At present market daily average turnover is around Rs. 500 million. The present market is having serious liquidity problem. Not enough cash coming in to the market. Foreigners are exiting too.
This will create huge selling pressure from the first day of trading of PLC. As a result the price will come down considerably within couple of days. Therefore, I feel you can buy PLC shares in the open market at least at a 25% discount than IPO price.
This is my personal view and not a recommendation.
