What are the top health insurance stocks to watch? What do you need to know before investing in them? As the major health insurers might say, “We've got you covered.”
Top health insurance stocks for 2025
Here are four publicly traded health insurance companies and one exchange-traded fund (ETF) likely to perform well over the long term:
| Name and ticker | Market cap | Dividend yield | Industry |
|---|---|---|---|
| UnitedHealth Group (NYSE:UNH) | $305.0 billion | 2.59% | Healthcare Providers and Services |
| Elevance Health (NYSE:ELV) | $80.1 billion | 1.90% | Healthcare Providers and Services |
| CVS Health (NYSE:CVS) | $102.6 billion | 3.29% | Healthcare Providers and Services |
| Centene (NYSE:CNC) | $19.9 billion | 0.00% | Healthcare Providers and Services |
| iShares Trust - iShares U.s. Healthcare Providers ETF (NYSEMKT:IHF) | $0.0 million | 0.00% | Capital Markets |
1. UnitedHealth Group
NYSE: UNH
Key Data Points
UnitedHealth Group (UNH +2.55%) ranks as the biggest health insurer in the world by far. Its UnitedHealthcare business unit offers health plans for employers and individuals. It's also a major player in the markets for Medicare Advantage, Medicare supplemental plans, and Medicaid.
The company's Optum business segment provides information- and technology-enabled health services, including OptumRx pharmacy benefits management (PBM) services. While UnitedHealthcare generates around three-fourths of the company’s total revenue, Optum has been a key growth driver for UnitedHealth Group in the past.
Some of UnitedHealth Group's growth in recent years has been driven by acquisitions. For example, the big healthcare company acquired Change Healthcare in October 2022.
More recently, UnitedHealth closed its $3.3 billion purchase of home health and hospice provider Amedisys in August 2025.
2. Elevance Health
NYSE: ELV
Key Data Points
Although Elevance Health (ELV +5.73%) is only a fraction of the size of UnitedHealth Group in terms of market capitalization, it's still one of the largest health insurers. Elevance, formerly known as Anthem, operates Blue Cross and/or Blue Shield plans in 14 states but is licensed to sell health insurance throughout the country.
It competes in the same arenas as UnitedHealth Group, with offerings that include employer-sponsored and individual health plans, Medicare Advantage, Medicare supplements, and Medicaid. Elevance Health's other businesses include pharmacy benefits manager CarelonRx and Carelon Services, which provides healthcare services that include behavioral health, health and wellness programs, integrated care delivery, palliative care, and utilization management.
Elevance's health benefits segment, which includes the company's individual, employer group, BlueCard, Medicare, Medicaid, and federal health businesses, generates more than 80% of total revenue. However, Carelon Services is its fastest-growing unit.
3. CVS Health
NYSE: CVS
Key Data Points
You might think of CVS Health (CVS +2.29%) as just a pharmacy retailer, but the company also runs CVS Caremark, one of the largest PBMs in the country. Thanks to its 2018 acquisition of Aetna, CVS Health is a top health insurer, too.
The company's healthcare benefits segment, which consists mainly of Aetna, generates more than one-third of CVS' total revenue. The segment's revenue has grown rapidly, driven primarily by its Medicare and commercial insurance products.
Although several of these top health insurance companies pay dividends, CVS Health offers the most attractive dividend yield in the group.
4. Centene
NYSE: CNC
Key Data Points
Centene (CNC +4.73%) focuses largely on the Medicaid market. Traditional participants (including those in the Children's Health Insurance Program and Temporary Assistance for Needy Families program) and participants who need frequent monitoring make up more than half of the company's total membership base. Centene's Medicaid plans generate a little over half of the company's total revenue.
Medicaid remains a solid business for Centene. However, its Medicare and commercial insurance businesses are growing at much faster rates.
Centene is especially targeting two areas for future growth -- individuals who are eligible for both Medicare and Medicaid (known as dual eligibles) and the Individual Coverage Health Reimbursement Arrangement (ICHRA), which is an alternative to group insurance.
5. iShares U.S. Healthcare Providers ETF
NYSEMKT: IHF
Key Data Points
One way to scoop up shares of these top health insurance stocks -- plus others -- is to buy shares in an exchange-traded fund (ETF). Although no ETF focuses solely on health insurers, the iShares U.S. Healthcare Providers ETF (IHF +2.23%) comes close.
The ETF tracks the performance of the Dow Jones U.S. Select Healthcare Providers index, which includes U.S. companies that provide health insurance, diagnostics, and specialized treatment. UnitedHealth Group, CVS Health, Cigna Group (CI +3.62%), and HCA Healthcare (HCA +2.91%) are the four largest holdings of this fund.
There are two primary downsides to buying the iShares U.S. Healthcare Providers ETF compared to investing directly in the top health insurance stocks. First, if your goal is to invest only in health insurance, the ETF isn't a good fit because of its other holdings. Second, you'll have to pay annual expense fees. The iShares U.S. Healthcare Providers ETF's expense ratio is currently 0.38%.
What to look for in health insurance stocks
There are some metrics, such as revenue and earnings growth, that you should evaluate no matter what kind of stock you're buying. There are also a few specific factors to consider when you're choosing health insurance companies on the stock market:
- Revenue mix: Understanding a company's revenue mix -- how it generates most of its revenue -- can give you a better idea of its growth prospects and weaknesses. Some health insurers generate most of their revenue from Medicare Advantage, while others are more heavily focused on Medicaid or commercial markets.
- Medical care ratio (MCR): Also sometimes referred to as the benefit expense ratio, medical cost ratio, medical loss ratio, or medical benefit ratio, this metric measures medical costs as a percentage of premium revenue. The higher the MCR, the less profitable the health insurer.
- Diversification beyond health insurance: It's increasingly common for health insurers to diversify into other businesses (and for other businesses to diversify into health insurance). That's been the case with several of the companies on our list, especially UnitedHealth Group and CVS Health. Pay close attention to health insurers' other areas of focus since they can significantly affect a company's growth prospects and associated risks.
Risks for health insurance companies
Like all businesses, healthcare companies face risks, including economic downturns and rising competition. However, health insurance companies also have a few unique risks, including those related to:
- Regulatory changes: The health insurance industry is highly regulated at the federal and state levels. The potential for major regulatory changes that cause challenges for health insurers is an ongoing risk. For example, if the U.S. implemented a single-payer health plan in the future, health insurers would likely see many of their business opportunities vanish. It's also possible that presidential administrations could curtail federal funding for Medicare and Medicaid.
- Reimbursement pressure: Even without major regulatory changes, health insurers continually face potential pressures related to reimbursement rates that can significantly alter their profits. Companies must secure approvals for insurance premiums from state regulators, who can be reluctant to pass on higher costs to their states' residents. Medicare and Medicaid programs also set reimbursement rates that can hurt health insurers' bottom lines.
- Unforeseen medical costs: Health insurers set their monthly or annual rates based on expected medical costs, and there's always the possibility that medical costs could be much higher than anticipated. For example, some major health insurers noted modest increases in costs due to COVID-19.
Benefits of health insurance companies
The benefits of health insurance companies from an investing standpoint include:
- They typically generate relatively steady revenue and cash flow.
- Barriers to entry for new competitors are high.
- Aging demographic trends create growth opportunities for health insurers that offer Medicare Advantage plans.
- Health insurance companies often pay attractive dividends.
