What Happened

On Thursday, October 22, and Friday, October 23, Wall Street was hit by two very different waves of selling back to back - and the fact that they moved the market in almost opposite ways is the more interesting part of the story.

Thursday's session was dominated by fear over AI spending. The Nasdaq Composite tumbled 2.6% to close at 26,008.86, its largest one-day drop since June. The S&P 500 fell 1.21% to 7,663.43. The Dow Jones Industrial Average, by contrast, barely moved and actually edged up slightly to 52,873.28, lifted by defensive names like Procter & Gamble and Lockheed Martin. At the center of the selling was Meta Platforms (Nasdaq: META), which fell 7% after disclosing roughly $825 billion in forward AI data-center spending commitments alongside $34.91 billion in quarterly capital expenditures and negative $2.12 billion in free cash flow. AMD dropped 8% and Micron fell 6% the same day, while the Philadelphia Semiconductor Index (SOX) plunged more than 6% - its biggest one-day drop since June 23. It was a day when doubts about both the sheer scale of AI infrastructure spending and the cost of financing it spread across chipmakers and megacap tech broadly.

The very next day, Friday, markets were jolted again - but this time for an entirely different reason. The Dow fell 652.82 points (1.23%) to close at 52,215.16, the S&P 500 slipped 0.52% to 7,623.68, and the Nasdaq eased 0.21% to 25,955.34. This time the trigger wasn't AI, it was oil. Reports that the US and Israel were drawing up plans for renewed strikes on Iran after the midterm elections sent West Texas Intermediate crude up 3.6% intraday to as high as $117 a barrel, its highest level since April, while Brent settled at $116.72. The 10-year Treasury yield pushed back toward 5%. Dow component American Express (NYSE: AXP) fell more than 3% after announcing it would cut roughly 5% of its global workforce, explicitly framing the move as preparing for "the AI era."

Here's the detail that stands out: on a day when the broader index fell and most of the S&P 500's eleven sectors were in the red, the technology sector actually gained 0.35%. The very group of stocks that had been the epicenter of "AI fear" just one trading day earlier turned into the best-performing corner of the market on a day driven by an entirely unrelated oil shock. Looking at the full week, the Dow still finished up 0.4%, while the S&P 500 fell 0.5% and the Nasdaq dropped 0.7% - the second consecutive losing week for both of those benchmarks.

Why Tech Flipped From Villain to Survivor in a Single Day

To make sense of this reversal, it helps to separate the two days by the type of shock that drove them. Thursday's shock was a valuation and fundamentals shock. Meta's $825 billion in forward spending commitments and negative free cash flow directly fed doubts about whether AI capital spending has gotten too large relative to any visible payback timeline. That kind of shock triggers a textbook response: investors pull back from risk assets broadly and rotate into defensive names with stable cash flows that have little exposure to either interest rates or the AI spending cycle - which is exactly why Procter & Gamble and Lockheed Martin rallied on Thursday.

Friday's shock, on the other hand, was geopolitical and commodity-driven. A spike in oil prices doesn't change a company's long-term earnings outlook the way a capex disclosure does; instead, it directly raises input costs for fuel-sensitive industries like airlines, shipping, and consumer goods, while simultaneously reviving inflation fears that push Treasury yields higher. Software- and semiconductor-heavy tech, somewhat ironically, has relatively limited direct exposure to crude oil as an input cost, so an oil shock doesn't hit tech's fundamentals the same way it hits other sectors. On top of that, names like Meta, AMD, and Micron had already absorbed nearly three straight days of punishing selling by Thursday's close, leaving more room for bargain-hunters and short-covering to step in. When a stock has already priced in a large share of the bad news, there's simply less incremental reason to keep selling it into a completely different kind of shock the next day.

American Express's case makes this contrast even sharper. AXP's layoff announcement was, broadly speaking, an "AI" story - the company explicitly said it was cutting staff to prepare for the AI era. Yet it was this AI-themed news that sent a financial-sector stock down more than 3%, on the very same day the technology sector itself was rising. In other words, "AI" worked as a tailwind for one group of stocks and a headwind for another, on the same trading day. Markets appear to have read AmEx's move less as a cost-saving positive and more as a signal that consumer spending may be softening, or that AI is displacing jobs faster than previously assumed.

Attention is now turning to next week. The Federal Open Market Committee (FOMC) meets October 27-28, with its rate decision due Wednesday, October 28, at 2:00 PM Eastern time. Markets currently see a hold as the most likely outcome, but with the 10-year yield already near 5% and oil-driven inflation concerns resurfacing, how the Fed frames the oil spike - as a transient shock to be looked through, or as a reason to lean more hawkish - could be the key variable shaping market direction into next week and beyond.

What to Take Away From This

No sector is "defensive" against every kind of shock. Consumer staples and defense stocks were the safe harbor from Thursday's AI valuation scare, but they were not spared from Friday's oil-and-geopolitics-driven selloff, while tech - Thursday's culprit - held up better. What counts as "safe" depends entirely on what kind of risk is hitting the market that day.
The same sector can flip direction depending on the shock's nature. Tech tends to sell off first in a fundamentals or valuation scare, but can hold up relatively well in a commodity or geopolitical shock simply because it has less direct cost exposure to oil. Before reacting to a sector move, identify what specifically is driving the index that day and which businesses that catalyst actually touches.
A stock or sector that already got hit hard can become more resilient to the next shock. Names that absorbed nearly three days of heavy selling had less room to fall further and attracted bargain-buying and short-covering once a new, unrelated catalyst hit. When judging the next day's reaction, ask how much bad news is already priced in.
A single day's index move and a full week's performance can tell very different stories. The Dow fell 652 points on Friday alone, yet still finished the week up 0.4%. The S&P 500 and Nasdaq, despite smaller single-day losses, posted their second consecutive down week. Don't extrapolate a week's trend from one headline number.

FAQ

Why did tech stocks rise on a day when the broader market fell?

Friday's decline was driven by a spike in oil prices and Treasury yields tied to renewed Iran-related geopolitical tension, not by any AI- or tech-specific news. Software- and chip-heavy tech has limited direct exposure to oil as an input cost, so it wasn't hit the same way other sectors were. At the same time, AI-related names like Meta, AMD, and Micron had already been sold heavily on Thursday, leaving room for bargain-hunting and short-covering to lift the sector on Friday.

What does oil at $117 a barrel mean, and why does it move US stocks?

West Texas Intermediate crude's intraday spike to $117 a barrel - its highest since April - was triggered directly by reports that the US and Israel were preparing renewed strikes on Iran. Higher oil prices raise costs for fuel-sensitive industries like airlines, shipping, and consumer goods, and they tend to reignite inflation concerns, which pushes Treasury yields higher. Rising yields increase the discount rate applied to future earnings across the market, which is a headwind for equity valuations broadly.

What should investors watch for at next week's FOMC meeting?

The rate decision itself, due Wednesday, October 28, is widely expected to be a hold, and markets have largely priced that in already. The more important variable is the tone of Fed Chair Jerome Powell's press conference. With oil-driven inflation fears resurfacing just as yields sit near 5%, whether the Fed treats the oil spike as a temporary shock to look past, or leans more hawkish in response, is likely to be the key factor shaping market direction in the weeks that follow.
