Topix: An Overview of the Tokyo Stock Exchange Index

Topix, or the Tokyo Stock Price Index, is a stock market index for the Tokyo Stock Exchange, measuring the performance of its largest companies.

Definition

Topix, short for the Tokyo Stock Price Index, is a stock market index representing the performance of the largest companies listed on the Tokyo Stock Exchange (TSE). It consists of all domestic companies in the TSE’s First Section, which includes the largest and most liquid stocks on the exchange.

Composition and Calculation

Types of Constituents

Topix is a capitalization-weighted index, meaning each company’s weight in the index is proportionate to its total market value. This index includes various industry sectors, providing a broad measure of the Japanese economy.

Calculation Method

Topix is calculated by taking the market capitalization of all First Section companies, adjusting for free-float, and dividing it by a base value. The formula is as follows:

$$ \text{Topix} = \left( \frac{\sum (\text{Current Market Value of Component Stocks} \times \text{Free-Float Adjustment Factor})}{\text{Base Market Value}} \right) \times \text{Base Index Value} $$

The base value, historically set on January 4, 1968, ensures that the index can be compared over time.

Historical Context

Origins and Evolution

Topix was first published in 1969 by the Tokyo Stock Exchange, aiming to provide a more precise reflection of market performance than previously available indices. Over the years, it has become a key indicator of Japanese market trends and an essential benchmark for institutional investors.

Comparison with Nikkei 225

While both Topix and Nikkei 225 are major indices for the Tokyo Stock Exchange, they differ in composition and calculation. Nikkei 225 is a price-weighted index, meaning companies with higher stock prices have more influence. Conversely, Topix offers a broader and more inclusive measure, as it covers all companies in the TSE First Section.
