Nasdaq's 3% Friday Plunge Ends AI Rally as Big Tech Earnings Fail

The Nasdaq fell nearly 3% on Friday, erasing a week that had started with a more than 2% gain through Wednesday and closing out a 2% weekly loss. The reversal marks a turning point in how Wall Street prices the AI trade: enthusiasm alone no longer carries tech stocks through disappointing earnings.

The tech-heavy index sank 5.3% for October, while the S&P 500 lost nearly 2% for the week and roughly 1% for the month. The Dow told the opposite story — down less than 1% for the week but up 1.7% for the month — as investors rotated out of tech and into defensive names. Healthcare was the best-performing sector of the week. The message from the tape is blunt: money is moving away from AI hype and toward companies with visible cash flows.

What killed the chip rally?

Semiconductors started the week as the market's strongest group. Anthropic's IPO filing reignited enthusiasm for AI stocks on Monday, and SK Hynix's record quarterly profit on Wednesday reinforced confidence in memory demand. The iShares Semiconductor ETF (SOXX) surged roughly 9% over the first three trading sessions.

Then the earnings arrived. Intel issued a weak outlook Thursday evening, and its shares plunged more than 28% on Friday — the worst performer of the week among the portfolio's holdings. Analysts cut their price target and placed the rating under review. Jim Cramer said Friday that he can't rationalize selling Intel after such a big decline.

Portfolio director Jeff Marks offered the sharpest diagnosis in the Homestretch: "The data center story at Intel is still mostly intact, but what we got wrong was the sharp drop in personal computer CPU demand due to the high cost of memory and some execution hiccups." Note what that quote concedes: an execution problem, not a demand collapse — but execution problems are exactly what the market stops forgiving when rates are high.

How did the Fed make it worse?

Expectations remained high for the Federal Reserve to raise interest rates in December. Central bankers held rates steady Wednesday, but Fed Chairman Kevin Warsh talked tough on inflation, signalling it is only a matter of time before another hike.

The prospect of higher rates compounded a specific worry: that tech companies may be borrowing too much in the race to keep building out AI. That concern now has a concrete trigger — Alphabet and Amazon both reported negative free cash flow, and both saw investors scrutinize their capital spending plans. When money costs more, unprofitable build-outs get repriced first.

What did Microsoft, Alphabet and Amazon actually report?

Earnings from the three cloud giants reinforced a shift in sentiment: investors increasingly prioritize financial discipline and a line of sight to returns on AI investments over aggressive spending. That is a meaningful change from 2023 and early 2024, when capital expenditure headlines sent stocks up.

• Microsoft delivered strong results Wednesday. Azure revenue grew 48%, and capital spending came in below expectations. Shares initially rallied before giving back the gains, but the stock lost only 0.5% for the week — a win in a week this bad for tech. Cramer praised management's ability to deliver robust cloud growth while keeping spending in check. The team raised its price target to $580 from $550 and kept a hold-equivalent 2 rating.
• Alphabet faced a much harsher reaction. Shares plunged roughly 12% Thursday, the day after the Google parent missed earnings and revenue expectations and reported negative free cash flow. Strong cloud growth did not offset disappointing advertising results and concerns about its massive AI investments. Alphabet finished the week down 12.6%, the second-worst performer. Analysts stayed encouraged by the cloud business but were not ready to buy the dip.
• Amazon missed earnings and revenue expectations Thursday evening, as weaker retail and advertising results overshadowed accelerating growth at Amazon Web Services. Shares fell 1.4% Friday — a modest decline given the stock was down more than 6% at session lows. AWS revenue grew at its fastest pace in nearly five years, but investors focused on the negative free cash flow and next year's big capital spending plans. Cramer said just after Friday's opening bell: "I think you buy Amazon here." The stock lost 3% for the week.

The pattern across all three reports is consistent: cloud growth is real, but the market now demands proof that AI spending converts into returns. Takeaway: the AI trade has entered its return-on-investment phase.

Who won when tech lost?

Eli Lilly surged more than 6% to a record high Thursday after a beat-and-raise quarter fueled by strong demand for its obesity and diabetes drugs, and extended gains Friday. The stock rose more than 11% for the week, the second-best performer, and analysts raised the price target to $1,500 from $1,300 while keeping a hold-equivalent 2 rating.

FedEx rallied Thursday and Friday — gaining nearly 5% for the week — despite a softer-than-expected current outlook, as investors focused on efficiency and profitability progress under CEO Raj Subramaniam. FedEx Freight, in its first earnings report as a standalone company, topped expectations and surged nearly 15% Friday, making the less-than-truckload (freight shipped in partial loads) stock the best performer of the week. The team still prefers FedEx over its former subsidiary.

Linde posted record quarterly sales and profits, supported partly by semiconductor demand, and gained 1%. Starbucks reported stronger-than-expected profits and comparable sales growth as CEO Brian Niccol's turnaround gained traction; Cramer called it a buy, and the stock rose nearly 3%.

What about GE Vernova and Boeing?

GE Vernova initially struggled despite a beat-and-raise quarter Wednesday and a $9 billion acquisition of grid equipment maker Trench Group. Investors questioned the pace of gas turbine order growth next year, but analysts argued the reaction overlooked strong underlying demand. GEV is not a pure-play AI stock, but it is tied to the data center build-out through electrification — and the Trench deal supports that thesis. Shares rose more than 5% for the week, recovering nearly half of the prior week's decline.

Boeing was the third-biggest loser, tumbling more than 10% Tuesday after management pushed its timeline for $10 billion in annual free cash flow back to 2029. The delay overshadowed a record $745 billion backlog. Analysts kept a buy-equivalent 1 rating but lowered the price target to $225, framing the guidance reset as a potential clearing event. Boeing lost nearly 9% for the week.

Where does this leave the AI trade?

The week's verdict is that Wall Street has changed its priorities: strong AI-adjacent growth earns no pass on weak guidance, negative free cash flow, or heavy borrowing — especially with a December rate hike on the table. Anthropic's IPO filing and SK Hynix's record profit show the underlying AI demand story still has fuel. Whether the next leg of the rally survives will depend on whether Big Tech can show returns on the money it is spending now.
