Perfоrmаnce Repоrting: Mоdified Dietz Return Summit Cаpitаl Management is preparing a monthly performance report for a private wealth client. During January, the client made two contributions to the portfolio. Because daily valuations are unavailable, the performance team uses the Modified Dietz method, which weights each external cash flow according to the fraction of the reporting period it remains invested. Date Activity Portfolio Value / Cash Flow January 1 Beginning Market Value $[bmv] January 10 Portfolio Valuation $[val1] January 12 Client Contribution +$[cf1] January 18 Portfolio Valuation $[val2] January 23 Client Contribution +$[cf2] January 27 Portfolio Valuation $[val3] January 31 Ending Market Value $[emv] Question: Using the Modified Dietz method, what was the portfolio return for January? Assume January has 30 days. Use the actual timing of each contribution when computing the weighted average capital base. Type your answer as a percentage and not as a decimal. For example, enter 5.25 and not 0.0525. Round to the nearest two decimals, if needed. ```

Perfоrmаnce Repоrting: Mоney-Weighted Rаte of Return A weаlth management client started the quarter with an investment account and made an additional contribution halfway through the quarter. Hint: Initial Value and Contribution are both investments (Negative CFs). The advisor wants to calculate the client's money-weighted rate of return, using the internal-rate-of-return logic for the two sub-periods. Input Value Beginning Market Value $[bmw] Contribution at Midpoint of Quarter $[cf] Ending Market Value $[emv] Question: What is the money-weighted rate of return per sub-period? Type your answer as a percentage and not as a decimal. For example, enter 4.25 and not 0.0425. Round to the nearest two decimals, if needed.
