Designing and Assessing Twenty-Day Stock Money-Flow Factors
Summary
The document introduces a stock factor study based on cumulative net money flow over the previous 20 trading days, scaled by the stock’s market capitalization on the current day. It presents this normalization as a way to compare flows across stocks and proposes separate measures for combined large and extra-large order flow, extra-large orders, large orders, and medium orders. The stated motivation is to assess the effectiveness and robustness of individual factors before using them in multi-factor research.
The material gives a factor-construction outline, but the referenced body is only a PDF path; no test design, sample period, performance statistics, or robustness findings are included. There is also an apparent naming duplication for the extra-large and large order factors, so their identifiers cannot be confidently distinguished from the text. The document therefore describes a research starting point rather than demonstrating that money flow predicts returns or explaining how to build a portfolio from the signals.
Key ideas
- The proposed signal divides each stock’s cumulative net money flow over 20 trading days by its current market capitalization.
- Separate factors are intended to capture combined large-order flow and flows from different order-size categories.
- The stated research aim is to evaluate single-factor effectiveness and robustness before multi-factor analysis.
- The text supplies no empirical results, test period, or detailed portfolio construction procedure.
