Screening Shanghai-Listed Stocks by Recent Gain and Trading Activity

Summary

The post describes an equity screen that ranks stocks by a capital-strength measure, with turnover and volume ratio given as examples, and filters for a positive 10-day return below 35%. It also specifies stocks whose codes begin with 60, which identifies a stock-code group rather than a 60-day lookback. The post’s explanation confusingly describes that condition as selecting stocks within 60 days, so readers should distinguish the stated code prefix from the accompanying interpretation.

The author argues that activity measures may help identify stocks with stronger capital flows and that a bounded recent return can avoid selecting names after a very large rise. These are proposed screening rationales, not demonstrated results: the page provides no tested selection expression, backtest, benchmark, or return evidence. It notes that flow indicators and short horizons can mislead, and suggests adding other activity measures, changing the time window, or including technical indicators.

Key ideas

• The screen combines a positive 10-day return below 35% with a stock-code prefix beginning with 60.
• Turnover and volume ratio are proposed as measures of trading activity or capital strength.
• The post mischaracterizes the 60 code prefix as a 60-day period, so its wording requires care.
• No backtest or performance evidence is supplied, and short-term activity and return filters may be unreliable.
