Screening Intraday Stock Rallies for Shorting Candidates

Summary

The document describes a stock-screening process that looks for shares rising beyond a chosen percentage threshold during intraday trading, with the aim of identifying candidates for short positions. A first stage compares the current price with the prior close across a stock list. A second stage reviews historical threshold-crossing events and computes measures such as event frequency, average rise, subsequent declines, next-three-day price movement, RSI, recent negative days, annual high and low, and correlation with an index. The author suggests using these measures to select a candidate and closing at the end of the day or at a profit target.

An example reports that a threshold screen reduced a list of 146 stocks to six, and describes one stock as a possible candidate based on its historical metrics. These are screening illustrations, not evidence of a verified trading edge. The document gives no robust out-of-sample evaluation or accounting for execution costs, borrow availability, short-sale constraints, or risk controls. Its historical patterns and example candidate therefore require independent testing before use; threshold crossings and average declines do not guarantee a profitable short trade.

Key ideas

• The screening process first identifies stocks whose intraday gains exceed a selected threshold.
• Historical threshold-crossing events are summarized with frequency, average rise, subsequent price change, RSI, and index correlation.
• The metrics are intended to rank potential short candidates rather than automatically establish a trade.
• The author proposes exiting at the close or using a profit target, with stop losses as a possible addition.
• Historical event averages alone do not demonstrate profitability, particularly without costs and execution constraints.
