Screening Stocks for Volatility, Recent Limit-Ups, and Rising Averages

Summary

This Chinese equity screening proposal selects stocks with daily price amplitude above a threshold, at least one limit-up day during the preceding 25 days, and an upwardly diverging moving-average condition. The post interprets these filters as signs of elevated activity, recent market interest, and potential upward momentum. It includes sample indicator and Python-style logic intended to identify candidates for a watchlist.

The author warns that the method relies on technical and historical price data, ignores company fundamentals, and may fail when the broader market is falling. Other stated limitations include the narrow focus on short-term upside and the omission of wider market context. Suggested additions include fundamental and sector analysis, other indicators, market-trend filters, diversification, and stop-loss or profit-taking rules. No returns, comparative evidence, or backtest are reported. The sample formulas and code do not clearly demonstrate that all three stated conditions are correctly evaluated over the intended lookback, so their implementation would need checking before use.

Key ideas

• The proposed screen combines price amplitude, a recent limit-up event, and an upward moving-average condition.
• The lookback for the limit-up event is the preceding 25 days.
• The post treats these conditions as proxies for activity, market interest, and upward momentum.
• The method omits fundamentals and broad-market conditions, which may weaken it during market declines.
• The examples provide no performance evidence, and their implementation should be checked against the intended rules.
