Stock Screening by Recent Gains, Auction Limit-Down, and Buying Activity

Summary

This Chinese equity screen combines three conditions: a positive but below 35% return over ten days, a prior-day 9:15 indicative auction price at the limit-down level, and a current increase in holdings share above 5%. The article interprets the holdings increase as a sign of investor attention, the auction price as evidence of selling pressure, and the bounded recent gain as a way to avoid shares that have risen too far. It proposes selecting stocks that meet all three filters.

The post warns that attention and price movement alone may not forecast future performance, may favor volatile high-risk shares, and may exclude quieter stocks. It recommends adding conditions and using broader data sources. The sample code is presented as illustrative, but it does not demonstrate reliable calculation of each stated measure or establish that the auction and holdings fields map to those concepts. No backtest or performance evidence is provided.

Key ideas

• The screen combines a positive return below 35% over ten days with a prior-day auction limit-down condition.
• It also requires the current holdings-share increase to exceed 5%.
• The post links these filters to investor attention and price pressure but gives no performance results.
• It warns that the conditions may favor volatile stocks and omit lower-volatility candidates.
• The example code does not validate the measures or show that the screen predicts returns.
