A Stock Screen Combining Turnover, Float Size, and Weekly MACD

Summary

This Chinese equity screening example combines a turnover band, a maximum circulating share count, and weekly MACD above its zero line. The intended rationale is to focus on relatively active, smaller-float stocks whose trend indicator is positive. The post suggests adding other technical measures, such as RSI or KDJ, and fundamental conditions to reduce reliance on a single signal. Its code example calculates MACD and filters a data frame using turnover, circulating market capitalization, and a positive MACD value.

The document provides screening rules and illustrative code, but no backtest, comparison, or measured results. It also shifts between describing a weekly signal and showing code that does not clearly establish weekly aggregation, and its prose and example differ in how the turnover range is bounded. The selection criteria therefore require definition and validation before use. No entry, exit, sizing, or portfolio risk rules are specified.

Key ideas

• The screen combines a turnover range, a float-size ceiling, and MACD above zero.
• A positive weekly MACD is used as a trend filter for lower-float stocks.
• The post recommends adding further technical and fundamental measures to diversify the screening criteria.
• The example supplies no evidence that the filters improve returns.
• Weekly aggregation and turnover boundaries need clarification in an implementation.
