Stock Market Week Ahead: A Choppy Market Heads For Nvidia Earnings, Jackson Hole

U.S. stocks ended the week on a softer footing, with the Nasdaq and S&P 500 posting their first weekly declines in four weeks. The article says both indexes undercut the low of their Aug. 4 follow-through day, weakening the recent rally and putting the confirmed uptrend in a more fragile state. The Nasdaq also closed below its 21-day exponential moving average, signaling added technical damage, while the S&P 500 remained just above that support line. For Nvidia, investors are watching a pivotal week ahead of fiscal Q2 earnings, with consensus calling for explosive year-over-year growth and the stock already near a cup-base buy point. The broader setup is cautious: market leadership is still emerging, but sector rotation, elevated volatility, and key catalysts like Nvidia earnings and Jackson Hole make this a tricky environment for new buying.
