Concept Momentum and Limit-Up Continuation for Chinese Intraday Stocks

Summary

This A-share strategy narrows a stock universe in three stages: rank industry or concept indices by short- and medium-term momentum, select stocks with a current limit-up and a recent prior limit-up, then confirm strength after the open before buying. Candidate filters also exclude certain listings and special-treatment stocks, require a minimum trading value and market capitalization, and match each stock to a leading concept. The described portfolio uses equal weights, limits the number of new positions, and exits positions after a minimum holding period when a profit threshold is reached.

The document reports a backtest return and drawdown over a specified period, but supplies no supporting performance series or detailed risk and bias analysis; the risk and improvement sections are largely headings. It says live use would require automation. Results may depend on historical data, execution at limit prices, market impact, and the handling of intraday signals. The stated rules therefore describe a testable momentum and breakout approach, not evidence of robust live performance.

Key ideas

• The strategy first selects concepts with strong short- and medium-term momentum rankings.
• Stock candidates must show a current limit-up and a recent limit-up while meeting liquidity and size filters.
• An intraday price-strength condition triggers equal-weight entries, subject to a cap on new positions.
• The exit rule takes profits after a minimum holding period when a position reaches the stated gain threshold.
• The reported backtest lacks detailed supporting analysis of execution assumptions and bias risks.
