U.S. stocks went nowhere on Wednesday, October 28, 2026, as gains in chipmakers offset weakness in megacap names including Tesla and Apple, Reuters reported in its market wrap. The S&P 500 stood at 7,739.58, up 16.89 points or 0.22%. The Nasdaq Composite sat at 26,482.16, up a mere 4.35 points or 0.02%.
The Dow Jones Industrial Average was up 0.3% at the time of the Reuters report. Chip stocks led the tape after SK Hynix posted what Reuters called “bumper results.” Three scheduled events hung over everything else: a Federal Reserve rate decision later in the day, plus quarterly results from Microsoft and Alphabet after the closing bell.
This analysis looks at the session through a hardware lens. Memory demand, AI accelerators and data-center spending explain why chips rose while the biggest consumer-facing stocks sagged. For the pre-market setup, see our earlier note on how futures traded ahead of the Fed and Big Tech reports.

Wall Street Treads Water: What the Tape Showed
Flat indexes can hide a lot of movement underneath. On October 28 the pattern was clear. Semiconductor names rose, and a handful of the market’s heaviest weights fell. The two forces roughly canceled out at the index level.
The arithmetic backs that up. Subtract the reported point gains and the S&P 500’s prior level works out to about 7,722.69, while the Nasdaq Composite’s works out to about 26,477.81. The S&P gained 0.22% while the Nasdaq, which carries a heavier technology weighting, gained just 0.02%. That gap fits the Reuters description of megacap weakness holding back the tech-heavy index.
| Index | Level | Move | Percent |
|---|---|---|---|
| S&P 500 | 7,739.58 | +16.89 points | +0.22% |
| Nasdaq Composite | 26,482.16 | +4.35 points | +0.02% |
| Dow Jones Industrial Average | Not stated in report | Not stated in report | +0.3% (at time of Reuters report) |

SK Hynix Gives Chip Stocks Their Lift
The South Korean memory maker was the spark. Reuters said SK Hynix’s quarterly profit jumped, and chip stocks rose in response. The available report does not state the exact profit figure, and the numbers floating around other outlets did not clear our verification. We leave them out.
What matters is the direction. Memory has become one of the tightest links in the AI hardware chain. Every data-center accelerator needs high-bandwidth memory stacked next to the processor, and a memory supplier reporting a sharp profit jump tells investors that buyers are still writing big checks. Traders read the results as fresh evidence that AI infrastructure spending has not cooled.
Memory stocks have been a steady theme in our coverage. Our look at Micron’s Zacks Rank #1 rating and surging earnings estimates showed the same dynamic on the U.S. side. SK Hynix extends the story to Asia, where the world’s largest memory makers compete for the same AI orders.
Why Megacap Weakness Capped the Index Gains
Tesla and Apple drew the most attention on the downside. Reuters tied the weakness in megacap stocks, including those two, to the flat finish for the major indexes. The fact sheet for this story does not include percentage moves for either stock, so we skip them.
Pre-event positioning is the likeliest explanation, though no outlet confirmed it as the cause. Large holders often trim crowded positions before a Fed decision and a pair of earnings reports. That tends to hit the biggest, most widely held names first because they are the easiest to sell.
Apple’s relative position matters this week. We covered how Apple briefly topped Nvidia as the most valuable company intraday before giving up the lead at the close. A soft Apple session on October 28 fits a market that keeps rotating between consumer hardware and AI silicon.
The Fed Decision Looms Over a Quiet Session
The Federal Reserve scheduled its interest-rate decision for later on October 28. The session read as a holding pattern, and the small index moves are consistent with traders waiting for the announcement.
A caveat on timing: some live blogs, including Yahoo Finance’s rolling coverage, keep updating through the afternoon, so their headlines may carry later developments. This article reflects the pre-decision snapshot in the Reuters wrap. It does not state the outcome of the Fed meeting, because the available report does not confirm it.
Why should hardware readers care? Rate expectations feed directly into the valuation of capital-hungry sectors. Semiconductor makers and the data-center builders who buy their chips borrow heavily to fund fabs, servers and power. A shift in the rate path changes the cost of that spending, which in turn changes the order books at memory and chip suppliers.
Microsoft and Alphabet: Cloud Growth Under the Microscope
Microsoft and Alphabet were both scheduled to report after the market closed on October 28. Reuters said investors expected both to show accelerating cloud growth. The Admiral Markets earnings calendar for the week lists the Fed decision and Big Tech reports as the main events.
Cloud numbers matter to chipmakers because the hyperscalers buy the accelerators and memory that SK Hynix and its rivals sell. If cloud growth accelerates, the capacity race continues. If it slows, the AI hardware trade faces harder questions. We examined that setup in our piece on the AI boom’s earnings test, with its $1.7 trillion backlog and $600 billion spending figures.
The final results were not available when this article was prepared. Exact figures for Microsoft’s and Alphabet’s quarters, and for the market’s reaction, remain unconfirmed here.
Memory Is the Hardware Story Inside the AI Trade
Most market coverage treats chips as one block. Inside that block, memory and processors behave differently. Processor designers capture headlines, but memory suppliers decide how many accelerators can actually ship, because each one needs stacked memory to run at full speed.
High-bandwidth memory as the bottleneck
Reuters did not name a new memory product in its report, and neither did the SK Hynix coverage we could verify. The reporting described demand for the product category rather than a launch. We therefore make no claims about specific generations or capacities.
Foundry and packaging constraints
Advanced packaging sits next to memory as a chokepoint. We reported on TSMC weighing a 20% price increase for CoWoS packaging used in Nvidia chips, a report that points the same way as the SK Hynix news. When suppliers across the chain can raise prices or post big profit jumps, buyers are competing for scarce capacity.
What Gartner and IDC Numbers Say About Semiconductor Demand
Market-wrap headlines offer one day of data. Industry research gives the wider backdrop. Gartner’s preliminary 2025 results put the scale of the business in perspective. In its January 2026 release, Gartner stated that “Worldwide semiconductor revenue totaled $793 billion in 2025, an increase of 21% year over year.”
The same Gartner release explained where the growth came from. It said, “AI semiconductors, including processors, high-bandwidth memory, and networking components, accounted for nearly one-third of total semiconductor sales in 2025.” That one-third share is why a single memory earnings report can move an entire sector.
IDC takes a more aggressive view of 2026. Its forecast reads, “IDC forecasts total semiconductor revenue of $1.29 trillion in 2026, up 52.8% year over year from $842.8 billion in 2025.” Note that IDC’s 2025 baseline of $842.8 billion differs from Gartner’s $793 billion. The two firms define and count the market differently, and we have not reconciled the gap.
IDC also flagged the supply side in a separate analysis. It wrote that “IDC forecasts supply growth of 16% for DRAM and 17% for NAND in 2026.” Supply growing in the mid-teens while demand surges is the setup that lifts memory profits.
Chips vs Megacaps: A Side-by-Side Comparison
The table below lines up the two camps that pulled the market in opposite directions on October 28. It uses only what the Reuters wrap and the fact sheet confirm.
| Factor | Chipmakers | Megacaps (Tesla, Apple) |
|---|---|---|
| Session direction | Rose | Fell |
| Named catalyst | SK Hynix quarterly results | None named by Reuters |
| Tie to AI spending | Direct (memory, accelerators) | Indirect |
| Event risk tonight | Microsoft and Alphabet cloud demand | Fed decision and broader tech earnings |
| Exact percentage moves | Unconfirmed in available report | Unconfirmed in available report |
The split shows a market that rewards companies with a clear line to AI infrastructure demand. Consumer-facing megacaps lack that direct link, so they traded on positioning instead.
Historical Context: Event-Day Sessions Rarely Trend
Sessions that combine a Fed decision with major earnings tend to produce muted index moves until the news lands. Traders hold fire, and volume often thins. October 28 followed that script, with the S&P 500 up 0.22% and the Nasdaq barely changed.
What set this session apart was the sector split. Memory has moved from a cyclical afterthought to a growth story. Gartner’s figure of $793 billion in 2025 chip revenue, with AI parts accounting for nearly a third, shows how much weight the category now carries. Memory results now carry enough weight to steady the broader chip group on an otherwise flat day.
Why One Memory Report Can Steady a Whole Sector
Investors rarely treat SK Hynix as a standalone story. They treat it as a read-through for every company that depends on AI hardware demand. A strong memory quarter suggests accelerator makers, server builders and packaging suppliers are all still shipping into healthy order books.
That read-through explains why chip stocks rose broadly instead of just one Korean ticker. It also explains the timing. With two of the largest cloud operators reporting that same evening, traders used the SK Hynix numbers as an early check on the thesis before the hyperscalers spoke.
The risk runs the other way too. Because so much sentiment rides on a few reports, a weak cloud quarter or a cautious spending outlook could undo the gains quickly. Chip stocks that rise on a read-through can fall on one as well. That asymmetry makes caution into the close unsurprising, and it means the index-level calm on October 28 may not last.
For readers who build or buy hardware, the lesson is to separate the stock story from the product story. Share prices can swing on a single evening. Memory contracts, fab capacity and packaging queues move over quarters, and those slower forces set what you pay for a server or an SSD.
Market Impact for Hardware Buyers and Builders
Strong memory earnings do not stay on Wall Street. They tend to show up as higher prices for the parts that go into servers, PCs and storage devices. IDC’s supply forecast of 16% growth for DRAM and 17% for NAND suggests suppliers have limited room to flood the market.
Storage buyers already feel it. Our coverage of enterprise SSD prices forecast to rise 23% to 28% in the fourth quarter shows how memory tightness reaches procurement budgets. Readers planning upgrades can follow more of this in our hardware section.
For IT teams, the practical advice is simple. Lock in quotes for server memory and flash storage earlier than usual, and expect suppliers to resist long price holds. Consumers face a milder version of the same squeeze, mostly through higher prices on high-capacity SSDs and RAM kits.
What Is Still Unconfirmed
Fast-moving market stories attract loose numbers. The table below separates what the available reporting confirms from what it does not.
| Item | Status | Detail |
|---|---|---|
| S&P 500 at 7,739.58 (+0.22%) | Confirmed | Reuters market wrap |
| Nasdaq Composite at 26,482.16 (+0.02%) | Confirmed | Reuters market wrap |
| Dow up 0.3% | Confirmed (timing-specific) | As of the Reuters report |
| SK Hynix profit jump | Confirmed (direction only) | Exact figure not stated |
| Fed decision outcome | Unconfirmed here | Decision scheduled later on Oct. 28 |
| Microsoft and Alphabet results | Unconfirmed here | Reported after the close |
| Chipmaker percentage gains | Unconfirmed here | Not in the available report |
| Executive quotes on the session | None available | No on-record quotes in the report |
Other outlets published specific profit, revenue and rate figures for the day. We did not use them, because the verified record available for this story does not back them. Readers who need the final numbers should check the primary releases from SK Hynix, the Federal Reserve, Microsoft and Alphabet.
Five Predictions for the Next Sessions
These are our judgments, not reported facts. Each could be wrong.
- Index volatility returns once the news lands. A flat tape before three major events usually gives way to bigger moves after them. We expect Thursday’s open to carry more movement than Wednesday’s session did.
- Cloud commentary will steer chip stocks. If Microsoft and Alphabet describe accelerating cloud demand, memory and accelerator names should hold their gains. A cautious tone would test them.
- Memory remains the leadership group. With IDC projecting supply growth of 16% for DRAM and 17% for NAND, we expect memory pricing to stay firm through the end of the year.
- Megacap weakness proves short-lived or it spreads. One soft session for Tesla and Apple means little. A second and third would signal a real rotation toward AI hardware.
- Hardware prices keep climbing for buyers. SSD and server memory costs should stay elevated into the new year, in line with the forecasts we cited earlier.
How to Read the Evening Results
Three checks help separate signal from noise once the numbers arrive. First, compare cloud growth rates against what analysts expected, since Reuters said both companies were projected to show acceleration. A beat that merely matches a high bar can still disappoint.
Second, listen for capital-spending language. Any change in how much the hyperscalers plan to spend on servers and chips flows straight to memory and accelerator suppliers. Third, watch how the Fed’s statement reads against the market’s rate expectations, because chip valuations lean heavily on the cost of capital.
If you track hardware stocks, keep a short list of reference points: SK Hynix’s own commentary, the memory outlook in the hyperscalers’ remarks, and any follow-through in Bloomberg’s live market updates on the next trading day.
Frequently Asked Questions
How did the S&P 500 and Nasdaq finish on October 28, 2026?
Reuters reported the S&P 500 at 7,739.58, up 16.89 points or 0.22%, and the Nasdaq Composite at 26,482.16, up 4.35 points or 0.02%. Those figures come from the market wrap, which described choppy trading.
Why did chip stocks rise?
Reuters linked the gains to SK Hynix’s results, which it described as bumper. The company’s quarterly profit jumped, reinforcing the view that AI-driven memory demand remains strong. The available report does not give the exact profit number.
Which megacap stocks fell?
Reuters named Tesla and Apple among the megacaps whose weakness offset the chipmakers’ gains. The report we verified does not list exact percentage moves for either.
When did the Fed announce its decision?
The Federal Reserve scheduled its rate decision for later on October 28, 2026. This article does not state the outcome because the available report does not confirm it.
When did Microsoft and Alphabet report?
Both companies were scheduled to report quarterly results after markets closed on October 28. Reuters said investors expected accelerating cloud growth from each.
What does the SK Hynix result mean for PC and server buyers?
Strong memory earnings point to tight supply and firm pricing. IDC forecasts supply growth of 16% for DRAM and 17% for NAND in 2026, which leaves limited room for price cuts. Expect high-capacity SSDs and server memory to stay costly.
