Sydney - Investors deserted Australian stocks Wednesday in response to a fall on Wall Street.
The ASX 200 lost 146 points, or 3.3 per cent, to 4,146.
Bell Potter Securities analyst James Waggett said the most interesting moves were from the giant miners BHP Billiton Ltd and Rio Tinto Ltd, the latter a takeover target for the former.
While BHP lost almost 5 per cent, Rio was up almost 7 per cent, indicating that traders were factoring in a greater likelihood that BHP would succeed with its hostile merger.
