As of Q4'25, the latest PEG Ratio (5yr expected) for UNH stands at -4.59, reflecting a notable decline from the previous quarter's value of -1.07. This negative PEG ratio suggests that the company's expected earnings growth is not keeping pace with its valuation, which may be a point of concern for investors. Over the period from Q1'23 to Q4'25, the PEG ratio has demonstrated significant volatility, fluctuating between positive and negative values. Notable inflection points include sharp drops in Q2'23 (-9.45) and Q4'25 (-4.59), as well as brief recoveries to positive territory in Q3'23 (2.80) and Q1'25 (0.94). This erratic pattern indicates an unstable relationship between UNH's growth expectations and its price-to-earnings ratio over the past two years.
