Screening Shanghai-Listed Stocks by Range and Lower Daily Lows

Summary

The screen selects stocks with codes beginning with 60, a daily high-to-low range exceeding one percent of the opening price, and a current low below the prior day’s low. The article describes this as a short-term selection rule and provides corresponding indicator-formula and Python-style examples. It also mentions sorting candidates by turnover, though the implementation details and data handling are not fully explained in the text.

The rationale offered is that a larger intraday range may indicate volatility, while a lower daily low may identify a stock with further downside or short-term swing potential. The article cautions that the lower-low condition alone is not enough to assess investment merit and suggests combining it with indicators such as volume or RSI, as well as company fundamentals and market themes. No backtest, trading rules for entries or exits, transaction-cost analysis, or results are supplied, so the screen should not be treated as evidence of profitability.

Key ideas

• The screen filters for 60-prefix stock codes, a daily range above one percent of the open, and a low below the prior day’s low.
• The article frames the conditions as a short-term stock-selection rule.
• The examples sort qualifying names by turnover.
• The author warns that a lower daily low alone does not establish investment value.
• Suggested refinements include additional indicators and fundamental or market context.
