An abbreviated, illustrative excerpt of the quarterly Professional-tier deliverable. Holdings and values are hypothetical. This demo sample runs 4 pages; the production report runs 14–20 pages and includes the complete methodology appendix.
Loadings estimated by cross-sectional regression of holdings' standardized factor scores, weighted by portfolio position size, against the coverage universe as of the report date. Scores are z-standardized within universe and winsorized at the 1st / 99th percentile. Zero denotes the universe average.
The portfolio's momentum loading of +0.34 places it in the 7th decile of the universe. The low-volatility loading of −0.21 indicates holdings with above-average trailing realized volatility relative to the universe. Size and reversal loadings are within one quarter of a standard deviation of the universe mean.
| Component | Share of portfolio variance | Annualized contribution |
|---|---|---|
| Market | 71.2% | 13.9% |
| Style factors (momentum, low vol, size, reversal) | 9.8% | 1.9% |
| Sector | 6.4% | 1.3% |
| Idiosyncratic | 12.6% | 2.5% |
Systematic sources account for 87.4% of variance over the trailing 36 months. Idiosyncratic variance of 12.6% is consistent with a portfolio of 42 positions with a top-ten concentration of 38.1%.
Average pairwise correlation across holdings rose from 0.36 to 0.41 over the quarter, in line with the broad-universe increase from 0.33 to 0.39 over the same period.
Factor definitions, estimation windows, and validation results are documented in Appendix A. All computations use data available as of each observation date.
