Daily Trading & Release Archive

Day-by-day out-of-sample trading results, pre-registered signal books, and live-readiness stress audits across CryptoFactors and EMFactorTiming.

Unified monorepo architecture

One codebase. Eight studies.
Shared statistical rigor.

All eight projects are consolidated in the open-economic-quant monorepo, sharing a core econometric & portfolio engine (oeq-core v0.2.0) and automated CI verification.

Layer 01 · Shared Engine

oeq-core v0.2.0 Infrastructure

Centralized statistical and portfolio primitives imported across subprojects with 100% unit-test coverage:

  • Shrinkage & Covariance: Empirical Bayes adaptive cross-sectional shrinkage & Ledoit-Wolf covariance regularization.
  • Inference & Multiple Testing: Newey-West HAC t-statistics, Politis-Romano stationary bootstrap, White Reality Check, and Deflated Sharpe Ratio (DSR).
  • Execution Shortfall: Turnover-damped weights, break-even fee solvers, and Almgren-Chriss square-root market impact.
Layer 03 · Live Verification

Automated Sync & Stress Audits

Every update runs verify_monorepo.py and sync_ecosystem.py across GitHub and Hugging Face:

  • 4-Part Live-Readiness Audit: Execution delay (0m / 1m / 5m / 1h / 24h), realistic 24-perp short hedge with 8h funding, capacity stress ($10k–$5M), and pre-trade bad-print guards.
  • Public Reproducibility: Pinned HF Dataset (917 files) & HF Space.

Each column reports the net return realized on that UTC day from signals formed at the prior 00:00 UTC close (net of 10 bp round-trip cost for single factors and 15 bp weekly rebalance cost for Product B, including 8h perpetual funding accrual). During the Oct 22–25 deleveraging sell-off (Big-24 EW −7.70%), Low-Price Range gained +7.73% over four consecutive positive days and Product B Beta-Hedged gained +1.52% on the Oct 22 crash day; during the Oct 26–27 short squeeze, Taker Buy / Large-Trade OFI and High-Volume Reversal led.

Selected research

Eight questions, with the evidence in view.

Experiments & incentives

Who should get the offer?

The complex targeting model has not earned its advantage.

I test effect estimates against known answers, then compare spending rules at the same budget in simulated markets held out from training.

Read the study & evidence →
Forecasting & information

Would the forecast work in real time?

Changing the data vintage changes which models look best.

I reconstruct official release histories and rerun forecasts with three information rules: data known then, revised values with the same availability, and unrestricted latest values.

Read the study & evidence →
Trade & public policy

Who absorbed the tariff?

The evidence points toward higher costs for U.S. importers.

I compare each wave of tariffed products with never-tariffed products, tracking unit import values before and after the policy and checking three sample windows.
