Multiple credible and relevant market reports from authoritative financial news outlets consistently describe a period when US equities — including the S&P 500, Dow, and tech-heavy Nasdaq indices — declined in tandem. Several sources specifically mention that the Nasdaq 100 or Nasdaq Composite fell by roughly 1.5% during a broader market downturn, with declines attributed to pressures on megacap tech stocks and macroeconomic concerns. These accounts provide primary, timely market data indicating the stated percentage drop occurred during a wider US equity market slide. There are no direct contradictions among the cited sources, though some reference the Nasdaq Composite rather than the Nasdaq 100 specifically; however, given their close correlation in daily movements, the evidence strongly supports the statement's truthfulness. The convergence of independent reports, with high authority and relevance, yields high confidence in the assessment.
