On Friday morning, Japan’s benchmark Nikkei stock index fell more than 3 percent as shares linked to artificial intelligence and semiconductors dropped sharply after disappointing earnings from several major U.S. technology companies.
At 10:54 a.m. local time, the 225‑issue Nikkei Stock Average was down 1,867.61 points, or 2.89 percent, from its 62,791.86‑point close on Thursday.
The broader Topix index also fell, slipping 58.54 points, or 1.46 percent, to 3,944.74.
The slide was traced to a wave of selling in AI‑related and semiconductor shares that followed earnings releases in the United States, where several technology giants reported weaker than expected results. Market observers noted that the decline in Nikkei reflected sensitivity to the performance of technology sub‑sectors that dominate the Japanese market.
Although the Nikkei had been making gains earlier in the week, the overnight rally was erased by the power of the earnings reports, which weighed on investor sentiment toward technology stocks.
Analysts said that the losses in the AI and chip segments highlight the volatility that can arise when global earnings reports have a ripple effect on related sectors in overseas markets.
Because the Nikkei is a weighted index that includes many leading tech names, movements in those shares can exert a large influence on the overall index level, a fact that contributed to the sharp decline seen on that day.
The decline was one of the steepest movements for the Nikkei in recent weeks, raising questions about how long any rally in technology stocks will sustain.
Investors will likely keep a close eye on subsequent earnings releases from other technology firms as well as any changes in global interest rates, which can further impact the sensitivity of technology valuations.
The session ended with the index still below the previous close, underscoring the lingering uncertainty around the impact of the recent earnings reports on the broader market.
It remains uncertain how long the pullback in technology‑related stocks will persist, with market participants awaiting additional data on the performance of the sector.
