Investors Trading Trends in Japanese Stock Market: An Analysis for December 2023 and the Full Year　|ニッセイ基礎研究所

In December 2023, the Nikkei Stock Average experienced notable fluctuations, primarily influenced by the monetary policy outlook in Japan and the United States, as well as movements in the foreign exchange market. The month began with a downturn in the Nikkei 225, which fell to 32,775 on the 5th. This decline was largely attributed to a decrease in U.S. interest rates, sparked by growing concerns over the U.S. economic outlook. Concurrently, the yen appreciated to \146/$ level, its strongest position in approximately three months, adding further pressure to the market. Furthermore, on the 7th, the Bank of Japan Governor's comments raised expectations of an early revision of monetary policy, and the Nikkei 225 fell to 32,307 on the 8th. However, the mood in the market shifted following the Bank of Japan's monetary policy meeting on the 19th. The decision to maintain the current policies brought a sense of stability and optimism, propelling the index to a high of 33,675 on the 20th. In the latter half of the month, concerns over the yen's ongoing appreciation restrained the index's upward movement, and it closed at 33,464 at the end of the month. Foreign investors and business corporations were net buyers, while individual investors and trust banks were net sellers.

In reviewing the trading trends of various types of investors in the Japanese stock market throughout 2023, distinct patterns emerge. As illustrated in Chart 5, which spans from January to December 2023, there are clear differences in investment behaviors across investors’ types. Notably, foreign investors and business corporations emerged as the primary net buyers in the market. Foreign investors led the buying trend with a total of 6.29 trillion yen, followed by business corporations with 4.88 trillion yen. Conversely, trust banks and individual investors were the main sellers, offloading 5.41 trillion yen and 3.21 trillion yen, respectively.

Chart6: Foreign Investors Net Buy for 10 consecutive weeks since first week of April.

One of the standout observations is the consistent overbuying by foreign investors for ten consecutive weeks starting from the first week of April. This sustained buying spree was largely driven by several factors: expectations for corporate reforms mandated by the Tokyo Stock Exchange (TSE), a bullish sentiment towards Japanese stocks among prominent U.S. investors, and a favorable financial environment. During this period, the Nikkei Stock Average experienced a significant rise, approximately 4,000 yen. Simultaneously, business corporations actively participated in the market, primarily influenced by corporate share buybacks. In 2023, the amount set aside for share buybacks by listed companies, which are components of the TOPIX index, reached an impressive 9.4 trillion yen. This trend of corporate overbuying, closely linked to the implementation of share buybacks, is anticipated to persist in the future. In contrast, trust banks and individual investors predominantly engaged in selling, primarily aiming to lock in profits amid the rising index. This profit-taking behavior was a notable counterpoint to the buying trends observed among foreign investors and business corporations.
