September 8, 2026
Matthew Krumholz
Domestic participation weakened, reserve liquidity became less supportive, and credit spreads widened modestly. International equities strengthened while the dollar declined.
The VMSI™ Composite declined to 61.9, while institutional capital migration held at 55.3.
The institutional system remains in Selective Synchronization Expansion.

Signal Integrity
Confirmed evidence includes U.S. index performance, all five locked Breadth Version 2.0 measures, Treasury structure, equity and rates volatility, Cboe put/call ratios, Federal Reserve liquidity conditions, corporate-credit spreads, global transmission, the dollar, gold, observable ETF creation-and-redemption activity, and modeled dealer positioning.
Observation conventions remain separate. U.S. market and breadth observations use the September 4 close. Federal Reserve reserve balances and the Treasury General Account use weekly averages through September 2, while Wednesday point-in-time balance-sheet observations remain separately identified. The matched ICE BofA spread comparison runs from August 27 through September 3, preserving the prior report’s convention.
Matched ETF-flow observations are available through September 3, not the September 4 close. Separate units-outstanding data provide weekly corroboration but are not combined into a synthetic total. DFR™ therefore remains Unavailable.
Dealer gamma remains modeled and provisional. Model outputs are not averaged and are not treated as directly observable institutional inventory.
Evidence Rule: Observations determine state. Correlated signals are consolidated. Missing evidence is never replaced by price inference.
Executive Summary
The VMSI™ Composite declined to 61.9 from 62.8 as participation weakened further, reserve liquidity deteriorated, and fixed-income transmission softened.
The deterioration occurred beneath broadly stable capitalization-weighted prices. The S&P 500 gained approximately 0.09%, the Nasdaq Composite 0.40%, the Dow declined 0.27%, and IWM was essentially unchanged.
Breadth told a different story.
The percentage of S&P 500 constituents above their 20-day moving averages declined to 35.38%. Fifty-day breadth declined below half the index to 46.91%, while 200-day breadth declined to 64.01%. New lows also exceeded new highs.
Unlike August 28, deterioration extended materially into the longer breadth horizon.
Fixed-income conditions also reversed part of the prior week’s repair. High-yield and investment-grade spreads widened 2 basis points on the matched weekly convention, CCC-and-lower spreads widened 20 basis points, Treasury duration weakened, and MOVE increased to 73.10.
The strongest offset came from global markets. Developed and emerging international equities strengthened, Japan advanced, China partially repaired, and the dollar weakened. Modeled dealer positioning also remained stabilizing near the index level.
ICMI™ held at 55.3, but its internal composition changed.
Domestic conditions weakened without a corresponding deterioration across every part of the system.
Market Structure
Capitalization-weighted price stability continued to overstate underlying participation.
The S&P 500 finished essentially unchanged at +0.09%. The Nasdaq Composite gained approximately 0.40%, the Dow declined 0.27%, and IWM advanced only 0.09%.
Equal-weight participation weakened more clearly. RSP declined approximately 0.77%, while the locked Participation Integrity Ratio — RSP divided by SPY — declined approximately 0.87%.
Breadth deteriorated across all three moving-average horizons.
Twenty-day breadth declined 6.96 percentage points to 35.38%. Fifty-day breadth declined 5.97 points to 46.91%, crossing below 50%. The 200-day measure declined 4.77 points to 64.01%.
Friday NYSE breadth improved materially, with declining issues outnumbering advancers approximately 1.04 to 1, compared with 1.77 to 1 the prior week. That daily stabilization did not repair the broader structure.
S&P 500 new highs and lows also reversed from 5 to 3 to 3 to 6.
Nearly two-thirds of constituents remain above their 200-day averages. Long-horizon structure therefore remains intact, but deterioration is no longer confined to short and intermediate participation.
Daily stabilization did not establish broader participation repair.
Credit & Liquidity Conditions
Reserve liquidity and credit conditions weakened together.
Average Federal Reserve reserve balances declined approximately $30.4 billion to $2.895 trillion. The average Treasury General Account increased approximately $17.2 billion to $967.9 billion, while Reserve Bank credit declined modestly.
The separate Wednesday endpoint was more constructive: reserve balances increased, Treasury cash declined, and total Federal Reserve assets rose modestly. That contradiction is preserved, but it does not replace the controlling weekly-average convention.
Credit also reversed part of its prior improvement.
High-yield OAS widened from 263 to 265 basis points, investment-grade OAS from 79 to 81, and CCC-and-lower spreads from approximately 1,031 to 1,051 basis points.
The deterioration remained concentrated rather than systemic. Broad spread widening was modest; weaker-quality credit carried the more pronounced deterioration.
Treasury transmission weakened simultaneously. Five-year yields increased approximately 6 basis points, ten-year yields 5 basis points, and MOVE rose from 70.97 to 73.10.
The prior week’s combination of tighter credit spreads, stronger duration, and declining rates volatility did not persist.
Credit softened as reserve liquidity tightened and duration weakened.
Positioning & Convexity
Equity volatility remained contained, but convexity signals divided.
VIX moved from 14.43 to 14.53, VXN from 19.92 to 20.04, and VVIX declined from 86.63 to 84.42.
Tail and rates measures moved differently. SKEW increased from 149.77 to 151.58, while MOVE rose to 73.10.
The Cboe equity put/call ratio declined from 0.62 to 0.58, while the index put/call ratio declined from 0.99 to 0.89.
The Hedging Preference Ratio — CPCE divided by CPCI — increased approximately 4.1% because index put activity declined proportionately more. These measures describe relative option activity; they do not establish changes in absolute institutional hedge inventories.
Modeled dealer positioning remained stabilizing. Dated September 4 estimates placed SPX above modeled gamma-flip levels, although dealer inventory remains unobservable and models differ.
The combined evidence does not justify either a CMX improvement or deterioration.
Lower relative put activity coexisted with higher tail and rates-volatility measures.
Flow & Allocation Behavior
Observable allocation remained active, but full-week flow visibility is incomplete.
Matched observations through September 3 showed approximately $2.2 billion of combined U.S. and international equity ETF outflows and approximately $10.3 billion of combined fixed-income ETF inflows.
Those are four-session totals, not a complete September 4 Friday-close weekly observation.
Separate comparable units-outstanding data showed positive deployment into fixed income, selected benchmark structures, technology, healthcare, utilities, and international exposures.
Technology deployment remained concentrated, particularly in semiconductor exposure. Large offsetting movements also appeared across highly substitutable benchmark ETFs.
Those wrapper changes cannot be treated as independent proof of withdrawal from or accumulation into the underlying asset class.
IC-VMSI™ remains 67.2, unchanged. Observable deployment stayed selective, and the evidence does not establish a broader increase or decrease in institutional core capital force.
Capital remained deployed, but allocation remained selective.
Structural Participation Integrity
SPI declined to 61.4 from 64.2, the largest movement in the Advanced Framework.
All three moving-average breadth horizons weakened materially. Twenty-day breadth declined to 35.38%, 50-day breadth to 46.91%, and 200-day breadth to 64.01%. New lows exceeded new highs, while equal weight underperformed capitalization-weighted exposure.
The five-input breadth architecture remains unchanged. Equal-weight and small-cap behavior provide contextual confirmation rather than additional breadth inputs.
The strongest contradiction was the improvement in Friday advancer/decliner breadth, stable IWM, and the continuing majority of constituents above their 200-day averages.
The evidence therefore establishes meaningful deterioration without demonstrating a broad structural break.
The depth of participation weakness increased even as the final session became less adverse.
Global Propagation Conditions
Global participation strengthened.
VEA gained approximately 0.96%, VWO 1.07%, IEMG 2.24%, VXUS 1.02%, and EWJ approximately 2.51%.
FXI advanced approximately 1.04% and finished above its 20-day, 50-day, and 100-day averages while remaining below its 200-day average. The evidence supports short- and intermediate-horizon repair, not complete long-term normalization.
The dollar index declined from approximately 99.70 to 99.18, reversing the prior week’s currency headwind.
The Global Propagation Ratio — VEA divided by VWO — declined approximately 0.11%, indicating only modest emerging-market outperformance.
Gold declined approximately 0.52%, while Treasury duration weakened. Traditional haven prices therefore did not synchronize into a defensive move.
The international improvement is important because it occurred while domestic participation weakened.
GFP increased to 70.4 from 68.6.
International participation strengthened while domestic breadth deteriorated.
CMX — Convexity Metrics Index
CMX remained 60.4.
Lower VVIX and lower endpoint put/call ratios opposed higher SKEW, higher MOVE, and weaker Treasury duration. Positive modeled dealer gamma provided qualified stabilization but did not override the directly observable volatility evidence.
The unchanged score therefore reflects opposing pressures rather than unchanged risk.
A stronger CMX improvement would require tail and rates-volatility measures to normalize alongside supportive positioning.
Convexity conditions remained mixed rather than uniformly normalized.
Those conditions reduced the strength of the environment through which capital can transmit.
The deterioration remained limited. Credit markets remained orderly, observable fixed-income ETF deployment remained positive, and modeled dealer positioning remained stabilizing.
PDCS measures deployment conditions, not actual capital allocation. Positive flows therefore do not erase weakening transmission conditions, just as weaker asset prices do not establish institutional withdrawal.
Deployment conditions weakened without evidence of broad impairment.
GFP — Global Propagation Framework
GFP increased to 70.4 from 68.6.
Developed and emerging markets strengthened together. Japan accelerated, China repaired at shorter horizons, and the dollar weakened.
The improvement was geographically broader than the prior week.
The strongest contradiction was domestic U.S. participation, which weakened across 20-day, 50-day, and 200-day horizons.
That prevents stronger international performance from being interpreted as broad system-wide synchronization.
Broader regional participation did not amount to broad institutional expansion.
PLMT — Post-Linear Market Structure
The PLMT regime remains Selective Synchronization Expansion.
Domestic participation deteriorated, liquidity became less supportive, credit softened, and duration weakened.
The evidence did not, however, converge into a fully defensive state.
International participation strengthened, observable capital remained deployed, modeled dealer positioning remained stabilizing, and surface equity volatility remained contained.
A defensive transition would require weakening participation to converge with deeper credit stress, persistent liquidity withdrawal, broad observable capital outflows, deteriorating positioning, and weaker global propagation.
A transition toward Broad Participation Expansion would require meaningful domestic breadth repair, stronger liquidity transmission, and wider deployment confirmation.
Neither occurred.
Weekly observations test the implications of the framework. They do not constitute proof or validation of PLMT itself.
Selective synchronization persisted.
What information did the system gain this week?
The prior report identified tighter credit spreads, stronger duration, and declining rates volatility as important offsets to weaker participation.
This week, those conditions partially reversed.
The new information is that capital allocation can remain active even as the conditions transmitting that capital become less supportive.
Three Hidden-State Discoveries
1. Daily stabilization coexisted with deeper structural deterioration.
Friday participation became less adverse and small caps stabilized, yet 50-day breadth declined below half the index and 200-day participation weakened materially.
The strongest contradiction remains that nearly two-thirds of S&P 500 constituents are still above their 200-day averages.
Daily improvement did not establish structural repair.
2. Fixed-income allocation persisted while transmission weakened.
Positive fixed-income ETF flows coexisted with wider spreads, weaker duration, higher MOVE, and less-supportive reserve liquidity.
Allocation and transmission therefore delivered different information.
Capital continued to deploy into fixed income while the surrounding transmission environment weakened.
3. Put/call ratios moderated without tail-risk normalization.
Both endpoint put/call ratios declined while SKEW increased and MOVE moved higher.
Lower VVIX and supportive modeled dealer positioning provided meaningful counterevidence, but did not establish uniform risk normalization.
Immediate hedging activity eased while asymmetric risk remained elevated.
What did VMSI™ discover that price alone did not reveal?
Major U.S. indexes showed little net movement.
VMSI™ showed deeper participation deterioration, weaker reserve liquidity, softer credit transmission, and weaker duration — alongside stronger international participation and continued selective capital deployment.
Price stability did not imply unchanged institutional conditions.
Price held. Structure weakened beneath it.
Earnings Topline
Earnings resilient, selective.
Technology and enterprise-infrastructure results remained strong, while consumer results were less uniform.
Earnings were not score-determining. The institutional state was established through participation, liquidity, positioning, credit, flows, and cross-asset transmission.
ETF Capital Flows and Dealer Positioning improved. Cross-Asset Confirmation strengthened modestly.
Liquidity Footprint and Credit Market Confirmation weakened.
The evidence therefore does not establish either broad institutional accumulation or broad withdrawal.
Selected allocation remained active, international participation strengthened, and modeled dealer conditions stabilized. At the same time, domestic breadth deteriorated, reserve liquidity weakened, and credit confirmation softened.
ICMI™ Confirmation: Institutional migration remained broadly stable while its internal composition changed.
Final Institutional Assessment
Institutional market conditions weakened modestly during the week ending September 4.
The VMSI™ Composite declined to 61.9 as participation deterioration extended deeper into the breadth structure, reserve liquidity became less supportive, and credit and Treasury transmission weakened.
The change is meaningful because the prior week’s principal fixed-income offsets partially reversed.
The deterioration nevertheless did not become systemic.
Capitalization-weighted prices held. Surface equity volatility remained contained. Modeled dealer positioning remained stabilizing. International participation strengthened across developed and emerging markets. Observable capital deployment remained selective rather than broadly negative.
ICMI™ remained 55.3, but its composition changed as stronger flow, dealer, and cross-asset evidence offset weaker liquidity and credit confirmation.
The September 4 state is therefore not generalized risk deterioration.
It is weaker domestic institutional structure occurring alongside stronger global participation and continued selective capital deployment.
Current Regime: Selective Synchronization Expansion.
Participation is too weak for a broad-expansion upgrade.
Global participation, positioning stability, contained surface volatility, and continued observable deployment prevent a defensive transition.
The regime would lose confirmation if long-horizon participation deterioration converged with deeper credit widening, persistent reserve-liquidity withdrawal, weakening positioning, broad observable capital outflows, and deteriorating global propagation.
That system-level convergence is not present.
Domestic Structure Weakened. Global Participation Strengthened.
About VMSI™
The VICA Institutional Market Sentiment Index (VMSI™) is an observational market framework designed to measure the institutional conditions shaping market behavior before those conditions become fully reflected in price.
Rather than interpreting indicators independently, VMSI™ measures relationships among participation, liquidity, credit, positioning, capital deployment, and global propagation to identify changes in underlying market organization.
Each weekly publication integrates observable market data, proprietary relationship metrics, and independent structural validation to identify the prevailing institutional market state.
Weekly evidence tests observed relationships. It does not prove the theory.
Contradictory evidence defines uncertainty. Falsification conditions determine when the measured state must be revised.
IC-VMSI™ Definition
IC-VMSI™ measures institutional core capital-force and deployment behavior across passive and benchmark-linked fund structures.
The framework evaluates observable allocation, creation-and-redemption activity, ownership structures, portfolio positioning, and benchmark-linked investment behavior rather than attempting to identify individual institutional trades.
Price, momentum, trading volume, and price-driven AUM appreciation alone do not establish institutional capital deployment.
