A-Share Screen Using Intraday Buying and Price Conditions

Summary

The document describes a short-term stock selection rule for Chinese main-board shares. It combines a threshold for the day’s reported increase in holdings with a positive daily move and a limit on the percentage gain at 9:25. The accompanying discussion interprets these as signs of buying interest, relative strength, and room for further appreciation, then suggests adding valuation and technical measures or using a longer analysis horizon.

It provides no backtest, performance figures, or evidence that the screen predicts returns. Its code example uses different comparisons and price fields from the stated rule, so the implementation does not clearly reproduce the described conditions. The measure of “increase in holdings” and its data source are also not defined. The rule is therefore best read as an illustrative screening idea; it may miss fundamental and longer-term risks and can fare poorly when the broad market weakens.

Key ideas

• The proposed screen combines reported buying activity, a positive daily move, and a cap on the early-session gain.
• The accompanying rationale treats these conditions as signs of buying interest and potential upside.
• The document suggests adding valuation and technical indicators or extending the analysis period.
• It supplies no performance evidence, and its code example appears inconsistent with the written screening rule.
