Hypothesis Tested: Substance without an audience
By Artul.ai Research Group · n = 97 earnings calls · First published 2026-08-28
Some earnings calls deliver real substance — specific numbers, candid discussion, concrete guidance — but almost nobody seems to be listening: low analyst engagement, thin coverage, no audience. This study isolates that pattern, "substance without an audience," among 97 calls out of a corpus of 165,000 earnings-call transcripts that an AI read and scored against the same battery of questions. For anyone who follows calls closely, it asks a simple question: does good disclosure matter if the market isn't watching?
The group's calls score high on specificity (7.67 vs 7.65) and candor (6.79 vs 6.94), yet they co-occur strongly with calls that read rehearsed (1.31x lift, 50.5% vs 38.6%) and with "volume about to step up" (1.35x). They rarely appear alongside "results worse than direction" (0.59x) or "the hidden segment" (0.57x). Guidance tells a clearer story: only 3.1% lowered guidance versus 12.9% in the base. The pattern is also rare and spiky by year — 0.03 in 2015, near zero in 2020, a peak of 0.12 in 2022, and 0.02 in 2024.
Honest limits apply. The AI-read fields are noisy single-model judgments, and the co-occurrence lifts are descriptive, not causal. Any return statistics here are historical descriptions of a 22,449-call sample, not a trading signal — our own forward tests falsified directional prediction outright. Language models also partially remember famous stocks' histories, which contaminates any backtest built on their outputs. Treat this as a pattern observation, not an edge.
