The Nikkei 255 index is a stock market index that tracks the performance of 255 large-cap companies listed on the Tokyo Stock Exchange (TSE). It serves as a benchmark for Japan's economic activity and investor sentiment.
The index is calculated using the Laspeyres formula, which weights each component based on its price relative to a base period. The Nikkei 255 is updated quarterly to ensure it reflects current market conditions accurately.
Unlike the more widely known Nikkei 225 index, which includes only 225 companies, the Nikkei 255 offers a broader representation of Japan's economy by including additional large-cap firms. This makes it a valuable tool for investors looking to gauge the health of the Japanese market.
The Nikkei 255 comprises companies from various sectors, including technology, finance, healthcare, and consumer goods. Some notable constituents include Toyota Motor Corp., Sony Group Corp., and SoftBank Group Corp.
The index is divided into several sub-indices, each representing different sectors or market segments. These sub-indices allow investors to analyze specific areas of the economy more closely.
The Nikkei 255 is primarily used by investors, analysts, and financial institutions to assess the performance of the Japanese stock market. It is also used as a benchmark for investment products such as exchange-traded funds (ETFs) and mutual funds.
For example, the iShares MSCI Japan ETF (EWJ) uses the Nikkei 255 as one of its reference indices. This ETF provides exposure to the Japanese equity market, making it a popular choice for international investors.
One common misconception is that the Nikkei 255 and the Nikkei 225 are identical. While both indices track large-cap companies in Japan, the Nikkei 255 includes 30 additional companies, providing a more complete view of the market.
Another misconception is that the Nikkei 255 is solely focused on manufacturing and automotive companies. In reality, it includes a diverse range of sectors, reflecting the broader economy.
Suppose an investor wants to compare the performance of the Nikkei 255 with the Nikkei 225 over a one-year period. They observe that the Nikkei 255 has outperformed the Nikkei 225 by 2%. This difference can be attributed to the additional companies included in the Nikkei 255, which may have experienced higher growth rates.
By analyzing the components of the Nikkei 255, the investor identifies that the technology and healthcare sectors contributed to this outperformance. This insight helps the investor adjust their portfolio to include more stocks from these sectors.

The Nikkei 255 index is a important tool for understanding the performance of Japan's stock market.
