What is the Nikkei 225 Japanese stock index?

Nikkei 225

The Nikkei (or Nikkeil 225) index is the most recognised Japanese stock index. It includes the top 225 Japanese companies listed on the Tokyo stock exchange. The Nikkei is considered an important measure of the Japanese stock market and the performance of the country's economy.

Some of the companies listed in the Nikkei index include Fujitsu, Hitachi, Honda Motors, Kawasaki and Mitsubishi. The technology, consumer goods and materials sectors make up around 84% of the index (with the tech sector representing 47% of the index).

Unlike other indices whose stocks are ranked by market capitalisation, the stocks that make up the Nikkei index are ranked by share price. The prices of the shares are denominated in Japanese yen, and its components are revised once a year.

How does it compare to the TOPIX?

The other big index that tracks the Tokyo stock exchange is the TOPIX (Tokyo Stock Price Index). It ranks stocks based on free float-adjusted market capitalisation. The TOPIX also tracks all domestic companies listed in the first section of the Tokyo stock exchange. As of 2017, the first section included over 2,000 companies.

Major differences have been identified between the Nikkei and TOPIX indices. It is often said that the TOPIX is a better representation of Japan's stock market. This is due to the differences in weighting between the two indices and to the greater number of companies included in the TOPIX.

How does one invest in the Nikkei 225 index?

The Nikkei index doesn't allow individual foreign investors to directly buy or hold stocks. However, investors can obtain exposure to the index by purchasing stocks through exchange-traded funds whose constituents correlate with the index. ETFs (exchange traded funds) include a selection of stocks or other securities. As with stocks, ETFs trade during the day and are subject to price fluctuations.

Investors use ETFs for speculative trading strategies, such as margin trading and short selling. Investors can trade the entire market as if they were trading a single stock. By creating a diversified portfolio, ETFs allow investors to meet specific asset allocation needs, such as a 75%/25% stock/bond allocation. Tax-conscious investors can also take advantage of ETFs to reduce fiscal impacts. The unique structure of ETFs allows investors who trade large volumes of ETFs to buy them back to get stocks that they follow.
