[Deep Dive] Stocks Stay Range-Bound With a Downside Lean Until Core PCE

Where we stand

The question for October is whether the next move in US stocks is a trend or a range, and our provisional answer is a range with a mild downside lean that lasts until the Fed decides on Oct 28 and September core PCE (the Fed’s preferred inflation gauge, excluding food and energy) arrives on Oct 29. The base case carries 52% over the coming week and 50% over the coming month, just over half at both horizons. If the bottom of that range gives way before the two releases, we expect the decline to stall rather than snowball for as long as credit markets show no stress. That condition is the core of this edition.

The week and the month share a shape but not a test. The coming week’s calendar is light: housing data, jobless claims, a flash PMI and final Michigan sentiment. Price action over those days is mostly positioning and noise. Over the month, the Fed decision and core PCE land two days apart, and the market gets its answer to the stagflation-versus-reflation question. That is why the bear case is a little heavier at one month (28%) than at one week (26%). With growth solid and inflation hot, a core PCE print only slightly above expectations could tip the calm base path into the stagflation branch.

What this edition adds is the mechanism behind the range. Option dealers sit in “negative gamma”: to stay hedged, they must sell futures into falling prices and buy into rising ones, which exaggerates swings in both directions instead of lifting prices in a steady grind. Three facts tilt the range lower. Inflation pressure scores as hot, with CPI at 3.7%. Crude has already slipped below the consolidation baseline used in our earlier analysis, so part of the oil fade is behind us. And investor sentiment has fallen to extreme fear, with the Fear & Greed index down at 18, a reading that signals extreme fear.

The week ahead

Positioning and noise describe a week whose base path ends in a probe of support rather than a confirmed break. The three paths:

Base. The state: housing data lands on Oct 20, jobless claims on Oct 22, and the S&P flash PMI and final Michigan sentiment on Oct 23, while the events that set direction fall in the following week. The catalyst: with dealers in negative gamma, ES (S&P 500 futures) probes the SPY Supertrend pivot. That pivot is a trend-following line, and trends often flip when price crosses it. During the session ES may dip toward a support cluster formed by the weekly EMA20, a 20-week moving average, and the lower Keltner band, a volatility-based floor. What confirms it: rallies stall at a resistance band built from VWAP (the volume-weighted average price), the EMA20 and the prior close.

Oversold semiconductors and crowded put hedges limit how far sellers can push. At the same time, no strong buyer is likely to step in before the Fed, so the range has a lid as well as a floor. Elsewhere in the base week, NQ (Nasdaq 100 futures) stays boxed between nearby support and its relief line. Gold holds a tight range as a tail hedge, crude consolidates after its pullback with no reason to chase it, copper stays flat, and Bitcoin tracks equity risk appetite.

Bull. The state: confirmed Hormuz de-escalation pulls crude lower and eases the energy burden on consumers. The catalyst: traders price out part of the December hike risk, short-end yields fall, and the CBOE Skew index, which tracks demand for crash protection on the S&P 500, deflates while VIX eases. What confirms it: QQQ reclaims its relief line. Negative gamma then forces dealers to cover and chase prices higher, pulling NQ toward QQQ’s max-pain level, the price at which the most options expire worthless and toward which prices often drift near expiry. A firm flash PMI on Oct 23 would add reflation support. This path stays a minority outcome because its strongest catalysts, a benign core PCE print and a calm Fed meeting, fall after the week ends.

Bear. The state: ES closes below the SPY Supertrend pivot for two straight sessions. The catalyst: the VIX futures curve inverts, meaning near-term fear is priced above longer-term fear, and high-yield spreads keep widening on headlines about AI-credit contagion. High-yield spreads are the extra yield investors demand to hold risky corporate bonds. A renewed Hormuz escalation could add an oil-driven stagflation shock on top. What confirms it: negative gamma speeds selling down the support ladder toward the EMA200, the 200-period moving average, and NQ loses nearby support as semiconductors extend their losing streak.

The evidence against the bear week is solid today. High-yield spreads sit at a calm 3.23%, the VIX curve has not inverted, and a Fear & Greed reading of 18 says a lot of fear is already priced.

The strongest objection to a quiet range sits in tech and small caps. IV rank places today’s implied volatility within its past-year range on a 0-100 scale. For QQQ it is a normal 53, while SPY’s reading is low. RTY carries the most negative dealer gamma of the group. Stress in tech and small caps could therefore break the range faster than SPY’s calm suggests, and equity exposure carried through the Nasdaq or small caps is likely to absorb more of the week’s swings than the same exposure in the S&P 500.

The three bear warnings are also the bridge to the month. Two closes below the pivot, an inverted VIX curve and high-yield spreads drifting wider are early signals for the one-month bear case. If none of them fires this week, the odds of a credit-confirmed slide next month fall with them.

The month ahead

Whether those early signals turn into a real credit response will be settled by two releases two days apart at the end of the month.

Widening the window to a month does not fatten the upside tail. The bull case holds at the same weight while the bear case edges higher, which tells us the month’s risk sits more below the market than above it.

Base. The state: the Fed holds on Oct 28 with a hawkish tone, and core PCE lands near the survey band the next day. That keeps the three-month inflation trend below the level that would trigger the stagflation scenario, with short- and long-end yields range-bound and the dollar flat. The catalyst: ES breaks the Supertrend pivot and probes the lower support ladder, the area where the Skew index points to a likely drawdown zone. What confirms it: oversold semiconductors bounce and ES mean-reverts toward the middle of its range.

On the same path, NQ trades in a range below its relief line, with QQQ max-pain acting as a ceiling. Oil fades from stretched levels without collapsing, and high real yields (bond yields after expected inflation) keep gold capped.

The strongest dissent comes from inflation. Michigan one-year inflation expectations sit at 4.7%, so even a small upside surprise in core PCE could move this calm base into the stagflation branch quickly. The closest historical analogue is the 2017-18 period of synchronized global growth. The next is the 1995-97 mid-cycle soft landing. Both share today’s solid growth and calm credit but not its hot inflation and oil, so they likely overstate the upside.

Bull. The state: a soft core PCE print, confirmed Hormuz de-escalation and a Fed hold arrive together and push the heavily priced December hike odds in a dovish direction. The catalyst: the 2Y yield falls, and the 10Y breaks back below the top of its range without high-yield spreads widening. Crowded bearish positioning then amplifies short covering, fed by four things: elevated Skew, heavy demand for semiconductor puts, a deeply oversold QQQ and negative dealer gamma. What confirms it: QQQ reclaims its relief line as VIX eases and extends toward its Bollinger midline and upper band, while ES pushes toward the Goldilocks objective. A rally that catches a market positioned for protection is what traders call a pain trade.

The hurdle is steep, though. A web-search snapshot of market pricing for the Oct 28 meeting, which we could not verify, shows 0% odds of a cut, and core PCE runs at 3.0%. Both show how far the Fed still sits from offering relief.

Bear. The state: one of four triggers fires. They are a hot core PCE print, a policy-error hike into weak payrolls, Hormuz escalation that drives crude back toward its cycle high, and AI-credit distress spilling into high yield. The catalyst: high-yield spreads widen past the stress line and the VIX curve inverts, while stocks and bonds move together, so bonds fail as a hedge. What confirms it: negative gamma extends the Supertrend break through the support ladder toward the EMA200 and the recession target, and NQ breaks below QQQ’s EMA200 with semiconductors at the center of the damage.

Today’s data stand in the way. High-yield spreads at 3.23% are calm, and the ISM PMI at 54.5 still shows expansion, so several triggers would need to fire together before this path opens.

Of the three paths, the base path has the stronger support today. The one observation that would move us toward the bear case is high-yield spreads breaking through the stress line while the VIX curve inverts at the same time. Until credit cracks, a decline reads better as a test of the lows than as a change of trend.

Three variables will move the weights over the month.

Inflation and the Fed come first. Producer prices are running ahead of consumer prices, with a PPI-CPI gap of +2.6pp, which leaves room for cost pressure to pass further into consumer prices. The same unverified snapshot puts the odds of a hold at the Oct 28 meeting at 72.3%. With no cut priced at all, the risk of a hike cannot be waved away. If December hike odds stay elevated after the Oct 28 statement and press conference, the bull case loses its premise.

Hormuz and oil come second. Crude’s elevated price rests on a geopolitical premium with little confirmation from physical supply. If de-escalation headlines are confirmed by physical flows, the energy burden and hike fears ease together and the bull path opens. Renewed escalation would instead enlarge the energy-led stagflation shock.

Credit comes third, and it carries the most weight in this month’s call. High-yield spreads stay calm and the VIX futures curve has not inverted, so credit is not confirming the bear path. The risk is AI-credit headlines: if they turn into a steady drift wider in high-yield spreads, credit starts confirming the pivot break, and tech and semiconductors lead the losses. For anyone holding stocks, the direction of high-yield spreads gives the earlier warning; the size of the index’s drop gives the later one.

Cross-asset alignment

If credit is the yardstick for how far stocks can fall, oil and gold set the direction for most of what sits outside equities. Lining up each asset’s one-month path makes the pattern visible.

Only oil and gold hold up on the path where stocks fall, and oil is also the one that loses ground on the path where stocks do well.

Oil moves against stocks at both horizons. On the bear path it carries the supply shock and rises; on the bull path it slides with de-escalation. The order in which that inverse link spreads is clear. Renewed Hormuz escalation drives crude back toward its cycle high, the energy-led stagflation shock pushes long yields higher, and equities lose valuation support. In that phase the working hedges are gold and oil. While stocks and bonds move together, long bonds do not cushion an equity drawdown, so the cushioning that bonds used to provide falls to oil, gold and cash. For portfolios that hold oil as a buffer against falling stocks, the buffer works only on the escalation side; on the de-escalation side it is one more asset that falls.

Gold enters this edition as insurance against extreme events, not as a directional bet. Our recent gold calls missed direction, so our conviction that gold works as a hedge on the bear path is low as well. On the base path, high real yields cap it. A gold position held for price gains is unlikely to be rewarded on this month’s base path; held as insurance, it earns its keep only if the bear path arrives.

Silver and copper trade as growth beta, meaning they move with growth expectations: they rise together on the bull path and fall together on the bear path. Copper staying flat for now leaves the growth-scare reading unconfirmed. Bitcoin follows equity risk appetite.

Options flow on exchange-traded funds shows a different texture of protection demand for each asset. The put/call ratio counts puts traded per call, a gauge of demand for protection.

The highest put/call ratio belongs to small caps. The tech and small-cap break risk flagged for the week is already visible in options demand, not only in dealer positioning.

Outside views

The oil and gold asymmetry was also a frequent theme in outside commentary this cycle. Many accounts repeated one another, though, and few signals passed our quality screens, so outside views changed none of our scenario probabilities.

First, options flow over the week. An options-flow analyst reads the elevated SPY put/call as hedging rather than liquidation, with mildly bullish dark-pool prints and QQQ’s max-pain pull in view. Our quantitative check is the options data itself, where SPY’s put/call ratio stands at 1.4. Our reading is one step more cautious. The observation fits the weekly range, but a high put/call ratio shows demand for protection, not how much protection is already held.

Second, the macro view over the month. A macro strategist sees oil and hot inflation prints keeping stagflation risk alive while credit and the volatility term structure stay calm, and expects the Fed decision and PCE to set direction. Our check is high-yield spreads at 3.23%. We treat this view as the same variable that starts the one-month bear path, but we do not use it to raise the bear probability until credit indicators move.

Third, energy. An energy-market commentator keeps Hormuz supply risk as the dominant oil story but notes the lack of confirmation that physical supply has tightened; talk of the premium fading is present but not the consensus. Our check is USO’s options flow, where dark-pool prints lean bearish, though that proxy is less reliable. We focus on exactly this gap between strong headlines and weak physical confirmation, because it is why oil can surprise the most in either direction.

Taken together, outside commentary did not give us a direction. It gave us one warning: the surprise in oil can be large on both sides.

What would change our view

The warning about an oil surprise carries straight into the conditions that would retire each scenario.

The first condition to be tested is the floor of the weekly base case. Two closes below support could on their own still be a wobble inside the range. If the VIX/VIX3M ratio moves above parity and high-yield spreads widen quickly in the same window, the base case is tilting bearish. What matters is whether price, volatility and credit point the same way at once. Contango, for reference, means longer-dated volatility is priced above near-term volatility, the normal state of a calm market.

Over the month, the heaviest condition is core PCE on Oct 29. A print at or above the hot threshold with the 2Y breaking its range top retires the base case, and so does a Fed hike into weak payrolls. A benign print and a Fed hold without a hawkish surprise retire the bear case first.

The hierarchy between the horizons follows from that. The weekly base case can be retired by price and volatility alone, while the monthly bear case needs credit to confirm it. The weekly call moves first, and the monthly call follows only after the credit data and the inflation release have both had their say.

So what: the blind spot to keep in view is oil. Its price leans on a geopolitical premium rather than physical supply, and long oil is a crowded trade, so a single headline could gap it higher or lower faster than our ranges assume.

Asset allocation view

That oil gap risk is why the starting point for allocation is surviving any of the three paths rather than maximizing return.

In the core, our view keeps index exposure but at a size clearly below normal. Growth and earnings revisions remain supportive enough to keep a base of equities and real assets. Against that, the overall risk grade is watchful (YELLOW) and conviction across our two forecasting models is mixed. Bonds appear only at short duration, and gold, silver, copper and Bitcoin sit alongside as small positions.

The tactical side of the view stays small and range-minded. It treats the expected range and the crowded oil premium as features of the market rather than as directional calls, and it holds off on directional bets until the Fed and core PCE resolve.

The hedge side centers on index put spreads and gold. A put spread buys a put and sells a lower-strike put, which lowers the cost of protection but caps the payout. With SPY implied volatility low, index protection is cheap, and gold covers geopolitical tail risk. Small oil call options round out protection against escalation. With long bonds no longer protecting stocks, oil takes over part of the defense against the stagflation-and-escalation path.

Cash and T-bills are one of the heavier parts of the view. That is room kept to add risk once the Oct 28-29 releases narrow the market to one path, instead of guessing ahead of them.

The weak points are plain. The weight on gold rests on its hedge role rather than on proven forecasting skill, and with long bonds unable to defend, protection depends on cash and options. The setup lags most on the bull path: if inflation cools clearly and the pain trade runs all month, a deliberately small equity base would not keep up with the rally.

Closing

Staying small and patient is preparation for a run of releases. The order to watch:

In the end, this month’s question comes down to where the bottom of the range holds before core PCE. Our current answer hangs on credit: as long as high-yield spreads stay quiet, a decline inside the range reads as a test of the lows. If core PCE breaks that balance, we think the break is slightly more likely to run downward than upward.
