Chinese Stock Screening with Intraday Inflows and Convertible Debt Data

Summary

This Chinese stock selection proposal screens for shares with daily amplitude above a stated threshold, afternoon large-order net inflow, and a nonempty name for outstanding convertible bonds. It treats price fluctuation and order-flow data as signals of trading activity, while the convertible-bond field is presented as information about a company’s debt situation. The post provides indicator expressions and a Tushare-oriented code example, but it does not report a backtest, portfolio returns, or evidence that the combination predicts future performance.

The author cautions that relying heavily on the convertible-bond field and a small set of indicators cannot capture a company’s full fundamentals or policy exposure. Suggested improvements include considering profitability, growth, valuation, industry context, and block trades, followed by broader fundamental and technical review, risk controls, and capital management. The rule is therefore a preliminary screen rather than a validated investment strategy; the document also does not define a complete portfolio construction or execution process.

Key ideas

• The screen combines price amplitude, afternoon large-order net inflows, and an outstanding convertible-bond data field.
• The proposed signals reflect trading activity and a limited aspect of corporate debt information.
• The document supplies indicator and data-fetching examples but no backtest or performance evidence.
• The author recommends adding company fundamentals, industry analysis, and risk and capital controls.
• The selected shares require further assessment before their investment value and risks can be judged.
