Nikkei 225 rises 2.87% as AI stocks rebound, SoftBank up about 14%

What happened. Japan's Nikkei 225 closed at 60,459.58 on Tuesday, November 10. That is 1,684.08 points, or 2.87%, above Monday's close of 58,775.50. The index traded between 59,268.43 and 60,743.97. At 12:35 p.m. Tokyo time it eased to 60,180.46, after the morning session ended at 60,475.78, but it finished close to the morning level.

Where it came from. On Friday the index fell 5.96% to 57,434.77, below 60,000 for the first time since May. The Japan Times linked that to heavy losses in US tech shares and to concern that the Democrats' win in the US midterm elections could bring tighter AI rules and slower data centre building. The Nasdaq composite had dropped 5.5% and the Philadelphia Semiconductor Index 12.3%. On Monday the Nikkei rose 2.33%. Wall Street also rallied, with the S&P 500 up 2.3%, the Dow up 2.2% and the Nasdaq up 2.7%, while oil prices fell.

SoftBank. Shares of the investor in AI companies closed at ¥3,872, against ¥3,400 a day earlier, about 14% higher. They had fallen about 10% on Friday. AP reported that the jump came ahead of its earnings release later in the day. Reuters then reported a net loss of ¥1.1 trillion ($7 billion) for July-September, against a profit of ¥2.5 trillion a year earlier. SoftBank has spent $64.6 billion on a 13% stake in OpenAI, and its shares have almost halved since the start of June.

Not everything went up. Nvidia fell about 4% on Monday while its board is looking into reports about its CEO. Reuters, as quoted by The Economic Times, said investors saw this as a company matter, not a threat to AI as a whole. Tokyo Electron and Advantest, which make chip equipment, rose in Tuesday trading.

What it does not mean. The index is still below its November 5 close of 61,077.90 and well under its June record of 72,831.73. The Nikkei 225 is a price-weighted index of 225 stocks on the Prime market of the Tokyo Stock Exchange, according to its provider. In three sessions it fell 5.96%, then rose 2.33% and 2.87%. This is a look at what happened, not a forecast.

What to watch. US consumer prices for October are due later today. Economists polled by Dow Jones expect headline prices up 0.3% and core prices up 0.2% from September, according to CNBC. In Tokyo, Wednesday is the first full session after SoftBank's loss. The open question is whether buyers keep coming back to AI stocks or last week's data centre worry returns.
