According to Allied Market Research, the size of the global healthcare insurance industry stood at $1.98 trillion at the end of 2020. The COVID-19 pandemic has resulted in an increased demand for health insurance around the world. The size of the industry is expected to compound annually at an average rate of 9.7% to reach $4.15 trillion by 2028. People consider health insurance services as an integral tool to share medical costs during accidents, illnesses, and injuries. The impact of the delay in routine healthcare services during the COVID-19 pandemic played favorably for health insurance companies. However, this effect was also offset by the increase in demand for COVID-19-related testing and treatment claims.
The Protection Gap: Addressing Economic Losses in Health Insurance and Beyond
Experts believe that health insurance companies that can innovate and transform their offerings according to customers’ demands will be able to grow during these uncertain times. The uncertainty related to geopolitical and macroeconomic outlook has made business stability the top priority amongst health insurance companies such as Centene Corporation (NYSE:CNC), UnitedHealth Group Incorporated (NYSE:UNH), and Elevance Health, Inc. (NYSE:ELV).
In addition, the protection gap is growing with every passing day as the insurance related to natural disasters, cyber attacks, and health, only partially covers the actual economic losses related to these events. For instance, in 2019, more than 400 natural disaster events resulted in an economic loss of $232 billion, but only $71 billion of the loss was insured. This gap is expected to increase as the global population and life expectancy rise. These factors would provide the health insurance industry with a bigger market to target.
According to the Swiss Re Institute, the insurance industry could increase its bottom line by $60 – $80 billion annually if it works on reducing the insurance protection gaps. As of 2021, the global insurance protection gap stood at $1.4 trillion, while the global health protection gap was estimated at $737 billion. Experts believe the higher government spending on healthcare during the COVID-19 pandemic helped reduce the health protection gap; however, it is expected to increase again as the pandemic has eased and governments around the world are shifting their focus towards other activities. Experts also highlight the low level of insurance literacy as a major challenge in gaining widespread market penetration. According to research conducted by French insurer SCOR, a significant number of people do not purchase insurance because they cannot comprehend the terms and conditions. The study comprised 12,000 consumers from around the world. Governments, regulators, insurance companies, and employers must come together to address the challenges to boost the adoption of health insurance.

10. CVS Health Corporation (NYSE:CVS) [ Owner of Aetna]
TTM Total Revenue (Aetna): $82.2 billion
CVS Health Corporation (NYSE:CVS) is a Woonsocket, Rhode Island-based healthcare company that is also a provider of health insurance services.
The company acquired Aetna in 2018 to expand its presence in the health insurance segment. Based on 2021 total health plan enrollments, CVS Health Corporation secured the sixth position with 2,574,348 enrollments. In a note issued to investors on February 9, Brian Tanquilut at Jefferies increased the target price for CVS Health Corporation from $130 to $143 and maintained a Buy rating on the stock following the strong Q4 2022 results. The company also disclosed that it intends to acquire Chicago, Illinois-based healthcare company Oak Street Health, Inc. (NYSE:OSH) for a sum of $10.6 billion. The analyst anticipates the earnings from Oak Street to contribute towards the company’s bottom-line growth after 2024.
Vltava Fund shared its outlook on CVS Health Corporation in its Q3 2022 investor letter. Here’s what the firm said:
“CVS is a leader in the provision of healthcare services in the USA. It has three main businesses: an enormous network of pharmacies, a health insurance company, and “prescription benefit management”, which is a kind of intermediary between insurance companies and pharmacies. This is the result of large acquisitions over the past 15 years – most notably of Caremark (2007) and Aetna (2018). The markets had deemed its acquisition of health insurer Aetna too expensive (and we agree), so CVS stock then fell into disfavour for a few years.
We took advantage of this in the summer of 2020 and brought the stock into our portfolio at a time when its price was pressed down still further by the coronavirus pandemic. CVS is a giant. It has revenues of USD 300 billion, making it one of the largest companies in the world. It is a relatively stable and highly profitable company with strong free cash flow. Over the past few years, CVS has focused primarily on reducing debt.
This is already much lower than it had been after the Aetna acquisition, and most of the cash is now likely to go to shareholders through share buybacks or be used for smaller acquisitions to grow the company further. CVS trades at about 11 times annual earnings, which is a very appealing valuation given the expected future growth in profitability and overall modest cyclicality in its business.”

The analyst highlighted the company’s decision to exit the Employer Group Commercial Medical Products business company. The business segment included the Federal Employee health benefit plans and rewards programs that are fully insured and self-funded.
Here’s what Renaissance Investment Management said about Humana Inc. in its Q3 2022 investor letter:
“In September, We added a new position in the Health Care sector with Humana Inc. (NYSE:HUM), one of the largest managed care providers in the U.S. with a focus on medical insurance for the Medicare Advantage market. We believe Humana is poised to see a reacceleration in Medicare Advantage membership growth after making large investments in its program benefits earlier this year.
