Japan's benchmark Nikkei 225 index (TVC:NI225) rebounded 1.82% to reach 65,598.63 on October 16, recovering a portion of the steep 4.9% drop recorded in the previous session. The recovery followed a late rally on Wall Street and a decline in U.S. Treasury yields, which helped calm market fears over debt-funded spending in artificial intelligence.

The rebound gained strength as buying expanded beyond heavily weighted technology stocks into industrial and financial sectors, including Toyota and Mitsubishi UFJ. Thursday's severe fall had exposed the benchmark's vulnerability to technology concentration, where key semiconductor suppliers like Advantest and Tokyo Electron make up a substantial share of the index weight. Reassurances from Nvidia leadership regarding partner financing further stabilized regional market sentiment.

Investors continue to monitor whether broader market participation can sustain the recovery or if underlying concerns over debt levels and artificial intelligence profitability will spark renewed volatility. Analysts caution that if stock prices fall alongside declining bond yields, it could signal a broader unwinding of artificial intelligence capital expenditures.

## Questions and answers

### Why did the Nikkei 225 rebound on October 16?

The Nikkei 225 rose as lower U.S. Treasury yields, a late recovery on Wall Street, and reassuring comments from Nvidia regarding AI financing restored investor confidence following a sharp tech sell-off.

### Which stocks led the recovery in Japanese markets?

Rebounding semiconductor stocks like Advantest and Lasertec were joined by broader market gains in non-technology heavyweights, including Toyota and Mitsubishi UFJ.

### What risks still affect the Nikkei index?
