Chinese Stock Screen Using Turnover, Seven-Day Weakness, and Limit-Down Signals

Summary

This Chinese stock-selection post proposes screening for shares with turnover between 3% and 12%, recent price weakness, and a prior-day 9:15 matching price described as limit-down. The stated rationale is to find potentially oversold stocks that might rebound. It also suggests adding valuation measures such as price-to-earnings and price-to-book ratios to account for company fundamentals, then checking the strategy with additional calculations and technical analysis.

The post warns that market noise can affect the signal, that falling prices may reflect poor fundamentals rather than overselling, and that a limit-down indication does not establish future direction. Its formula and Python example use a seven-period lowest-close condition and a prior high-to-low comparison; these do not clearly implement seven consecutive down days or the 9:15 matching-price description. No backtest results or evidence of profitability are provided, so the screen should be treated as an unvalidated selection idea.

Key ideas

• The proposed screen combines turnover in a stated range with recent price weakness and a prior-day limit-down-related signal.
• The post frames the setup as a possible way to identify oversold shares with rebound potential.
• It recommends adding valuation measures to consider company fundamentals.
• The author warns that market noise and deteriorating fundamentals can make falling prices misleading.
• The supplied formula does not clearly match every element of the prose description, and no performance evidence is shown.
