Selecting High-Amplitude Chinese A-Shares by Auction Turnover

Summary

This proposed stock screen selects non-Beijing A-shares with amplitude above one and ranks candidates by the day’s opening-auction amount, keeping the top five. Its rationale is that large amplitude may identify stocks with greater price movement, while high auction turnover may filter out names with little trading activity. The post presents the screen as a way to combine a price-movement condition with an activity ranking.

The article offers no backtest, performance figures, or evidence that either selection condition predicts returns. It also notes that the rules omit company and industry fundamentals and that excluding Beijing-listed companies could remove attractive candidates. The sample code and indicator references are described as examples requiring modification; the post does not establish that the code accurately implements the stated auction-ranking condition. It suggests adding valuation and industry measures, but gives no tested optimization.

Key ideas

• The screen requires stock amplitude above one and ranks stocks by opening-auction amount.
• It retains the top five candidates while excluding Beijing A-shares.
• The proposed rationale links amplitude to price movement and auction activity to liquidity.
• The post supplies no backtest or evidence of predictive returns.
• Fundamental and industry factors are omitted, and the implementation examples may need adjustment.
