Dear Statalisters:
I am struggling with calculating internal rate of return (IRR) of series
bonds. I would really appreciate if someone can help me out.
The dataset is as following:
Series��� Issue_date�������� maturity�������������� par_amount ����� coupon
��������������� Issue_price
1���������06/15/00�����������06/15/05������������� 7275������
�����5������������� �������100.75
2���������06/15/00�����������06/15/06������������� 7265������
�����5������������� �������100.05
��.
14��������06/15/00�����������06/15/15������������� 6480������
�����4.5��������� ����������96
Observations in the dataset are different series of one bond issue, so they
all have the same issue date but different maturity dates. ��I need to
calculate the internal rate of return of the whole issue by pooling the cash
flows of different series together. In other words, I need to generate only
one IRR based on the cash flow of all these series.
I was not able to find a stata function for IRR calculation, although I did
find an ado file (finirr). The ado file seems to calculate it with a ml
command and requires a data structure as follows:
Time����� Cash_flow
Year_1� 100
Year_2 -105
Any input on how to transform my dataset to fit the finirr format would also
be appreciated.
Thank you.
Best
Gao
