It was done in a perfectly legal manner. Yesterday Prime Minister Shehbaz Sharif announced a ten percent super tax on many industries. Of course this was ostensibly done to increase government revenue and please the IMF. But it was the way he did it that makes one suspect that he had a personal interest in the matter. He made the announcement much before the stock exchange closing time (the announcement should have been done by his finance minister Miftah Ismail in the evening, after the market's closure). The stock market immediately crashed and for a time trading was stopped before re-starting again. In the meantime, Shehbaz Sharif and his friends had reportedly made billions in forward selling and buying.

This was how it was done. They sold millions of shares at high rates and bought them at very low prices. This is the most convenient way to earn money in this market. I used to do it myself fifteen years back. And there is nothing illegal about it. If Imran Khan's finance minister Shaukat Tarin or Asad Umar claim in future that Shehbaz Sharif deliberately did so to enrich himself and his friends, how will they prove it? Shehbaz is not such a fool as to buy and sell shares in his own name. Those who deal in shares suspect that he and his finance minister Miftah Ismail (who is a very distant relative of mine) must have told their close relatives and friends to buy and sell in the futures market a day in advance. Probably big shots like AKD and others also knew that this was going to happen. 

So, if anyone wants to become overnight millionaires dabbling in shares, it's best to make friends with the finance minister or the prime minister.
