A-Share Screening by Turnover and Convertible Bond Association

Summary

This post proposes screening Chinese A-shares by turnover rate, excluding Beijing-listed shares, and requiring a nonempty name for an outstanding convertible bond. It presents the rule as a technical screening approach and suggests examining convertible-bond issuance and performance, then adding valuation measures and other business or industry indicators to broaden the selection criteria.

The post includes formula and Python examples, but their implementations do not cleanly match the stated rule: the Python sample appears to identify stocks by whether their codes occur in a convertible-bond list, and its exchange and code-prefix filters do not clearly implement the Beijing exclusion. It also provides no historical test, benchmark, or evidence that the screen selects stable or growth-oriented stocks. The author acknowledges that relying mainly on technical conditions can omit fundamentals and may produce too many or too few candidates, so the screen should be treated as an unvalidated starting point rather than a demonstrated strategy.

Key ideas

• The proposed screen selects shares within a stated turnover band and excludes Beijing-listed stocks.
• It also requires an association with an outstanding convertible bond whose name is available.
• The author suggests adding valuation, fundamental, industry, and bond-performance information.
• The post supplies no backtest or performance evidence for the screen.
• The example code's filters do not clearly implement all of the written conditions.
