Strategy in a nutshell

Invest in U.S. stocks based on top 2% production complementor returns. Go long high-return complementor stocks and short low-return peers. Value-weighted portfolio rebalanced monthly with six-month formation gap.

Economic rationale

Delayed attention to production complementors’ fundamentals creates return spillovers. Investors’ inattention, stronger economic linkages, and higher arbitrage risk drive predictable momentum effects across connected firms.
