Equity Screen Using Daily Range, Listing Age, and Position Growth

Summary

This Chinese stock-screening proposal selects shares with daily amplitude above a threshold, a minimum time since listing, and a reported daily increase in position share above five percent. It frames high position growth as a possible sign of market interest, while the range and listing-age filters are intended to identify active stocks with some trading history. The article also supplies formulas for amplitude and position share, plus a Python example that queries market data.

The method is a basic filter rather than a tested trading strategy. The author notes that it may overemphasize technical or positioning data and omit company finances and other drivers, recommending additional technical and fundamental checks. The code’s data fields and screening logic are not fully consistent with the prose, and no sample results, backtest, or evidence of predictive value is presented. In particular, position-growth measures and their source need verification before interpreting the screen as an equity signal.

Key ideas

• The screen combines daily price amplitude, listing age, and a daily position-growth ratio.
• The proposal treats rising position share as a possible indicator of market interest, not demonstrated evidence of future gains.
• The author cautions that the filter can omit financial fundamentals and other important factors.
• The provided data fields and code require review, and the document reports no backtest.
