Screening Chinese Stocks by Prior-Day Range, Leaderboard Presence, and Limit Status

Summary

This stock-selection idea combines three prior-day conditions: price amplitude above 1%, appearance on a trading leaderboard, and no limit-up close. The text interprets a larger range as a sign of short-term volatility and leaderboard presence as a possible indication of trading interest. It provides example formula and Python-style implementations for combining the conditions and sorting the resulting candidates. The implementation examples reference Chinese market data and limit rules.

The post cautions that simulated backtest outcomes may differ from live results, leaderboard stocks can have volatile sentiment, and the simple filter may produce noise or false signals. It suggests adding valuation measures, adjusting how limit-up status is defined, and applying risk controls. These are suggestions rather than tested improvements: the document gives no performance statistics, sample period, benchmark, or detailed portfolio and execution rules. The screen identifies candidates; it does not establish that they will rise or that the approach is profitable.

Key ideas

• The screen selects stocks with a prior-day amplitude above 1%, leaderboard presence, and no prior-day limit-up close.
• The article treats range and leaderboard activity as signs of volatility and possible short-term interest.
• It illustrates combining the conditions with formula and Python-style examples using Chinese market data.
• The author warns that backtests may differ from live performance and that the screen may create noisy signals.
• Suggested extensions include valuation filters, adjusted limit-status definitions, and risk controls.
