I am enrolled in CIPM Level 1 and not as a Level 1 CFA candidate. I have been unable to come up with the right answer or enter it correctly in my BA II Plus calculator.
From the textbook, calculate the internal rate of return of a portfolio with following valuation points and external cash flow (where dollar amounts are in millions):
Market Value 31 March $56.3
Market Value (prior to cash flow) 11 April $58.2
Contribution (made at end of the day 11 April $9.8
Market Value 30 April $69.6
Solution: 69.6 = 56.3 x (1 + R) + 9.8 x (1 + R) 19/30 = 5.61% ((1 + R) is raised to 19/30 - I am not sure how to show it as an exponent)
Note: The mid-period valuation on April 11 is not necessary for completing the IRR calculation.
