Wall Street closes mixed as higher oil prices and growing bets on tighter Federal Reserve policy pull the S&P 500 lower. The Nasdaq 100 ends slightly higher, indicating only modest gains in parts of the tech-heavy market.

In August, the Nasdaq 100 records a broader monthly gain after a prior stretch of losses, suggesting the market’s direction is not uniform across indexes. NDTV links the day’s pressure on stocks to an oil spike, which can raise inflation concerns, and to rising expectations for higher interest rates. Across the reporting, the main focus is on shifts in interest-rate expectations and commodity-driven inflation risk, with the S&P 500 responding more negatively than the Nasdaq 100.

While one index declines and the other holds up, the underlying theme in the available coverage is the same: investor sentiment is sensitive to economic signals that influence the Fed’s next moves, alongside energy-price volatility.
