Opening-Gain, Turnover, and Capitalization Filters for Stock Selection

Summary

This stock-selection recipe begins with shares whose 9:25 a.m. price gain is below 6%, circulating market capitalization is above 10 billion yuan, and volume ratio ranks among the top 100. The explanation frames the volume measure as a way to find actively watched stocks, the capitalization threshold as a scale filter, and a limited opening gain as a possible low-entry opportunity. The final proposed logic adds turnover above 5% and a price-to-earnings ratio below 20.

The document provides indicator names and a code stub, but no complete implementation, backtest, or performance evidence. It cautions that volume and capitalization measures may be manipulated or fail to represent genuine liquidity, while opening moves can be unstable because of market sentiment. Its suggested refinements include adding indicators and technical analysis. The low-entry interpretation is asserted rather than demonstrated, and the source does not establish that the combined thresholds improve returns or control risk.

Key ideas

• The initial screen uses a top-100 volume-ratio rank, a capitalization floor, and a cap on the 9:25 a.m. gain.
• The final proposed criteria also require turnover above 5% and a price-to-earnings ratio below 20.
• The source presents active trading, larger scale, and a potential low-entry opportunity as rationales for its filters.
• It provides no backtest, measured results, or complete working strategy implementation.
• It warns that the input measures and opening prices can be unreliable or unstable.
