Latitude Investment Management, an investment management firm, released its fourth-quarter 2025 investor letter. A copy of the letter can be **downloaded here**. The letter emphasizes a long-term, fundamentals-driven investment philosophy, arguing that while stock prices can be volatile in the short run, they ultimately follow underlying earnings growth—illustrated through the “dog and owner” analogy. The portfolio delivered strong results in 2025, with earnings growing over 15% and returns of 21%, largely driven by consistent fundamental growth rather than valuation changes. The manager highlights a diversified portfolio of high-quality, cash-generative companies with solid market positions, low investment needs, and attractive shareholder returns through dividends and buybacks. The letter notes selective portfolio shifts toward more defensive, attractively valued names while maintaining double-digit growth potential. Looking ahead, the outlook remains positive, with expectations for continued earnings growth, improving opportunities from market dispersion, and attractive valuations providing a margin of safety despite limited exposure to crowded themes like AI.

In its fourth-quarter 2025 investor letter, Latitude Investment Management highlighted stocks like UnitedHealth Group (NYSE:UNH). UnitedHealth Group (NYSE:UNH) is a diversified healthcare company providing insurance and healthcare services through its UnitedHealthcare and Optum segments. The one-month return of UnitedHealth Group (NYSE:UNH) was 21.75% while its shares traded between $234.60 and $405.15 over the last 52 weeks. On May 15, 2026, UnitedHealth Group (NYSE:UNH) stock closed at approximately $393.85 per share, with a market capitalization of about $357.67 billion.
Latitude Investment Management stated the following regarding UnitedHealth Group (NYSE:UNH) in its Q4 2025 investor letter:
was one of two stocks in our portfolio that delivered a negative return for the year, down 33%. United Health is the largest MCO, with a membership of 51 million people, overseeing $400bn of healthcare expense reimbursement across US commercial health insurance plans, as well as government programmes (Medicare and Medicaid). There were two primary issues in 2025:"UnitedHealth Group (NYSE:UNH)First, medical cost trends were significantly higher than expectations at the outset of the year (+7.5% compared to the +5% they budgeted for). 7 To put it into figures, United Health generated operating profits of $32bn in 2024, an 8.3% margin. A -2.5% deviation on costs on a total of $400bn of spend is a $10bn impact on the business, and the main reason why the earnings shortfall this year was quite so dramatic.
Second, they recently attracted a large number of new members, from weaker peers, who exhibited worse health attributes than expected. It’s our view that this happened due to United Health’s superior coverage and service, making a greater level of care available with greater ease..." (Click here to read the full text)
Four leading AI models discuss this article
"Sustained medical cost pressures and adverse selection risks make near-term earnings recovery for UNH less certain than the letter implies."
UNH's 33% drop stems from a 2.5% medical cost overrun on $400bn in spend, equating to a roughly $10bn earnings hit against 2024's $32bn operating profit at an 8.3% margin. The adverse member mix from weaker peers introduces classic adverse selection, where higher utilization could persist if premium hikes lag or regulatory scrutiny on Medicare Advantage intensifies. This matters because UNH's scale across 51 million members gives it pricing power but also exposes it to systemic cost inflation in commercial and government books. Watch whether 2026 bids reflect these trends or if margins compress further.
The new members may ultimately improve scale efficiencies and data advantages for Optum, allowing faster repricing and utilization controls that turn the mix shift into a net positive by 2027.
"UNH's 2025 miss wasn't just bad timing on medical inflation—it revealed execution risk in M&A and member selection that may persist, and the stock's recovery to near-highs prices in a return to normalcy that isn't guaranteed."
UNH's 33% decline is arithmetically explainable but masks a deeper structural problem. The $10bn cost miss (2.5% on $400bn spend) is real, but the second issue—adverse member mix from acquisitions—suggests UNH overpaid for or misunderstood the health profiles it was buying. This isn't a one-year weather event; it signals either poor underwriting discipline or that UNH's 'superior coverage' pricing power has limits. At $393.85 (May 2026), the stock trades near 52-week highs despite 2025 losses, implying the market has already priced recovery. The risk: if 2026 guidance assumes normalization of medical trends AND successful integration of sicker members, and either fails, downside is substantial. The letter's tone—'our view' on why members switched—reads defensive.
UNH's scale (51M members, $400bn spend) and market position are durable. A 2.5% cost miss in one year, while painful, is recoverable through pricing discipline and operational tightening in 2026-27; MCOs have done this before. If medical trends revert to +5% and member mix stabilizes, earnings could re-rate sharply from depressed 2025 base.
"UnitedHealth’s recent membership growth has acted as a toxic asset, introducing adverse selection risks that will continue to pressure margins until actuarial data catches up to the new member mix."
The 33% drawdown in UNH highlights a classic 'adverse selection' trap. While Latitude frames the earnings miss as a temporary mismatch between medical cost trends (7.5% actual vs. 5% budgeted) and premium pricing, the structural risk is more severe. UNH’s aggressive expansion into lower-tier demographics has effectively diluted its risk pool. With a $400bn cost base, even a 250-basis-point margin compression is catastrophic for EPS growth. UNH is essentially paying the price for its own scale; as they absorb members from failing peers, they are importing systemic volatility into their actuarial models. Until we see a sustained normalization in medical loss ratios (MLR) and a repricing of government contracts, the valuation floor remains shaky.
The bear case ignores that UNH’s scale allows it to leverage its Optum data advantage to price risk more accurately than any competitor; once the current cohort of new members is fully underwritten, the earnings rebound could be explosive.
"UNH's durable moat and pricing power suggest margins should recover once medical-cost inflation normalizes and the new-member mix stabilizes."
UNH's 2025 shock came from higher medical cost inflation (+7.5% vs budget +5%) and a stronger-than-expected influx of new, higher-risk members. The market overreacted to a one-year miss; UNH still benefits from dominant scale, diversified revenue (UnitedHealthcare and Optum), and pricing power that should help absorb inflation. The article glosses over the likelihood that cost inflation normalizes and that the new member mix stabilizes, allowing margins to recover. Missing risks: MA regulatory margins, competitive pricing pressure, and how quickly added members translate into higher claims versus offsets. (Speculative) If medical-cost inflation reverts toward the plan, earnings power reasserts.
Bearish counterpoint: The weakness may be durable; MA margins are under regulatory pricing pressure, and higher-risk member mix could worsen claims experience for years, leaving less room for a quick margin rebound.
"Persistent adverse selection and regulatory risks could prolong margin pressure beyond 2025 despite UNH's scale."
ChatGPT underestimates the persistence of adverse selection risks. While scale provides some buffer, the influx of higher-risk members from weaker peers could elevate MLRs beyond 2025 if competitors' exits continue. This connects directly to Grok's point on 2026 bids: if those bids fail to fully price in elevated utilization, margin compression may extend into 2027 rather than normalize quickly. Regulatory pressure on Medicare Advantage could further limit repricing flexibility, an angle not yet addressed.
"Regulatory repricing lag creates a 9-month earnings trough independent of whether medical trends normalize."
Grok flags regulatory repricing constraints—valid. But nobody's quantified the actual 2026 bid submission timeline or CMS pricing guardrails. If UNH can't reprice Medicare Advantage until Oct 2026 bids, they're locked into 2025 cost experience for 9+ months. That's a material cash-flow and earnings timing risk that compounds the adverse selection story. ChatGPT's 'normalization' thesis assumes pricing flexibility UNH may not have.
"UNH’s integrated model creates a double-exposure risk where elevated utilization simultaneously destroys margins in both the insurance and provider segments."
Claude is right about the CMS bid cycle, but the panel is missing the Optum-side tail risk. If medical cost inflation persists, Optum’s 'value-based care' contracts—which rely on capitated payments—become massive liabilities rather than assets. UNH isn't just an insurer here; they are the provider. If utilization stays elevated, they lose on both sides of the ledger. This isn't just an adverse selection problem; it is a fundamental breakdown of their integrated model's margin protection.
"CMS pricing delays could cap 2026 margin rebound, creating meaningful downside risk even if commercial pricing improves."
Claude’s CMS timing point is real, but the bigger flaw is assuming linear normalization. The 9–12 month pricing lock means 2026 margin upside is not just delayed—it could be structurally limited until late 2026 or 2027 if higher-cost cohorts persist. If government contracts don’t reprice quickly, Optum’s capitated models could remain cash-flow headwinds even as commercial pricing improves. That implies a shoestring path to margin recovery and a tighter risk of downside in 2026.
The panel consensus is bearish, with the key concern being UNH's exposure to adverse selection risks due to higher-risk members from weaker peers, which could lead to sustained margin compression and earnings misses. The panel also flags regulatory pricing constraints and Optum's capitated payment model as significant risks.
