Paris – 19 June 2013 NYSE Euronext (NYX) is extending its range of stockmarket indices with the addition of the CAC 40® Ext, which tracks the market’s benchmark CAC 40®, 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 CAC 40®.  The CAC 40® Ext index is calculated on the basis of CAC 40® index future traded on the NYSE Liffe exchange, adjusted for dividends and interest payments.

With the CAC 40® Ext index, investors can track trends in the CAC 40® – a reliable reflection of the state of the French economy – outside normal trading hours, and take positions at pre-market and after-hour sessions on NYSE Euronext’s regulated European market. The CAC 40® Ext is also a response to strong demand from the many issuers of structured products that want to use it as an underlying index to expand their range of products for investors.

“The launch of the CAC 40® Ext index represents real progress in the trend that began with the introduction of extended trading hours for certain stockmarket 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 when markets are already moving and futures contracts are being traded,” said Fabrice Rahmouni, Index Designer at NYSE Euronext.

“Investors can now take positions before and after the regular trading day in all CAC 40® warrants and turbos 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.
