict of each company, and learn finance while you decide.

Frequently asked questions
What are the best pharma stocks to invest in?
There's no universal list of "the best", because it depends on your horizon, your risk tolerance and, above all, the price they trade at today. What's useful is learning to identify them: look for companies with a diversified pipeline, high gross margins, high ROIC and little dependence on a single patent. This is educational information, not a buy recommendation.
How do I pick healthcare stocks with good fundamentals?
Look at the quality of the balance sheet (little debt, abundant cash to sustain R&D), high operating margins and a high, stable ROIC over time. A screener lets you filter the sector by these criteria in seconds and keep only the solid companies before analyzing them one by one.
What's the difference between a pharma company and a biotech?
Broadly, a big pharma company already sells approved drugs and generates cash, while many biotechs are still developing their product and may bill nothing. The biotech with no revenue is far riskier and more speculative: it bets almost everything on its drug passing the clinical trials.
Why do patents matter so much in pharma stocks?
The patent gives the company the exclusive right to sell a drug for about 20 years, which lets it charge very high prices without competition. It's its main moat. The problem comes when it expires (the patent cliff): the generics enter and the revenue of that drug can collapse 80-90% within months.
Are pharma companies defensive stocks?
In general yes, because demand for drugs doesn't vanish in recessions, which gives stable revenue and recurring dividends. But beware: small, speculative biotechs are not defensive at all; they can drop 50% in a day if a clinical trial fails. It pays to tell them apart within the sector.
How do I know if a pharma stock is cheap or expensive?
The P/E alone misleads in this sector. A finer method is the Reverse DCF, which calculates what growth the current price is discounting and lets you judge whether it's credible knowing its pipeline. In DeepTicker you'll see that verdict summed up as Bargain, Reasonable, Demanding, Expensive or Priced-in bubble.
What risks do undervalued pharma stocks have?
A pharma company can look cheap precisely because the market anticipates the expiry of a key patent, an empty pipeline or a major lawsuit. Before taking the low price as a bargain, check that there isn't an underlying reason that justifies the discount. Sometimes the cheap thing is cheap for a reason.
Can I analyze pharma stocks on DeepTicker for free?
Yes. My Portfolio and the Contest are free forever, and you have a 14-day trial with no card to use the screener with more than 140 filters, the DeepTicker Score and the Reverse DCF valuation on any healthcare stock in the US, Europe, the UK or China.
