Institutional-style macro and cross-asset briefing generated from the Bayesian market stack.
1. Executive summary
What matters today
- Global equities remain under pressure: S&P 500 is down +9.51% over one month with a 13% risk-off posterior.
- Growth leadership is still absent: Nasdaq daily move was +0.89% and model volatility is 22.9% annualized.
- USD/KRW strengthened to 1,472.98, up -2.40% on the month, reinforcing a tighter external backdrop for Korean risk assets.
- Rates are still the macro stress point: the U.S. 10-year yield sits at 4.39% with Moderate vol conditions.
- Near-term Bayesian forecast stays defensive: SPX ▲, US10Y ▼, Gold ▼, USD/KRW ▼, Oil ▼.
- Single-name opportunity remains selective rather than broad: top-ranked long is QQQ with score 0.849 and 75.0% 20-day upside probability.
House view
The macro tape still favors selective exposure over broad beta. Risk-off probabilities remain elevated across equities and rates, while FX pressure and high rates volatility keep the overall regime restrictive.
2. Visual dashboard
The matrix above is the fastest read on the system: posterior regime conviction is still skewed toward defense, while current volatility remains too elevated to support a clean risk-on chase.

7. Digital assets
Bitcoin trades at 77,089.00, Ethereum at 2,278.48, and the sentiment gauge reads 26 (Fear). That keeps crypto tactical rather than strategic.
8. Bottom line
This is still a preservation-first tape. The sellable setup is not broad bullishness but disciplined selection: keep duration of conviction short, prefer names with strong posterior upside and contained volatility, and treat macro rallies as tactical until rates and FX stress materially cool.
Methodology: Bayesian regime switching, stochastic volatility filters, Bayesian VAR, and a cross-sectional stock-scoring model.
