- Order: Activity score out of 100: recency of the latest fund filing or dated deal (35: full marks within 3 months, then stepping down at 6, 12 and 24 months), share of the observed portfolio in this sector (25; half of that when the sector is stated only), stated focus on the US (15: full marks when the firm names the US as where it invests, half when it says global), size of the fund on file on a log scale (15) and completeness of the public record (10). Regional focus is our research, not an SEC figure. It is a measure of activity and fit, not of quality or returns.
