The KSE 100 points index plunged by 1,419 points to settle at 33,100.34 points.
Arif Habib, the President of KSE, said that the index lost because of panic selling mainly by foreign investors.
"But the opportunities are there and we think the market will gain later this week," he said.
He said that the trend witnessed in the KSE was in line with nearly all global share markets that have been bearish amidst concerns over the slowdown in the Chinese economy and political instability in Greece.
The exchange rate of the US dollar also showed marked appreciation in the interbank and open market.
In the interbank the dollar appreciated by Rs 2.10 to reach a 17-month high of Rs 104.10 but came down to 103.90 at close.
According to an analyst there were fears that some dominant exporter groups are trying to create instability in the market by buying US dollars in huge quantity and there was growing demand for the greenbuck because of the impending Haj season.
