IC-VMSI™ — Institutional Core Buys Index

June 11, 2026

The Problem

Most market frameworks measure conditions.

They measure prices, valuations, earnings, economic activity, volatility, and investor behavior.

These variables describe what happened.

They do not directly measure the source of capital entering the system.

This distinction has become more important as passive and benchmark-linked investment structures have grown as a share of market participation.

A growing portion of market demand now originates from index funds, retirement plans, target-date funds, model portfolios, and benchmark-linked mandates.

These structures allocate capital according to rules.

As a result, market conditions and capital allocation are no longer equivalent observations.

A market may strengthen because conditions improve.

A market may also strengthen because benchmark-linked capital continues to enter the system.

Most frameworks measure the first.

IC-VMSI measures the second.

IC-VMSI measures institutional allocation force. VMSI measures the conditions that emerge from it.

Definition

The Institutional Core Buys Index (IC-VMSI™) measures institutional capital deployment through passive and benchmark-linked investment structures.

The framework estimates the direction, magnitude, and persistence of benchmark-linked allocation across core equity, fixed income, and international investment vehicles.

IC-VMSI does not measure sentiment, valuation, forecasts, or opinion.

It measures observable capital deployment.


Conditions and Forces

A distinction exists between conditions and forces.

Conditions describe the state of a system.

Forces describe the mechanisms acting upon that system.

Most market frameworks measure conditions.

IC-VMSI measures force.

The central question is not:

What is the market doing?

The central question is:

Who is supplying the capital behind what the market is doing?


Why IC-VMSI Exists

Traditional market models were developed when active security selection represented the dominant mechanism of capital allocation.

That structure has changed.

Today, a significant share of capital is deployed through benchmark-linked allocation systems governed by fund flows, contribution schedules, rebalancing processes, and index construction rules.

These flows can influence market structure independently of valuation changes, earnings revisions, economic forecasts, or investor opinion.

IC-VMSI was developed to measure that force directly.


Advanced Signal Layer Integration

Within the VICA Institutional Market Sentiment Index (VMSI™), IC-VMSI functions as part of the Advanced Signal Layer alongside SPI, CMX, PDCS, and GFP.

VMSI measures system conditions.

IC-VMSI measures institutional accumulation force.

The frameworks are designed to be evaluated together.

A rise in IC-VMSI alongside a weakening VMSI may indicate continued accumulation despite deteriorating system conditions.

A rise in VMSI alongside a weakening IC-VMSI may indicate improving system conditions despite declining accumulation.

These divergences represent hidden-state relationships that may not be visible through price performance alone.


Hidden-State Objective

The purpose of IC-VMSI is not to explain market performance.

The purpose is to identify relationships between institutional capital deployment and system conditions.

Accumulation may strengthen while participation deteriorates.

Accumulation may weaken while breadth improves.

Benchmark-linked demand may increase while concentration rises.

Liquidity conditions may stabilize while capital deployment contracts.

These relationships may emerge before they become visible through traditional market indicators.


Core Principle

Most market frameworks explain what happened.

IC-VMSI measures who supplied the capital that made it happen.
