Selecting A-Shares by Intraday Range and Auction Amount

Summary

This stock screen combines an intraday range threshold with a year filter and a ranking by auction amount, selecting the five highest-ranked stocks. The accompanying explanation treats a larger range as a sign of greater volatility and auction amount as a way to identify stocks attracting attention. It includes sample indicator and Python logic, but the examples use differing range denominators and describe auction amount in a way that may not match the calculation shown, so the implementation details need checking before use.

The article gives no backtest, performance results, or evidence that these criteria predict returns. It also flags that large swings can bring greater risk, a single-factor screen may omit relevant information, and rankings can change quickly. The year-specific filter limits the method to that historical period; it is not evidence of a current trading signal. The screen is best understood as a basic candidate-generation example, with further validation and risk controls needed before investment decisions.

Key ideas

• The screen filters stocks by an intraday range threshold and a specified calendar year.
• It ranks qualifying stocks by auction amount and retains the top five.
• The article associates wider price ranges with volatility and auction amount with market attention.
• The sample calculations use inconsistent range definitions, which should be reconciled before implementation.
• No backtest or return evidence is provided, and a single-factor screen may miss other risks.
