A Short-Term Stock Screen Using Range, Five-Day Highs, and Buying Activity

Summary

This China-market stock screen combines price movement, a five-day price condition, and a measure described as today’s increase in holdings. It selects non-ST stocks with an amplitude above 1, whose close equals the rolling five-day closing high, and whose calculated increase ratio exceeds 5%. The article frames the five-day condition as seeking stocks with an overall rising tendency and treats high increase ratios as a sign of buying interest. It suggests adding market position, financial condition, or trading volume as further filters.

The article gives example Python screening logic but no backtest, return series, or evidence that the selection rules produce an edge. Its code calculates amplitude in price units, then derives the increase ratio from price change and share counts; those calculations may not match the stated concepts or be comparable across stocks. The article itself cautions that high reported buying activity does not guarantee sound fundamentals or prospects and recommends risk management. The method is therefore a screening recipe rather than a tested trading system.

Key ideas

• The screen combines non-ST status, a price amplitude threshold, a five-day closing high, and an increase-ratio threshold.
• The five-day high condition is intended to identify stocks with rising short-term price behavior.
• The article interprets a high increase ratio as buying interest but acknowledges that it does not establish business quality.
• The example provides no backtest evidence, and its ratio calculations may not faithfully measure the stated concepts.
