Bristol Myers Squibb's (BMY) Disproportionate Stock Decline: Assessing Fundamental Resilience and Catalyst-Driven Recovery Potential

With a fortress balance sheet, a revitalized pipeline, and near-term catalysts on the horizon, the company offers an attractive risk-rebalance profile for investors with a medium-term horizon. While challenges like patent expirations remain, BMY's strategic acquisitions and clinical progress provide a clear path to sustainable growth.
