It's a make-or-break moment for the AI trade.

Four trillion-dollar companies report in the span of about 24 hours. Microsoft Corp. (NASDAQ:MSFT) and Alphabet Inc. (NASDAQ:GOOGL) open their books Wednesday after the close. Eli Lilly and Co. (NYSE:LLY) follows Thursday morning, and Amazon.com Inc. (NASDAQ:AMZN) closes the run Thursday after the bell.

Together, the four are worth about $11.7 trillion.

The timing adds another layer. The Federal Reserve announces its rate decision on Wednesday at 2 p.m. ET, roughly two hours before Microsoft and Alphabet report. Third-quarter GDP and the September core PCE price index land Thursday morning.

None of the four giants makes this week's list of widest expected moves, though. Options traders are pricing the biggest swings in the companies that build, power, cool and connect the AI buildout.

The setup comes after a week that rattled the AI trade, with the iShares Semiconductor ETF (NASDAQ:SOXX) down 15.7% since the start of the month.

These are the 12 largest expected movers of the week among U.S. stocks with at least $50 billion in market cap, according to market data. Eleven are priced for swings of at least 10%, and SanDisk sits just below that mark.

Seven of the 12 sell chips, power, cooling, fiber or storage into AI data centers.

An implied move is the percentage swing in either direction that options traders expect right after earnings.

Which Stocks Could Swing The Most This Week?

12. SanDisk: 9.44% Implied Move

No stock on the list has run harder this year. SanDisk shares are up 437% in 2026, making the flash-memory maker the poster child of the AI storage boom.

That run is now under pressure. Memory makers lost $1 trillion in market value during the chip sell-off in mid-October.

SanDisk reports its fiscal first quarter Oct. 29 after the close. Analysts expect earnings of $46.22 per share on revenue of $10.64 billion.

The previous report did not land well. On Aug. 6, the session after its fiscal fourth-quarter results, the stock fell 6.8%. Still, Mizuho raised its price target to $2,050 on Oct. 6, and Rosenblatt started coverage at Buy with a $2,400 target in September.

The key questions are NAND pricing, demand from AI data centers and whether margins can keep expanding.

SanDisk Corp. (NASDAQ:SNDK) stock has more than quintupled in 2026, soaring 436.9% since the start of the year.

11. Howmet Aerospace: 10.00% Implied Move

Howmet makes jet-engine parts. It reports Oct. 29 before the open, with the Street looking for earnings of $1.37 per share on revenue of $2.59 billion.

Last quarter's reaction was a fade. On Aug. 6, shares opened 2.6% higher and then closed down 0.6%.

Analysts have trimmed their targets this month. RBC Capital cut its target to $300 and TD Cowen cut to $280, though both kept bullish ratings.

Investors will watch engine-part demand, pricing and any update on the turbine-blade supply chain.

Howmet Aerospace Inc. (NYSE:HWM) shares are down 9% in 2026, one of the few names on this list trading in the red for the year.

10. Amphenol: 10.24% Implied Move

Amphenol makes the connectors and cables that link servers inside AI data centers. It reports Oct. 28 before the open.

Consensus calls for earnings of 72 cents per share on revenue of $9.46 billion.

Unlike most of the AI hardware group, Amphenol has kept the sell side on board. Goldman Sachs raised its target to $116 and Citigroup to $112 earlier this month, and Evercore ISI moved to $100.

Shares rose 4.5% after the second-quarter report on July 29.

Investors will look at IT datacom orders, the book-to-bill ratio and the fourth-quarter outlook.

Amphenol Corp. (NYSE:APH) has delivered a more modest 10.1% advance so far this year.

9. Corning: 10.41% Implied Move

The glass maker has turned into an AI fiber company. In September, Corning signed a $3 billion agreement to supply fiber and cable to AT&T.

Corning reports Oct. 27 before the open. Analysts model earnings of 88 cents per share on revenue of $5.03 billion.

The July report hurt. Shares fell 12.1% on July 28, and JPMorgan cut its target to $165 at Neutral last week.

Investors will watch optical communications sales, margins and whether hyperscaler orders are holding up.

Corning Inc. (NYSE:GLW) stock has rallied 43.1% in 2026.

8. Honeywell Aerospace: 10.73% Implied Move

This is only Honeywell Aerospace's second quarterly report as a standalone company, and the first one was painful.

On Aug. 6, after its second-quarter results, the stock dropped 23.2%. Management said the supply base had not ramped as expected, and the CEO said: "I underestimated how long it would take to implement and see traction from the corrective measures we had taken."

The company reports Oct. 28 after the close. The Street expects earnings of $1.87 per share on revenue of $4.57 billion, against full-year guidance of $7.60 to $7.90 per share.

Goldman Sachs started coverage at Neutral with a $190 target on Oct. 7, and RBC Capital lowered its target to $210 on Oct. 15.

Honeywell Aerospace Inc. (NASDAQ:HONA) shares are down about 17% from the $200 opening price of their June 15 trading debut.

7. Fortinet: 11.04% Implied Move

Fortinet is one of the year's best performers, and Wall Street is split on it.

The cybersecurity company reports Oct. 28 after the close. Analysts expect earnings of 86 cents per share on revenue of $2.06 billion.

Several targets now sit below the share price. JPMorgan raised its target to $140 last week but kept an Underweight rating, and Mizuho and Wells Fargo both hold bearish ratings with $160 targets. On the other side, Truist sees $200 and TD Cowen sees $225.

The last report was a fade as well. On July 30, shares opened about 7% higher and closed up only 0.7%.

Fortinet Inc. (NASDAQ:FTNT) shares have more than doubled this year, climbing 123.9%.

6. Vertiv: 11.74% Implied Move

Vertiv keeps AI servers cool, and the stock has been running hot and cold.

The data center equipment maker fell for 11 straight sessions through Oct. 20. On Oct. 21, Vertiv and Nvidia announced a faster approach to building AI factories.

Vertiv reports Oct. 28 before the open. Consensus calls for earnings of $1.83 per share on revenue of $3.76 billion.

The last report on July 29 sent the stock down 17.26%, exactly the size of the gain Quanta Services posted a day later.

Mizuho cut its target to $280 while keeping Outperform, and GLJ Research holds a Sell rating with a $188 target.

Vertiv Holdings Co. (NYSE:VRT) has added 20.9% since the start of 2026.

5. Carvana: 11.87% Implied Move

Carvana is the one name on the list with no ties to the AI trade, and its swings are a familiar feature of earnings week.

The online used-car retailer reports Oct. 28 after the close. Analysts expect earnings of 44 cents per share on revenue of $7.68 billion.

After the second-quarter report, the stock opened about 11% lower on July 30 and closed down 7.4%.

Wells Fargo lowered its target to $75 on Friday, and Morgan Stanley cut to $88 last week. Both kept Overweight ratings.

Carvana Co. (NYSE:CVNA) stock has shed 31.4% this year, losing nearly a third of its value.

4. Quanta Services: 12.05% Implied Move

Quanta builds the power lines and grid connections that AI data centers need.

It reports Oct. 29 before the open. The Street expects earnings of $4.98 per share on revenue of $10.97 billion.

Last quarter's results sent shares up 17.3% on July 30, one of the strongest earnings reactions on this list.

Bernstein upgraded the stock to Outperform with a $775 target in September.

Investors will watch the backlog, data center power projects and the 2027 outlook.

Quanta Services Inc. (NYSE:PWR) shares have advanced 30.9% year to date.

3. Robinhood: 12.28% Implied Move

Robinhood reports Oct. 27 after the close, giving the market an early read on retail risk appetite.

Analysts expect earnings of 56 cents per share on revenue of $1.42 billion.

Robinhood traders recently went on their biggest buying spree on record, according to an Oct. 1 report. Prediction markets are another storyline. A House investigation into insider trading on those platforms widened in late September.

Wall Street is mostly bullish. Rosenblatt started at Buy with a $135 target last week, and Needham raised its target to $126.

The stock fell 3.6% after the July report.

Robinhood Markets Inc. (NASDAQ:HOOD) has slipped 14.9% so far in 2026.

2. Intel: 12.98% Implied Move

Intel has more than doubled this year. The options market now prices a nearly 13% swing in either direction.

The chipmaker reports Oct. 29 after the close. Consensus calls for earnings of 39 cents per share on revenue of $16.45 billion.

The July report disappointed. Shares fell 7.9% on July 24.

The sell side remains cautious. JPMorgan upgraded the stock to Neutral with an $85 target on Oct. 19, while Susquehanna cut its target to $105 and TD Cowen to $95.

Investors will look at foundry progress, data center CPU demand and the gross-margin outlook.

Intel Corp. (NASDAQ:INTC) stock has surged 136% this year.

1. Monolithic Power Systems: 13.76% Implied Move

No stock with a market cap above $50 billion carries a bigger expected swing this week.

Monolithic Power makes the power-management chips that feed AI accelerators. It reports Oct. 29 after the close.

Analysts expect earnings of $7.75 per share on revenue of $1.14 billion.

The last reaction shows how wide the range can be. On July 31, the stock traded as much as 19% higher during the session but closed up 8.3%.

Ahead of the report, Wells Fargo cut its target to $1,550 and TD Cowen to $1,700, both keeping bullish ratings.

Monolithic Power Systems Inc. (NASDAQ:MPWR) shares are 27.6% higher since January.
