On Dec. 1, Nikkei Inc. launched a series of stock indexes under the Nikkei Asia300 Index family, bringing together over 300 of Asia's most influential companies. The indexes will be used by the Nikkei Group to carefully track stock price movements of top Asian companies driving global economic growth and to provide comprehensive coverage of the health of the Asian economy.

The Nikkei Asia300 Index tracks the stock prices, converted to U.S. dollars, of the Asia300 group of must-watch companies selected by Nikkei. The Nikkei Asia300 ASEAN Index focuses specifically on companies in six members of the Association of Southeast Asian Nations. Both are computed in real time. Individual indexes for the 11 countries and regions covered in the Asia300 list are calculated daily based on closing prices.
