A Volatile-Stock Pullback Screen After a Recent Limit-Up

Summary

This screen looks for stocks with an intraday range above 1%, at least one limit-up event in the prior 25 days, and a current decline from the session high of 4% to 5%. The article frames the range as a volatility signal, the recent limit-up as evidence of prior strong demand, and the pullback as a possible rebound setup. It provides formula and Python examples intended to identify qualifying stocks.

The article offers no backtest or evidence that these conditions lead to rebounds. It cautions that historical price patterns may not persist and that the screen omits company finances and seasonal influences. It suggests adding valuation, profitability, industry, and market factors. The examples contain apparent logic inconsistencies: the Python conditions combine a limit-up test with same-day range and pullback checks, rather than clearly testing for a limit-up within the previous 25 days. The stated pullback measure also needs careful definition before implementation.

Key ideas

• The stated screen combines an intraday range above 1%, a limit-up event in the previous 25 days, and a 4%–5% decline from the day's high.
• The article presents the setup as a possible pullback-and-rebound candidate, not a proven signal.
• It warns that historical patterns may not continue and that the screen omits financial and seasonal factors.
• The code examples should be validated because their limit-up logic may not implement the stated lookback condition.
