Screening Stocks for Seven-Day Weakness and Positive Institutional Flows

Summary

This Chinese-language article proposes a stock screen combining a turnover-rate band of 3% to 12%, a seven-session decline condition, and positive institutional buying or net flow. Its premise is that institutional demand during a decline may provide support and signal potential rebound interest. It offers both a platform formula and a Python example, with the latter checking current turnover, a seven-day closing-price low condition, and positive summed net amounts over five sessions.

The article characterizes the idea as suited to short-term trading and warns that market-wide noise can distort the signal, institutional buying alone is insufficient for long-term decisions, and company fundamentals and risk diversification should also be considered. The formula and narrative are not fully aligned: the stated seven consecutive down days are not directly verified by the shown low-of-seven condition, which only checks whether the latest close is the lowest in the window. No backtest results or performance evidence are supplied, and data-field definitions may need adjustment across sources.

Key ideas

• The proposed screen combines a turnover-rate range, recent price weakness, and positive institutional net buying.
• The article provides formula and Python examples, though their flow lookback and price condition are not identical to the narrative.
• A seven-day low condition does not by itself establish seven consecutive declining sessions.
• The author warns about market noise and recommends adding fundamental analysis, risk controls, and diversification.
• No backtest results are provided to establish the strategy’s profitability.
