Screening Chinese Stocks by Intraday Flow, Range, and Turnover

Summary

This stock-selection example combines three filters: a daily price range above 1%, afternoon large-order net inflow, and prior-day turnover above 8%. The stated rationale is to find shares with substantial movement, apparent buying support, and recent trading activity. It recommends further fundamental, technical, and policy analysis before treating selected stocks as investments, and identifies overheated or small-cap names and changing market conditions as risks.

The document gives indicator formulas and a Python-style data retrieval example, but these details are not fully consistent with the stated rules. In particular, its code compares today’s trading amount with an earlier day’s amount as a proxy for turnover, rather than directly using the prior-day turnover condition described in the strategy. The afternoon timing of the flow filter is also not clearly represented by the daily data example. No backtest results or evidence of profitability are reported, so this is best read as a screening concept that needs careful data and implementation checks.

Key ideas

• The proposed screen combines a daily range threshold, afternoon large-order net inflow, and prior-day turnover above 8%.
• The rationale is to find volatile stocks with buying activity and recent trading interest.
• The provided data example does not clearly implement the stated prior-day turnover condition.
• The document warns that the screen may select overheated stocks and recommends broader analysis and risk controls.
• No performance test is provided to establish that the screen is profitable.
