Screening Chinese Main-Board Stocks with RSI, Daily Gain, and Range

Summary

The screening rule selects main-board stocks with a 14-period RSI below 65, a daily price increase greater than 1%, and an intraday high-low range exceeding 1% of the previous close. The examples also exclude suspended and special-treatment stocks, filter out certain financial sectors, and remove stocks that had reached the prior day’s upper price limit. One version sorts qualifying names by market capitalization. The intended rationale is to combine a not-too-high RSI with positive daily momentum and sufficient price movement.

The article characterizes the screen as short-term and warns that it can be overly dependent on price action and market sentiment. It notes risks from manipulation, abrupt price moves, and neglect of company fundamentals or longer-term prospects. It recommends risk controls and suggests adding other technical measures and fundamental data, though it does not specify a tested combined rule. The provided query and Python example show how to calculate and apply the filters, but there are no backtest results, trade outcomes, or evidence that the screen produces an edge.

Key ideas

• The screen requires RSI below 65, a daily gain above 1%, and an intraday range above 1% of the previous close.
• The examples filter out suspended and special-treatment stocks and exclude prior-day limit-up names.
• The rationale combines a moderate RSI reading with positive daily price movement and volatility.
• The source warns that short-term signals can be vulnerable to manipulation and can ignore fundamentals.
• No performance test is reported, and the suggested additions of other indicators or fundamental data are not quantified.
