证据摘录
- “We propose OLIVIA, a protocol for such tests: point-in-time inputs with company identities masked, selection on validation data only, an analysis plan frozen by cryptographic hash, and a test period unblinded once through a logged lock.”
- “The fine-tuned model's signal replicated on two validation quarters (daily information coefficients 0.055 and 0.065) but fell to 0.020 (t = 1.7) on the blinded January-July 2026 test.”
- “No model can tell over- from under-reaction, and no pre-registered strategy survives costs and a deflated Sharpe ratio.”
