Screening Low-Priced Chinese Stocks After a Limit-Down Auction Signal

Summary

The post describes an equity screen combining three conditions: amplitude above a stated threshold, a prior-day 9:15 matched price identified as limit-down, and a price below a specified level. It proposes selecting up to a chosen number of qualifying stocks and, in the sample Python outline, sorting them by popularity. The accompanying indicator expressions are intended as references for implementing the conditions in a charting or stock-selection environment.

The post interprets the combination as seeking inexpensive, volatile shares affected by market sentiment, but supplies no backtest, return data, or evidence that the signal predicts performance. It cautions that low-priced stocks can carry business and financing risks and that the screen omits fundamentals and broader market behavior. It suggests adding valuation and technical measures, though it does not test those additions. The formula and code are platform-dependent examples that require validation before use.

Key ideas

• The proposed screen combines recent price amplitude, a prior-day opening-auction limit-down condition, and a low-price filter.
• The example suggests ranking qualifying stocks by popularity and taking a configurable number.
• The post provides indicator and Python references but no backtest or performance evidence.
• It warns that low-priced shares may have fundamental risks and recommends considering additional filters.
