Screening Chinese Stocks by Daily Range and Convertible-Bond Data

Summary

This post proposes screening Chinese stocks for a daily price move of at least one percent, a nonempty name for an outstanding convertible bond, and exclusion from a specified market segment. It presents the range condition as a way to identify active stocks and the bond field as an additional data filter. The accompanying examples refer to an intraday range threshold and exclude stocks associated with a named segment, though the prose and code are not fully consistent about the market classification and range calculation.

The article provides sample indicator logic and Python code, but no backtest, candidate list, or performance evidence. It notes that omitting profitability and valuation measures can leave the screen broad and imprecise, and suggests adding technical or fundamental filters and accounting for industry differences. The code and data fields should be checked carefully: the example's price calculation may not implement the stated amplitude definition, and the segment exclusion differs across parts of the post.

Key ideas

• The proposed screen combines a daily price-move threshold, convertible-bond information, and a market-segment exclusion.
• The article treats the price-move condition as a proxy for stock activity, but does not show that it forecasts returns.
• No backtest results or evidence of screening performance are supplied.
• The prose and code differ in their market-segment and price-range details, so the implementation needs review.
• The post suggests adding fundamental, technical, and industry-specific filters to improve selection.
