S&P 500, Nasdaq futures edge up as chip stocks gain; US-Iran tensions in focus - Reuters

Equity index futures are trading modestly higher, with semiconductor stocks emerging as the primary growth driver in pre-market activity. This selective strength in chip equities reflects renewed investor appetite for technology exposure, potentially signaling confidence in demand forecasts or relief from prior supply-chain concerns.

The headline tension between the US and Iran introduces a geopolitical risk overlay that could influence commodities and defense spending narratives. However, the modest futures gains suggest markets are currently pricing this as a manageable headline rather than a systemic shock, maintaining risk-on positioning in growth equities.

The divergence between chip strength and broad-based index gains indicates sector rotation dynamics rather than uniform market enthusiasm. Technology's outperformance likely reflects rotation back into AI and semiconductor plays after prior rotation cycles, with earnings visibility in chip manufacturers supporting tactical positioning.

Sector implication: Technology remains the performance leader, while geopolitical uncertainty creates a bid for defensive and energy assets as portfolio hedges. The muted overall gain magnitude suggests investors are maintaining measured positioning pending clarity on Iran escalation and its macroeconomic spillover effects.
