What are today's top business/market headlines?

Global financial markets are navigating a volatile weekend following a sharp tech-led sell-off and major geopolitical developments. Here are today’s top business and market headlines:

1. Wall Street Hit by Steep Tech Sell-Off Amid AI Spending Jitters

The high-flying artificial intelligence trade suffered a major setback, leading to a sharp drop in major indices.

•The S&P 500 tumbled 1.2% to close at 7,663.43.

•The Nasdaq Composite plunged 2.6% to 26,008.86—marking its steepest single-day drop since June and landing at its lowest levels since August.

•The Dow Jones Industrial Average finished relatively flat (up just 11.89 points to 52,867.98), showing a strong defensive rotation into utilities, healthcare, and consumer staples.

This rout was largely triggered by Meta Platforms (META). Despite reporting an impressive 26% year-over-year jump in Q3 revenue ($64.6 billion), Meta’s plans to heavily accelerate capital expenditures for AI infrastructure spooked investors. Concerns that the massive capital requirements for AI may not yield immediate financial returns also dragged down the broader semiconductor sector; the Philadelphia Semiconductor Index dropped 6.7%.

2. Oil Surges Above $116 as Middle East Tensions Escalate

Global energy markets spiked sharply after reports that Iran-backed Houthi forces launched fresh strikes on Saudi Arabia's oil infrastructure.

•Brent crude surged past $116 a barrel, hitting five-month highs.

•In response, the U.S. moved to release emergency oil reserves in an effort to stabilize skyrocketing prices.

•While energy stocks (like Chevron, Halliburton, and SLB) saw significant gains, the spike in crude oil has renewed severe fears of sticky, fuel-driven global inflation.

3. SpaceX Rumors Send Telecom Stocks Plummeting

A Bloomberg report revealing that SpaceX is in active negotiations to secure approximately 80,000 cell sites reignited intense competition fears in the telecommunications sector.

•Investors worried that Elon Musk’s aerospace giant is prepping to become a direct competitor in wireless services, causing a massive sell-off of telecom mainstays.

•AT&T (T) dropped nearly 8%—completely overshadowing its strong Q3 earnings beat and raised full-year guidance from earlier in the week.

•T-Mobile US (TMUS) fell over 7.7%, while Verizon also ended the week in the red.

4. U.S. Business Growth Cools Slightly but Input Costs Rise

According to the latest S&P Global Flash PMI data, U.S. private sector activity moderated slightly in October. The Flash US Composite PMI Output Index slipped to 57.6 from September's five-year high of 58.4.

Even with the slight cooldown, demand remains robust: new business orders grew at their fastest clip in four and a half years. However, supply chain delays have reached their worst levels since 2022, and companies are raising selling prices at the quickest rate in four years to offset rising transportation and energy costs. This suggests that consumer inflation pressures could remain persistent.

5. China’s $3.5 Trillion Market Rout Deepens Into Bear Market

Pessimism surrounding the Chinese economy has intensified. The world’s second-largest stock market has now shed $3.5 trillion in value from its peak in May.

The onshore benchmark CSI 300 Index officially crossed into a bear market. International investors are grappling with a prolonged consumption slump inside China, worse-than-expected corporate earnings across banks and EV makers, and a growing realization that Beijing is unlikely to announce a massive, forceful stimulus package anytime soon.
