Tech sell-off pressures Asian stocks, eyes on key central bank decisions and mega-cap earnings

What happened

Asian markets opened lower Monday, led by tech-heavy indices as a global pullback in artificial intelligence and semiconductor valuations continued. Japan's Nikkei 225 fell 0.2% to below 62,500, while Hong Kong's Hang Seng rose 0.5% and mainland China's Shanghai Composite lost 0.11%.

Confirmed

Global impact / market context

Falling technology valuations matter because these companies are among the largest in global stock markets. If investors keep questioning whether heavy spending on artificial intelligence will produce enough profit, they may sell shares, and that selling can spread across Asia and into US markets.

Analyst inference

Investors are cautious before a week of central bank decisions and earnings from Amazon, Alphabet, Microsoft and Intel. Bitcoin dropped to around $79,000. Fiscal expansion in China slowed, with public spending up just 1% through September, which may weaken demand across the region.

Analyst inference

What to watch

1. Earnings reports from Amazon, Alphabet, Microsoft and Intel are due, along with Visa and other non-tech firms; results will show if artificial intelligence spending is producing profit. Confirmed
2. Watch whether the Chinese Communist Party's Fifth Plenum offers guidance on fiscal support, since slower public spending could affect company revenue and costs across industries. Proposed
3. Track Bitcoin near $79,000 and bond yield swings, since sharp moves there could signal whether investors are reducing risk across stocks and digital assets. Analyst inference
