# Rising bond yields threaten S&P 500’s record-breaking momentum

Rally meets resistance: Record highs in the S&P 500 were disrupted by spiking bond yields, triggering a broad tech sell-off and renewed inflation concerns. Yields keep climbing: Analysts see 10-year Treasury yields potentially reaching 4.75% as inflation expectations rise, pressuring both corporate and consumer borrowing. Tech’s narrow lead: Mega-cap tech stocks may regain market leadership, but concentration in AI-linked names leaves the rally vulnerable to sharp reversals.
