Why did Pfizer (PFE) stock fall 2% today?

The decline of Pfizer's (PFE) stock by 2% today can be attributed to a combination of factors: 1. **Earnings Report**: Pfizer is set to release its earnings report today, which is likely causing volatility in the stock as investors adjust their positions. 2. **COVID-related Revenues Decline**: The decrease in Pfizer's stock price reflects the impact of declining COVID-related revenues. As the pandemic wanes, the demand for Pfizer's COVID-19 vaccine and treatments decreases, leading to a reduction in revenue. 3. **Patent Expirations**: The expiration of patents on some of Pfizer's top-selling drugs, such as Eliquis and Prevnar 13, next year, is a concern for investors. Loss of exclusivity can lead to a significant drop in sales. In summary, the stock price decline is likely a result of a combination of factors including earnings report, COVID-related revenues decline and patent expirations. |code|Ticker|Name|Date|Post-Market Percentage Change|Percentage Change|Pre-Market Percentage Change|market_code| |---|---|---|---|---|---|---|---| |PFE|PFE.N|Pfizer|20250730|0.1256|-2.0165|0.1695|169|
