April 20 (Reuters) – Australian shares snapped a five-day rally on Tuesday as tech stocks tracked an overnight decline in U.S. markets, and earnings-driven losses in fund manager Challenger and rare earths miner Lynas weighed.
The S&P/ASX 200 fell 0.7% to 7,017.80, its worst session since March 30. All sub-indexes ended in negative territory.
All three major Wall Street indexes ended lower on Monday, with the tech-heavy Nasdaq slipping nearly 1%.
“The benchmark is lower tracking Nasdaq which is down quite a bit with the tech-heavy stocks. We are certainly more affected by financials, miners and tech sectors on the local index,” said Dale Raynes, associate director at CPS Capital.
Tech stocks fell 1.2%, dragged by Altium Ltd which was down the most at 5.2%.
Sector heavyweight Afterpay lost 0.8%. The buy-now-pay-later giant said it was exploring a U.S. listing after North America became its biggest market.
Financial stocks gave up 0.9%. Challenger plummeted 15.8%, its worst day since March 2020, as it forecast annual profit at the bottom end of its guidance range.
Miners eased 0.2%, with Lynas slumping 8.5% after its third-quarter revenue and sales volume of rare earth oxides fell from the prior quarter, partly due to the Suez Canal blockage in March.
Raynes said losses in Lynas and Challenger were having a particularly pronounced affect on the market due to a lack of other catalysts.
New Zealand’s benchmark S&P/NZX 50 fell 0.7% to 12678.55. Port and harbour operator Napier Port declined the most, falling 4.2%. ($1 = 1.2832 Australian dollars) (Reporting by Vasudha Kaukuntla in Bengaluru; Editing by Krishna Chandra Eluri)
