89bio Plunges 27.62% on Weiss Ratings Downgrade

On April 10, 2025, 89bio's stock price plummeted by 27.62% in pre-market trading, marking a significant decline and setting a new one-year low for the company.

89bio's recent stock performance has been influenced by several key factors. Raymond James upgraded the company to a "strong-buy" rating in December 2024, indicating a positive outlook from some analysts. However, Weiss Ratings maintained a "sell (d-)" rating, suggesting caution among other market observers.

These contrasting ratings reflect the mixed sentiment surrounding 89bio, with some analysts optimistic about the company's future prospects while others remain skeptical. The recent downgrade by Weiss Ratings may have contributed to the significant drop in stock price, as investors reacted to the negative rating.
