In short
A brief surge in Japanese technology shares has unraveled, showing that market optimism around artificial intelligence remains fragile when borrowing costs and oil prices climb.
The retreat makes choppy trading across global technology shares likely in the coming weeks as corporate earnings arrive.
Whether this cooling turns into a deeper slump is uncertain, resting on upcoming company profits and central bank rate choices.
How it unfolded
Weak US hiring fuels tech share gains
The advance began after the United States government reported soft monthly employment figures. The data suggested the US central bank was less likely to raise interest rates soon, easing financial pressure on high-growth technology companies. American technology shares advanced, lifting sentiment for Japanese computer chip equipment firms before Tokyo markets reopened.
Tokyo shares follow Wall Street higher
Japanese investors bought shares in semiconductor equipment makers when trading resumed on Monday. The benchmark Nikkei 225 climbed more than 1,600 points, while December futures rose 1,440 points. To reassure markets about government borrowing costs, Prime Minister Sanae Takaichi pledged to limit new bond issuance.
Futures climb before an online claim spreads
Japanese shares extended their gains during Tuesday's daytime trading. Stable demand at a government bond auction eased rate worries, helping the Nikkei top 70,000 points for the first time since July. December futures settled up 810 points at 70,900. After the market closed, a viral post claimed futures had jumped over 1,000 points to 70,948, but exchange records showed no such trade.
Investors take profits as world markets slip
Futures touched 71,070 in overnight trade, but buying quickly faded. By Wednesday afternoon, investors locked in recent profits and rotated out of technology shares. Broader market sentiment turned cautious as rising bond yields and oil supply risks weighed on international exchanges.
Energy fears and chip doubts erase market advance
Selling widened over the next two days as tensions involving Iran drove crude oil prices higher and bond yields remained elevated. Softer sales figures from Taiwan Semiconductor Manufacturing Company added to doubts about tech valuations. The Nikkei fell beneath 69,100, erasing the week's gains. Prime Minister Takaichi reiterated that the government would watch the yen and inflation closely.
Where things stand
Official exchange settlements confirm a sharp rally on October 5 and October 6, followed by a steady reversal through October 9. Osaka December Nikkei futures settled at 70,090 on Monday, 70,900 on Tuesday, 70,360 on Wednesday, 69,100 on Thursday and 69,470 on Friday. Tuesday's daily advance was 810 points, while the contract reached an intraday peak of 71,020.
The social media claim of an after-hours price of 70,948 was not verified. Standard Osaka contracts trade in five- or ten-point steps, making that exact figure an invalid trade price. Upcoming quarterly earnings from chipmakers, along with US inflation data, will shape the market's next path.
