A Five-Minute Stock Price-Impact Deviation Screen

Summary

This brief strategy note proposes ranking or selecting stocks by the deviation in price impact associated with five-minute capital flows. Its stated hypothesis is that stocks with smaller price-impact deviations perform better later; it describes these as stocks that were relatively easy to push down and difficult to push up in the preceding period. The suggested action is to buy qualifying stocks.

The note does not define the deviation calculation, specify the sampling and holding periods, or provide code, backtest results, or supporting data. It points readers to an external strategy implementation, so the screening concept is only sketched here and cannot be independently reproduced from the document. The claim should therefore be treated as a hypothesis, with execution costs, liquidity, and robustness left unaddressed.

Key ideas

• The proposed signal uses five-minute capital-flow data to estimate price-impact deviation.
• The strategy hypothesizes that stocks with smaller deviations may perform better subsequently.
• The note suggests buying stocks that meet the signal condition.
• It provides no calculation details or performance evidence in the document.
