RSI, Daily Gains, and Turnover Filters for Main Board Stocks

Summary

This Chinese stock screen combines a 14-period RSI below 65 with a daily gain above 1%, main-board listing status, and a prior-day actual turnover rate between 3% and 28%. The article describes turnover as a proxy for investor attention and trading activity, while the RSI and daily return represent technical conditions. Its query example also requires price above the 250-day moving average and sorts candidates by trading volume. The Python illustration applies exchange and price filters, retrieves historical turnover, computes RSI, and returns a volume-ranked shortlist.

The examples are not fully consistent: the prose emphasizes prior-day turnover, while the code and query add or handle conditions differently, including the 250-day moving-average filter. No backtest or performance evidence is provided, and the article acknowledges that turnover can be distorted by speculative activity and that recent price behavior omits company fundamentals. It recommends combining technical and fundamental measures, accounting for share structure, and diversifying, but does not provide a tested implementation of those improvements.

Key ideas

• The core screen combines RSI below 65, a daily gain above 1%, main-board status, and prior-day turnover between 3% and 28%.
• The query example adds a requirement that price exceed the 250-day moving average and ranks by volume.
• The article presents turnover as a measure of market activity but notes that speculation can make it unusually volatile.
• The examples differ in their treatment of conditions, and the document provides no backtest evidence.
• It suggests incorporating fundamentals and diversification, without specifying or validating a combined method.
