AstraZeneca's stock has surged by 137% over the last 120 days, attracting attention from analysts and investors, including Jim Cramer. The company's oncology segment, which has generated $25.6 billion and boasts 16 blockbuster drugs, is driving optimism for future growth. However, AstraZeneca is under scrutiny due to potential UK policy headwinds and an ongoing investigation in China, leading Cramer to advise caution despite the company's ambitious plans to raise revenue to $80 billion by 2030.
