problem when creating a series of matrix
 

I would like to create a number of matrixes from a list (covariance
between assets over time).
I put =MMULT(TRANSPOSE(O2:S25);O2:S25)/24 in excel and get a 5x5
covariance matrix calculated
on the dates 9301-9412 (January 93 until December 94 - 24
observations). I would like new matrix for every new months (moving
one month at a time). The next would refer to 9302-9501 or =MMULT
(TRANSPOSE(O3:S26);O3:S26)/24 and so on. The problem now is that I
cannot simply copy the matrix below the previous one because that one
is five rows down and refer to the date 9306-9505.

I would be very thankful if some one knows how to do, maybe with a
macro or in some other way.

Don't use a calendar month, instead use a 30 day month.

Thanks for your replay! I do not have the daily data though...

At the top of the pmatrix for each month if you included the month number
then you can use the Address function to create a reference offset from O2.

ok, seems great but i'm not sure i'm following. Could you explain that a
little more. Thanks!

Then formula for 1st month is

=MMULT(OFFSET(O2,B20-1,0,24,5);OFFSET(O2,B20-1,0,24,5))/24

Then formula for 2nd month is (30 rows down the spreadsheet)

Sorry, I do not understand that. whta does the colunn 1, 2, 3... and the
colunn123, 124, 125... refer to? If the stock returns are below, does that
work then? In my first message I had counted the excess returns and the
MMULT(...) funktion was on the excess return but if you use the offset
funktion you can count on the returns directly right?

what you included below is the sheet where the formulas will go. I would
need to see the sheet where the data is located to write the formula.

Then formula for 1st month is

=MMULT(OFFSET(O2,B20-1,0,24,5);OFFSET(O2,B20-1,0,24,5))/24

Then formula for 2nd month is (30 rows down the spreadsheet)

=MMULT(OFFSET(O2,B50-1,0,24,5);OFFSET(O2,50-1,0,24,5))/24

ok, seems great but i'm not sure i'm following. Could you explain that a
little more. Thanks!

At the top of the pmatrix for each month if you included the month number
then you can use the Address function to create a reference offset from O2.

Thanks for your replay! I do not have the daily data though...

Don't use a calendar month, instead use a 30 day month.

I would like to create a number of matrixes from a list (covariance
between assets over time).
I put =MMULT(TRANSPOSE(O2:S25);O2:S25)/24 in excel and get a 5x5
covariance matrix calculated
on the dates 9301-9412 (January 93 until December 94 - 24
observations). I would like new matrix for every new months (moving
one month at a time). The next would refer to 9302-9501 or =MMULT
(TRANSPOSE(O3:S26);O3:S26)/24 and so on. The problem now is that I
cannot simply copy the matrix below the previous one because that one
is five rows down and refer to the date 9306-9505.

I would be very thankful if some one knows how to do, maybe with a
macro or in some other way.
