Screening Main-Board Stocks for Consecutive Gains and Daily Strength

Summary

This post proposes screening main-board stocks using a combination of price range, a streak of consecutive limit-up sessions on the prior day, and a current-day gain above a stated threshold. It presents the conditions as a way to focus on volatile stocks with recent market strength. The article also includes formula and Python examples, although the code references futures-market data and contract fields, which do not clearly implement the stated main-board stock screen.

The author identifies two main limitations: a short-term performance filter may ignore financial health and longer-term behavior, and restrictive conditions can leave too few candidates for diversification. Suggested refinements include adding financial and sector information and loosening the screen. The post does not report a backtest, returns, or evidence that the selection logic predicts future performance. Its screening idea therefore needs clearer definitions, data-field alignment, and testing before it can support investment decisions.

Key ideas

• The proposed screen combines a price-range condition, a recent consecutive limit-up streak, a current-day gain threshold, and main-board membership.
• The post interprets volatility and recent price strength as signs of market interest.
• It warns that short-term filters can overlook financial fundamentals and longer-term behavior.
• Strict conditions may produce too few stocks to support a diversified portfolio.
• The included code examples do not clearly match the stated stock-screening criteria, and no backtest evidence is provided.
