There's an article sitting on the floor right next to me about the NYSE (NYX) getting a little lonelier. The exchange is parting ways with its antiquated methods of implementing trades and moving towards a purely electronic platform. This is where Nasdaq already is. In today's age, faster means better. Instant fills are about the only thing investors accept.
The Nasdaq and LSE deal, if it goes through, would create a dominant world exchange. All they would need to do is merge with and exchange in Asia, and the world would be available to all investors 24 hours a day.
That's the direction the world is heading. LSE... you might was well embrace it.
