NYSE Euronext lanceert AEX® Ext index

Back

Amsterdam – July 31, 2013: NYSE Euronext (NYX) is extending its successful range of indices with the addition of the AEX® Ext index. The new index tracks the market’s benchmark AEX-Index®, but with extended calculation and distribution hours, from 8.00 am to 6.30 pm CET compared with 9.00 am to 5.30 pm CET for the AEX-Index®. The AEX® Ext index is calculated on the basis of the AEX-Index® future traded on NYSE Liffe (FTI), adjusted for dividends and interest payments.

The AEX® Ext index enables investors to track trends in the AEX-Index® outside normal trading hours, and to take positions at pre-market and after-hour sessions on NYSE Euronext’s regulated European market. The AEX® Ext is the second extended index launched by NYSE Euronext, after the launch of the CAC 40® Ext last month.

“The launch of these two extended indices represents real progress in the trend that began with the introduction of extended trading hours for certain stock market products in the second half of 2012. It will allow investors in these products to take advantage of price fluctuations before the market opens and after it closes,” said George Patterson, Head of NYSE Euronext’s European Index Group.

“Investors can now take positions before and after the regular trading day in all AEX® warrants and leveraged products that are availablefor extended hours. Until today, extended trading hours were particularly attractive for currency – and commodity-indexed products that trade around the clock and around the globe, and for underlying US contracts, whose market is open until 10.00 pm CET,” he added.
