The recent announcement of a $600 billion investment in artificial intelligence by major tech companies has sparked significant concern among investors, as reported by Tribune Latest. This massive spending plan, which includes Amazon's capital expenditure potentially doubling from the previous year, has led to a sharp decline in Amazon's share prices during pre-market trading. The sentiment is echoed across various markets, with the S&P 500 software and services index dropping nearly 10% this week, and India's IT index shedding around 7%. The Nation Business highlights that Asian markets have also been affected, with Hong Kong equities sinking as the tech rout continues to impact Wall Street for the third consecutive day.
