Health Insurance Companies: Rhetoric vs. Reality

Executive Summary

The policy proposal of "Medicare for All" calls for nationalizing the U.S. health insurance system. While this is a politically unlikely outcome, the stock prices of the private sector Managed Care insurance companies have suffered as rhetoric heats up. Yet we believe private sector Managed Care provides a combination of lower cost and better outcomes that make it a critical part of rational efforts to reform healthcare insurance. The attractiveness of the private sector alternatives is evidenced by their increasing popularity and growth relative to the comparable public sector programs. Medicare beneficiaries are increasingly electing the private sector Medicare Advantage option to get more benefits at lower cost, and a wide cross section of states are outsourcing their Medicaid programs to private providers. We believe that the role of Managed Care will grow rather than shrink over the next several years, and that this confusion during the election season will prove to be a great buying opportunity.


In managing the GMO Quality Strategy we look to invest in strong companies that will maintain relevance over the long term, but where sentiment is currently negative for what we believe are short-term reasons. We believe the U.S. Managed Care group of health insurers presents such an opportunity today. The cloud over the sector comes from the “Medicare for All” policy proposal, which threatens nationalization of the health insurance industry. The pressure has ramped up with the Democratic presidential political campaign, with an inflection point occurring when candidate Bernie Sanders threw down the gauntlet to private companies when he tweeted in April, “Our message to Steve Nelson and UnitedHealthcare is simple: When we are in the White House your greed is going to end.”1 We believe this threat has been reflected in the stock prices. The S&P 500 index of Managed Care stocks has underperformed the market by as much as 25% at their September trough.

The threat of government disruption of the healthcare system has more than once provided opportunities for long-term investors. We saw this during the early days of the Obama administration and before then in the Bill Clinton era.2 As a general rule of thumb in investing, it has been a fairly safe bet that reality will fall short of political rhetoric. In this particular instance, our conviction is especially high because Managed Care in the U.S. provides superior healthcare outcomes at lower cost. Indeed, we suspect the private system is more likely to grow through expanded membership than it is to shrink through nationalization.

To make this point, we compare the traditional government sponsored Medicare program with the existing private sector alternative known as Medicare Advantage (or, also, Medicare Part C). Traditional Medicare is a Fee for Service program where the government covers certain procedures and services after deductibles and co-pays. As an alternative, eligible participants (primarily senior citizens) have the option to elect to enroll in a private Medicare Advantage plan subsidized by the government. In Medicare Advantage, the government pays the insurer a set amount per member per month (set based on a risk coding of the participant), and the private insurer takes on the risk. The beneficiary may or may not pay an additional premium based on the strength of the benefits. The basic trade-off that enrollees have been increasingly eager to make is to accept some of the restrictions of managed care, for example, being steered to in-network providers, in order to get additional coverage (physical examinations, fitness, eye care, or supplemental drug programs) that are not included in standard Medicare, as well as lower co-pays. Note that because the insurer is paid a fixed amount, it is incented to provide preventative services and adherence programs that reduce the overall cost of care and provide superior outcomes. Further incentives are provided through the government’s star system that can increase the payments to the insurer based on a roster of quality of care and service metrics.
