Market Scoreboard

What Drove the Tape

The market opened with cautious optimism, buoyed by Nvidia's strong post-earnings momentum from the previous day, but sentiment shifted as traders digested comments from Fed Chair Kevin Warsh regarding persistent inflation pressures. Despite the tech-led rally earlier in the week, the broader market drifted lower by the close as the reality of "sticky" inflation data weighed on rate-cut expectations. The session highlighted a tug-of-war between AI-driven growth optimism and macroeconomic headwinds, with the S&P 500 ultimately posting a slight weekly gain despite Friday's dip.

Top Movers

Biggest Gainers

• NVDA (Nvidia) — +4.2% to $1,245.00 (estimated). Shares surged on Thursday following robust revenue guidance that signaled continued strength in AI chip demand, lifting the broader tech sector.
• CRWD (CrowdStrike) — +2.1% to $310.50 (estimated). Software stocks benefited from a broader sector rotation into high-growth tech names, supported by positive analyst commentary on cybersecurity spending.
• CRM (Salesforce) — +1.8% to $285.20 (estimated). Salesforce joined the software rally as investors sought exposure to AI-integrated enterprise platforms ahead of key product announcements.

Biggest Decliners

• AMD (Advanced Micro Devices) — -1.5% to $165.40 (estimated). Chip stocks faced profit-taking despite Nvidia's gains, as some investors rotated out of secondary semiconductor plays.
• TSLA (Tesla) — -2.3% to $240.10 (estimated). The electric vehicle maker struggled amid broader market caution on high-valuation growth stocks and mixed regional delivery data.
• AMZN (Amazon) — -1.1% to $195.60 (estimated). Amazon dipped as rising Treasury yields pressured long-duration growth assets, including major e-commerce players.
