Sector Analysis

Does the NLP signal vary across sectors? Short answer: dramatically. Energy IC = +0.31 vs Technology IC ≈ 0. Consistent with efficient market theory by sector.

Key insights

Deploy selectively by sector

Why it matters

Top signal is — while weakest is —.

Build sector-aware position sizing rather than a uniform cross-sector model.

Technology signal is near efficient-market floor

Why it matters

Narrative-heavy guidance in large-cap tech is rapidly priced by the market.

Lower expected alpha; keep tech weight capped unless supported by non-NLP factors.

Energy and Industrials behave as information-asymmetric sectors

Why it matters

Operational disclosures remain concrete and slower to be fully priced.

Prioritize NLP feature depth and earnings-event workflows in those sectors.

Conclusion: alpha is concentrated in a few sectors, not evenly distributed
Primary question: where should NLP-driven capital be concentrated?
