The S&P/ASX 200 is poised to open lower, weighed down by a reversal in US equity markets where technology stocks are exerting significant downward pressure.

Despite broader gains across Wall Street indices, the underperformance of key tech names has kept the S&P 500 mostly unchanged after it erased early losses, signaling fragility in the current rally.

Australian equities are facing immediate pressure as Wall Street reversed earlier gains, with selling concentrated in the technology sector.

The divergence between broad market resilience and tech-specific weakness suggests that investor appetite for risk remains selective, particularly in growth-oriented assets that have driven much of the recent market momentum.

This dynamic highlights the continued sensitivity of global markets to US tech performance.

As the ASX prepares to open, traders will be watching for signs of whether the US tech sell-off is a temporary rotation or a deeper correction that could spill over into other sectors and regions.
