The NASDAQ isn't exactly our usual beat here at Engadget, but it's not every day that a consumer electronics market segment gets elevated to the status of having its own index, which is what the stock exchange has now done with a little help from the Consumer Electronics Association. They've teamed up for the NASDAQ OMX CEA Smartphone Index, which consists of 84 companies that are involved in one way or another with the "building, design and distribution of handsets, hardware, software, and mobile networks associated with the development, sale and usage of smartphones." We're having a bit of trouble tracking down the complete list of companies included in the index, but it does apparently have the usual suspects like Apple, Google and RIM, and it has started out with a valuation 250.00.
