You're using this line over and over:

OFFSET($L$80;DAG;0;Nobs;aksjer)

Instead, define a name that refers to this statement and make it
short. You should be able to reduce the length of your formula in
this way.

become to long just before I'm finish.
A loop would have done it but I have no skills for to make it. what can I do
to get around it? have tryied in many ways but excel do not let me get an
answer to this.

What can I do?

Formula goes like this:

=MMULT(MINVERSE(MMULT(TRANSPOSE(
OFFSET($L$80;DAG;0;Nobs;aksjer):OFFSET($L$80;DAG;0 ;Nobs;aksjer)-TRANSPOSE(M-MULT(TRANSPOSE(
OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DA G;K$78;Nobs;aksjer));R80:-R109)/Nobs));
OFFSET($L$80;DAG;0;Nobs;aksjer):OFFSET($L$80;DAG;0 ;Nobs;aksjer)-TRANSPOSE(M-MULT(TRANSPOSE(
OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DA G;K$78;Nobs;aksjer));R80:-R109)/Nobs))/(Nobs-1));
MMULT(TRANSPOSE(
OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DA G;K$78;Nobs;aksjer));R80:-R109)/Nobs-U101)/

SUM(MMULT(MINVERSE(MMULT(TRANSPOSE(
OFFSET($L$80;DAG;0;Nobs;aksjer):OFFSET($L$80;DAG;0 ;Nobs;aksjer)-TRANSPOSE(M-MULT(TRANSPOSE(
