How to Trade Eli Lilly (LLY)

Colonel Eli Lilly, a 38-year-old pharmaceutical chemist, founded the company in 1876. Frustrated by the poorly prepared medicines of the time, he committed to manufacturing high-quality prescription drugs. His early innovations included gelatin-coating for pills and tablets, which became an industry standard.

In collaboration with the University of Toronto, Eli Lilly became the first company to commercially manufacture and distribute insulin (Iletin) for the treatment of diabetes. This breakthrough saved millions of lives and established Lilly as a global leader in endocrine health.

The FDA approved Prozac (fluoxetine), the first SSRI antidepressant. It became a cultural phenomenon and one of the best-selling drugs in history, fundamentally changing how mental health was treated and launching Lilly into a new era of blockbuster drug profitability.

The FDA approved tirzepatide for chronic weight management (marketed as Zepbound). Combined with its success in diabetes (Mounjaro), Lilly saw an unprecedented surge in demand. The drug's superior weight-loss efficacy compared to older generations made it a primary growth driver.

Driven by the obesity drug explosion, Eli Lilly's market cap surpassed $800 billion, briefly overtaking Tesla and becoming the most valuable healthcare company globally. It joined the elite club of the top 10 largest US companies, fueled by clinical success in Alzheimer's (Donanemab) and weight loss.
