Hot-Stock Screening with RSI and Prior Limit-Up Signals

Summary

The article proposes a Chinese equity screening rule that ranks stocks by trading heat, then filters for an RSI below 65 and at least one limit-up session during 2021. Its code example retrieves daily data, computes a 14-period RSI, checks for a qualifying historical percentage gain, and includes an additional condition comparing the latest open with a 10-session moving average. The example first considers a subset of stocks ranked by current trading amount.

The article suggests that combining technical conditions with market attention may identify candidates, but it provides no backtest, return series, benchmark, or evidence that the screen selects undervalued stocks. It also acknowledges the risk of overemphasizing popular stocks and short-term limit-up events, which may miss more persistent opportunities and may be unsuitable for long holding periods. It recommends adding broader market, industry, and fundamental factors, though it does not specify or test those additions.

Key ideas

• The proposed screen combines a 14-period RSI below 65 with a limit-up event during 2021.
• Stocks are ranked by trading heat, with the example using current trading amount to form an initial candidate list.
• The code example also requires the latest open to exceed its 10-session moving average.
• The article warns that attention to popular stocks and past limit-up moves can bias selection toward short-term behavior.
• No backtest or performance evidence is provided for the screening rule.
