Bio-Techne shares jumped 6.5% to close at $55.64 following investor optimism over potential drug-pricing agreements, despite a 22.2% decline year-to-date. The stock's performance aligns with broader market reactions to new initiatives from the Trump administration aimed at lowering prescription drug costs.
