Screening Main Board Stocks by Turnover, Float Value, and Large-Order Flow

Summary

This proposed stock screen selects main board shares with turnover between 3% and 12% and circulating market value between 5 billion and 10 billion yuan. It also requires large-order net volume to exceed 0.05 for at least three consecutive days. The article presents this as a way to combine liquidity, company size, and a short-term measure of buying pressure, and includes example expressions for implementing the filters in screening software and Python.

The post offers no backtest, return figures, benchmark, or evidence that the screen identifies superior stocks. Its own caveats are that the rules use few inputs, may miss company or industry factors, and that large-order flow can fluctuate with market sentiment. The sample formulas also use absolute values of net order flow, which would not distinguish positive from negative readings as clearly as the prose description implies. The article suggests adding other indicators and considering holding period and risk tolerance, but does not define a complete entry, exit, or portfolio management process.

Key ideas

• The screen combines turnover, circulating market value, and large-order net volume filters for main board shares.
• It requires large-order net volume above the stated threshold on three consecutive days.
• The article provides example implementations but no backtest or performance evidence.
• The described filters may omit company, industry, and broader market information.
• Using absolute net-flow values can include negative readings despite the strategy's buying-pressure rationale.
