Part of Sentiment as Substrate by Adrian Morris
Chapter 11Empirical Implications & Future Research
Methodology
The ideas presented in this essay can help formulate empirically testable predictions; with that said, a clarification on methodology is necessary. The conclusions of this essay imply that any attempt to decompose price movement into a sentiment component and a non-sentiment component will fail. This is not due to measurement limitations, or a flaw in methodology, but because no sentiment-free residual exists to isolate. What can be measured empirically is how sentiment distributes itself across distinct channels by means of valuation anchors, narrative conviction, capital concentration, reflexive feedback, and mechanical market structure. The relevant question is not “how much” of price is a result of sentiment, but how sentiment flows through market mechanisms and in what proportion relative to one another.
Operationalizing Sentiment
Establishing a new theoretical framework requires the premises behind the conclusions to be conceptually stress tested and validated across several modes before any empirical work can follow. If the assumptions driving the theory are wrong, any derived metrics are statistically meaningless. Exposing the Anchor of 1 as a universal mathematical property in valuation provides the interpretive context that allows us to operationalize existing data as sentiment data and moves sentiment drift from a useful metaphor to a derivable, observable quantity. What changes is not data but its interpretation: mNAV, P/E, Price-to-Book, and every other valuation ratio cease to function exclusively as descriptions of price relative to a reference metric and become readable as a time series of collective belief. This reclassification is not approximating sentiment through an intermediary; if sentiment is constitutive of price formation, its direct quantifiable expression is the distance from the anchor.
Initial Findings
While a full empirical decomposition is beyond the scope of this conceptual paper, subsequent research will demonstrate how this framework is operationalized. Nonetheless, initial analysis suggests these dynamics are already observable in current markets. I performed a Variance Decomposition of Strategy (MSTR) price action using Multivariate Linear Regression1 and Shapley Attribution2 value methods to test these dynamics, and found that narrative expression channels in the form of directionality of Bitcoin and Options Market activity, explain orders of magnitude more return variance than strictly mechanical corporate capital events such as ATM Equity Offerings. This is consistent with the claim that sentiment-driven positioning operates as a foundation of market activity rather than as a single variable among many and acts as a testable use case for both asset-driven and earnings-driven equity premiums and valuations
Testable Predictions
If narrative context is what drives premiums above parity, then companies operating under weaker or less developed narratives (limited analyst coverage, lower media presence, fewer identifiable competitive advantages) should trade closer to natural or historical parity than those in richer narrative environments. This should hold true even when accounting for financial performance. The Bitcoin Treasury Company space provides a natural testing ground for this thesis where firms with less developed narratives than Strategy (MSTR) should display mNAV values closer to (or below) 1. Additionally (at the time of this writing) the severe price correction in Bitcoin over the course of several months, and the extreme contraction in mNAV multiples across the space, may indicate the fragility of narratives that lack sufficient durability to sustain a market premium.
Among more “traditional” equities, in addition to measuring potential sentiment drift via equity multiples over time, added volatility around earnings or related news events that challenge narrative durability should provide insight into sentiment dynamics through price action. If narrative context is ambiguous, whether through sector disruption, regulatory uncertainty, or leadership transition, the divergence in analyst price targets should likely increase independent of changes in underlying financial viability or market volatility. This constitutes another observable channel through which sentiment expresses itself, one that the framework established in this essay makes directly measurable.
Companies such as Nvidia (NVDA), Palantir (PLTR), and Tesla (TSLA), whose valuations carry significant narrative premiums, should exhibit greater price target variance during periods of narrative instability than companies whose multiples trade closer to historical parity. Because existing narratives are well established and require reactivation rather than construction, price corrections that align with narrative restoration should recover faster than those that follow the introduction of new information.
