Screening Chinese Equities with Positive MACD and a Sharp Daily Decline

Summary

This short strategy note describes a daily pre-open screen for Chinese equities. It selects stocks with MACD above zero, positive trailing price-to-earnings, and a reported intraday low between 4% and 5% below the previous close. The rationale combines a positive trend indicator and positive earnings valuation with a substantial price decline, then ranks candidates by trading volume. The note includes indicator formulas and example snippets for expressing the filter, but it does not provide a historical backtest, trade rules, or evidence that the combination produces positive returns.

The author warns that screening data may not match actual conditions, price-based selection can introduce bias, and sharply declining shares may carry greater risk. It also suggests adding other technical indicators, fundamental filters, and investor research. The timing and price-field details deserve care: the description says selection occurs before the open while referring to the day’s maximum decline, and the sample implementations may not consistently represent that timing or the stated conditions. Treat it as a basic screening idea rather than a validated strategy.

Key ideas

• The screen combines MACD above zero, positive price-to-earnings, and a daily decline between 4% and 5% from the prior close.
• It is intended to run before the market opens and ranks selected stocks by trading volume.
• The note provides indicator formulas and illustrative implementation snippets but no backtest evidence.
• The author flags data mismatch, price-based selection bias, and the elevated risk of stocks with large declines.
• The stated pre-open timing may not align with using the current day’s maximum decline.
