Economic data shows services sector growth slowing

The latest service industry data shows slowing growth. According to the Institute for Supply Management, the services PMI fell to 50.1 in July from 50.8 in June, showing signs of weak economic growth. This data has exacerbated market concerns about the economic outlook.

Breaking company news affects stock prices

Axon Enterprise's share price surged due to earnings that exceeded market expectations and upward guidance. DuPont also raised its full-year guidance and reported better-than-expected results, which led to a rise in its share price. Palantir Technologies shares rose about 5%, benefiting from demand for artificial intelligence products and more government contracts.

Bond yields and other market developments

The yield on the 10-year U.S. Treasury note did not change much, indicating that the market is waiting to see future interest rate trends. In other markets, oil prices fell and gold prices rose. The dollar rose against the yen, but fell against the euro and pound. The prices of major cryptocurrencies fell, indicating increased risk aversion in the market.
