EQUITY RISK PREMIUM CUSHION SIMULATOR SG Strategy Framework
Research Grounding: Alain Bokobza (Societe Generale)
Institutional Insight: As observed by Alain Bokobza (SocGen), dramatic upgrades to forward earnings expectations have reinforced the forward equity earnings yield, keeping Equity Risk Premiums (ERP) resilient rather than collapsing into severe negative territory amid the 10-Year sovereign yield spike.

Bokobza Framework Mechanics

The Core Dilemma: Traditional Fed model valuations compute ERP simply as unrevised Earnings Yield minus 10-Year Treasury Yield. At current rate regimes ($4.65\%$), an unrevised $\$245$ EPS delivers only a $4.22\%$ earnings yield, yielding a negative risk premium of $-43\text{ bps}$.

The Bokobza Cushion: As highlighted by Alain Bokobza at Societe Generale, consensus analysts have systematically ratcheted up forward earnings expectations ($+14.5\%$). This expands the numerator to $\$280.53$, pulling the earnings yield up to $4.83\%$ and creating an immediate $+61\text{ bps}$ buffer.

ERP = \frac{\text{Baseline EPS} \times (1 + \text{Rev Rate})}{\text{Index Price}} - Y_{10\text{Y}}

When yields increase by $50\text{ bps}$, equity valuations can remain stable without index multiple compression if forward revision momentum keeps pacing nominal yield growth.
