Hiring Data as an Equity Signal: Factor Tests and Event Returns

Summary

The supplied summary describes research on alternative data and a hiring-count signal for Chinese equities. It says overseas use of alternative data is still developing, with most applications aimed at short-term opportunities, and identifies six characteristics for assessing data quality. The document itself is presented under a title about classifying industry-themed mutual funds, but the available text does not explain that topic; its substantive summary instead discusses alternative data and recruitment activity.

The hiring-count factor reportedly performed well in backtests from 2017 to 2021. Data preprocessing and filters on counted job postings are said to improve results. The factor has some relationship to common style factors, including size and industry, while the effect of orthogonalization remains unresolved. A separate event test treats a sharp increase in hiring as a signal and reports excess returns around the event versus an equal-weighted CSI 800 benchmark, with larger thresholds associated with stronger excess returns. These are historical claims only: no detailed methodology, performance figures, transaction costs, or robustness analysis is included in the supplied text. The summary cautions that market, policy, and economic changes can invalidate the findings, and that third-party data may contain errors or become unavailable.

Key ideas

• The supplied summary says alternative data is used more for short-term opportunity seeking than for long-term investing.
• Hiring-count signals reportedly performed well in historical tests covering 2017 to 2021.
• Preprocessing and filters on job postings are described as ways to improve the hiring-count factor.
• The hiring signal has some correlation with size and industry factors, while the effect of orthogonalization remains uncertain.
• Sharp increases in hiring reportedly coincided with excess returns relative to an equal-weighted CSI 800 benchmark.
