Chinese Stock Screen Using Price Amplitude, Year, and Float Shares

Summary

This document describes a Chinese stock screening rule combining daily price amplitude, a calendar-year condition, and a maximum number of circulating shares. It explains that the amplitude filter is intended to find more volatile stocks and that a smaller float may make a stock more susceptible to capital flows. The rule is also expressed as a screening formula and a Python-style data filter.

The post offers no backtest, performance evidence, or details on how selected stocks would be traded. Its discussion of choosing stocks from 2021 as potentially strong under current market conditions is not supported with data, and the stated amplitude calculation differs between the formula and the Python example. It notes that small floats can reduce liquidity and that high amplitude raises risk, and suggests adding industry comparisons and fundamental measures. These filters alone do not establish investment value or a workable trading strategy.

Key ideas

• The screen combines a daily amplitude threshold with a calendar-year filter and a circulating-share limit.
• The post associates high amplitude with greater volatility and small floats with increased sensitivity to capital flows.
• It warns that low-float stocks may be difficult to sell and that volatile stocks require risk controls.
• The post suggests comparing float sizes within industries and adding fundamental indicators.
• The document provides no backtest or evidence that the screening rule produces profitable trades.
