KARACHI, Jan 15 (Reuters) - The Pakistani stock market fell by three percent Tuesday after the Supreme Court ordered the arrest of the prime minister over possible corruption charges.
Investors, who were already trading cautiously due to a protest march led by a Sunni cleric in the capital of Islamabad, aggressively sold shares after the announcement that the court had ordered the arrest of Prime Minister Raja Pervez Ashraf.
It is only the fourth time that the Karachi Stock Exchange has fallen by more than 500 points. The last time was in May 2008, when equities fell due to the impact of global financial crises.
Trading volumes remained high due to extreme volatility.
Investors will be closely watching further political developments, said dealer Samar Iqbal at Topline Securities.
