Asian equity markets retreated on Wednesday, weighed down by growing caution over stretched valuations in the technology sector.

The sell-off was most pronounced among semiconductor and AI-related names, as traders adopted a wait-and-see stance ahead of Nvidia’s upcoming quarterly earnings report.

The chipmaker’s results are widely viewed as a bellwether for the broader artificial intelligence investment cycle, making the pre-earnings period a time of heightened sensitivity for the sector.

The Nikkei 225 and South Korea’s Kospi both posted losses, reflecting the broad-based pressure on growth stocks.

Market participants are also bracing for the release of US non-farm payrolls data later in the week, which could further influence risk appetite and Federal Reserve policy expectations.

The combination of corporate earnings uncertainty and macroeconomic data has created a cautious trading environment across the region.
