🔍 What Is the Nikkei 225?

The Nikkei 225, also known as the Nikkei Stock Average, is Japan’s premier stock market index, representing 225 of the most actively traded companies on the Tokyo Stock Exchange (TSE).

Key Highlights:

• Launched in: 1950

• Managed by: Nihon Keizai Shimbun (Japan’s largest business newspaper)

• Companies Included: Toyota, Sony, SoftBank, Nintendo, Mitsubishi, and more

• Weighting Method: Price-weighted (like the Dow Jones), meaning higher-priced stocks have a bigger impact on the index.

This differs from market capitalization-weighted indices like the S&P 500, where larger companies by market value influence index movements more.

💡 Unique Aspects of the Nikkei 225

1. Price-Weighted Anomaly

Unlike most modern indices, the Nikkei is price-weighted, which can skew its performance due to a handful of high-priced stocks—such as Fast Retailing (Uniqlo’s parent)—dominating index movements.

Investor Tip: Don’t judge the Japanese market solely based on the Nikkei’s movement. Consider complementary indices like TOPIX (Tokyo Stock Price Index), which is market cap-weighted.

2. High Export Exposure

Many Nikkei-listed firms derive a significant chunk of their revenues from overseas markets. This makes the index sensitive to global demand, currency rates, and geopolitical tensions.

3. Government and Central Bank Influence

The Bank of Japan (BoJ) has been an active participant in equity markets, even purchasing ETFs linked to the Nikkei to stimulate the economy—a rare policy among central banks.
