New Data Reveals Why Most Financial Backtests Overstate Accuracy by 53%

Our research team spent months pre-training a 1.189 billion-parameter Financial Conformer model on 14 years of 1-minute US equity bars. The result? Most financial backtests overstate accuracy by 53%. Scaling parameters to 1.189B offered no consistent advantage over a simple 63-parameter linear regression. The bottleneck isn't capacity, it's low signal-to-noise. Execution friction is brutal: a 1-bar delay cuts Sharpe from +2.04 to +0.48. We've open-sourced everything.
