Stocks dropped yesterday depressed by technology shares, as investors pocketed profits after Wall Street's big run-up.

The market rose over the past week in a rally fuelled by expectations that the conflict in Afghanistan would end swiftly as the hard-line Taliban's rule crumbled following 45 days of attacks by the United States and opposition Afghan forces.
