Momentum Screen Using Limit-Up Frequency, Institutional Trades, and Volume Ratio

Summary

This Chinese equity selection approach combines three signals: at least two limit-up sessions within ten days, institutional-only seats appearing in exchange trading disclosures, and a high volume ratio, with the latter ranked among the top 100 stocks. The note interprets repeated limit-ups as evidence of activity and attention, institutional seat data as a possible sign of buying, and elevated relative volume as a sign of strong capital flows. It suggests adding turnover and trading value, further institutional holdings data, and technical indicators such as MACD or KDJ.

The document provides a rationale and discusses potential pitfalls, but it reports no backtest, returns, or comparison group. High flows and institutional purchases can reverse, and repeated limit-ups may reflect unstable sentiment rather than sustainable strength. The description of the final selection rule is cut off, so it does not fully specify how the proposed refinements should be applied or combined.

Key ideas

• The screen looks for at least two limit-up sessions over a ten-day period.
• It uses institutional-only trading seats in disclosure data as a possible buying signal.
• It ranks stocks by volume ratio and selects the top 100 for that measure.
• The note warns that flow data, institutional activity, and market attention can reverse or mislead.
• No performance evidence is supplied, and the final refined rule is incomplete.
