On September 14, the Nikkei 225 index closed at 63,492.99 points, marking a decrease of 518.35 points, or 0.81%, compared to the previous Friday. During the trading session, the index briefly dipped below the 63,000-point threshold, a level not seen since August 4. Stocks related to AI and semiconductors generally experienced a downturn, influenced by the announcement that U.S.-based OpenAI would delay its public offering until next year (or news of OpenAI not going public this year, depending on the most up-to-date information) and widespread market anxieties about a potential deceleration in AI advancement. Concurrently, the elevated prices of U.S. crude oil futures further amplified the selling pressure. Nevertheless, after a lower opening in the morning, short-term funds began to provide buying support for Nikkei 225 index futures, which gradually helped the index to swiftly regain stability and reduce its losses.
