  • August Rebalance Report

    As always, we present the following data without commentary. Cut-off date used was 7/28 this month. The rebalance was completed as of 01:00 UTC on 8/1. Month to date data is from 7/1 to 8/1. Quarter to date data is from 4/1 to 8/1 as Q3 to date would be identical with month to date. If there are any missing performance metrics you would like to see, please let us know.

    BTC dominance reflects the bitcoin weight in our currency index. Market cap reflects only the Bletchley Total Index (70 assets). Turnover is defined as the total percent of assets that would need to be traded to properly track each index before and after the rebalance. Detailed asset weights and turnover statistics available here. Detailed float changes available here. Contribution is the portion of the return for the Bletchley 10 Index attributable to each coin.
