Chinese Stock Screen for Large Prior Turnover and a Sharp Daily Decline

Summary

This stock-selection note proposes screening for shares with an intraday range above 1, a maximum daily decline between 4% and 5%, and prior-day trading value above 60 million. Its stated approach relies on current price movement and trading activity, without adding a broader market or company-quality model. The included formula and Python example are presented as references, but the Python conditions do not transparently reproduce every stated filter, so implementation details may differ from the prose.

The author characterizes the screen as simple and speculative, with short-term orientation and substantial risk. It specifically notes that the logic omits financial statements and competitive position, and suggests adding financial and other indicators while balancing short-term activity with longer-term allocation. The document offers no backtest, performance statistics, or evidence that the selected stocks rebound after falling; it should be read as a screening idea rather than an established trading strategy.

Key ideas

• The screen combines a daily price-range threshold, a sharp decline band, and a prior-day turnover-value threshold.
• Its selection logic focuses on short-term price action and trading activity.
• The note warns that it ignores financial condition and may be speculative and risky.
• The code is illustrative and does not clearly encode every filter described in the text.
