A Short-Term Stock Screen for Large Intraday Declines

Summary

The document describes a Chinese stock screen combining price range, large-order net volume ranking, and a daily maximum decline bounded between 4% and 5%. The rationale is to identify stocks under short-term pressure that might rebound, with a ranking based on recent large-order activity. It also references example filters for excluding special-treatment or suspended stocks, applying a liquidity threshold, sorting by recent returns, and selecting a small group.

The post presents this as a potential entry screen, not a validated strategy. It supplies no performance study or evidence that stocks in this decline band reliably recover. Its own caveats are that short-term price and volume indicators omit company fundamentals, industry conditions, and longer-term trends, and an expected rebound may not occur. The accompanying code examples are inconsistent in their fields and conditions, so they do not define a reliable, directly reproducible implementation. The article recommends combining technical screening with fundamental and broader market analysis.

Key ideas

• The proposed screen combines price amplitude, large-order activity, and a bounded daily decline.
• The rationale is to look for pressured stocks that may rebound.
• The post provides no backtest or evidence that the decline band predicts reversals.
• The code examples contain inconsistencies, and the screen omits fundamental and industry analysis.
