Chinese Stock Screen Using Price Range, Auction Volume, and Convertible Bonds

Summary

This article presents a technical stock screen for Chinese equities. Its stated conditions are an amplitude above 1, a measure formed from the previous day's turnover and the ratio of current auction volume to previous volume within a specified band, and a non-empty name for an outstanding convertible bond. The rationale is that the combination may identify active stocks during periods of market interest, when increased volume could accompany price movement.

The author notes that the screen omits company fundamentals and capital-flow considerations, may miss relevant stocks, and uses a restrictive convertible-bond condition. Sector classification, parameter adjustment, and convertible-bond measures are suggested as possible refinements. The article includes formula and Python references, but their calculations and definitions do not fully match the prose, including how amplitude and volume ratios are computed. It offers no backtest or performance evidence, so the screen should be read as a proposed selection heuristic rather than an established strategy.

Key ideas

• The screen combines a price-amplitude condition with a turnover and auction-volume measure.
• It additionally requires an outstanding convertible-bond name to be present.
• The proposed rationale is to find active stocks that may attract interest during hot markets.
• The author acknowledges that technical-only filters can omit fundamental and capital-flow information.
• The implementation examples differ in some details from the prose, and no performance evidence is given.
