Screening for Volatile A-Shares with Prior-Day Leaderboard and Reversal Signals

Summary

This Chinese stock-selection proposal looks for shares with amplitude above 1, a prior-day appearance on the trading leaderboard, and a pattern described as an engulfing or reversal move. The rationale is that a wide range may signal short-term opportunity, leaderboard activity may reflect heightened attention, and a reversal pattern may indicate a change in sentiment. The article provides illustrative formula and Python examples that combine the three conditions. It does not report a backtest, sample outcomes, or evidence that these signals forecast returns.

The author cautions that high-amplitude shares carry greater volatility, leaderboard appearances are incomplete measures of overall stock behavior, and reversal patterns can fail. Suggested additions include moving averages, valuation or financial measures, fund-flow and sector data, and industry constraints. The pattern definition in the example code is unusual: it checks a prior bullish candle and a current high below the previous low, which may not match common uses of “engulfing” or “reversal.” The meaning and time basis of the amplitude threshold should also be specified before implementation.

Key ideas

• The proposed screen intersects an amplitude condition, a prior-day leaderboard appearance, and a reversal pattern.
• The author treats leaderboard activity as a possible signal of short-term attention, not definitive evidence.
• High volatility and false reversal signals are identified as risks.
• The sample reversal condition may not align with common chart-pattern definitions.
• The article presents no performance results.
