Screening Chinese Stocks by Intraday Range and Prior Main-Fund Flow

Summary

This stock screen combines three filters: a daily high-to-low range above 1% of the previous close, a ticker beginning with 60, and a prior-day main-fund flow condition. The accompanying indicator formula and Python example express the flow condition as a negative net inflow, despite the prose describing the stock as controlled or favored by major investors. That inconsistency makes the intended signal unclear.

The document treats a large range as a sign of higher volatility and the ticker prefix as a way to identify a particular market segment. It warns that volatile stocks may not perform well and that relying on one day of fund-flow data can miss broader market conditions. It suggests adding price performance, turnover, or fundamental measures, but provides no backtest or outcome data to establish that the screen is useful.

Key ideas

• The screen requires a daily range greater than 1% of the previous close.
• It restricts eligible tickers to those beginning with 60.
• The formula and example use negative main-fund net flow, which conflicts with the prose description.
• The document cautions that high volatility and a single day of fund flow are insufficient grounds for judging a stock.
