A-Share Stock Selection Using Analyst Consensus Estimate Revisions
Summary
This research summary discusses stock-selection factors built from analyst consensus estimates for Chinese A-shares. It notes that analyst estimates provide information beyond company financial statements and trading data, while also warning that estimates can be systematically optimistic and often focus on annual reporting figures. Simply using consensus levels may therefore add little. The study instead constructs factors from changes in forecast EPS, the proportion of EPS revisions upward, changes in forecast price-to-earnings ratios, and earnings surprises.
The summary reports that these individual factors retained stock-selection ability after controlling for market capitalization and industry exposure. It also describes a combined consensus factor that reportedly remained effective after accounting for those exposures and common style risks. The stated evidence is an average information coefficient above four percent in the CSI 300, CSI 500, and broad CSI universe. The underlying report is not reproduced here, so factor definitions, sample period, implementation details, costs, and other validation results cannot be assessed from this summary alone.
