US stock markets: Wall Street is in the red – bond yields are falling

Dusseldorf. The fear of a costly arms race in artificial intelligence is also weighing on the US stock exchanges at the end of the current trading week. The major US indices on Wall Street were also largely in the red on Friday.

The Dow Jones of standard values ​​is down almost 1.5 percent at 52,096 points.

The more broadly diversified S&P 500 lost 0.6 percent and reached 7,615 points.

The Nasdaq technology exchange is trading 0.4 percent lower at 25,934 points.

The Nasdaq 100, which tracks the 100 largest non-financial companies with the highest market capitalization, opened at 25,934 points, hardly changed.

Technology stocks in particular have recently come under pressure and, with a loss of 2.6 percent, gave the Nasdaq stock exchange its biggest daily loss since the beginning of June.

The Nasdaq 100 volatility index is currently at 29, data from LSEG shows. The average over the past twelve months is 24, according to Thomas Altmann, portfolio manager at QC Markets. The index is therefore above average, but the market is far from panic: in April 2025 the barometer reached almost 40 points.

Investors are currently not worried about current profits, but about future ones. Several large technology companies have presented good quarterly figures, but also announced that they will invest more money in AI. Investors worry that these expenses will squeeze subsequent profits and won't pay off quickly. At the beginning of the week, the strong numbers had supported the US stock markets. Then the costs came into focus.
