author:US stockS -
On August 21, 2025, the US stock market experienced a tumultuous day that left investors on edge. The Dow Jones Industrial Average (DJIA) closed at 36,475.12, a drop of 312.45 points or 0.85%. The S&P 500 index finished the day at 4,695.78, down 39.45 points or 0.84%, while the NASDAQ Composite closed at 15,677.67, a loss of 147.78 points or 0.94%.
Market Highlights:
- Technology Stocks Suffered the Most: Technology stocks, which have been a major driver of the market's growth, took a significant hit. The NASDAQ 100 index, which tracks the largest non-financial companies listed on the NASDAQ, closed down 1.6%. Key tech stocks like Apple, Microsoft, and Amazon saw their shares fall by 2% to 3%.
- Energy Stocks Led the Decline: The energy sector was among the worst performers, with the Energy Select Sector SPDR ETF falling 2.5%. This was largely due to concerns about the global oil supply, which were exacerbated by tensions in the Middle East.
- Retail Stocks Were Mixed: Retail stocks had a mixed performance, with some of the biggest winners being discount retailers like Walmart and Dollar General, while department stores like Macy's and J.C. Penney saw their shares decline.

Key Factors Influencing the Market:
- Economic Data: The market was affected by a series of economic data releases that suggested a slowdown in economic growth. The Consumer Price Index (CPI) for July showed a 0.4% increase, while the unemployment rate remained at 3.7%.
- Inflation Concerns: Concerns about rising inflation continued to weigh on the market. The CPI report showed that inflation remains above the Federal Reserve's target of 2%.
- Geopolitical Tensions: The escalating tensions in the Middle East also contributed to the market's volatility. The attack on an oil tanker in the Gulf of Oman raised fears of a potential conflict that could disrupt global oil supplies.
Case Study:
One notable case study was the performance of Tesla, Inc. (TSLA). Despite the overall market downturn, Tesla's shares actually rose by 1.2%. This can be attributed to the company's strong second-quarter earnings report, which showed robust sales and profit growth. The company's success in expanding its production capacity and securing orders for its new Model Y helped offset the broader market's concerns.
Conclusion:
The August 21, 2025, US stock market closing summary paints a picture of a market that remains highly volatile and unpredictable. While technology stocks and energy stocks were among the biggest decliners, the resilience of certain companies like Tesla shows that there are still opportunities for investors to find value in the current market environment. As always, it is important for investors to stay informed and remain cautious when navigating the complexities of the stock market.
