Wednesday is the day this week was built around: the Fed decides at 2 p.m. ET — a hold at 3.75% to 4.00% is expected with roughly 90% probability, with Chair Kevin Warsh’s 2:30 p.m. press conference the real event — and Microsoft and Alphabet report after the close, with consensus at about $4.72 a share on $90.6 billion for Microsoft and about $3.02 to $3.03 a share on about $128 billion for Alphabet. But the freshest money this morning is not in the previews. It is in results already printed: a memory blowout out of Korea, an Investor Day for a beaten-down AI cloud name, a fintech that just raised its guide, and a storage stock teaching the week’s hardest lesson — in this market, a beat is only the entry ticket.

1. SK Hynix (SKHY) — an 80% operating margin, and memory is the AI trade now

SK Hynix reported third-quarter results on Wednesday in Korea and they were not close. Revenue hit 104.62 trillion won — over 100 trillion won in a single quarter for the first time — up 327.9% from a year earlier and 31.9% from the prior quarter. Operating profit reached 83.33 trillion won, up 632.1% year over year, for a staggering 79.7% operating margin. Both lines cleared the FnGuide consensus of 76.96 trillion won in operating profit on 98.23 trillion won in revenue.

The driver is high-bandwidth memory, the stacked memory that feeds Nvidia’s AI accelerators. SK Hynix commands more than half the global HBM market, said HBM4 shipments are ramping, and expects HBM4 to overtake HBM3E in both volume and revenue in the fourth quarter. It has secured long-term supply agreements with 14 major customers covering more than half of its planned production capacity for 2027 and 2028, and it forecast memory supply shortages lasting through 2030. The cash is being returned: a 2026 shareholder-return program of about 100 trillion won, including at least 30 trillion won in dividends and at least 60 trillion won in buybacks, with a third-quarter dividend of 20,000 won a share — half of it a special dividend tied to its Kioxia investment gains. In Seoul the stock rose about 9.9%, Samsung rose about 9%, and U.S.-listed SK Hynix shares pointed up 8.5% premarket, with Micron up 4.5% and the Roundhill Memory ETF up 5.5% in sympathy.

What to watch: Whether the U.S. listing holds the premarket gain once Microsoft and Alphabet capex commentary lands tonight — hyperscaler spending plans are the demand side of SK Hynix’s order book — and whether HBM4 mix keeps the margin near these levels next quarter.

Caution flag: An 80% operating margin is a peak-cycle number by definition. Memory is historically the most cyclical corner of semiconductors, and a stock that has just printed +328% revenue growth is priced for the shortage story to keep delivering.

2. Oracle (ORCL) — Investor Day today, with the stock 60% below its record

Oracle holds its Investor Day meeting today, Wednesday, October 28, at 10:55 a.m. Central Time during Oracle AI World in Las Vegas — and it is a genuine test, not a victory lap. The stock closed Tuesday at $130.53, up 3.5% on the day, but that is roughly 60% below the $328.33 record close set in September 2025 and well below the $313 close on the day of its last investor meeting in October 2025, when management targeted $225 billion of revenue in fiscal 2030.

The bull case walking into today is the backlog. Oracle’s latest quarter showed revenue up 30%, cloud revenue up 62%, cloud infrastructure revenue up 121%, and remaining performance obligations rising to $664 billion. Wall Street leaned in ahead of the event: Bernstein reiterated an Outperform rating with a $325 price target on October 27, and Barclays reiterated Overweight with a $252 target on October 26, both pointing to faster cloud infrastructure growth and better funding visibility. Oracle has also kept the deal flow coming at AI World, expanding AI chip partnerships and announcing a $1 billion partner-ecosystem commitment over the next four years on October 23.

What to watch: Any update to long-term revenue and earnings targets, the funding plan for the data-center build — borrowings had grown about 37% over the year through August 31 to about $125 billion — and plain language on capacity, margins, and cash flow, which is where today’s questions are sharpest.

Caution flag: The last Investor Day’s targets did not protect the stock — it fell about 7% the next day and kept falling. A big backlog only converts to value if the build to serve it does not consume the cash flow it promises.

3. SoFi Technologies (SOFI) — record members, a raised guide, and a 2027 number above the Street

SoFi delivered the cleanest consumer-finance print of the week on Tuesday. Third-quarter adjusted earnings were $0.18 a share against $0.17 expected, adjusted net revenue rose 44% to a record $1.37 billion against about $1.25 billion to $1.26 billion expected, and net income was $241.0 million. The company added a record 1.2 million members to reach 17.07 million, with total members up 35% year over year.

What moved the stock — up about 13% to 15% on Tuesday for its best day of the quarter — was the guide. SoFi raised its 2026 adjusted net revenue outlook to about $5.04 billion, with about $0.61 of earnings a share expected for 2026, and then looked further out: about $6.4 billion of revenue and about $0.90 of adjusted earnings a share for 2027, above the roughly $0.82 consensus for that year. Loan originations jumped 71% in the quarter, per the company’s release coverage.

What to watch: Whether member growth keeps converting to products per member — 1.56 in the quarter, up from 1.47 a year ago — and whether credit quality holds as originations grow that fast into a 3.75% to 4.00% policy rate.

Caution flag: SoFi shares were still down sharply year to date even after Tuesday’s surge. One raised guide re-rates a fintech only if the next two quarters confirm it — the 2027 outlook is now the number to defend.

4. Seagate Technology (STX) — beat, raised, and sold anyway: the scorecard lesson

Seagate is the cautionary tale inside an otherwise strong week, and it belongs in this post because it answers the question traders asked before the print: what happens when options price a double-digit move for a stock already up about 150% this year? Seagate reported fiscal first-quarter earnings on Tuesday night of $7.68 a share, beating consensus of about $7.42 to $7.45, on revenue of $4.23 billion, up 61.0% year over year and ahead of the $4.14 billion to $4.15 billion expected. Its current-quarter forecast also came in ahead of Street projections, helped by strong AI storage demand.

The stock fell anyway — down about 2.5% in Wednesday premarket trading after a larger after-hours drop Tuesday night. Robinhood told the same story in miniature the same night: $0.60 a share on $1.42 billion of revenue, with agentic AI trading accounts more than doubling to about 200,000 customers and over $1.6 billion in volume, but crypto revenue plunged, expenses climbed, and the shares fell about 6% premarket. Two beats, two selloffs.

What to watch: Whether Seagate stabilizes once the post-print positioning clears — the fundamentals in the release, AI-driven hard-drive demand and a higher guide, did not get worse on Tuesday night — and how Microsoft and Alphabet trade tonight if they follow the same beat-and-fade pattern.

Caution flag: This is the high-bar problem in its purest form. When a stock is up roughly 150% year to date into its print, investors are not buying the quarter that just happened; they are underwriting the next four. Anything short of a blowout can read as a disappointment.

The bottom line: The AI infrastructure stack keeps sorting itself into who collects the cash and who carries the bill. Today SK Hynix collected — record revenue, an 80% margin, and a huge return of capital — while Oracle has to convince investors at 10:55 a.m. CT that its $664 billion backlog will convert without drowning the balance sheet. SoFi showed a consumer business can still raise a two-year outlook in a high-rate world, and Seagate and Robinhood showed the penalty for merely beating when the run into the print was the real story. Tonight’s Microsoft and Alphabet reports, hours after the Fed, will decide which of those two lessons — collect, or carry — defines the rest of the week. Amazon, Eli Lilly, Visa follow-through, and Intel follow on Thursday, with Exxon Mobil on Friday and Apple and Palantir on Monday, November 2.
