Strategy in a nutshell

Chinese A-shares (non-financial, Shanghai/Shenzhen) are ranked monthly by residual news-connected-firm (RNCF) returns, which measure peers’ news-driven returns orthogonalized to the focal stock. Long the top quintile, short the bottom. Value-weighted and held one month.

Economic rationale

Investors underreact to value-relevant news from peer firms, creating cross-firm return predictability. Joint news coverage reflects editorial decisions and shared fundamentals, highlighting economic linkages in China’s stock market beyond momentum spillovers.
