A-Share Stock Selection Using Turnover, Bid Depth, and Three Limit-Up Days

Summary

This Chinese stock-selection note describes a screen combining three conditions: turnover between 3% and 12%, best bid volume greater than best ask volume, and a stock that had three consecutive limit-up sessions on the previous day. The proposed rationale is that the limit-up pattern may identify active themes or stocks, while the order-book comparison may favor names with stronger immediate buying interest and liquidity.

The post characterizes the approach as sentiment driven and cautions that it may expose traders to chasing sharp moves and subsequent reversals. It suggests adding company fundamentals, such as profitability measures, and technical indicators for broader screening. No backtest, return series, implementation details, or evidence supporting the proposed signals is provided; the article’s code references are absent. The screen should therefore be read as a hypothesis for further research rather than a validated trading strategy.

Key ideas

• The screen selects stocks with turnover between 3% and 12%, greater best-bid than best-ask volume, and a recent three-session limit-up sequence.
• The author treats repeated limit-ups as a possible indicator of market attention and hot stocks.
• Comparing top-of-book bid and ask volumes is intended to favor stocks with stronger visible buying interest.
• The post warns that a sentiment-based screen can encourage buying into sharp rises and expose traders to reversals.
• The article gives no backtest or performance evidence for the selection rules.
