Why did stock drop in after hours and will it go up again

The SPDR S&P 500 ETF Trust (SPY) experienced a slight drop of 0.04% in the post-market session on July 21, 2025. This decline can be attributed to several factors:

1. **Trump's Tariff Threats**: The EU is preparing a $24.5 billion tariff package in response to Trump's threat of a 30% import tax on Mexico and Europe. This geopolitical tension and potential trade disruptions can lead to investor uncertainty and sell-offs.
2. **State Street's Rising Costs**: State Street Corporation reported a 11% increase in total expenses, primarily driven by workforce rationalization and Alpha-related client rescoping. This could indicate operational challenges and affect investor confidence.

However, there are positive factors that could lead to an upward movement in SPY:

1. **Retail Sales and Jobless Claims**: Retail sales and jobless claims data have been upbeat, which could signal a strong consumer sector and potentially lead to increased investor confidence.
2. **PepsiCo's Strong Performance**: PepsiCo reported better-than-expected second-quarter earnings and raised its full-year 2025 adjusted EPS guidance, indicating a strong business performance that could positively impact investor sentiment.

In conclusion, while there are potential headwinds, the positive economic data and strong corporate performance could lead to a rebound in SPY. Investors should monitor these factors closely and consider their overall market strategy.
