Analyzing WorldQuant Alpha#100 as an Equity Factor

Summary

This tutorial demonstrates a workflow for evaluating WorldQuant Alpha#100 on Chinese equities. It builds the factor from price and volume signals, including the close’s position within the daily range, the relationship between closing price and ranked average turnover, and the timing of a 30-day low. The construction applies industry adjustments and scales components before combining them with a turnover ratio. The example uses the CSI 500 as its benchmark and describes filtering out special-treatment stocks, recent listings, suspended securities, and non-mainland listings.

The analysis framework winsorizes and standardizes factor values, then neutralizes them by industry and log market capitalization. It forms daily quantile portfolios and calculates forward returns using next-day open entry and the following day’s open exit, alongside benchmark comparisons, performance statistics, and information coefficients. The document provides implementation details and a factor submission workflow, but reports no actual performance results. Its conclusions therefore depend on running the analysis; the stated universe, data filters, holding convention, and benchmark constrain how any results should be interpreted.

Key ideas

• Alpha#100 combines price-range and turnover-related signals with a volume-to-average-turnover adjustment.
• The example neutralizes factor values by industry and log market capitalization after clipping and standardizing them.
• Daily quantile portfolios are evaluated using a next-open entry and subsequent-open exit convention.
• The workflow calculates benchmark-relative performance and information coefficients but supplies no results in the document.
• Universe selection, security filters, and benchmark choice shape the interpretation of the analysis.
