Chinese Robot-Theme Stock Screen Using Auction Price and Valuation Filters

Summary

This Chinese equity screen combines a daily amplitude threshold with a prior-day 9:15 matching-price limit-down condition, robot-industry membership, and a circulating market value below 10 billion yuan. The final version adds a price-to-earnings ratio below 30, then ranks qualifying stocks by popularity and selects up to five. The document gives example indicator expressions and a Python-style illustration, but the supplied code references platform-specific fields and functions that are not defined as standard library calls.

The article suggests adding fundamental and technical factors, stop-loss controls, and historical testing. It also cautions that the screen omits sector trends and may overfit or fail in other market conditions. No backtest results or evidence of profitability are provided, and the proposed filters alone do not establish that a stock is attractive or that the auction condition predicts subsequent returns.

Key ideas

• The screen selects robot-concept stocks using amplitude, a prior-day opening auction price condition, circulating market value, and valuation.
• The final selection adds a price-to-earnings ceiling of 30 and ranks candidates by popularity.
• The article recommends broader factor analysis, risk controls, and historical testing as possible improvements.
• It warns that sector movements and changing market conditions may undermine the screen.
