Nikkei Asia300 index reflects Asian companies' growing momentum
The Nikkei Asia300 Index is a composite stock index comprising over 300 of Asia's most influential listed companies, allowing users to grasp overall stock trends in Hong Kong, China, South Korea, Taiwan, India and six Southeast Asian countries.
In addition to the Asia300, the Nikkei Asia300 ASEAN Index -- which focuses on companies headquartered in the Association of Southeast Asian Nations -- is calculated in real time. Daily closing figures are provided for 11 country and region specific indexes.
Of the 327 companies selected for the Asia300 as of the end of May, 316 of them were included in the calculation, with two listed only in the U.S. excluded. Delisted companies are excluded from the calculation immediately.
The Asia300 is calculated from Monday to Friday except for Jan. 1 between 9 a.m. JST when regular trading starts at the Korea Exchange and 7:20 p.m. JST when it closes at the Bombay Stock Exchange. Stocks are weighted in the indexes by market capitalization. The indexes are calculated by Singapore Exchange.
Data on the indexes is provided in The Nikkei online edition and the Nikkei indexes official website "Profile of the Nikkei Stock Average" (http://indexes.nikkei.co.jp/en/nkave) and by QUICK, a financial information service company in the Nikkei group.
Meanwhile, Nikkei is developing additional indexes based on the Asia300 for use in investment trusts and other financial products, as well as improving convenience for creators of financial products and investors by pursuing easy-to-track investments.
