The latest data point for UNH's P/B Ratio in Q1'26 stands at 2.37, reflecting a continued downward trajectory from the previous quarter's 2.85 in Q4'25 and marking one of the lowest valuations in the observed period. Over the timeframe from Q2'23 to Q1'26, the P/B Ratio exhibited an overall declining trend, starting at a high of 5.84 in Q3'23 before steadily eroding to the current level, with notable drops including a sharp 35% plunge from 3.73 in Q1'25 to 2.41 in Q2'25 and a subsequent rebound to 3.48 in Q3'25 followed by further softening. This area chart highlights increasing volatility in mid-2025, potentially signaling market pressures on UNH's book value multiples, though the long-term pattern suggests sustained undervaluation relative to earlier peaks.
