When investors are paying such high price tags for a stock, expectations are high, and any kind of miss can result in a steep correction. Lilly is by no means in bad shape, but because the stock's price has become so inflated in recent years, so have expectations.

All told, Lilly stock still gained 33% in 2024, outperforming the S&P 500 and Nasdaq Composite. Unfortunately, Lilly investors haven't had much to celebrate so far in 2025. On Jan. 14, shares of Lilly dropped by as much as 8% and ended the day down around 6%. Year-to-date, share prices are down about 1.4%.
