(Sharecast News) - Asia-Pacific markets concluded trading with a mixed bag of outcomes on Tuesday, as some regions extended their gains from the previous day, buoyed by a resurgence in tech stocks on Wall Street.

Investors were also evaluating preliminary business activity data from Australia and Japan.

"Most Asian stock markets are experiencing gains, influenced by the positive performance of global markets and a reduction in concerns about a larger conflict in the Middle East following measured counterattacks by Iran and Israel," said TickMill market analyst Patrick Munnelly.

"Traders are also taking advantage of buying opportunities as they await the release of various important US economic reports on personal income and spending.

"However, concerns are mounting in the markets regarding the possibility of the US Federal Reserve refraining from cutting interest rates throughout this year."

Munnelly said speculation was arising that the next move in US rates could lean towards an increase.

"In the UK, March government borrowing surpassed expectations, leading to a £7bn overshoot in the full-year deficit for 2023-2024 compared to the Office for Budget Responsibility's forecast."
