European Stocks to Watch: OMX

Shares in Swedish bourse operator and technology firm OMX soared more 10.34% following an announcement that the company was in cooperation talks with several exchanges.

The Nasdaq Stock Market reportedly made a $3.33 billion offer for OMX, according to a Swedish newspaper, but the company said it did not receive any formal or informal bids.

This is the latest in a wave of consolidation in the share index market which has seen particular interest in U.S. exchanges tying up with European partners, including the recent failure of the Nasdaq to secure a merger deal with the London Stock Exchange.
