The Australian share market closed flat after a rollercoaster day caused by conflicting reports about US-Chinese negotiations.
The benchmark S&P/ASX200 index finished Thursday up 0.4 points, or 0.01 per cent, to 6,547.1 points, while the broader All Ordinaries was down 4.1 points, or 0.06 per cent, to 6,662.9 points.
"What a flip-flopping day it's been," said CMC Markets chief market strategist Michael McCarthy.
The ASX began the day with a strong rally, gaining 22 points in the first hour of trade, then lost 38 points in the next hour, only to rebound by 30 points in the following 40 minutes.
The local bourse then steadily lost ground from 1240 AEST until 1528 AEST, falling 32 points, before finishing the last half hour of trade with a 17-point rally to close the day almost exactly where it began.
"It's been all over the shop today," Mr McCarthy said.
"A very rough day for day traders, very hard to gauge the day."
Mr McCarthy blamed the volatility on conflicting reports on the expectations for US-China trade talks, set to begin later on Thursday in Washington.
