Australia’s share market has had its worst session since May 1, and all sectors were punished, as investors followed a big sell-off of technology stocks in the US.

The S&P/ASX200 benchmark index closed lower by 187.1 points, or 3.06 per cent, at 5925.5 points on Friday.

The drop is the steepest since a 5.01 per cent decline on May 1.

The loss also meant the index finished lower by 2.44 per cent for the week.

The All Ordinaries index closed down by 192.2 points, or 3.05 per cent, to 6108.8.

The Aussie dollar was buying 72.68 US cents at 1618 AEST, lower from 73.09 US cents at the close on Thursday.
