The S&P 500 hit a new all-time high on Thursday, August 13, as investors welcomed positive data on producer prices, the decline in oil prices, and a new rise in technology stocks.
The main stock market index surpassed the 7.800 point mark for the first time intra-session, just seven sessions after reaching 7.700 points. This move confirmed the momentum that the US market has developed, but also highlighted its heavy dependence on the technology sector.
The Nasdaq rose, supported by semiconductor and artificial intelligence companies. In contrast, the Dow Jones experienced small losses, as a sharp decline in Cisco Systems disproportionately affected the index.
The different paths of the three major indices show that not all stocks participated in the rise in the same way. Technology and semiconductors were at the center of the markets, while some traditional industrial companies and consumer products companies came under pressure.
The main impetus came from new data on wholesale inflation. The Producer Price Index remained unchanged in July on a monthly basis, while economists had expected an increase.
On a year-over-year basis, producer prices rose 4,7%, down from 5,5% in June. While the rate remains high, the slowdown temporarily reassured investors who had been worried that persistent price increases would force the Federal Reserve to raise interest rates again.
Markets are particularly sensitive to the Federal Reserve's decisions. Higher interest rates increase the cost of borrowing for businesses and households and tend to pressure stock valuations. This is especially true for technology companies, whose stock market value is based on expectations of future earnings.
After the new data was released, investors scaled back their expectations for a rate hike at the Federal Reserve's September meeting. The likelihood of rates remaining unchanged increased, causing US Treasury yields to fall.
The 10-year Treasury yield fell to near 4,64%. The decline in yields has particularly helped real estate and technology companies, as it lowers financing costs and makes stocks more attractive compared to bonds.
The decline in oil prices also played a significant role. Brent and US crude moved lower as US inventories rose sharply and international organizations reduced their forecasts for global demand.
The fall in oil has a double meaning. On the one hand, lower prices limit energy costs for businesses and consumers and reduce the risk of a new wave of inflation. On the other hand, concerns about lower global demand may be a warning of a slowdown in the international economy.
In the technology sector, Sandisk and Micron shares posted strong gains, boosting the entire semiconductor industry. Major companies such as Microsoft, Nvidia and Apple also performed positively.
Optimism around artificial intelligence and data center investments continues to be a key driver of the market. Investors believe that large spending on technology infrastructure will create new revenue streams for companies that supply processors, storage systems and software.
Not all corporate news was positive, however. Cisco Systems fell about 9% as investors expressed concerns about its profit margins despite strong revenue guidance. Because the Dow Jones is calculated based on share prices rather than the total market value of companies, Cisco's decline had a noticeable impact on the index.
Tapestry, the parent company of Coach and Kate Spade, also fell sharply after reporting earnings that disappointed Wall Street, a reminder that even in a bullish session, investors are still scrutinizing the prospects of every company.
The S&P 500's rise above 7.800 is a significant milestone for the US market. However, it does not mean that the risks have disappeared.
Inflation remains above the Federal Reserve's target, geopolitical tensions continue to weigh on energy, and the labor market is showing low layoffs but limited hiring momentum. At the same time, high valuations of technology companies raise questions about whether they can continue to grow at the same pace.
For now, Wall Street is choosing to focus on the positives: wholesale inflation has fallen, oil has become cheaper, and the Federal Reserve appears to have more room to wait before deciding its next move.
Whether the rally will last will depend on the next data on inflation, employment and corporate earnings. The market is at historic highs, but it is still moving between optimism about technology and concern about the cost of money and the global economy.
