In this month's meeting we noticed that one of the stocks in
our portfolio was showing a "wrong" total return, all of the
other numbers however were correct, as far as I can tell.
Here are the numbers:

On 9/20/00 we bought 6 shares of XYZ for $15/share and a $12
commission (kinda stupid I know...). Then on 5/21/01 we
bought 26 shares of XYZ for $16.27/share and a $12
commission. So our average cost per share is 16.782 our
total cost is $537.02 and at a current price of $15.95 our
current value is $510.40.

As far as I can figure that is a loss of about 5% and the
CAR is about a loss of 30%. In bivio this is what is shown,
is the 30% loss. However, in NCA it is shown with a total
return of a loss of 23% and a CAR of about 30%. So for some
reason the total return in the NCA software is showing a
loss of 23% vs. the REAL loss of 5%.

Anyone have any ideas as to where this error could be coming
from, all of our other stocks seem to be correct. I have
been beating my head upon my keyboard trying to figure this
out. My next step is to delete that stock from NCA and the
re-enter all of its data and see if that solves it.

Thanks, for any help.

Actually, on an *annualized* basis you have a real loss (CAR) "of about 30%".   Beyond that, the "Total Return", as reported in NCA, seems to cause more confusion for most clubs than it's worth, see  http://www.better-investing.org/clubs/ladies.html .    Thus,  bivio has elected to leave the "Total Return" calculation off of the performance reports and only report the annualized internal rate of return (CAR).   If you are really glutton for more punishment you can delve into the following explanation of NCA's return calculations  at http://www.better-investing.org/clubs/calculations.html
 
In simple terms, let's look at this another way.  Let's say that you have $1000 invested in a stock that pays a 10% annual dividend.   The dividend is paid each quarter.   How much dividend do you expect to get each quarter?   The correct answer is $25 a quarter, $100 a year.   You could look at this dividend in the same way that you look at the performance reported by your accounting software.   After one quarter you've received $25 on a $1000 investment.  Yes, you've only received a 2.5% "real" return, however, on an annualized basis you've received a 10% return.   Unfortunately, as in your case,  the process of calculating rates of return gets even more complex when you have multiple cash flows into or out of an investment.  You'll find a more detailed explanation of these calculations at https://www.bivio.com/hp/investment-performance-report.html
