I have a question regarding IRR.
I am trying to figure out the IRR for an investment (actually, this has come
up a number of times in the past). Unfortunately, it is not one of those
simple cases where the initial investment is negative and all subsequent cash
flows are positive. There are a couple of times when the cash flow signs
switch. I understand the multiple IRR issue, but it still doesn't help that I
cannot get a return number from Excel.
I have to imagine that these cases, where the negatives and positives switch
more than once, is common. It is difficult to just say "well, there is no
IRR". I still need to know what the rate of return would be. What can I do?
Please help.

Thanks.
