Stock Screening by Turnover, Bid Depth, and Recent Price Spikes

Summary

This A-share stock selection idea filters for turnover between 3% and 12%, first-level bid volume greater than first-level ask volume, and at least one daily gain of 10% or more during the prior 25 trading days. The article frames the turnover band as a liquidity screen and the bid-versus-ask comparison as a sign of buying interest; the recent large gain selects stocks that have shown strong price movement.

The document provides no backtest, performance evidence, or implementation details beyond stating the selection criteria. It acknowledges that the screen relies heavily on technical conditions, may amount to chasing recent winners, and omits fundamentals and other drivers. It suggests adding technical indicators or fundamental measures, but does not evaluate whether those changes improve results. Signal definitions, execution assumptions, transaction costs, and risk controls are not specified, so the idea should be treated as a preliminary screen rather than a validated strategy.

Key ideas

• The screen selects stocks with turnover from 3% through 12%.
• It requires first-level bid volume to exceed first-level ask volume.
• A stock must have recorded at least one daily gain of 10% or more within the preceding 25 trading days.
• The article warns that the screen may chase short-term strength and ignores fundamental factors.
• No backtest or evidence of profitability is provided.
