In the first half of January, the Nikkei Stock Average experiencing a decline on January 4th, the first trading day of the year, largely due to the immediate market reaction to the Noto Peninsula earthquake on New Year's Day. However, this initial downturn was quickly overturned by broader economic factors. As speculation grew around the Bank of Japan potentially postponing its monetary easing, coupled with expectations of a delay in U.S. interest rate cuts due to strong economic indicators of the United States, the yen depreciated to the \145/$ level. This depreciation, viewed positively by the market, spurred a bullish sentiment among investors, particularly foreign investors. Consequently, the Nikkei 225 enjoyed a six-day rally from January 5th to the 15th, peaking at 35,901. Despite a period of profit-taking selling that reflected caution over the high market prices, the index found new strength by the late in the month. Fueled by the rise in U.S. stocks, the Nikkei 225 reached its highest level in nearly 34 years on January 22nd, at 36,546. Although the month closed with the index slightly off this peak at 36,286, due to a cautious focus on domestic and international earnings announcements, the overall trend remained positive. Foreign investors and business corporations were net buyers,　while　 individual investors and trust banks were net sellers.
