ASX 200 tech shares' Tuesday tumble
ASX 200 tech shares are suffering after the US tech-heavy index tumbled amid continued concerns about rising interest rates.
The Nasdaq Composite ended yesterday's session in the red, as did the S&P 500 Index (SP: .INX) and the Dow Jones Industrial Average Index (DJX: .DJI). The latter indexes fell 3.2% and 1.99% respectively on Monday.
Their continued downturn follows the US Federal Reserve's decision to raise interest rates by 0.5% last week, according to reporting by Reuters.
Nasdaq giant Tesla Inc (NASDAQ: TSLA) was one of the index's biggest weights overnight, recording a 9% fall.
Back on the ASX on Tuesday, the tech sector is being dragged down by Block Inc (ASX: SQ2). Its share price is tumbling 10.27%.
Meanwhile, stock in NextDC Ltd (ASX: NXT), Computershare Limited (ASX: CPU), Novonix Ltd (ASX: NVX), and Altium Limited (ASX: ALU) are recording drops of 4.6%, 2.6%, 2.2%, and 1.7% respectively.
Though, it's not all dire among the ASX's biggest tech stocks.
Shares in Life360 Inc (ASX: 360), Tyro Payments Ltd (ASX: TYR), and Iress Ltd (ASX: IRE) are leading the sector. They're gaining around 3.9%, 2.4%, and 2.1% respectively.
The Xero Limited (ASX: XRO) share price is also in the green.
The ASX 200 tech sector has plummeted more than 23% since its most recent high in early April. It's also more than 33% lower than it was at the start of 2022.
