Cross-Sectional Ranking of a Four-Bar Price Direction Signal

Summary

This document gives a single daily factor example for Chinese stocks. It forms a price proxy by weighting the open and high, compares that proxy with its value four bars earlier, and takes the sign of the difference. The resulting direction signal is ranked by date across instruments and multiplied by negative one, so stocks with lower rather than higher ranked signals receive larger factor values.

The material is only a factor construction example. It provides no portfolio rules, trading rationale, backtest results, or discussion of turnover, costs, and risk. It also refers to a backtest graphic and strategy source that are not present in the supplied text, and notes a required platform environment. The example therefore shows how a cross-sectional signal can be expressed, but does not establish whether it predicts returns or how it should be used in a trading system.

Key ideas

• A weighted combination of daily open and high prices serves as the input price series.
• The signal captures the sign of the price proxy's change over four bars.
• The signal is ranked across stocks for each date and inverted.
• The document provides no performance evidence or complete portfolio implementation.
