July 23 (Thursday) U.S. stock market closed broadly lower, mainly driven by concerns over AI spending after the earnings reports of Alphabet (Google’s parent company) and Tesla, as well as a sell-off in technology stocks.3335

Major index performance (July 23 close)
•S&P 500: 7,408.30 points, down 90.66 points (-1.21%)
•Nasdaq Composite: 25,137.69 points, down 553.21 points (-2.15%)
•Dow Jones: 51,711.65 points, down 506.93 points (-0.97%)
Technology stocks led the decline, with the Nasdaq posting the largest drop. The VIX (fear index) edged up to 18.81, indicating that investors’ risk-avoidance sentiment has warmed.35
Key drivers
1Alphabet (GOOGL) earnings: Q2 revenue $119.8B (above expectations) and cloud business growth up 82% to $24.8B (strong, AI-driven). However, an increase in its capital expenditure guidance sparked investors’ concerns about the high cost of heavy AI investment, and the stock fell at one point after the bell.19
2Tesla (TSLA) earnings: Revenue beat expectations ($28.24B), but adjusted EPS of 33 cents was below expectations, and net profit declined year over year. Pressure in the auto business weighed on the stock.23
3Broader concerns: sustainability of AI spending, elevated valuations for semiconductors/technology, oil price volatility (geopolitical factors), etc. Chip stocks were under pressure overall.38
Outlook for today (July 24, Friday)
•Pre-market/futures: Data is limited, but after the prior day’s sharp drop, there may be a technical rebound or sideways trading near lows. Watch oil prices (Brent had surged), geopolitical risk, and more earnings reports.
•Upcoming to watch: more tech/semiconductor earnings and macro data (such as jobs). This week’s overall market is being tested by earnings season; AI remains the focus, but volatility has increased.25
User background reminder (based on your investment preferences): You’ve been following KO, TSMC, MSTR, and SpaceX IPO-related matters, as well as IBKR/Schwab operations. Tesla and Google are recent hotspots—consider keeping an eye on their future price action and technical indicators (such as RSI and DMI). If you have positions, pay attention to risk management (such as limit orders). The overall market is still at a high level, and defensive sectors (like utilities) are relatively steadier.
