Chinese Stock Screen Using Price Range, Convertible Bonds, and Volume
Summary
This Chinese A-share screening rule combines daily price movement, convertible-bond information, and trading activity. It looks for stocks with at least a 1% absolute daily price change, a nonempty outstanding convertible-bond name, and volume at or above its 5-, 10-, 20-, and 30-day averages. Candidates are ranked by transaction amount, used here as a proxy for capital strength. The accompanying explanation presents volatility as a risk clue, bond data as additional context, and stronger activity as a possible sign of liquidity or investor interest.
The article includes indicator-formula and Python examples, but their implementations do not align perfectly with the prose: the formula excludes a named market segment and checks volume averages, while the Python sample filters exchange listings and sorts by amount. No historical test results or performance evidence are provided. The article also warns that ranking by activity can lag and that rapid market moves call for risk controls. It suggests adding technical or fundamental measures, but gives no validated weighting scheme or evidence that the proposed screen is profitable.
Key ideas
- The screen requires an absolute daily price move of at least 1% and available convertible-bond name data.
- It uses volume above several moving averages as a measure of elevated trading activity.
- Candidates are ordered by transaction amount as a proxy for capital strength.
- The article cautions that activity-based ranking may lag and provides no backtest evidence.
