Berliner Abendpost - Stocks edge down over worries about tech and Nvidia

Bitcoin also briefly fell below the key $90,000 level for the first time in seven months before rising again, as traders increasingly believe the US Federal Reserve will decide against an interest-rate cut next month.

With US markets slumping on opening after a rough day of trading in Europe and a sharp sell-off in Asia, Nvidia itself dropped more than three percent.

"The tech-focused sell-off seen in the US has evidently resulted in global contagion," said Joshua Mahony, chief market analyst at Scope Markets.

Fawad Razaqzada, market analyst with StoneX, pointed out that usually reliable commodities like gold and copper had also been forced downwards.

After this year's record stocks rally, traders have begun to question whether the billions poured into artificial intelligence will ever lead to big returns.

Investors will be looking for clues as to the health of the industry when Nvidia releases its quarterly earnings, expected on Wednesday.

They will also be parsing the US September jobs report on Thursday -- delayed by the government shutdown -- for fresh signs that a rate cut could happen.

Meanwhile, reports from retailers Home Depot, Target and Walmart will also give an insight into consumer sentiment.

Earlier, Tokyo tumbled as Prime Minister Sanae Takaichi prepared to unveil an economic stimulus package.

Yields on 20-year government bonds hit their highest since 1999 as speculation grows that the spending bill will ramp up borrowing.

The yen slipped to around 155.38 per dollar, its weakest since January, as expectations of more interest rate hikes faded.

Razaqzada said of all the worries hitting the markets, Japan was perhaps the biggest.

"Markets now worry that the government is mishandling the economy, demanding higher returns to compensate for what they perceive as rising risk in holding Japanese debt," he said.
