A-Share Screening with Convertible-Bond Links and Auction Buy Pressure

Summary

This A-share stock-selection proposal combines price amplitude above 1, the presence of an outstanding convertible bond, auction-period price gains associated with large buy orders, and a combined large and extra-large buy volume threshold of more than 0.7 ten-thousands. It presents these conditions as indicators of volatility, a company financing feature, and buying interest. An indicator formula and a Python example are included, though the Python excerpt also applies filters and data fields that do not transparently correspond to the stated auction-based rule.

The post does not report backtest results or establish that the signals predict returns. It notes that trading-activity filters can attract speculative or poor-quality stocks and may not respond promptly to macroeconomic or policy changes. It suggests adding fundamental and macroeconomic measures, but these proposed enhancements are not evaluated in the document.

Key ideas

• The proposed screen combines price amplitude, an outstanding convertible bond, auction-period price movement, and large-order buying volume.
• The document treats auction buying as a proxy for market interest, without providing evidence that it predicts returns.
• The Python example includes additional filters whose connection to the stated auction rule is unclear.
• The post warns that transaction-based screening can select speculative stocks and omit fundamental or macroeconomic risks.
