-Someone with experience,kindly share your views !

Sensex and nifty only represent 30 and 50 stocks respectively.
Fall in nifty and sensex does not mean each and every stock of these indices has fallen.
The stocks mentioned in your link are b,s,t,z categories.
Except b all other categories contains small cap and illiquid stocks.
Z category conains stocks of companies that fail to comply exchanges norms.
these stocks are generally punters stock and lot of manipulation is done.
Stay away from these categories unless and untill u are 100% sure about compnies fundamentals and managements.
