Stock Screening with Recent Price Spikes, Size, and Fundamentals

Summary

This proposed stock screen begins with price and size conditions: amplitude above one, at least one daily gain of 10% or more in the prior 25 trading days, and a circulating market value above 10 billion yuan. Its refined version adds positive operating cash flow, return on equity above 10%, positive year-over-year revenue growth, and a promise-fulfillment rate above 70%. A ranking step based on heat is also referenced.

The article explains that recent sharp gains can indicate momentum but may also reflect risky hot sectors; its size threshold may exclude smaller companies, and the initial rules may miss other candidates. It suggests adding fundamentals and industry context. Formula and sample-code references illustrate the conditions, but the document provides no backtest or return evidence. Some formula references do not cleanly match the stated prose—for example, a revenue-growth test uses a threshold above negative one—so users would need to resolve implementation details before relying on the screen.

Key ideas

• The initial screen selects for large daily amplitude, a recent daily gain of at least 10%, and market value above 10 billion yuan.
• The refined rules add positive cash flow, return on equity above 10%, revenue growth, and promise fulfillment above 70%.
• Recent sharp gains can expose a screen to speculative sector risk, while a high size threshold may exclude smaller firms.
• The sample formulas contain discrepancies with the written rules, and no performance test is reported.
