Combining Relative Volume, Positive Earnings, and Recent Limit-Up Activity

Summary

This note proposes a Chinese equity screen combining high relative trading volume, positive price-to-earnings values, and at least two limit-up sessions within a 500-day lookback. It describes ranking by relative volume and presents the three conditions as signals of trading interest, profitability, and past activity. The article also suggests adding market capitalization, industry, technical indicators, and broader market context.

No historical test, return series, or evidence of predictive value is supplied. The stated risks include possible distortion in volume measures, valuation ambiguity, and mismatch with an investor’s risk tolerance. The example data definitions are unreliable: it describes PE using a stock’s price divided by its average price, which is not the standard earnings-based ratio, and the code excerpt is incomplete. The screen is therefore best read as a set of proposed filters, not a validated strategy; its data fields and definitions would need correction before evaluation.

Key ideas

• The proposed screen combines relative volume ranking, positive PE, and repeated limit-up events.
• The lookback for limit-up activity is 500 days, with a minimum of two occurrences.
• The article suggests adding size, industry, technical, and market-context filters.
• It provides no performance test, and its PE definition is inaccurate.
