The essentials
  • The DAX closed up 0.07% at 25,629 points on Friday.
  • Infineon led the DAX with a 6% rise, driven by AI and chip sector enthusiasm.
  • Amazon plans to invest $220 billion in AI infrastructure this year.

AI enthusiasm lifts tech shares

On Friday, the German stock market saw a slight gain, with the DAX rising by 0.07 percent. Specifically, technology stocks rebounded, with chipmakers and companies tied to artificial intelligence drawing attention. A surge of positive results from US firms, particularly Microsoft and Amazon, provided a temporary boost to European markets. However, as the weekend approached, many investors remained cautious.

The DAX briefly approached its record high set in early July but could not maintain the momentum. Still, the index managed a 2.1 percent weekly increase, largely due to the ongoing performance of companies in the tech sector. Timo Emden, a market analyst from Emden Research, pointed out that the stream of strong quarterly reports is at least temporarily overshadowing concerns about geopolitical issues and economic risks.

Chipmakers and AI hopefuls rise

Infineon topped the DAX with an interim price increase of around 6 percent. Chip manufacturers and AI-related companies were in high demand, showing a clear shift in investor confidence. Other firms in the semiconductor space also made gains in the MDAX. Aixtron, Süss Microtec, and Siltronic emerged as top performers. Siltronic, in particular, saw its shares rise following positive analyst opinions after the company's earnings were released the day before.

Jochen Stanzl, the chief market analyst at Consorsbank, suggested that investors are becoming hopeful that AI stocks may now reflect a more balanced level of risk. However, the high valuations and rising costs of investments in the AI sector have made many investors tread carefully.

Amazon and Microsoft drive tech optimism

Amazon added a dose of optimism by announcing plans to invest $220 billion in expanding its AI infrastructure this year. The company's AWS cloud division has gained traction, especially as demand for computing power rises. The division reported strong sales that exceeded analysts' expectations. Microsoft also delivered impressive results, with its cloud business and AI outlook driving a sharp rise in its shares on Thursday. Investors viewed these results as a signal of continued strength for the tech sector.

Serge Nussbaumer, a capital market expert from Maverix, emphasized that artificial intelligence will remain a crucial long-term growth factor. However, not all tech stocks followed the upward trend. Apple's shares tumbled after the company issued a disappointing sales forecast. Bottlenecks in key components ahead of the next iPhone launch led to uncertainty. This development widened the gap in performance among major tech companies.

Despite the AI optimism, broader concerns remain. Geopolitical tensions in the Middle East continue to influence energy markets, with traders moving between fear of escalation and short-term relief. Inflation has also remained a pressing issue. In the eurozone, prices for goods and services rose by 2.9 percent in July compared to the previous year, and in Germany, the rate was slightly lower at 2.8 percent.

While some companies benefited from the positive stock market environment, others faced challenges. Schaeffler shares dropped sharply, falling as much as 18 percent at one point. The MDAX-listed automotive and industrial supplier had to revise its medium-term goals due to ongoing difficulties in the automotive industry, particularly in the electric vehicle segment. Hensoldt also experienced a decline, despite a significant increase in its order intake over the first half of the year. Analysts highlighted that the company's shares are already highly valued. David Perry from JPMorgan noted that Hensoldt is the most expensive defense company in his analysis, with potential upside elsewhere. Puma also struggled, as the company's recent restructuring and weaker demand affected its performance.

“A flood of predominantly positive quarterly figures is currently providing tailwind and is at least temporarily overshadowing the geopolitical concerns.”

The resurgence in AI-linked stocks is part of a broader shift toward tech-led growth, even as traditional sectors and global volatility continue to pull at the market's edges.
