2022-07-28: Important Note - We have changed the treatment of the Δ Portfolio % column in this table. Previously, we were reporting it as the percent change in the portfolio allocation. We are now reporting it as the raw change in the portfolio allocation (still reported as a percent). In formula terms, we were previously reporting it as 100 * (current allocation - prior allocation ) / prior allocation. We are now reporting it as (current allocation - prior allocation).
