The latest data point for NKE's PEG Ratio, recorded in Q3'26, stands at -1.26, indicating a negative valuation metric that suggests the stock may be overvalued relative to its earnings growth at that period. Over the timeframe from Q4'23 to Q3'26, the PEG Ratio exhibits high volatility with no clear overall trend, oscillating between negative and positive values; it starts at -2.41 in Q4'23, surges to a peak of 2.83 in Q2'24, drops sharply to -1.30 in Q3'24, and continues fluctuating with notable highs of 2.20 in Q2'25 and 2.99 in Q2'26, interspersed with lows around -1.2 to -1.43 in recent negative periods. This pattern highlights periods of perceived undervaluation (positive ratios) alternating with overvaluation (negative ratios), potentially reflecting inconsistent earnings growth or market expectations for the company. The Q1'26 period has no data, which limits continuity in that segment.
