I just saw in the news that NSE is planning to list some it's shares from June this year, but from an investor point of view I do not see why anyone would like to put their money in NSE . Unlike a normal company with products and/or services that generates revenue or losses for that matter,NSE does not seem to have anything to offer in return for investors' cash.. Or am I missing something??

Nse will be among those illiquid stocks.nobody will be willing to sell especially those stockbrokers and investment banks

As long as we continue trading(I doubt we'll stop) the NSE will always get its share. There is definitely great growth prospects in the NSE

Will buy some

Need to see the prospectus first. But I'd prefer an index ETF (FTSE NSE15 or 25) than owning the shares of an exchange.

Will NSE continue to grow? Yes as well as from other securities they'll launch.
Will it grow at the 2013 pace? Not easy to repeat that growth.
Will NSE face another exchange rival(s) in future? Likely.

Since this KE exchange is still a toddler, I'd rate it a buy as it still has room for growth as EAC econ expands enabling more listings. NSE has a few firms listed (some which hardly trade for days/weeks) compared with JSE or egypt or nigeria exchanges; it's a toddler. Then look at the other EAC exchanges that have lesser listed firms and static trading...
