US Stocks Tumble: Tesla Plunges Over 14%, Alphabet Slides 6%+, Dow Sinks 600 Points

U.S. stocks sold off sharply on July 23, with all three major indexes sinking deep into the red. A brutal tech rout led the decline after Tesla's disappointing Q2 results and Alphabet's record AI capex raised negative free cash flow alarms. Escalating Middle East tensions pushed Brent crude above the $100 per barrel mark, amplifying inflation worries, while rising Treasury yields added further pressure. At session lows, the Dow Jones tumbled more than 600 points, with the Nasdaq and S&P 500 sliding in tandem.

Across sectors, the electric vehicle space was battered across the board—Tesla cratered over 14%, its worst post-earnings single-day drop since 2013. Tech and AI names broadly weakened, with Alphabet down more than 6% and Nvidia following lower. Bucking the trend, industrial metals surged, led by Cleveland Cliffs jumping over 17%. Bitcoin miner MARA Holdings gained over 4%, while American Airlines tumbled more than 8%.

EV Sector Crumbles as Tesla Plunges Over 14%

As of the latest update, Tesla (TSLA) plummeted 14.25% to $320.72, with trading volume exceeding $26.3 billion—tops across the entire market. Ford (F) shed 2.60% to $14.05, Rivian dropped 3.70%, and Lucid tumbled nearly 8%.

Tesla's Q2 results showed adjusted earnings per share of just $0.33, well below the $0.50 analysts had expected. While revenue of $282.4 billion topped estimates, operating margins narrowed sharply to just 1.4%, and a surge in capital expenditures pushed free cash flow into negative territory. Former President Jon McNeill attributed the margin compression to aggressive discounting aimed at sustaining revenue growth. Investors found updates on Optimus robots and Robotaxi scalability underwhelming, with analysts flagging execution risks and the absence of a clear return timeline.

Tech Sector Broadly Weakens as Alphabet Sinks Over 6%

At last check, Alphabet (GOOGL) dropped 6.47% to $319.94 on roughly $16 billion in volume. Nvidia (NVDA) fell 1.73% to $208.40, while Amazon slid 3.73%.

Alphabet's Q2 report revealed a record $44.9 billion in capital expenditures, driving the company to its first quarterly negative free cash flow since its IPO—despite cloud revenue surging 82% year-over-year. The company raised its full-year 2026 capex forecast to between $195 billion and $205 billion. Analysts noted that profit growth was largely fueled by unrealized gains on equity investments in SpaceX and Anthropic rather than operating cash generation. Additionally, Alphabet announced it would begin selling custom TPU systems directly to customers, officially entering the on-premises AI chip market and setting up a head-to-head rivalry with Nvidia.

Industrial Metals Defy the Selloff — Cleveland Cliffs Surges Over 17%

Cleveland Cliffs (CLF) soared 17.09% to $11.07 on volume exceeding 49 million shares. The U.S. 10% baseline tariff is set to expire on Friday, with White House Trade Representative Greer expected to unveil a replacement framework on Thursday. Markets anticipate the new tariff regime will continue to support domestic steel producers. MARA Holdings (MARA) gained 4.31% to $12.95, lifted by a rebound in Bitcoin prices that buoyed mining stocks. American Airlines (AAL) sank 8.08% to $13.60 after the carrier cut its Q3 earnings guidance.

On the macro front, escalating Middle East conflict drove Brent crude above $100 per barrel, with Trump warning that Iran would be held accountable if Houthi forces launch attacks. The oil spike intensified inflation concerns, reinforcing expectations that the Federal Reserve will maintain a hawkish stance, sending the 10-year Treasury yield higher. The U.S. 10% baseline tariff expires Friday, and Trade Representative Greer's Thursday announcement is expected to impose new levies on select imports under Section 301 of the Trade Act, ensuring a seamless transition between the old and new tariff measures.
