This section provides a brief overview of the key arguments. You do not need to read the full detailed report below.

✅ Key PRO arguments:

1. ■Publicly disclosed systematic signals keep earning when their returns rest on durable risk and implementation constraints. A signal's return is either a transfer from counterparties who are being fooled or compensation for a constraint someone else must bear; knowledge of the rule does not dissolve the constraint.
2. ■The negative's mechanism that disclosure inevitably degrades signals through arbitrage and capacity presupposes that a signal's return is a rent extracted from an exploitable mispricing. In the formal literature, arbitrage is a property defined relative to an admissible class of strategies, and the negative's own taxonomy concedes the cell that breaks its argument.

❌ Key ANTI arguments:

1. ■Public disclosure inevitably degrades systematic signal effectiveness through arbitrage and capacity constraints. The affirmative commits a substitution error by measuring persistence of macro/structural properties such as CAPE or multifractal order-book correlations and then concluding these support trading signal effectiveness, without providing the transfer operator linking those observations to net-of-cost, risk-adjusted returns.
2. ■The effectiveness of a signal is not an intrinsic property of the rule itself, but a measure of the net alpha available to an agent after competing for that edge. The affirmative's reliance on theoretical conditions for the absence of arbitrage, such as the existence of a local martingale, is a category error.

💭 Conclusion: False. The winning negative argument establishes that public disclosure degrades systematic signal effectiveness through arbitrage and capacity constraints, because a signal's effectiveness is not an intrinsic property but the net alpha available after competing for the edge. The affirmative's defense relies on durable risk and implementation constraints, yet fails to provide the transfer operator linking macro-structural persistence to net-of-cost risk-adjusted returns. The negative also correctly identifies the affirmative's reliance on theoretical no-arbitrage conditions as a category error. The judge sided with the negative at 87% confidence, and the confidence-weighted score for FALSE was 0.87 versus 0.00 for TRUE. Therefore the assertion that effectiveness is not compromised by public disclosure is rejected.

📋 PRO Facts:
• The affirmative defines systematic trading signals as decision rules whose edge comes from repeatable statistical structure or a durable economic constraint.
• The affirmative argues a signal's return is either a transfer from counterparties being fooled or compensation for a constraint someone else must bear.
• The affirmative cites formal literature where arbitrage is defined relative to an admissible class of strategies.

📋 ANTI Facts:
• The negative argues public disclosure degrades effectiveness through arbitrage and capacity constraints.
• The negative claims the affirmative substitutes persistence of macro/structural properties, such as CAPE and multifractal order-book correlations, for evidence of trading signal effectiveness.
• The negative asserts effectiveness is net alpha available after competing for the edge, not an intrinsic property of the rule.

The following financial data tables were referenced during the debate exchanges:

Legend: Peer-reviewed / preprint studies used above, ordered by publication year. Columns give the tested object, the market and data frequency, and the qualitative persistence finding; no return figures are reported because none were computed here. Locators are the preprint identifiers cited in the text.

Legend: Qualitative assessment of signal degradation based on the affirmative's own distinction between "disclosure-resistant" and "attenuated" slices.

Legend: Records consulted to test the negative's arbitrage-and-capacity mechanism, ordered by relevance to the two channels named. Periods as reported by each study; the first three rows are empirical, the last two are definitional and are used only for what "arbitrage" means, not for any return claim. No return figures are asserted here because none were computed.
