Screening Stocks for Repeated Limit-Ups, Low Prices, and Amplitude

Summary

This document describes a short-term Chinese equity screen using three conditions: a share price below 12, more than two limit-up sessions within ten days, and amplitude above one. It frames repeated limit-ups as a possible sign of continued upside and presents a ranking idea based on volatility. Example implementations are mentioned for a screening formula and a Python workflow that counts recent daily percentage gains and checks the latest low price.

The article warns that repeated limit-ups do not ensure further gains, and that short-term rumors, information gaps, and broad market conditions can distort signals. It suggests adding fundamental or valuation filters, making the screening criteria more comparable through weighting, and refining the timing and distribution of limit-up events. The document supplies no backtest, transaction costs, or performance statistics, and its code example does not visibly apply every stated condition consistently: the amplitude criterion is absent from the shown selection logic. The screen should therefore be treated as a speculative selection heuristic rather than a validated strategy.

Key ideas

• The screen looks for stocks priced below 12 with more than two limit-up days in a ten-day window and amplitude above one.
• The rationale is that repeated limit-ups may reflect short-term momentum, but do not guarantee continued gains.
• The article identifies market conditions, rumors, and information asymmetry as risks to this short-horizon approach.
• It proposes adding fundamental or valuation constraints and refining how the criteria are weighted and timed.
• The code example omits the stated amplitude condition, and the document provides no performance evaluation.
