AMPH vs AZN

AMPH exhibits strong deterministic health with a Piotroski F-Score of 7/9, indicating solid operational efficiency and financial stability, though the absence of an Altman Z-Score raises concern about default risk. The stock trades at a discount to its Graham Number ($28.09) and intrinsic value ($14.21), suggesting undervaluation on a defensive basis. However, this is overshadowed by deteriorating fundamentals: negative revenue and earnings growth (YoY -1.8% and -31.0%), declining quarterly earnings, and a significant 36.4% drop in price over the past month. Insider selling activity further undermines confidence, with $0.95M in sales over six months despite no buy activity.

AstraZeneca's deterministic health score is concerning with a Piotroski F-Score of 4/9, indicating marginal financial stability. While profitability metrics like ROE (21.67%) and gross margin (83.26%) are strong, the current price of $92.95 trades significantly above the Graham Number of $45.06, reflecting high growth expectations. Revenue and earnings growth are robust (12% and 78% YoY, respectively), but recent earnings surprises have been volatile, including a -25.9% miss in Q3 2025. Analysts maintain a strong_buy recommendation, though insider selling and weak technical trends (10/100) suggest caution near-term.
