Chinese Stock Screening with a Rising 30-Day Average and Auction Filters

Summary

The document presents a Chinese stock screen using three initial signals: a rising 30-day moving average, an opening auction change between -2% and 5%, and a reported increase in position share above 5%. The article interprets the last condition as evidence of greater trading activity and net inflows, and the moving average as a trend filter. Its final proposed screen adds price-to-earnings below 20, price-to-book below 1, and a MACD bullish crossover.

The piece explains the rationale for these filters and suggests combining technical signals with valuation measures. It gives only a sketchy code reference, with incomplete or unclear data fields and calculations, and no backtest or return evidence. The article also cautions that flows do not ensure continued price gains, high expectations may coincide with volatility, and technical signals can be distorted by news or sentiment. The rules therefore describe a candidate selection heuristic rather than a demonstrated investment strategy.

Key ideas

• The initial screen combines a rising 30-day moving average, a bounded auction move, and an increase in position share above 5%.
• The final proposed rules also require price-to-earnings below 20, price-to-book below 1, and a bullish MACD crossover.
• The article interprets the flow condition as a sign of stronger activity, but says inflows do not guarantee further gains.
• No backtest is provided, and the code example is incomplete and difficult to validate.
