S&P 500 and Nasdaq Close Mixed Amid Inflation Worries

- Major US indices posted modest declines on August 28-29, 2026, with the S&P 500 down 0.25% at 7,711.76 as Fed commentary highlighted persistent inflation pressures.
The S&P 500 and Nasdaq Composite wrapped the week with small losses after Federal Reserve Chair Kevin Warsh signaled ongoing inflation vigilance, pushing yields higher and pressuring growth stocks. Chip names such as Nvidia and Intel weighed on the tech-heavy Nasdaq, which fell 0.52%.
Despite the Friday dip, both indices finished the week modestly higher, showing resilience. Bond market moves and oil volatility remain the dominant drivers, with traders eyeing upcoming PCE readings and any de-escalation in geopolitics.
Defensive sectors including healthcare and staples held up better, while cyclicals faced rotation pressure. Market participants should watch VIX levels, Treasury yield curves, and earnings revisions from mega-caps for clues on whether the inflation narrative intensifies or fades.
