Nikkei Slips as Chip Rebound Fades Before U.S. CPI

Tokyo stocks fell on October 14 as a brief rebound in semiconductor and AI-related shares fizzled before U.S. inflation data was released. The Nikkei 225 closed 33 points lower at 67,744, while the broader TOPIX slipped 13.89 points to 4,096.78. Prime Market activity was robust, with a volume of 2.18982 billion shares and a trading value of 7.4507 trillion yen.

The Nikkei opened higher after a four-day decline, but the early gains evaporated as the session progressed. The rebound was driven by high-priced technology and AI stocks, including Advantest, SoftBank Group, and Sony Group. However, the rally lost steam in the afternoon, with the Nikkei ending down for the fifth consecutive day.

The market's weakness was evident in the performance of banks, securities, and precision instrument shares. The broader market also struggled, with 57.4% of stocks falling and only 38.9% rising. The main overseas catalyst was the upcoming U.S. Consumer Price Index (CPI) report, which investors were watching closely for clues on potential Federal Reserve rate action.

A stronger-than-expected CPI would likely support the dollar, while a weaker reading could benefit Japanese exporters by strengthening the yen. Despite the mixed signals, the bond market remained relatively stable, with the 10-year JGB yield unchanged at around 3.000%. The Bank of Japan's September rate hike to 1.25% continues to shape market expectations, with investors awaiting further guidance from the central bank.

The AI and semiconductor sectors remained the dominant swing factor, with investors closely monitoring how these stocks would react to the day's events.
