Stock Screening with RSI, Listing Age, and the 9:25 Price Change

Summary

This Chinese stock selection method screens for shares with a 14-period RSI below 65, more than one year since listing, and a 9:25 price increase below 6%. The note frames RSI as a way to identify relatively weak recent performance, while the listing-age and opening-price filters are intended to exclude newer listings and large early moves. It provides example indicator logic and a Python outline using stock data and RSI calculations.

The author cautions that the screen omits company financial health and other important factors, and does not account for transaction costs or slippage. Suggested additions include valuation and profitability measures and historical volatility, but these are proposals rather than tested refinements. No backtest or return data is given, and the explanation’s characterization of RSI below 65 as identifying oversold shares is not established by evidence in the document.

Key ideas

• The screen combines RSI below 65, listing age above one year, and a 9:25 price increase below 6%.
• Its example uses a 14-period RSI and checks the early price change against the prior close.
• The note flags missing fundamental information, transaction costs, and slippage as limitations.
• It proposes adding financial measures and historical volatility, without reporting validation or performance.
