SOPHRON
Market regimes
How growth, inflation, liquidity and policy regimes reshape relative-value and risk premia.
Evidence, made legible.
Selected thinking on global market regimes, liquidity, portfolio construction and the risks hidden inside familiar assumptions.
Research direction
Notes that clarify judgment—not marketing claims.
Sophron publishes selected research to show how evidence is framed: what regime is assumed, what would invalidate the thesis, and where liquidity or concentration can turn a familiar idea into a fragile one.
These materials are informational. They are not recommendations, offers or representations of current products.
Theme map
Where the research spends its time.
Portfolio fragility
Hidden correlations, crowded exposures and the conditions under which “diversification” fails.
Liquidity & credit
Carry, duration and credit selection when funding conditions and market depth deteriorate.

Selected notes
Latest published thinking.
Signal Decay and the Cadence of Model Refresh

Most “AI quant” failures start in messy data, not in the neural net. How Sophron sequences features, labels and leakage checks.
Backtest Honesty in an Age of Easy Overfitting
Walk-forward tests, multiple-testing risk and the institutional habit of distrusting a perfect equity curve.

Why traditional diversification can fail when regimes change — and how Sophron designs for fragility.
Execution Costs Are Part of the Signal
Slippage, timing and market impact turn paper alpha into live disappointment—how systematic books should budget for reality.
Cross-Sectional Risk Budgets for Quant Books
