Stock Screening by RSI, Positive PE, and Recent Limit-Up Frequency

Summary

This A-share screening proposal looks for stocks with RSI below 65, positive price-to-earnings values, and at least two limit-up sessions within the preceding 500 days. The article presents the limit-up condition as a way to identify actively traded or popular stocks, while RSI and PE supply technical and valuation filters. It includes brief indicator references and a Python example, but does not report a backtest or other evidence that the screen improves returns.

The article warns that stocks selected for past limit-ups may pull back after strong advances and that a small candidate pool can make results unstable. It suggests adding further fundamental and technical measures and adjusting the limit-up threshold to suit risk preferences. The code should be treated cautiously: its RSI test appears to compare a price-change field with the RSI threshold, and its PE calculation and data fields are not clearly consistent with the stated definitions. The sample therefore needs correction and validation before it can represent the proposed screen.

Key ideas

• The proposed screen requires RSI below 65, positive PE, and at least two limit-up sessions during the prior 500 days.
• The article gives no test results supporting the screen's effectiveness.
• Past limit-up activity may be followed by a reversal, and the candidate set may be unstable.
• The sample code's RSI and PE calculations do not clearly match the stated criteria.
