Market Snapshot October 20th 2026

The Rotation Reversed Within One Session as Yields Rose — the Equal-Weighted S&P Fell While the Cap-Weighted Index Gained, and Oracle’s Bonds Sit “Dangerously Close to Junk”

Data:

Main Theme: “One Week, One Session” — The 10-year rose 6 basis points to 5.15% and every sector that rallied on last week’s yield decline reversed: utilities fell 2.01%, real estate 1.16%, financials 0.83%. Technology rose 1.36% and the semiconductor index 1.61%, ending an eight-session streak. The equal-weighted S&P fell 0.32% while the cap-weighted index rose 0.41%.

The previous edition posed the question directly: “The rotation lives or dies on whether yields stay down.” The answer arrived in a single session.

Yields rose across the curve. The 2-year gained 3 basis points to 4.77%, the 10-year 6 basis points to 5.15%, and the 30-year 5 basis points to 5.48%. The 2s10s spread steepened to about 38 basis points from 35.

Every bond proxy that recovered last week gave it back.

Sector Monday Last week
Utilities −2.01% +1.10% Friday
Real estate −1.16% Recovered on falling yields
Financials −0.83% +1.03% Friday
Healthcare −0.60% Record high Thursday
Technology +1.36% −3.00% Friday
Consumer discretionary +1.78% −0.84% Friday

 

The index outcome concealed it. The S&P 500 rose 0.41% to 7,690.73 and the Nasdaq Composite 1.11% to 26,430.89, while the Dow Jones Industrial Average fell 0.07% to 51,966.03 and the Russell 2000 managed only +0.25% to 2,728.30.

But the breadth was negative. NYSE decliners beat advancers 1,761 to 945, and the equal-weight S&P 500 ETF fell 0.32% while the cap-weighted index rose 0.41%.

That is the precise inverse of 8 October, when the equal-weight index rose 0.60% against a cap-weighted decline of 0.47% — and the inverse of the week that produced the best equal-weighted performance against technology since 2009.

The Philadelphia Semiconductor Index rose 1.61% to 11,316.34, ending an eight-session losing streak that was its longest since 2006.

CappNotes described it accurately: a relief bounce concentrated in AI and chips rather than a broad recovery, since most stocks and the equal-weight index fell.

The analytical content is in the mechanism rather than the magnitude. Last week’s historic rotation was triggered by the 10-year falling 14.6 basis points — the largest weekly decline since 13 February. This publication argued it had “a mechanical cause rather than a sentimental one” and depended entirely on yields staying down.

Yields rose 6 basis points and the rotation reversed in full. That is as clean a confirmation of the framework as the market is likely to provide.

The implication is uncomfortable for anyone positioning on the broadening thesis: the concentration is not a sentiment phenomenon that can correct on its own. It is a rate phenomenon, and it reverses whenever the 10-year moves back toward 5.3%.

🔻 Oracle’s Bonds and the Credit Channel

Sources: CNBC via CappNotes / TheStreet

Oracle rose 1.06% on the day, even as CNBC reported its bonds sit “dangerously close to junk.” TheStreet separately carried a headline reading “CoreWeave, Oracle have an interest rate problem.”

This is a material escalation, and it should be stated carefully because the phrase is a characterisation rather than a rating action.

The leverage question raised on 14 October has until now been an equity-market concern: CoreWeave fell more than 16% intraday that day and more than 15% over last week on its $50 billion debt load, and Oracle fell about 9% on 14 October and 5.58% on 8 October.

Bonds trading near junk levels moves the question into credit, which matters for three reasons.

The investor base is different. Investment-grade mandates are constrained by rating; a downgrade below investment grade forces selling regardless of view. Equity holders can choose to ride out a drawdown.

The financing cost compounds. This publication has documented roughly $600 billion of AI buildout borrowing since last year, more than $150 billion of it hyperscaler dollar investment-grade debt. Spread widening raises the cost of refinancing all of it, not just the issuer in question.

And the timing is adverse. CME FedWatch showed an 89% probability of a December rate hike as of Friday. Credit deterioration into a tightening cycle is the configuration that turns a leverage question into a funding problem.

The qualification is that Oracle is an established investment-grade issuer with substantial operating cash flow, and a bond trading near a threshold is not the same as crossing it. No rating action was reported.

🛠️ Amazon Challenges CUDA

Sources: CappNotes / TheStreet

Amazon rose about 4.95% to 4.98% — the largest move among megacap technology — after releasing TorchNeuron, a free tool to run PyTorch on its Trainium chips, which CappNotes characterises as a challenge to CUDA. Morgan Stanley separately named Amazon a top pick with a $350 target, citing AWS growth and Bedrock.

The CUDA framing deserves attention because it addresses the deepest part of Nvidia’s competitive position.

Nvidia’s moat has never been primarily silicon. It is the software layer — CUDA — that makes its hardware the default target for machine learning development. A free tool that lets PyTorch, the dominant framework, run on a competitor’s silicon attacks the switching cost rather than the performance gap.

It also fits a pattern that has developed over eight days. On 12–13 October ChangXin Memory Technologies was reported advancing toward a server-memory product, challenging the memory oligopoly. Monday adds a challenge to the software layer from a hyperscaler that is simultaneously one of Nvidia’s largest customers.

Nvidia nonetheless rose 1.38% and AMD 1.76% in the broader chip recovery, so the market did not read this as an immediate threat — and the honest position is that CUDA displacement has been predicted repeatedly for a decade without materialising.

Companies

Theme: “A Goldman Upgrade That Did Not Hold” — CoreWeave gave up early gains to close down 0.44% despite an upgrade to Buy. Memory names rebounded hard with Western Digital up 6.09%. Cleveland-Cliffs rose 16.34% and guided 2027 EBITDA above $4 billion. Cerebras fell to a 52-week low.

Monday’s single-stock tape separated a genuine industrial beat from an AI bounce that several names could not hold.

⚠️ 1. CoreWeave Could Not Hold a Goldman Upgrade

CoreWeave received an upgrade to Buy from Goldman Sachs and gave up early gains to close down 0.44%.

That is the session’s most informative single-stock outcome, and it says more than the index move.

An upgrade from a bulge-bracket bank on a stock that fell more than 15% the previous week should produce a strong bounce, particularly on a day the Nasdaq rose 1.11% and the semiconductor index 1.61%. Memory names rose between 2.97% and 6.09%; the neoclouds bounced, with Applied Digital up 6.65%, Nebius 2.88% and IREN 2.74%.

CoreWeave did not participate. In a sector-wide relief rally, with an upgrade, it closed lower.

The reading is that the market is distinguishing between the AI trade and the AI leverage trade. CoreWeave’s $50 billion debt load is a specific, quantified obligation that a rating-agnostic equity upgrade does not address — and with the 10-year back at 5.15% and a December hike at 89% probability, the refinancing arithmetic worsened on the same day.

It also sits alongside the Oracle bond characterisation. Two of the most levered participants in the AI buildout failed to benefit from a session in which their sector rallied.

💾 2. Memory Rebounded Hardest From the Deepest Hole

Western Digital rose 6.09%, SanDisk 5.53% and Micron 2.97%, leading the semiconductor recovery.

TheStreet noted SanDisk rose over 5.5% after falling more than 22% over the past month — which is the right context for all three.

Date Event Memory reaction
12 Oct CXMT architecture reports SOX −2.7% at the low
13 Oct CXMT server-memory product by year-end Kospi −5.46%; Micron −4.6%
15 Oct Memory ETF among the worst SOX seventh straight decline
16 Oct Memory ETF −5.5% SOX eighth decline — longest since 2006
19 Oct Rebound WDC +6.09%; SanDisk +5.53%; Micron +2.97%

 

A 22% decline in a month followed by a 5.5% bounce is a technical recovery, not a resolution. The CXMT question — whether a Chinese competitor reaches a server-memory product by year-end — is unchanged by a single session.

TheStreet also attributed part of the chip bounce to an Nvidia announcement on memory and technology standardisation, which this publication has not been able to verify in detail and which should be treated as reported rather than established.

The instrument that matters remains Micron’s December report, which falls after CXMT’s stated deadline — and specifically its pricing commentary rather than its revenue line.

🏭 3. Cleveland-Cliffs Delivered the Session’s Real Beat

Cleveland-Cliffs rose 16.34% after adjusted earnings of $0.28 per share beat a $0.21 estimate, and guided to 2027 adjusted EBITDA above $4 billion.

A 16% move on a 33% earnings beat with forward guidance attached is the clearest illustration this season of what the market is actually paying for.

The contrast with technology is instructive. TSMC posted a sixth consecutive record profit with fourth-quarter guidance about 5.6% above consensus and fell 4.14%. Micron nearly quadrupled revenue, beat guidance by roughly 8% on both lines, and slipped. Morgan Stanley beat on both lines on 14 October and fell nearly 4%.

Cleveland-Cliffs beat by a third and rose 16%.

The difference is expectation. Technology carried elevated expectations into the season and is being audited on cost structure and outlook; steel carried low expectations and delivered a quantified multi-year target. Daniela Hathorn’s observation that investors are “increasingly focused on forward guidance rather than headline earnings beats” applies in both directions — the forward guide is what paid here too.

JPMorgan’s Jay Horine supplied a complementary framing: “In the next leg we are going to be focusing on expanding industrial capacity.”

📋 4. The Rest of the Tape

Bill Owens of the National Association of Home Builders captured the housing position: “Builders are also contending with higher costs for construction loans, building materials and diesel.” That is the margin-absorption story in a single sentence, from a sector facing all three cost channels this publication has tracked.

And Brian Moynihan of Bank of America addressed the $1.2 billion regulatory penalty disclosed on 14 October: “We’ve built up the resources and are deep into remediation activities.”

General

Monday, October 19th, 2026: Six Basis Points Undid a Seventeen-Year Record

The 10-year Treasury yield rose 6 basis points to 5.15% and every sector that rallied on last week’s decline reversed. Utilities fell 2.01%, real estate 1.16%, financials 0.83% and healthcare 0.60%, while technology rose 1.36%.

The equal-weighted S&P fell 0.32% while the cap-weighted index rose 0.41%, and NYSE decliners beat advancers 1,761 to 945.

  1. The Framework Was Tested and Held

The previous edition made a specific, falsifiable claim about last week’s historic rotation: that it had “a mechanical cause rather than a sentimental one,” that the trigger was a 14.6 basis point weekly fall in the 10-year, and that it “lives or dies on whether yields stay down.”

Monday tested that in the most direct way available. Yields rose 6 basis points and the rotation reversed in full within one session.

Sector Last week (falling yields) Monday (rising yields)
Utilities +1.10% Friday −2.01%
Healthcare Record high Thursday −0.60%
Financials +1.03% Friday −0.83%
Real estate Recovered −1.16%
Technology −3.00% Friday; −4.48% weekly +1.36%
Equal-weight vs cap-weight Best week vs Tech since 2009 −0.32% vs +0.41%

 

Every line reversed. That is not a partial confirmation.

The implication is the important part, and it is unwelcome for anyone who read last week as a structural broadening.

The concentration in this market is a rate phenomenon. It is not investors chasing a theme, and it is not a valuation bubble — technology trades at roughly 21 times forward earnings against 32 last October, Nvidia below the index multiple, Micron near 6.8 times. It is capital occupying the only part of the market where a 5%-plus risk-free rate does limited damage, because net-cash companies with growing earnings are genuinely less rate-exposed than leveraged small caps and bond proxies.

Melissa Brown of SimCorp observed on Friday that a theme at 40% of market weight “has often been associated with a market peak,” and said “the U.S. market is there now.” Monday suggests the concentration will not resolve through sentiment. It resolves when the risk-free rate falls durably — and the 10-year has now failed to break below 5% once while failing to hold above 5.3% three times.

  1. The Curve Steepened, Which Changes the Message

The 2-year rose 3 basis points to 4.77%, the 10-year 6 basis points to 5.15% and the 30-year 5 basis points to 5.48%. The 2s10s spread widened to about 38 basis points from 35.

That steepening matters because it inverts what the curve said last week.

On 14 October, after the hot CPI print, the 10-year spiked to 5.33% and reversed to about 5.2% while the 2-year rose — the curve flattened, and this publication read it as “a policy-induced slowdown being priced.” On 15 October the hot PPI print took long-dated yields down most, reinforcing it.

Monday reversed the shape. A steepening with long yields rising faster than short ones is term premium reasserting — the configuration that dominated from mid-August to early October, when the 10-year rose 115 basis points from 4.16% on fiscal supply and the buyers’ strike question.

The honest reading is that the market has not settled between two interpretations of the same data:

Both readings are available from the same prints, and the alternation between them is why the 10-year has oscillated between roughly 5.05% and 5.33% without resolving in either direction.

  1. The Leverage Question Entered the Credit Market

CNBC reported that Oracle’s bonds sit “dangerously close to junk,” and TheStreet carried a headline reading “CoreWeave, Oracle have an interest rate problem.” Oracle nonetheless rose 1.06%, while CoreWeave gave up a Goldman Sachs upgrade to close down 0.44%.

This is the fifth question asked of the AI complex since August, now migrating from equity into credit — and the migration is what makes it more serious rather than merely louder.

Three mechanisms distinguish a credit concern from an equity one.

Forced selling. Investment-grade mandates are constrained by rating rather than by view. A downgrade below investment grade produces selling regardless of what the holder thinks, which equity drawdowns do not.

Contagion through spreads. Roughly $600 billion of AI buildout borrowing has been documented here since last year, including more than $150 billion of hyperscaler dollar investment-grade debt and a record $135 billion of convertibles with just under half from AI. Spread widening at one large issuer raises the refinancing cost for all of it.

And the policy backdrop is adverse. CME FedWatch showed an 89% probability of a December hike as of Friday, and Monday added 6 basis points to the 10-year. Credit deterioration into tightening is how a leverage question becomes a funding problem.

The qualifications are real and should travel with the story. “Dangerously close to junk” is a characterisation, not a rating action; no downgrade was reported. Oracle is an established investment-grade issuer with substantial operating cash flow. And Oracle shares rose on the day, so the equity market did not treat it as acute.

But CoreWeave failing to hold a Goldman upgrade in a session where its sector rallied, with the neoclouds up between 2.74% and 6.65%, is the market distinguishing the AI trade from the AI leverage trade — and doing so deliberately.

  1. Amazon Attacked the Software Moat

Amazon rose about 4.98% after releasing TorchNeuron, a free tool to run PyTorch on its Trainium chips, characterised as a challenge to CUDA.

The significance is where it aims. Nvidia’s durable advantage has never been purely silicon — competitors have produced comparable raw performance before. The moat is CUDA, the software layer that makes Nvidia hardware the default target for machine learning development and imposes switching costs on anyone who moves.

A free tool enabling PyTorch — the dominant framework — to run on competing silicon attacks the switching cost directly rather than the performance gap.

It also completes an eight-day sequence in which three distinct layers of the AI stack were challenged:

Date Layer challenged By whom
12–13 Oct Memory CXMT — server-memory product by year-end
14–19 Oct Financing Credit markets — Oracle bonds, CoreWeave’s $50bn
19 Oct Software Amazon — TorchNeuron on Trainium

 

The appropriate caution is that CUDA displacement has been forecast repeatedly for a decade without occurring, and the market did not price this as acute: Nvidia rose 1.38% and AMD 1.76% in the same session.

What the sequence does establish is that the AI complex is now being questioned on three independent fronts simultaneously, where through most of this year it was questioned only on the discount rate.

  1. Oil at a Five-Week High With Hormuz Flows Falling

November WTI settled up 2.22% at $103.66, its highest settlement since 15 September. December Brent eased 0.28% to $109.55 and December WTI 0.48% to $98.54 — the divergence reflecting contract roll rather than a market split.

CappNotes attributed the move to supply fears persisting after Houthi attacks on Saudi energy sites and a sharp drop in Hormuz crude flows.

That second element continues the physical story this publication has weighted above diplomatic developments since 2 September. Crude exports through the Strait averaged 8.5 million barrels per day in the week to 12 October, nearly 40% below pre-war levels, with a vessel reported sunk on a naval mine on 14 October.

Two analyst framings from the session bear noting. Priyanka Sachdeva of Phillip Nova described an effort to increase supply as “another desperate attempt to keep oil prices in check,” and Tim Waterer of KCM Trade said “the market is unlikely to fully price in a sustained increase in supply.”

Both reflect the pattern documented here twelve times since February: political and supply announcements produce declines that reverse, while physical events produce moves that persist.

The energy sector nonetheless fell 0.64% on Monday — a bond-proxy-adjacent decline in a rising-yield session, after Exxon, EOG, ConocoPhillips, BP and Shell hit 52-week highs on 15 October.

Tuesday, October 20th, 2026 — Theme: “Netflix Opens the Technology Reports” — Netflix reports into a subscriber estimate cut of 25%, as the heaviest technology earnings week of the quarter begins with the FOMC eight days away and the 10-year back at 5.15%.

Tuesday starts the sequence that will decide whether last week’s rotation was broadening or de-rating. James DePorre of TheStreet Pro put it plainly: “The reaction to earnings reports will determine where things are headed.”

  1. Netflix Carries More Than Its Own Result

M Science cut its third-quarter subscriber estimate to 3.80 million from 5.10 million, below a 4.10 million consensus — a 25% reduction to the forecast, disclosed on 16 October.

Netflix matters beyond its own numbers for two reasons.

It sits in the weakest sector. Communication services fell 1.89% on 16 October and 0.21% on Monday, and has been among the consistent laggards. Wells Fargo downgraded Netflix on 18 September on AI disruption concerns.

And it is the first major technology report after a week in which the sector fell 4.48%. A reaction function established across the season has been unforgiving: TSMC posted a sixth consecutive record profit with guidance 5.6% above consensus and fell 4.14%; Micron nearly quadrupled revenue and slipped; Morgan Stanley beat both lines and fell nearly 4%.

The specific thing to watch is whether a reduced bar produces a different outcome. Cleveland-Cliffs rose 16.34% on Monday on a 33% beat because expectations were low. If Netflix clears a lowered estimate and still falls, the problem is positioning rather than results.

  1. The Rotation Question Is Now Daily

Monday established that the breadth signal flips with the 10-year. That makes the yield the instrument to watch rather than the index.

If the 10-year… Expect Evidence
Falls toward 5.00% Bond proxies and small caps lead; equal-weight outperforms Thursday–Friday last week
Rises toward 5.30% Technology leads; equal-weight underperforms Monday
Oscillates Alternating sessions with no trend The pattern since 7 October

 

The 10-year has now failed to break below 5% once and failed to hold above 5.3% three times, and the curve has alternated between flattening and steepening within four sessions. That is a market without a settled view, and it reflects two defensible interpretations of the same inflation data: margin absorption implying slower growth, or term premium implying higher nominal rates for longer.

Until one resolves, sector leadership will keep flipping with the yield, and index-level readings will remain uninformative.

  1. Carry-Over Into Tuesday
  1. The Three Questions Into the FOMC

Which inflation reading wins? Margin absorption — a 2.6-point producer-consumer gap meaning compressed profits — or term premium, meaning higher nominal rates for longer. The curve flattened on 14–15 October and steepened on Monday. The committee meets on 27–28 October without that resolved.

Does the credit concern spread? Oracle’s bonds near junk and CoreWeave’s $50 billion debt load are the acute cases. The question becomes systemic if spreads widen across the roughly $600 billion of AI borrowing documented here, and a December hike at 89% probability is the adverse backdrop.

And do earnings justify the concentration? This is the week it gets tested. DePorre: “The reaction to earnings reports will determine where things are headed.” With technology at roughly 40% of index weight and FactSet expecting nearly 30% S&P third-quarter profit growth against a 2.6-point producer-consumer gap, the bar and the headwind are both high.

Snapshot

Monday, October 19th, 2026 — Theme: “Six Basis Points Undid a Seventeen-Year Record” — The 10-year rose 6 basis points to 5.15% and every sector that rallied on last week’s decline reversed. The equal-weighted S&P fell 0.32% while the cap-weighted index rose 0.41%, and NYSE decliners beat advancers nearly two to one.

Monday answered the question this publication posed on Friday — whether the historic rotation would hold — and answered it in one session. Yields rose modestly and the full reversal followed: utilities down 2.01%, real estate 1.16%, financials 0.83% and healthcare 0.60%, against technology up 1.36%. The conclusion is that the concentration defining this market is a rate phenomenon rather than a sentiment one, and will not resolve until the risk-free rate falls durably. Separately, the AI leverage question moved into the credit market, with Oracle’s bonds reported as “dangerously close to junk.”

📊 Market Sentiment & Bias

The rotation: ⚠️ Reversed in one session. A 6 basis point rise in the 10-year undid every sector move from last week’s seventeen-year record.

Breadth: 🟥 Negative beneath a positive index. Equal-weight down 0.32% against cap-weighted up 0.41%, with decliners beating advancers 1,761 to 945.

Credit: 🟥 The leverage question migrated. Oracle’s bonds reported “dangerously close to junk”; CoreWeave unable to hold a Goldman upgrade.

The curve: ⚠️ Steepened, inverting last week’s message. Term premium reasserting after two sessions of flattening on margin absorption.

Semiconductors: 🟩 Technical relief. The SOX rose 1.61%, ending an eight-session streak, with memory names rebounding from a 22% monthly decline.

Amazon: ⚠️ The third layer challenged. TorchNeuron attacks CUDA switching costs after CXMT challenged memory and credit markets challenged financing.

💡 Top Trade Takeaway: “The Concentration Will Not Resolve Through Sentiment”

Focus: Treat Monday as a decisive test of the rotation thesis that the rotation failed. Recognise that market leadership now flips with the 10-year within single sessions, making the yield the instrument to watch rather than the index. Weight the migration of the AI leverage question into credit as more serious than its equity expression. Watch this week’s technology earnings and whether spreads widen beyond Oracle and CoreWeave.

Logic. The previous edition made a falsifiable claim about last week’s historic rotation — the equal-weighted S&P’s best week relative to technology since 2009. It argued the move had “a mechanical cause rather than a sentimental one,” that the trigger was the 10-year falling 14.6 basis points, and that the rotation “lives or dies on whether yields stay down.”**

Monday tested that directly. The 10-year rose 6 basis points to 5.15%, and the reversal was complete: utilities fell 2.01% after rising 1.10% on Friday; healthcare fell 0.60% after reaching a record on Thursday; financials fell 0.83% after rising 1.03%; real estate fell 1.16%. Technology rose 1.36% after falling 3.00% on Friday. And the breadth signal inverted entirely — the equal-weight S&P fell 0.32% while the cap-weighted index rose 0.41%, with NYSE decliners beating advancers 1,761 to 945.

The conclusion is unwelcome for anyone who read last week as structural broadening. The concentration in this market is a rate phenomenon. It is not investors chasing a theme and it is not a valuation bubble — technology trades at roughly 21 times forward earnings against 32 last October, Nvidia sits below the index multiple, and Micron is near 6.8 times after nearly quadrupling revenue. It is capital occupying the only part of the market where a 5%-plus risk-free rate does limited damage, because net-cash companies with growing earnings are genuinely less rate-exposed than leveraged small caps and bond proxies. Melissa Brown of SimCorp observed on Friday that a theme at 40% of market weight “has often been associated with a market peak.” Monday suggests the resolution will not come through sentiment; it comes when the risk-free rate falls durably — and the 10-year has failed to break below 5% once while failing to hold above 5.3% three times.

The curve reinforces that the market has not settled. A steepening to about 38 basis points, with long yields rising faster than short, is term premium reasserting — the configuration that dominated from mid-August when the 10-year rose 115 basis points from 4.16%. That inverts the message of 14–15 October, when flattening on hot CPI and PPI prints indicated a policy-induced slowdown being priced. Both readings are available from the same data: margin absorption implying compressed profits and slower growth, or term premium implying higher nominal rates for longer. The alternation is why leadership flips session to session.

The most serious development was the AI leverage question entering credit. CNBC reported Oracle’s bonds sit “dangerously close to junk,” and TheStreet carried a headline reading “CoreWeave, Oracle have an interest rate problem.” That migration matters because investment-grade mandates are constrained by rating rather than by view — a downgrade forces selling regardless of opinion, which equity drawdowns do not — and because spread widening at a large issuer raises refinancing costs across the roughly $600 billion of AI borrowing documented here. With CME FedWatch showing an 89% probability of a December hike, credit deterioration into tightening is how a leverage question becomes a funding problem. The qualifications are real: this is a characterisation rather than a rating action, Oracle is an established investment-grade issuer, and the shares rose 1.06% on the day. But CoreWeave giving up a Goldman Sachs upgrade to close down 0.44% while neoclouds around it rose between 2.74% and 6.65% is the market deliberately separating the AI trade from the AI leverage trade.

Calendar discipline: Tuesday 20 October — Netflix reports after the close, into an M Science subscriber estimate cut to 3.80 million from 5.10 million against a 4.10 million consensus; watch whether a lowered bar produces a different outcome than TSMC and Micron received. This week — Tesla and major technology earnings, with DePorre noting “the reaction to earnings reports will determine where things are headed.” 27–28 October — the FOMC decision at 17% hike probability, against 89% for December.
