March 30 (Reuters) - Australian shares gave up early gains
on Tuesday to trade lower as heavyweight miners declined in
tandem with copper prices, although a bounce-back in technology
stocks limited losses.
The S&P/ASX 200 index was down 0.3% to 6,781.00 by

the day's declines. S&P 500 E-minis futures were down
0.25 points, or 0.01%, on Tuesday.
