The Week in One Paragraph

This was the week the rotation stopped being a theme and became the tape. The Dow gained 0.67% while the Nasdaq Composite fell about 4.5%, its worst week since late June, and the S&P 500 lost 1.95%: money left the AI complex and its creditors and hid in health care, staples, energy, and banks. Two hot inflation prints (September CPI at 3.7% on the year Wednesday, PPI up 1.3% on the month against +0.5% expected Thursday) were absorbed without a flinch midweek, and then Friday the AI debt unwind took the whole index down anyway: Nasdaq -2.14%, CoreWeave down about 12%, the VIX closing at 19.99. The stress still lives in credit, not in the broad tape: high-yield spreads at 324bp, CoreWeave CDS in record ground, Oracle CDS at a record 288bp. The desk's first ledger week went the other way: three of the four published setups triggered on pullbacks and held their stops through Friday's selloff, and the fourth never filled and is scored that way. Into next week the SPY $758 scenario is half-armed, and Wednesday's Meta and Tesla prints are the event that matters.

Market Breadth

Above 20-day average57.53%
Combined breadth score (source label)47.02%, Neutral

Thursday's readings are the latest from a dated source at publish time; Friday's breadth figures are not printed because no dated source for them was available this morning. The split is the story either way: short-term breadth repaired fast Thursday (57.53% above the 20-day) while the 50-day reading still shows the damage. Advance/decline counts, new highs/lows, and the put/call ratio remain omitted, as they were in Friday's issue, until the feed is proven.

Inflation and the Fed

Two hot prints, absorbed. September CPI printed 3.7% year over year on Wednesday. September PPI followed Thursday at +1.3% on the month against +0.5% expected, +6.3% on the year, with core up 0.7% on the month. The market's answer, both days: yields down, defensives bid.

The chair pushed back gently. Chair Warsh, at the IMF meetings in Bangkok Thursday night, declined to preview the Oct 27 to 28 FOMC meeting and called the AI path "very bumpy." Market odds of an October hike, about a third midweek, fell to about 15% after his remarks. The Fed is now in its pre-meeting blackout: no Fedspeak next week, by rule.

Credit Watch

Credit levels are the Oct 15 readings published Friday; no newer dated credit snapshot was available this morning, so Friday's levels are not printed. The equity side confirmed the direction Friday: the AI complex led the market down.

AI Cycle Risk Meter path across the week
The meter climbed all week without a regime flip: 37 at the week's start, 44 in Thursday's edition, 45 on Friday, Orange throughout. The foreign equity-flow trigger moved from Watch to Yes on Friday after the KOSPI fell 7.57% on Oct 15 with heavy foreign selling.

The Scoreboard, Full

The expiry rule, stated plainly from this first Ledger and applied from day one. "An entry that never triggers expires after 5 sessions. A triggered setup resolves at target 1, the stop, or after 15 sessions, whichever comes first. Expired setups are scored as closed, flat, and printed in the Ledger that week." Applied to the Oct 15 cohort, counting forward from Oct 15: unfilled entries expire at the close of Wednesday, Oct 21; triggered positions resolve by the close of Wednesday, Nov 4 at the latest, at target 1 or the stop if those come first. Nothing in the ledger drifts open forever again.

Week one line: 4 setups published (Oct 15 issue). Triggered and open: 3 (CVX, AAPL, MPC). Never triggered: 1 (GILD). Resolved: 0. No wins and no losses booked, and nothing quietly dropped.

CVX Chevron
TRIGGERED, OPEN
Entry $218.80 to $220.50   Stop $213.70   Targets $229 / $233
Fri close $224.99
T1 $229
T2 $233
Stop $213.70
Entry zone

Filled on Thursday's dip (low $218.05). Friday: open $221.85, high $225.31, low $220.41, close $224.99 (+2.59%), the best day of the three live names on the week's worst tape, and the close clears the $223.46 reclaim trigger named in Friday's swing report. Target 1 not reached. Illustrative mark at the zone midpoint: +2.4%. Session 2 of 15 used. Invalidation: close below $213.70

GILD Gilead Sciences
NEVER TRIGGERED
Entry $151.00 to $152.50   Stop $147.40   Targets $157.29 / $160.07
Fri close $156.19
T1 $157.29
T2 $160.07
Stop $147.40
Entry zone

Thursday's low was $156.02 and Friday's was $155.62, the closest approach of the week, still $3.12 above the top of the entry zone, while the price ran through both published targets unfilled. Under the rule printed above, the entry has used 2 of its 5 sessions and expires at Wednesday's close if it still has not filled. The score stands as published: no fill, no win. At $156 the chase is a different trade with no published stop, and this page does not bless it.

AAPL Apple
TRIGGERED, OPEN
Entry $342.50 to $344.00   Stop $337.50   Targets $355 / $360
Fri close $343.46
T1 $355
T2 $360
Stop $337.50
Entry zone

Filled on Thursday's dip (low $341.60). Friday: open $346.09, high $347.82, low $340.46, close $343.46 (+0.43%), back inside the zone and the only Mag 7 name green on the day. Still the weakest posture of the three: the position sits almost exactly at its entry, with earnings on Nov 2 inside the position window. Session 2 of 15 used. Invalidation: close below $337.50

MPC Marathon Petroleum
TRIGGERED, OPEN
Entry $478 to $482   Stop $469   Targets $500 / $510
Fri close $478.07
T1 $500
T2 $510
Stop $469
Entry zone

Filled at Thursday's open; the low that day was $469.07, seven cents above the stop, the closest call in the young ledger's life. Friday: open $480.61, high $484.25, low $470.56, close $478.07 (+0.24%), back at the bottom of the zone with the stop untested. Reduced size, as published. Any intraday break of $469.07 is the early warning. Session 2 of 15 used. Invalidation: close below $469

The running ledger. The public daily ledger opened with the Oct 15 issue and stands at: 4 published, 3 open, 1 never triggered, 0 resolved. Every call is checkable against the archive: the Oct 15 issue made them and the Oct 16 issue carried them live.

The engine's audited record (full audit, Oct 2, 2026): win rate 61.9% across 651 resolved patterns (403 wins, 248 losses) out of 663 tracked, expectancy +0.08R per signal, average win +2.36%, with 12 patterns still open at the audit. Aggregates carry their audit date; the daily ledger above is the record now being built in the open, one week at a time.

What Worked, What Didn't

What worked

The retest entries. All three fills came on weakness, not strength: CVX and AAPL filled on Thursday's dips into their zones, MPC at Thursday's open. On Friday, a -1.09% index day with the Nasdaq down 2.14%, all three stops finished the week untouched. Buying the pullback in a rotation tape is the desk's whole method, and week one it behaved.

The rotation read. Dow +0.67% on the week against the Nasdaq's -4.5%: the desk's live names sit in energy and a defensive-leaning mega-cap, not in the complex that broke. CVX rose 2.59% on Friday itself.

Refusing the chase. GILD at $157 and then $156 had no published stop and no zone. Staying out kept the ledger honest and the risk defined.

What didn't

GILD is the week's paper miss. The direction call was right and both targets printed, unfilled. The no-fill rule cost real money this time. It is still the rule: a scoreboard that books unfilled targets is marketing, not accounting, and the expiry clock now gives the entry five sessions and no more.

MPC's seven cents. The stop survived day one by $0.07. A zone entry in a name up 15% in a month carries gap risk a stop cannot guarantee against. Reduced size was the right call and stays the template for parabolic entries.

AAPL's posture. The weakest of the three live names: two sessions in, the position is flat at its entry with the Nov 2 earnings print inside its window and a hard expiry of Nov 4 behind it.

Rotation Review

Five-day sector returns to the Oct 15 close
The week's leadership, five sessions to Thursday's close: staples, energy, health care, and real estate at the top; technology alone at the bottom. Friday extended the pattern rather than breaking it.

Sector table as published Friday (returns to the Oct 15 close; Friday's sector closes were not available from a dated source this morning and are not printed). The week in one breath: the five-day column is the rotation, staples +6.10% and energy +5.05% against technology -6.06%, with semiconductors down 9.73% from Oct 1 to 15. Friday's Mag 7 closes told the same story inside tech itself: META -3.72%, GOOGL -2.47%, TSLA -2.14%, MSFT -1.94%, AMZN -1.89%, NVDA -1.42%, and AAPL the group's only gainer at +0.43% (official closes). Leadership now sits outside the AI complex, and nothing this week argued it is coming back yet.

Levels That Matter Next Week

The SPY $758 scenario, printed precisely: half-armed, watch-listed, not live. The index half of the condition triggered Friday (S&P close below 7,700). The rates half did not (10-year 5.09% against a 5.20% trigger). Both halves together make it live; one half makes it a watch.

Next Week Preview: Oct 19 to 23

DAYEARNINGS THAT MATTER TO THIS DESK
Mon 19Light day. Steel Dynamics (STLD), Fifth Third (FITB).
Tue 20Before open: GE Aerospace (GE), General Motors (GM), 3M (MMM), RTX, Capital One (COF), KeyCorp (KEY), Chubb (CB), Halliburton (HAL), Northrop Grumman (NOC). After close: Netflix (NFLX), Intuitive Surgical (ISRG).
Wed 21The week's peak. Before open: Philip Morris (PM, release about 7:00 AM ET per the company's own announcement; Zacks consensus $2.31 EPS), AT&T (T), Abbott Labs (ABT), Thermo Fisher (TMO), CME Group (CME). After close: Meta Platforms (META), Tesla (TSLA), IBM, Lam Research (LRCX), Texas Instruments (TXN).
Thu 22Before open: Blackstone (BX), Procter & Gamble (PG), Spotify (SPOT).
Fri 23Before open: American Express (AXP), SLB.

Dates and timing cross-checked across two public calendars on Friday evening; PM's day was disputed between the two (Tuesday vs Wednesday) and is printed on Wednesday per PMI's own Oct 14 announcement of an Oct 21 release. Consensus and prior figures for the rest join with the weekday desk editions rather than being estimated here. Wednesday after the close is the week's single biggest window: META and TSLA together set the AI complex's tone for the following week.

Fri 10:00 AMMichigan Consumer Sentiment, final (Oct)

A quiet data week by design: no CPI, PPI, or payrolls. The Fed is in blackout all week ahead of the Oct 27 to 28 meeting, so nothing official rescues or rattles the tape. The tier-one cluster lands the week after: FOMC decision Wed Oct 28, Q3 GDP and September Core PCE Thu Oct 29.

Two scenarios that flip the regime

The downside arms. The 10-year reclaims 5.20% while the S&P holds below 7,700: the SPY $758 scenario goes live, the AI credit stress gets an index problem to match it, and the desk's live energy setups are managed against their stops, not hope.

The repair. META and TSLA print without a credit scare, the S&P closes back above 7,700, and the 10-year stays under 5.20%: the broadening resumes toward 7,805 and the record, and the week's lesson becomes that the rotation, not the unwind, was the story.

Watchlist for Monday

NAMEWHY IT CARRIES INTO THE WEEK
CVX, AAPL, MPCThe three live ledger positions. Stops unchanged at $213.70, $337.50, and $469; targets unchanged. They resolve in this Ledger, in the open, by target, stop, or the Nov 4 expiry.
GILDThe entry clock: 2 of 5 sessions used. If it never trades into $151.00 to $152.50 by Wednesday's close, the entry expires, scored closed and flat. No chasing it at $156.
S&P 500 at 7,700Monday's close above or below the lost line sets the week's posture before any single stock matters.
META and TSLAWednesday after the close. The weakest chart in the Mag 7 and the complex's bellwether report on the same evening.
Semiconductors (SOX)Eight straight down sessions into Friday. The first higher low is a watch item, not a buy signal.
PMWednesday before the open, a staples leader reporting into a defensive bid, and a name this desk has watched before.
