Intelligence your competitors
do not have yet
ContextQuant adds a contextual intelligence layer on top of existing research infrastructure. It does not replace your analysts, your models, or your terminals. It tells them what changed in the filing universe that nobody else has noticed.
Three Sector Studies · Financials (37) · Healthcare (34) · Diversified (185)
Cross-Sector Replication and New Signals
The earnings prediction signal (LM sentiment) replicates across all three studies: IC=-0.103 (financials), -0.100 (healthcare), -0.090 (diversified). Same mechanism, same direction, same magnitude. All survive Benjamini-Hochberg correction. The combination study added balance sheet prediction: NLP now predicts ROA changes one quarter ahead (IC=+0.120 OOS financials, +0.190 OOS diversified), surviving all macro controls at t=+4.77.
Haiku adds orthogonal balance sheet prediction.
Claude Haiku confidence predicts ROA changes OOS in all three studies (financials +0.332, healthcare +0.295, diversified +0.081). The anti-overfitting signature is consistent: IS near zero in all three, OOS positive and significant. In healthcare, the H11 transcript-filing gap was confirmed with the opposite mechanism: optimistic call relative to filing predicts positive surprise (pipeline confidence), while in financials the same divergence is bearish (overconfidence).
First, the financial sector (37 companies) has uniquely comparable disclosure structures. Banks competing with banks, insurers with insurers. Peer-relative signals are cleaner when peers face identical disclosure requirements. The Haiku-LM combination reaches IC=+0.296 with near-zero correlation (+0.027).
Second, the healthcare sector (34 companies) tests whether signals transfer across different disclosure cultures. They do, with important differences: managed care signals flip direction, large pharma forward-looking ratio is a standalone signal (IC=+0.350), and the transcript-filing gap operates with the opposite mechanism (pipeline confidence rather than overconfidence).
Third, the diversified universe (185 companies, 9 GICS sectors) tests scale. Panel fixed effects fail cross-sector (p=0.987), confirming sector homogeneity matters. But the LM signal still holds at IC=-0.090 (BH p=0.004), and the accruals interaction is strongest here (3x signal in high-accruals companies, 6/8 years walk-forward confirmed).
H11: Call vs. Filing Divergence Predicts Returns
When bank management sounds more optimistic on the earnings call than their most recent annual filing suggests, the stock underperforms. This gap, between what management writes in regulated filings and says in public calls, is measurable and persistent.

H9: Peer-Relative Optimism Predicts Underperformance
When a bank’s management tone on the earnings call is more optimistic than peer-group median at the same moment, controlling for the macro environment all banks face simultaneously, the stock underperforms at the 180-day horizon. The signal is stronger in the 17-bank universe than in the original broad-market study.

H2: Filing Sentiment Drift Strongest for Canadian Banks
The MD&A sentiment drift signal, confirmed in the original study, holds across all 37 financial sector companies, but with meaningful subgroup variation. Canadian banks and P&C insurers drive the strongest signal. US regional banks show near-zero IC, consistent with more formulaic disclosure practices.

The financial sector findings are based on 37 companies tested over 2015-2025. Healthcare uses 34 companies, diversified uses 185. The H11 and H9 banking signals use 17 companies. ROA prediction survives all macro controls in financials (t=+4.77) but not in other studies. Healthcare Haiku trend weakens 2022-2025. Combined signal discovered OOS, not pre-specified. Nothing here constitutes investment advice.
