Key Themes This Week

AI Spending Meets Investor Doubt

Anthropic's IPO filing on Monday lifted chip stocks. Then Alphabet reported negative free cash flow and fell about 12% on Thursday, its worst day on record. Amazon and Intel disappointed after the close, and Intel fell 28.6% on Friday.

Market Impact

Chip stocks dropped sharply and the semiconductor index lost 7.2% on Friday. Some analysts said companies that miss very high expectations are being punished. Others pointed to strong cloud growth, such as AWS up 39%, as a sign demand remains solid.

A Divided Fed and Sticky Inflation

The Fed held rates on Wednesday, with Beth Hammack and Lisa Cook dissenting in favor of a hike. September's core PCE inflation (the Fed's preferred gauge) was 3.1%. Third-quarter growth came in at 3.4%.

Market Impact

Traders put the odds of a December rate hike very high, according to one market-data site. Supporters of the economy's strength see resilience. Skeptics worry that higher borrowing costs could add pressure to richly valued tech shares.

Middle East Tensions Keep Oil Elevated

A tanker in the Strait of Hormuz was hit by explosive devices on Friday. Traders are also watching the US midterm elections on November 3. WTI crude settled at $104.12.

Market Impact

Energy shares held up better than the rest of the market. Higher fuel costs also feed inflation worries. Some analysts expect prices to stay volatile in the near term, while others note supply from Saudi Arabia has continued.

Top Stories

Alphabet Has Its Worst Day on Record

What Happened

Alphabet reported third-quarter revenue up 25% to $127.6 billion. It also reported negative free cash flow and said spending on data centers will rise significantly in 2027. Its shares fell about 12% on Thursday, erasing roughly $500 billion in market value.

Market Reaction

The drop dragged on the Nasdaq and set the tone for Friday's selloff. Alphabet slipped another 1.4% on Friday and had its worst month on record.

Bullish View

Some analysts pointed to cloud growth of 103% and strong revenue as signs the business is still expanding.

Bearish View

Other analysts noted that spending is rising faster than cash generation. Per-share earnings also fell about 26% from a year earlier as new shares were issued.

Intel and Amazon Results Deepen the Tech Selloff

What Happened

Intel gave weak fourth-quarter guidance and blamed PC weakness tied to higher memory chip costs. Its stock fell 28.6% on Friday, its worst day since 1974. Amazon missed revenue and earnings estimates and reported negative free cash flow of $42.4 billion over 12 months.

Market Reaction

AMD fell 10.9%, Dell 10.8% and HP 9.6%. Amazon cut its early losses and ended Friday down 1.4%.

Bullish View

Some analysts called Amazon's reaction an expectations miss, noting AWS grew 39%, its sixth straight quarter of faster growth, and that management guided for 40%+ growth.

Bearish View

Cautious voices said AI spending now exceeds what many of these firms earn in cash. They noted that stress could spread to credit markets, where CoreWeave's bond yields have climbed near 15%.

Fed Holds Rates in a Split Vote

What Happened

The Fed left its target range at 3.75% to 4% on Wednesday. The vote was 10-2, and both dissenters favored a rate hike. Chair Kevin Warsh said politics played no role and that the Fed will hold fewer rate-setting meetings next year.

Market Reaction

Stocks barely moved after the announcement. Treasury yields drifted lower later in the week as tech stocks fell.

Bullish View

Some observers saw the pause as a sign the Fed is not rushing to tighten further, with solid growth supporting the economy.

Bearish View

Others noted two dissents toward a hike and inflation of 3.6% on the PCE measure, which keeps more tightening on the table.

Hormuz Tanker Attack Lifts Oil

What Happened

A tanker in the Strait of Hormuz was hit by explosive devices on Friday, according to the UKMTO. Houthi attacks on Saudi Arabia also raised supply worries.

Market Reaction

WTI rose 2.1% on Friday to $104.12, a six-month high. WTI gained about 15% in October, and Brent rose about 14%.

Bullish View

Some analysts expect diplomacy to ease supply fears. Iran's government said it welcomes talks, and President Trump said the conflict will wrap up soon.

Bearish View

Other analysts cited a lack of a clear diplomatic path and possible escalation after the midterm elections.

Economic Data Released

Third-Quarter GDP (advance estimate)+3.4% annualized

Expected: +3.1%

The economy grew faster than forecast, up from 2.2% in the second quarter. Some see resilience, while others link strong growth to continued pressure on the Fed.

September PCE Inflation3.6% headline, 3.1% core (year over year)

Expected: Above the Fed's 2% goal

Inflation picked up in September. Core prices rose 0.3% on the month, which kept talk of a further rate hike alive.

Federal Reserve DecisionHeld at 3.75%-4%, 10-2 vote

Expected: Hold widely expected (about 90% odds)

The hold was expected, but two dissents for a hike showed a divided committee.

Employment Cost Index (Q3)+0.8% quarter over quarter

Expected: +0.8%

Wage costs matched forecasts. Wages and salaries rose 0.7%, slower than the prior quarter. That offered a small sign of easing labor costs.

Historical Perspective

Comparison

Nasdaq's 7.8% pullback from its record is smaller than the 10% drop that defines a correction. Its worst month since March 2025 shows how fast sentiment can shift after strong runs.

Perspective

Historically, markets have often swung sharply during earnings seasons when expectations were high. Pullbacks have been common even in long uptrends. Learning about managing risk can help put weeks like this in context.
