Its simple. There is no confidence in Pakistan and its political set up. Its not that hard. Companies that need to build capital quickly sell their shares at a lower value so that the investor can make a quick profit and stay on based on the idea that they have made a profit and will make more.
Its standard investment economic thinking.
If you sell stocks at current value few will buy because they don’t see any profit realization in the near future. If you sell stakes at a lower price, they realize a profit right off the bat.
