  • The Topix Core 30 Index is a market index composed of 30 of the largest companies listed on the First Section of Japan's Tokyo Stock Exchange, or Topix. 
  • The Topix Core 30 is one of several different Topix indexes. 
  • The Topix Core 30 Index measures the performance of the 30 companies, which are both highly liquid and have the largest market capitalizations.
  • Because the Topix Core 30 focuses only on the top 30 stocks, it is indicative of the growth of the Japanese economy.

Understanding the Topix Core 30 Index

The Topix Core 30 is an index of the 30 most liquid and highly capitalizedౠ stocks of the over 1,500 com💎panies listed on the Topix index.

The name Topix is an acronym for 澳洲幸运5官方开奖结果体彩网:Tokyo Stock Price Index, and Topix lists all Japanese companies of the Tokyo Stock Exchange’s First Section. Topix is one of two widely followed index families on the Tokyo Stock Exchange, the other being the Nikkei.

In terms of the method of calculation an🍨d the use of the index, the Topix indexes can be thought of as being similar to the S&P indexes used in the United States. The Nikkei index is most similar to the Dow Jones Industrial Average index in 🥂the United States.

The Topic Core 30 is an 澳洲幸运5官方开奖结果体彩网:exchange-traded fund (ETF🎃) of stocks chosen and weighted by market capitalization. The Topix Core 30 is managed by Nomura Asset Management꧙ and operated by the Tokyo Stock Exchange. Dividends are paid on July 15 of every year.

Because the Topix Core 30 focuses only on the top 30 stocks, it is indicative of the growth🌟 of the Japanese economy, but not of any market details, and it does not expre🐼ss any events or trends within industries or of the breadth or depth of the Japanese economy as a whole.

Change in Weighting

From 2005 through 2006 a change in the way companies were weighted in the Topix Core 30 was phased in. Previously companies were weighted by the total number of shares outstanding for the company. This privileged companies that had many shares, evenꦐ if the company itself or its business partners owned most of those shares so they could not♉ be traded.

The market transitioned to weighting companies by theꦐ number of shares they had available for trading. This is called “free float,” and it privileges companies that are available to trade for investors and trad♐ers. This change made the Topix Core 30 more democratic, accessible, and responsive to trading activities.
