BSE500 Replacement Candidates

According to me, any financial index should represent a diversified view of an economy. BSE500 is one such index which represents 93.2% of the total market capitalization of all the stocks listed on BSE. Due to my personal reasons, I feel the following stocks should not be part of BSE500 and should be removed from it as early as possible:

Company
Aftek
Cals
GTL Infrastructure
Ispat Industries
Karuturi Network
NDTV
Nirlon
NOCIL
Noida Toll Bridge

You can also think that these are possible candidates which can be removed from BSE500 in near future.
