Trading Day: What war? Chip-led rally helps markets ignore on-again, off-again US-Iran truce - Reuters

Markets demonstrated a pronounced risk-on rotation during today's session, with semiconductor equities leading a broad equity advance despite unresolved geopolitical tensions between the US and Iran. The strength in chip stocks—particularly mega-cap names like NVDA and AMD—suggests investor appetite for high-beta tech exposure remains intact, overriding near-term macro uncertainty.

The disconnect between geopolitical headlines and equity momentum reveals selective attention bias in current market conditions. While US-Iran truce negotiations remain fluid and unpredictable, institutional buyers appear comfortable prioritizing semiconductor upside catalysts—likely driven by AI infrastructure demand and data center spending expectations—over tail-risk positioning.

This price action indicates momentum dominance over fundamentals-based caution. Investors are treating geopolitical volatility as background noise rather than a primary portfolio driver, a posture that typically persists until an unexpected escalation forces repricing. The chip-led rally's breadth suggests confidence in tech earnings trajectories despite macro headwinds.

Sector implication: Technology's outperformance reinforces the current growth-over-value regime. However, this reliance on a single sector for market support creates concentration risk if semiconductor momentum falters or if geopolitical developments suddenly demand capital reallocation toward defensive assets.
