In 60 seconds: Wall Street opened sharply lower on Thursday, October 22, as disappointing earnings from Tesla, Meta and Lam Research revived fears about Big Tech's AI spending — while Brent crude surged past $112 a barrel on rising Iran tensions. If your 401(k) is flashing red this morning, here's the short version: don't panic-sell. Investors who sit tight through days like this usually come out ahead.
Thursday delivered the one-two punch markets hate most: doubts about the AI boom's payoff, and an oil spike that smells like inflation. Nasdaq-100 futures dropped about 1.9%, threatening to erase much of the index's 2.2% gain for the week. Here's what actually happened, why it matters, and — the part you probably care about most — what it means for your retirement savings.
- Nasdaq-100 futures fell ~1.9%, S&P 500 futures ~1.1% and Dow futures ~0.7% in early Thursday trading as AI-spending worries resurfaced.
- Tesla dropped ~5% despite beating earnings; Meta slipped; chip stocks including Intel, AMD and Micron fell 3–5%.
- Brent crude jumped ~3% to $112 a barrel — near a five-month high — on Iran fears and fresh Houthi attacks on Saudi energy sites.
- For 401(k) savers: red days like this are normal. Panic-selling locks in losses; checking your allocation beats checking your balance.
- What to watch: whether oil holds above $110, how Friday's session opens, and the rest of Big Tech's earnings.

What happened
U.S. stock futures slid on Thursday morning as a fresh round of Big Tech earnings landed with a thud. Nasdaq-100 futures dropped about 1.9%, S&P 500 futures fell around 1.1% and Dow futures slipped roughly 0.7%, according to Reuters and Bloomberg.
The trigger was earnings — or rather, what the earnings said about spending. Tesla fell nearly 5% in premarket trading despite beating profit expectations, after it cut its annual capital-expenditure forecast and flagged heavier investment ahead in robotics, the Cybercab and its Terafab project. Investors read that as a question mark over the pace of its AI and robotics expansion.
Meta slipped too, even after posting strong revenue. Its earnings were dented by legal expenses tied to a teen mental-health settlement, and it introduced new non-voting shares to help fund its AI push — a move that revived scrutiny of just how much cash the AI race demands. Chip-equipment maker Lam Research plunged more than 7% on a disappointing outlook, and IBM dropped 6.5%. Honestly, the market's message was blunt: beat the numbers all you want — show us the returns on the spending.
Latest verified facts
Here's the damage as of Thursday morning, all from Oct. 22 reporting:
Chip stocks were hit across the board: Intel fell 5.1%, while AMD, Qualcomm, Marvell, Broadcom and Micron dropped between 2.9% and 5.3%. South Korea's Kospi closed down 3.5%, Europe's Stoxx 600 fell about 1%, and even Hermès tumbled 7% after reporting zero sales growth in China. French government bonds sold off too.
Oil was the other half of the story. Brent climbed more than 3% to around $112 a barrel after President Trump said Wednesday that Washington is not negotiating with Tehran, and after Saudi Arabia's energy ministry said air defenses intercepted a Houthi drone targeting Aramco's Shaybah oil field. The U.S. has ordered some diplomats to leave Saudi Arabia over the Houthi threat — a story we covered earlier this week. A flight to safety pushed the 10-year Treasury yield down to about 5.085%.
Two market voices summed up the mood. Santiago Mateo of CaixaBank Asset Management told Bloomberg: "The market is still willing to reward heavy AI investment, but is becoming much more demanding about returns." And Ben Barringer of Quilter Cheviot put it more bluntly: "The problem here is that expectations are quite high going into the quarter... you've got to smash it out the park to get your stock to work."
Why it matters
This isn't just a bad morning for day traders. It's the market asking the trillion-dollar question out loud: when does all this AI spending start paying for itself? Wednesday's relief rally — sparked by strong results from SpaceX and Super Micro — evaporated overnight. Even Meta fell despite showing evidence its AI investments are starting to work. The bar for Big Tech is now impossibly high, and anything short of spectacular gets punished.
The oil spike makes everything worse. Crude near $112 threatens to reignite inflation, which could force the Federal Reserve to keep interest rates higher for longer — and high-growth AI stocks are the most sensitive to borrowing costs. It's a pincer movement: doubts about earnings on one side, inflation risk on the other.
Impact on the USA and the world
For American households, the most immediate pain lands at the gas pump if crude stays elevated — and in grocery bills if energy costs feed through to prices. Globally, the selloff spread fast: Asian chip stocks sank, European markets fell across the board, and Bitcoin posted its biggest drop in two weeks as investors fled anything risky.
For anyone with a stock-heavy 401(k), a day like Thursday shows up as a smaller number on the screen. That's the part that stings. So let's talk about it directly.
What happens next
Here's the 401(k) playbook for a day like today — general information, not personal financial advice:
Don't sell into the drop. This is the mistake that actually costs people money. Selling after a selloff turns a paper loss into a real one, and decades of market history show that missing just a handful of the best recovery days can gut long-term returns. The investors who win are usually the ones who did nothing.
Check your allocation, not your balance. If your target-date fund or your stock/bond mix still matches your age and timeline, Thursday changed nothing about your plan. A rebalance back to your target percentages — selling a little of what's held up, buying a little of what's down — is the disciplined move. It's also the opposite of what panic tells you to do.
Keep contributing. If you're still working and contributing every paycheck, down days are when your dollars buy more shares. Dollar-cost averaging isn't exciting, but it's the closest thing to a free lunch in investing.
Keep an emergency fund separate. The real danger of a market drop isn't the portfolio — it's being forced to sell because you need cash. Three to six months of expenses in a boring savings account is what lets you ignore days like this.
What to watch from here: whether Brent holds above $110 (that's the line between a scare and a real inflation problem), how Wall Street opens on Friday, the rest of Big Tech's earnings, and any fresh headlines out of Iran. Read our earlier coverage of last week's $1 trillion AI-jitters selloff for the bigger picture — this week's drop is the same argument, resumed. If Friday brings calmer trading and oil cools off, Thursday goes down as a one-day scare. If not, buckle up: the AI-spending debate is just getting started.
