## Research question

What does the source-diverse evidence say about percentage return or alpha premium diverges across return predictive signal portfolio in firms portfolios funds?


**Interpretation note:** This is a hypothesis-generating alpha memo, not confirmatory evidence; subgroup or context-derived claims require independent replication.

## Why this is surprising

The bounded signal is disagreement, not a settled effect: the receipts share a comparable intervention/outcome frame but split between near-zero estimates and material percentage return or alpha premium estimates.
Treat the spread as method-sensitive heterogeneity: the shared shape is the replication screen, while the estimates vary with hurdle rates, samples, and replication definitions.
Near-zero receipts: An increase of one standard deviation in EPU is associated with a 1.5% increase in forecasted three-month abnormal returns.
Material-effect receipts: an excess return of 13.13%; Portfolio returns are 26% lower out‐of‐sample; earn abnormal returns of roughly 11 percent per year.

## Evidence shape

- **population:** firms portfolios funds
- **intervention:** return predictive signal portfolio
- **signal_family:** return predictive signal
- **comparator:** benchmark or opposite signal portfolio
- **outcome:** risk adjusted portfolio returns
- **metric:** percentage return or alpha premium
- **study_design:** empirical asset pricing

## Evidence receipts

- `fact_id=portfolio returns/auto/2022/alpha excess portfolio return 344924` (`A_core`) - an excess return of 13.13%
- `fact_id=portfolio returns/auto/2015/excess market returns 333830` (`A_core`) - An increase of one standard deviation in EPU is associated with a 1.5% increase in forecasted three-month abnormal returns
- `fact_id=portfolio returns/auto/2015/portfolio returns 333817` (`A_core`) - Portfolio returns are 26% lower out‐of‐sample
- `fact_id=asset pricing/auto/2014/portfolio returns alpha 333823` (`A_core`) - firms in mobile industries earn returns over 5% higher than those in less mobile industries
- `fact_id=portfolio returns/auto/2013/abnormal returns 333815` (`A_core`) - earn abnormal returns of roughly 11 percent per year

## What would weaken this

- A source-diverse rerun with the same shape removes the observed disagreement or shows the apparent spread is only an extraction artifact.
