Why Buying the UnitedHealth (UNH) Stock Dip is a Bad Idea

UnitedHealth (UNH) has long been viewed as a defensive play in the healthcare space. As the market leader in private healthcare in the U.S., the company has built its reputation on financial consistency, low default risk, and a reliable dividend. That stability has allowed it to trade with a consistently low beta of around 0.5 over the past five years, making it a go-to name for long-term and risk-averse investors.

So when a stock like that drops nearly 50% in less than a month, it’s a strong signal that something fundamental has broken down—and it’s probably not a small deal. In this case, UnitedHealth has been hit by multiple headwinds at the core pillars of the company’s business model: cost predictability, government relations, corporate reputation, and management stability.

Given the scale of these disruptions, this doesn’t seem like the right time to be aggressive and look at tempting valuations. For now, my stance is to hold on to UNH stock.

When a Defensive Giant Trips Over Its Own Feet

It all began on April 17, when UnitedHealth released its Q1 earnings report and stunned the market by slashing its 2025 earnings forecast from $29.50–30.00 per share down to $26.00–26.50 . The main reason was a sharp and unexpected spike in medical costs, particularly in its Medicare Advantage business. The company ended up serving more patients (and more high-acuity cases) than expected, which severely squeezed profit margins. Healthcare service usage reportedly doubled compared to internal projections, triggering a significant margin hit.

What’s harder to pin down is how the company miscalculated so badly. One likely reason is the use of outdated forecasting models, which relied too heavily on past trends that no longer reflect current realities. Another possible issue is the risk profile of newly enrolled patients. Since Medicare Advantage targets older adults, bringing in a higher-than-expected number of sicker, high-cost patients would naturally push expenses much higher.

And there’s little flexibility to recover those costs. Medicare Advantage pricing is highly regulated and locked in, meaning that if the company underestimated how expensive its member base would be, it’s stuck with the consequences, at least in the near term.
